      Description

      There is a problem with the current packaging of the derby plugin that prevents
      derby classes from being found by the classloader when running an RCP
      application using java webstart.

      I rebuilt this plugin using a MANIFEST.MF that exports all the packages and
      specifies the classpath and it works.

      You can find my packaging here (SVN Web access)
      http://sharemedia.svn.sourceforge.net/viewvc/sharemedia/org.apache.derby.core/

      This problem is only a packaging issue, there is no need to do code changes.

      Scenario :
      1 - Create a new RCP product (plugin/feature/product)
      2 - Make the plugin depends on derby.core.
      3 - Add Class.forName( "org.apache.derby.jdbc.EmbeddedDriver").newInstance();
      in the code
      4 - Launch the product : I works.
      5 - Export the feature for webstart
      6 - Create a new feature for webstart, include & sign startup.jar, create the
      main jnlp, include the previous feature.
      7 - Export the 2nd feature for webstart
      8 - Launch the feature using the jnlp file. -> Class not found

      Cause :
      In the derby plugin, the packages are exported using the plugin.xml. This does
      not work with webstart.
      This can de fixed by adding a manifest.mf and exporting the derby packages in
      this file :

      Export-Package: org.apache.derby.authentication,
      org.apache.derby.catalog,
