Accessing Spring beans from Quartz jobs

2010-04-27T07:27:00.000-07:00

http://cse-mjmcl.cse.bris.ac.uk/blog/2007/06/20/1182370280435.htm
The Spring Framework integrates with the Quartz scheduler in a way that makes Quartz much easier to use. Although in order to use Spring beans with your Quartz jobs you have to deviate slightly from the usual Spring "dependency injection" way of doing things. According to the Spring API this is necessary because Quartz itself is responsible for the lifecycle of its Jobs.

I was recently refactoring my use of Quartz and Spring in my feed aggregator web application. Rather than explain the internal workings of my application at this time, I will explain some features I discovered with reference to James Goodwill's recent simple example of using Quartz and Spring together. James shows how a "cron style" job can easily be created by configuring Quartz Job, trigger, SchedulerFactoryBean and loading up the application context.

VM setting in Eclipse

2010-03-29T14:06:00.000-07:00

http://wiki.eclipse.org/Eclipse.iniSpecifying the JVM

One of the most recommended options to use is to specify a specific JVM for Eclipse to run on. Doing this ensures that you are absolutely certain which JVM Eclipse will run in and insulates you from system changes that can alter the "default" JVM for your system. Many a user has been tripped up because they thought they knew what JVM would be used by default, but they thought wrong. eclipse.ini lets you be CERTAIN.

The following examples of eclipse.ini demonstrate correct usage of the -vm option.

Note the format of the -vm option - it is important to be exact:

The -vm option and its value (the path) must be on separate lines.

The value must be the full absolute path to the Java executable, not just to the Java home directory.

The -vm option must occur before the -vmargs option, since everything after -vmargs is passed directly to the JVM.

Windows Example

-showsplash

org.eclipse.platform

--launcher.XXMaxPermSize

256m

-vm

C:\Java\JDK\1.5\bin\javaw.exe

-vmargs

-Xms40m

-Xmx512m

classic pagination in Rails

2009-10-21T13:44:00.000-07:00

Action Pack pagination for Active Record collections

DEPRECATION WARNING: Pagination will be moved to a plugin in Rails 2.0. Install the classic_pagination plugin for forward compatibility:

script/plugin install svn://errtheblog.com/svn/plugins/classic_pagination

The Pagination module aids in the process of paging large collections of Active Record objects. It offers macro-style automatic fetching of your model for multiple views, or explicit fetching for single actions. And if the magic isn‘t flexible enough for your needs, you can create your own paginators with a minimal amount of code.

The Pagination module can handle as much or as little as you wish. In the controller, have it automatically query your model for pagination; or, if you prefer, create Paginator objects yourself.

Pagination is included automatically for all controllers.

For help rendering pagination links, see ActionView::Helpers::PaginationHelper.
Automatic pagination for every action in a controller

class PersonController < ApplicationController
model :person

paginate :people, :order => 'last_name, first_name',
:per_page => 20

Install via Subversion using the Ruby script/plugin install command. In the root of your Rails application structure
(where you can see the app/ vendor/ and public/ folders)
execute the following command:

ruby script/plugin install http://svn.napcsweb.com/public/reverse_proxy_fix

You will be prompted by the script to specify the version of Rails you're using. Select
the version that best matches your version of Rails and press the Enter key.
You should be prompted to enter the base url of your front-end server when you install
the plugin via script/plugin install. You should not include the trailing slash! For
example:

http://www.mydomain.com/typo

If that doesn't work for some reason, you can run the install.rb script in

vendor/plugins/reverse_proxy_fix

Or you can manually edit the file lib/config.rb and uncomment the BASE_URL line. (It should be the only line in the file. Enter the desired base url
that you would like the plugin to prepend to any generated URLs.

Pick the calendar you want to sync with Outlook. Now in the Private Address field click on the ICAL button. This will show you your private Calendar address. Copy this address to the clipboard.

