replacing jars in plugins folder

hgk

Hi,

I want to replace com.ibm.icu_3.6.1.v20070906.jar with icu4j-3_8_1.jar in plugins folder because we are already using icu4j-3_8_1.jar in our webapp. But I am getting NullPointerException at
IReportEngine birtEngine = factory.createReportEngine(config);

It works fine and report gets generated when I replace com.ibm.icu_3.6.1.v20070906.jar with icu4j-3_8_1.jar in lib.

We don't want to use multiple versions of the same file in our product. How can I solve this?

Also we want to eliminate some of the jars such as org.eclipse.datatools.connectivity.oda.consumer_3.1.2.200710011.jar
in plugins because we are only using XML data source. I am getting the same NullPointerException when I try to eliminate the unwanted jars. Is there a way to eliminate unwanted jars in plugins folder?

Thanks for your help,
Bindu

Correction. We are using scripted datasource not xml datasource.
