Cannot process data source extension configuration

[blerim2709]

Hello, When trying to generate a document with our Java application using birt 2.3.0 we get this error:

[11/08/22 22:40:41:345 GMT-10:00] 000002c0 odaconsumer E org.eclipse.birt.data.engine.odaconsumer.Driver doGetDriverManifest Cannot process data source extension configuration. java.lang.IllegalArgumentException: org.eclipse.datatools.enablement.oda.xml at org.eclipse.datatools.connectivity.oda.util.manifest.ManifestExplorer.getExtensionManifest(ManifestExplorer.java:200) at org.eclipse.birt.data.engine.odaconsumer.Driver.doGetDriverManifest(Driver.java:147) at org.eclipse.birt.data.engine.odaconsumer.Driver.findDataSourceExtensionConfig(Driver.java:123) at org.eclipse.birt.data.engine.odaconsumer.Driver.getDriverExtensionConfig(Driver.java:78) at org.eclipse.birt.data.engine.odaconsumer.Driver.getExtensionConfig(Driver.java:60) at org.eclipse.birt.data.engine.odaconsumer.Driver.getDriverHelper(Driver.java:93)

We are using : Java 1.8 Birt 2.3.0 (we can't upgrade to a greater version for now) Websphere

The jar org.eclipse.datatools.enablement.oda.xml_1.1.0.jar is present in WEB-INF/platform/plugins

I can make it work when using Tomcat with Eclipse but i get this error with Websphere.

Anyone has an idea about how to solve this issue ?