Installing Ruby 1.8.7 (and other stuff) manually

2009-10-08T15:04:00.001-07:00

1. Download the windows binaries for Ruby 1.8.7 here: http://www.ruby-lang.org/en/downloads/ extract that to wherever you would like, I use c:\ruby. Then put c:\ruby\bin in your PATH environment variable.
2. Download the zlib package: http://www.zlib.net/zlib123-dll.zip and extract the zlib1.dll, rename it to zlib.dll and move it into your Windows\System32.
3. Download the iconv package: http://sourceforge.net/project/showfiles.php?group_id=25167&package_id=51458. Find and extract the iconv.dll into your Windows\System32.
4. Download the rubygems package and follow the instructions, basically extracting the package and running ruby setup.rb
5. Verify that everything works properly by trying a gem install rails, once that installs then do: rails test_project

Ruby 1.8 missing lib ( SSLEAY.dll , ZLIB.dll)

2009-10-08T14:18:00.000-07:00

Update: There is a new effort to create a decent Windows Ruby installer. You can get the new downloadable installers from http://rubyinstaller.org/downloads/ though as of August 2009 these are still in preview form. It seems from my brief experiment that you'll still have to set your PATH manually, as per my manual instructions below. This installer also promises a faster Ruby as it builds using superior tools, so might well be worthwhile if only for that. Below are my original manual instructions for installing Ruby on Windows, which should still be just as valid as they always were. The installer is probably worth a look though.

The following worked for me on Windows XP, but maybe I'm yet to run into problems I don't know I've got:

* Download the Windows binary release from http://www.ruby-lang.org/en/downloads/
* Unzip it, in my case to C:\ruby191\
* Also download readline.dll (e.g. from http://www.econsultant.com/dll-database-r/readline.dll-download.html) and put the DLL in C:\ruby191\bin
* Put C:\ruby191\bin and C:\ruby191\lib on your PATH

That got ruby working in a basic sense for me, but I wasn't able to install gems. If I tried, I got two errors in sequence: "The ordinal 277 could not be located in the dynamic link library SSLEAY32.dll" and "This application has failed to start because zlib.dll was not found."

The ssleay32.dll problem was solved by getting hold of a couple of DLLs and putting them in the right place, as follows:

* Download "Win32 OpenSSL v0.9.8k Light" from http://www.slproweb.com/products/Win32OpenSSL.html.
* Run the installer, but take note of the following:
* You can ignore any initial warning about not having Microsoft Visual C++ 2008 Redistributables.
* You can ignore any warnings about command prompts being open.
* Install to somewhere like C:\OpenSSL - it doesn't really matter, we just need a couple of DLLs.
* When prompted, choose to Copy OpenSSL DLLS to The OpenSSL binaries (/bin) directory.
* Once the installer has completed, you can go to C:\OpenSSL\bin (or wherever you installed it) and copy the two files ssleay32.dll and libeay32.dll to your Ruby bin directory, C:\ruby191\bin in my case.

The zlib.dll problem was solved by in much the same way:

* Download the compiled zlib 1.2.3 DLL from http://www.zlib.net/ (about two thirds of the way down the page).
* Unzip it to get the zlib1.dll file.
* Put that file in your Ruby bin directory, but rename it to zlib.dll

Et voila - gems can now be installed successfully! Note that you may have had copies of some of these DLLs in your \WINDOWS\system32 directory already (I certainly did) but the problem is that they are too old. I prefer to put the newer ones directly in the Ruby bin directory, so only Ruby picks them up and it can't break anything else on the system.

Rails 2.3 and Mysql 5.1

2009-08-06T13:44:00.000-07:00

The title says it all. I wish Ruby on Rails wasn’t so difficult to get set up on Windows. It sounds like most Ruby on Rails developers are Mac OS X or Linux users.

I was just trying to get a basic app set up with MySQL 5.1, Rails 2.3 and Ruby 1.8.6 and got this error when trying to run rake db:migrate:

rake aborted!
undefined method `each’ for #

I found an answer here:

http://www.nabble.com/rake-aborted!-undefined-method-%60each%27-for–%3CMysql:-td20760472.html

Looks like most people uninstalled MySQL 5.1 and went back to 5.0. People also seemed to have better luck with Postgresql.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11 CE-BFC1-08002BE10318

Hopefully these simple directions will help those who are not master computer techs like me:) God knows I couldn't get it right to save my life! But a light bulb went off in my head and this is how I did it. Almost embarassing to mention;

When looking for this file in device manager please consider the following Steps:

To resolve this problem, remove the affected filter drivers. To do this, follow these steps:

1. Click Start, type regedit in the Start Search box, and then click regedit in the Programs list.

If you are prompted for an administrator password or confirmation, type your password, or click Continue.

