Setup:
...
In order to configure GEP to publish Maven dependencies as shared library, you will need to install Maven Integration for Eclipse. To install m2eclipse plugin, follow the instructions at given at http://m2eclipse.codehaus.org/
...
Step-1: Create a Web-App
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.
...
. The configuration steps are illustrated using a web application and adding a dependency on commons-dbcp library.
- Create a HelloWorld Dynamic Web project as given in Web applications.
- Enable Maven 2 support for the web-app project
...
- as given below:
- In Project Explorer view, right click on
...
- HelloWorld, select
...
- Maven -> Enable Dependency Management

...
- .
- Enter
...
- commons-dbcp
...
- as query,
...
- in
...
- Search Results
...
- select

- 1.3-SNAPSHOT-commons-dbcp-1.3-..
...
- and click
...
- OK
...
- .
...
- To use a class from commons-dbcp
...
- library inside web-app's index.jsp:
- Double click on
...
- HelloWorld -> WebContent -> index.jsp
...
- to open it in JSP editor.
- Add
...

errors.
...
- 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.
- 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

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.
...

...
to save the changes.
Step-6: Redeploy and Run the web-app
...
- 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 maven dependency is indeed added as a shared library:
...
- Verify that a file
- HelloWorld.eclipse.jar
...
- is created under <geronimo_home>/var/shared/lib.
- Verify that the Manifest.mf file
...
- in HelloWorld.eclipse.jar contains the following:
Code Block Manifest-Version: 1.0
...
Class-Path: file:/E:/m2repo/commons-pool/commons-pool/1.3/commons-pool
...
-1.3.jar file:/E:/m2repo/commons-dbcp/commons-dbcp/1.3-SNAPSHOT/commo
...
ns-dbcp-1.3-SNAPSHOT.jar
Note The file path used in the manifest Class-Path may differ based on the location of your maven2 repository.
