I am having trouble migrating a birt project into a spring project. So far, I have birt integrated and working on generating a report. However, I am getting the following NPE:

Caused by: java.lang.NullPointerException
   at org.eclipse.datatools.connectivity.oda.spec.manifest.ResultExtensionExplorer.addAllExtensions(ResultExtensionExplorer.java:541)
   at org.eclipse.datatools.connectivity.oda.spec.manifest.ResultExtensionExplorer.(ResultExtensionExplorer.java:122)
   at org.eclipse.datatools.connectivity.oda.spec.manifest.ResultExtensionExplorer.getInstance(ResultExtensionExplorer.java:86)
   at org.eclipse.birt.data.engine.impl.DataEngineImpl.getValidationContext(DataEngineImpl.java:764)
   at org.eclipse.birt.data.engine.impl.OdaDataSetRuntime.(OdaDataSetRuntime.java:56)

I can include more of the stack trace if it helps. It seems that within ResultExtensionExplorer, this line of code:

IExtension[] extensions = ManifestExplorer.getExtensions( DTP_ODA_DYNAMIC_RESULT_SETS_EXT_POINT );

is returning null. I'm guessing that there is some sort of configuration that I have not migrated properly into the destination project. Can anyone point me to possible configurations I should be looking at?

John,

Can you give some more detail on how you integrating the two? What
version of spring and what version of BIRT?

I fixed it, sorry. Somehow my classpath got mangled and the birt runtime jar was not available.