2. Locate, and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

ie., 1. Go to HKEY_LOCAL_MACHINE and click on it.
2. part of the sub directory will appear
3. then click on SYSTEM
4. You will then see Current Control Set click on it
5. And so on......get the picture now!
Whew! Now follow the rest of the directions and you should have any additional problems

Caution There can be many instances of the registry subkey that is mentioned in step 2. You must make sure that you are in the appropriate registry subkey before modifying the UpperFilters and the LowerFilters values. To verify that you are in the appropriate registry subkey, make sure that the Default data value is DVD/CD-ROM and the Class data value is CDROM.

3. In the right pane, right-click UpperFilters, and then click Delete.

4. Click Yes to confirm the removal of the UpperFilters registry entry.

5. In the right pane, right-click LowerFilters, and then click Delete.

6. Click Yes to confirm the removal of the LowerFilters registry entry.

7. Exit Registry Editor, and then restart the computer.

load files in jar

2009-05-20T06:23:00.000-07:00

If you use a filename, then the filename has to refer to a real file. But if you use a "resource name," that resource might be a file or it might be a component of a JAR (or theoretically something else altogether.)
The magic method(s) in this case are the family of loadResource() methods. For example, Class.getResource().
If youve got a class foo/bar/Test.class inside a JAR file, and also a foo/bar/Image.jpg, then inside the Test class you can refer to Image.jpg using
URL theURL = getClass().getResource("Image.jpg");
and then pass the URL to ImageIcon's constructor for example.

Inflater Deflater

2009-05-11T13:42:00.000-07:00

public class Inflater
extends Object
This class provides support for general purpose decompression using popular ZLIB compression library. The ZLIB compression library was initially developed as part of the PNG graphics standard and is not protected by patents. It is fully described in the specifications at the java.util.zip package description.

The following code fragment demonstrates a trivial compression and decompression of a string using Deflater and Inflater.

// Encode a String into bytes
String inputString = "blahblahblah??";
byte[] input = inputString.getBytes("UTF-8");

// Compress the bytes
byte[] output = new byte[100];
Deflater compresser = new Deflater();
compresser.setInput(input);
compresser.finish();
int compressedDataLength = compresser.deflate(output);

// Decompress the bytes
Inflater decompresser = new Inflater();
decompresser.setInput(output, 0, compressedDataLength);
byte[] result = new byte[100];
int resultLength = decompresser.inflate(result);
decompresser.end();

// Decode the bytes into a String
String outputString = new String(result, 0, resultLength, "UTF-8");

Rails 2.2 MySQL removed error SOLUTION
by protech_v2 » Mon Dec 15, 2008 8:04 pm

If at any point when you've upgraded to Rails 2.2. you get the following error on Windows:

"!!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql."

the problem is because MySQL 5.1 client library doesn't play well with Rails - the solution is simple however:

- download older MySQL client library, for example one from InstantRails: http://instantrails.rubyforge.org/svn/t ... bmySQL.dll

- copy the downloaded file to C:\Ruby\bin (or wherever you installed Ruby)

- restart MySQL server

That's it! Just thought I'd share this with others, lost me an hour of researching.

Good luck!

2009-05-03T18:02:00.000-07:00

What you do is create a select tag with the “select” method like so: (using the client/project scenario)

f.select(:client_id,

The next value you pass to the select method has to be an array of text/value pairs

like this: [ [ "Jason Johnson", 1], ["Trey Piepmeier", 2], ["Royall", 3] ]

In order to create this array, you do a find on your clients table and use Ruby’s “collect” method.

like so:

Client.find(:all).collect {|c| [ c.name, c.id ]}

So, altogether now:

f.select(:client_id, Client.find(:all).collect {|c| [ c.name, c.id ] })

WSDL2ruby

2009-04-09T12:48:00.001-07:00

1. Download soap4r from SVN.
svn co http://dev.ctor.org/svn/soap4r/trunk/bin soap4r
This will result in two files being downloaded - wsdl2ruby.rb and
xsd2ruby.rb. The one I used was the wsdl2ruby.rb.
2. Generate sample SOAP client file
ruby wsdl2ruby.rb --wsdl http://location_of_WSDL --type client
This will result in the creation of three files - default.rb,
defaultDriver.rb and WSClient.rb. The sample client file is
WSClient.rb. Inside this file, I found all the remote methods and "nil"
arguments being passed to them. For e.g., I had a remote method defined
as follows in my web-service:
string observe (string req_id, string[] names, string[] values);
The second and third argument for this file were vectors of strings.
In the ruby client file, this method was exposed as follows:
obj = WSSoap.new(nil)
parameters = nil
puts obj.observe(parameters)
So, even though my remote method should have three arguments, here
there is only one. According to nahi's email, I needed to construct a
hash table and pass that as the single argument.
3. Pass actual arguments.
name = ['CENTER', 'SPAN', 'SCALE', 'YREF', 'INTERVAL']
val = ['5.18 GHz', '2.95 MHz', '4.00', '-68.70', '30000']
parameters = {
'req_id' => '1',
'names' => {:string => name},
'values' => {:string => val}
}

