I am creating dynamic VDB and in this process i am doing addSourceMapping like this-

modelMetaData.addSourceMapping(modelName, translatorName, "java:/XYZ-DS");

The VDB XML is getting created as per my code but while deploying this i get below exception

15:19:56,566 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-3) MSC00001: Failed to start service jboss.deployment.unit."xyz.1-vdb.xml".INSTALL: org.jboss.msc.service.StartException in service jboss.deployment.unit."xyz.1-vdb.xml".INSTALL: Failed to process phase INSTALL of deployment "xyz.1-vdb.xml"
