Derby Eclipse plug-in shouldn't use Jar packages in the plugin for better usage 
in RCP Applications
---------------------------------------------------------------------------------------------------

         Key: DERBY-631
         URL: http://issues.apache.org/jira/browse/DERBY-631
     Project: Derby
        Type: Improvement
    Versions: 10.1.1.0    
 Environment: Eclipse RCP
    Reporter: Bernd Lachner
    Priority: Minor


I use the Derby Eclipse Core plug-in in an Eclipse RCP Application. If I 
disable "Unpack the plug-in archive after the installation" in the feature of 
my RCP Application for the Derby core plug-in, the Derby classes can't be found 
by "Class.forName("org.apache.derby.jdbc.EmbeddedDriver");" after I deployed 
the Application and try to start it. It only works when the Derby Core plug-in 
is unpacked. It seams, the reason for this behaviour is, that the 
org.apache.derby.core_10.1.1.0.jar contains other jar files (derby.jar, 
derbyclient.jar, ...) and Eclipse RCP can't handle this. But for example for 
Java Web Start it would be necessary that the Derby Core plug-in is also 
packed. Maybe in future versions of the Derby Core plug-in Jars in Jars can be 
avoided to solve this problem.