result = obj.observe(parameters)
puts result.inspect

java:comp/env

2008-09-05T10:12:00.001-07:00

java:comp/env is a special context available to Java EE components. It provides the abstraction that each web application and ejb component has its own private naming context. The "java:comp/env" string is only used in the actual lookup() call. When defining the component dependency, it's up to the developer to pick a logical name that represents the dependency within its component naming context. There are recommendations for how to name things, e.g. prepending "jdbc" or "ejb" but those are only guidelines. The developer can choose any name he/she prefers.

Taking your example, if the code expects to do a lookup of a datasource dependency using ctx.lookup("java:comp/env/jdbc/mydb")

then the corresponding resource-ref would look like :

jdbc/mydb

javax.sql.DataSource

...

You're not the only one that has found dealing with java:comp/env a bit confusing. That's one reason the Java EE 5 platform provides an alternative to context lookups() in the form of resource injection.

You might find the following presentation about component dependencies useful :
https://glassfish.dev.java.net/javaee5/ejb/compdependencies_xmlforum_nov15.pdf

Regarding the portability of code using java:comp/env between Java EE implementations and stand-alone web servers like Tomcat, it's true that not all Java EE code can be used outside of Java EE. However, it's guaranteed to be portable to other Java EE implementations.

Creating the J2EE Application Client

A J2EE application client is a program written in the Java programming language. At runtime, the client program executes in a different virtual machine than the J2EE server.

The J2EE application client in this example requires two different JAR files. The first JAR file is for the J2EE component of the client. This JAR file contains the client's deployment descriptor and its class files. When you run the New Application Client wizard, the deploytool utility automatically creates the JAR file and stores it in the application's EAR file. Defined by the J2EE Specification, the JAR file is portable across all compliant J2EE servers.

The second JAR file contains stub classes that are required by the client program at runtime. These stub classes enable the client to access the enterprise beans that are running in the J2EE server. Because this second JAR file is not covered by the J2EE Specification, it is implementation specific, intended only for the J2EE SDK.

The J2EE application client source code is in j2eetutorial/examples/src/ejb/converter/ConverterClient.java. You already compiled this code along with the enterprise bean code in the section Compiling the Source Files.
Coding the J2EE Application Client

The ConverterClient.java source code illustrates the basic tasks performed by the client of an enterprise bean:

* Locating the home interface
* Creating an enterprise bean instance
* Invoking a business method

Locating the Home Interface

The ConverterHome interface defines life-cycle methods such as create. Before the ConverterClient can invoke the create method, it must locate and instantiate an object whose type is ConverterHome. This is a four-step process.

1. Create an initial naming context.

Context initial = new InitialContext();

The Context interface is part of the Java Naming and Directory Interface (JNDI). A naming context is a set of name-to-object bindings. A name that is bound within a context is the JNDI name of the object.
An InitialContext object, which implements the Context interface, provides the starting point for the resolution of names. All naming operations are relative to a context.

2. Obtain the environment naming context of the application client.

Context myEnv = (Context)initial.lookup("java:comp/env");

The java:comp/env name is bound to the environment naming context of the ConverterClient component.

3. Retrieve the object bound to the name ejb/SimpleConverter.

Object objref = myEnv.lookup("ejb/SimpleConverter");

The ejb/SimpleConverter name is bound to an enterprise bean reference, a logical name for the home of an enterprise bean. In this case, the ejb/SimpleConverter name refers to the ConverterHome object. The names of enterprise beans should reside in the java:com/env/ejb subcontext.

4. Narrow the reference to a ConverterHome object.

ConverterHome home =
(ConverterHome) PortableRemoteObject.narrow(objref,
ConverterHome.class);

Creating an Enterprise Bean Instance

To create the bean instance, the client invokes the create method on the ConverterHome object. The create method returns an object whose type is Converter. The remote Converter interface defines the business methods of the bean that the client may call. When the client invokes the create method, the EJB container instantiates the bean and then invokes the ConverterBean.ejbCreate method. The client invokes the create method as follows:

Converter currencyConverter = home.create();

Invoking a Business Method

Calling a business method is easy--you simply invoke the method on the Converter object. The EJB container will invoke the corresponding method on the ConverterEJB instance that is running on the server. The client invokes the dollarToYen business method in the following lines of code.

