========================================================.

Environment:
===========
TIBCO Runtime Agent(TRA) 5.7.x ,TIBCO Designer 5.7.x , TIBCO ActiveMatrix BusinessWorks 5.9.x


Cause:
============.
The issue is  due to conflicting “xerces” jars.loaded by Designer. Because of this the process would hang.


Resolution:
==============
1). Goto tibco.class.path.extended in your  designer.tra .

2). Add jar file as first entry  to the extended path &ltTIBCO_HOME>/tpcl/5.7/lib/xercesImpl.jar

3. Save the changes and restart Designer.
