how to work with JMS service using workbench

Hi All,

I am using JMS service under Foundation that can invoke a JMS queue,
but while specifying the properties under connection I am getting an error message saying that "Initial context is not available". I am using weblogic 9.2 and I configured JMS connection factory.
now in workbench, under JMS service > properties >
connection factory(literal value), I can't find the configured connection factory under this ..?
can someone help me how to resolve this..?

regards,
sudheer.
