Hello Eclipse - BIRT community,

We are trying to convert JSON to POJO and then use this POJO data source in BIRT. We are passing json string as a report parameter. We have also linked the same to dataset parameter.
Conversion of json string to java objects works when run individually in eclipse. However when we run the report, we receive the following exception:


org.eclipse.birt.report.engine.api.EngineException: Cannot execute the statement. org.eclipse.datatools.connectivity.oda.OdaException ; java.lang.reflect.InvocationTargetException

Stack Trace:
org.eclipse.birt.report.engine.api.EngineException: Cannot execute the statement.
