[news.eclipse.dtp] How to grant custom ODA data source access to webapp

[Shannon Hardt <shardt@xxxxxxxxx>]

I am not sure if this is a question for the BIRT or DTP newsgroup, so I 
am cross-posting here as well.

I am having a deployment issue with a custom ODA data source and would 
appreciate any help.

I have implemented a custom ODA data source based on the BIRT JDBC data 
source. I have deployed the data source to my webapp that has the BIRT 
web viewer embedded. The data source is deployed in 
WEB-INF/platform/plugins. This data source uses class files that are 
located in jar files in the WEB-INF/lib directory.

When I launch a report that uses the data source, I get a 
java.lang.NoClassDefFoundError on the classes that are located in the 
WEB-INF/lib directory. The data source needs access to the class 
instances loaded by the webapp classloader.

How can I grant the data source access to the webapp class instances? 
Any help is appreciated.

Environment:
BIRT 2.3.2
Tomcat 5.5

Thanks,
Shannon
