subreportClientDoc.getDatabaseController().setDataSource(resultSet_subReport, tableName_subReport , "resultTbSubReport");
While executing the above line, we are getting the below error message.
com.crystaldecisions.sdk.occa.report.lib.ReportSDKException: java.lang.NullPointerException---- Error code:-2147467259 Error code name:failed
Both resultSet_subReport and tableName_subReport variables are not NULL.
How do we find the root cause of this error?
Thanks,