BigDecimal param = new BigDecimal ("100.00");
BigDecimal amount = currencyConverter.dollarToYen(param);

ConverterClient Source Code

The full source code for the ConverterClient program follows.

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import java.math.BigDecimal;

public class ConverterClient {

public static void main(String[] args) {

try {
Context initial = new InitialContext();
Object objref = initial.lookup
("java:comp/env/ejb/SimpleConverter");

ConverterHome home =
(ConverterHome)PortableRemoteObject.narrow(objref,
ConverterHome.class);

Converter currencyConverter = home.create();

BigDecimal param = new BigDecimal ("100.00");
BigDecimal amount =
currencyConverter.dollarToYen(param);
System.out.println(amount);
amount = currencyConverter.yenToEuro(param);
System.out.println(amount);

System.exit(0);

} catch (Exception ex) {
System.err.println("Caught an unexpected exception!");
ex.printStackTrace();
}
}
}

Compiling the Application Client

The application client files are compiled at the same time as the enterprise bean files, as described in Compiling the Source Files.
Packaging the J2EE Application Client

To package an application client component, you run the New Application Client wizard of the deploytool. During this process the wizard performs the following tasks.

* Creates the application client's deployment descriptor
* Puts the deployment descriptor and client files into a JAR file
* Adds the JAR file to the application's ConverterApp.ear file

After the packaging process you can view the deployment descriptor by selecting ToolsDescriptor Viewer.

To start the New Application Client wizard, select FileNewApplication Client. The wizard displays the following dialog boxes.

1. Introduction dialog box
1. Read the explanatory text for an overview of the wizard's features.
2. Click Next.
2. JAR File Contents dialog box
1. In the combo box, select ConverterApp.
2. Click Edit.
3. In the tree under Available Files, locate the j2eetutorial/examples/build/ejb/converter directory.
4. Select the ConverterClient.class file and click Add.
5. Click OK.
6. Click Next.
3. General dialog box
1. In the Main Class combo box, select ConverterClient.
2. Verify that the entry in the Display Name field is ConverterClient.
3. In the Callback Handler Class combo box, select container-managed authentication.
4. Click Next.
5. Click Finish.

Specifying the Application Client's Enterprise Bean Reference

When it invokes the lookup method, the ConverterClient refers to the home of an enterprise bean:

Object objref = myEnv.lookup("ejb/SimpleConverter");

You specify this reference as follows.

1. In the tree, select ConverterClient.
2. Select the EJB Refs tab.
3. Click Add.
4. In the Coded Name column, enter ejb/SimpleConverter.
5. In the Type column, select Session.
6. In the Interfaces column, select Remote.
7. In the Home Interface column, enter ConverterHome.
8. In the Local/Remote Interface column, enter Converter.

PC World's 50 Best Tech Products of All Time

2007-04-05T07:57:00.000-07:00

The Beatles. Citizen Kane. Muhammad Ali. Many have laid claim to being the "best ever" in their respective fields of work, but only one can top the list. And the same is true when it comes to technology.

So what's the best tech product to come out of the digital age? And what qualifies a product as being "best"? First and foremost, it must be a quality product. In many cases, that means a piece of hardware or software that has truly changed our lives and that we can't live without (or couldn't at the time it debuted). Beyond that, a product should have attained a certain level of popularity, had staying power, and perhaps made some sort of breakthrough, influencing the development of later products of its ilk.

So after considering hundreds of products and engaging in many hours of painstaking debate, PC World presents the 50 best tech products. Note that we're looking only at technology that has arisen since the dawn of the personal computer, so don't expect to see the cotton gin and the transistor radio on the list. Instead, you'll find gear that, in all likelihood, you used yourself at one point or another--and, in many cases, products you're still using today.

From the article: 'The TGV, short for "train a grande vitesse," as France's bullet trains are called, is made up of three double-decker cars between two engines. It has been equipped with larger wheels than the usual TGV to cover more ground with each rotation and a stronger, 25,000-horsepower engine, said Alain Cuccaroni, in charge of the technical aspects of testing
