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/. The configuration steps are illustrated using a web application and adding a dependency on commons-dbcp library.

  1. Create a HelloWorld Dynamic Web project as given in Developing a Hello World Web application.
  2. 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.
    • Leave default options as-is and click Finish.
  3. To add a dependency on commons-dbcp library:
    • In Project Explorer view, right click on HelloWorld, select Maven -> Add Dependency.
    • Enter commons-dbcp as query, in Search Results select 1.3-SNAPSHOT-commons-dbcp-1.3-.. and click OK.
  4. To use a class from commons-dbcp library inside the web application's index.jsp:
    • Double click on HelloWorld -> WebContent -> index.jsp to open it in JSP editor.
    • Add the following code before the </body> tag.
    • Press Ctrl + S to save the changes.

      Make sure org.apache.commons.dbcp.DriverConnectionFactory class is resolved with no type not resolved errors.

  5. 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.
  6. 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.



    • Press Ctrl+S to save the file.
      Icon

      In Source tab, a dependency on geronimo/sharedlib//car would be added as below:

      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.

  7. 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:

  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:

    The file path used in the manifest Class-Path may differ based on the location of your maven2 repository.
