Configuring GEP to publish POJO projects as shared library is illustrated using a Web application and adding a POJO project as a dependency. In order to create a new Web project and publish its dependency on a POJO project as shareld library, follow the steps given below:

1. Create a HelloWorld Dynamic Web project as given in Developing a Hello World Web application.
2. Create a POJO project as given below:
   • Click File -> New -> Project.
   • Select Java Project and click Next.
   • Enter CurrencyConverterPojo

Setup:
Sun Java v1.5.0_11 + Apache Geronimo v2.0.2
Eclipse 3.3.1 + WTP2.0.1 + Geronimo Eclipse Plugin v2.0

Step-1:
Follow the instructions at <link to be added here> to add Geronimo 2.0 server runtime into WTP, and to create & deploy an "HelloWorld" Dynamic Web project.

Step-2: Create a POJO project

1. • as class name

...

1. • and click Finish

...

1. • .
   • Replace the

...

1. • content of CurrencyConverjer.java with the contents from CurrencyConverter.java.
   • Press Ctrl + S to save changes.
2. Add POJO project into web-app's Java Build Path as given

...

1. below:
   • In Project Explorer view, right click on HelloWorld, and click Properties.
   • Click Java Build Path and then switch to Projects tab.
   • Click Add. Select CurrencyConverterPojo as the project to be added and click OK. Click OK again.

2. To use POJO inside web-app's index.jsp:
   • Double click on HelloWorld -> WebContent -> index.jsp to open it in JSP editor.
   • Add the following code before the </body> tag.

     Code Block
     <br>100 USD == <%= myPackage.CurrencyConverter.dollarToRupees(new java.math.BigDecimal(100.0)) %> INR

   • Press Ctrl + S to save the changes.
3. Enable in-place shared library support in Server editor as given below:
   • In Servers view, double click on Apache Geronimo v2.1 Server at localhost to open the server editor.
   • In the server editor, under Test Environment, select Enable in-place shared library support.

   • Press Ctrl + S to save the changes.
4. To add a dependency on org.apache.geronimo.configs/sharedlib//car in geronimo-web.xml:
   • Double click on HelloWorld -> Web Content -> WEB-INF -> *geronimo-web.xml* to open it in Geronimo Deployment Plan Editor.
   • In General tab, select Add a run time dependency to Geronimo's shared library.
     
     Image Added
   • Press Ctrl+S to save the file.

     Note

     In Source tab, a dependency on geronimo/sharedlib//car would be added as below: Code Block <sys:dependency> <sys:groupId>geronimo</sys:groupId> <sys:artifactId>sharedlib</sys:artifactId> <sys:type>car</sys:type> </sys:dependency> This is due to a current bug in Geronimo Deployment Plan Editors. Change <sys:groupId> from geronimo to org.apache.geronimo.configs and press Ctrl + S to save the changes.

5. To run the HelloWorld application:
   • Right click on HelloWorld, click Run As -> Run on Server.
   • Select Apache Geronimo v2.1 Server at localhost and click Finish. This will run the application and the welcome page will open in a browser inside eclipse.

Use the steps below to verify that the dependency on POJO project is indeed added as a shared library:

1. Verify that a file HelloWorld.eclipse.jar is created under <geronimo_home>/var/shared/lib.
2. Verify that the Manifest.mf file in HelloWorld.eclipse.jar contains the following:

   Code Block
   Manifest-Version: 1.0 Class-Path:file:/E:/IDEworkspaces/m2eclipseSharedLib/CurrencyConverte rPojo/bin/

   Note
   The file path used in the manifest Class-Path may differ based on the location of your workspace directory.
