Hi Padma/Vinod
How did you managed to resolve the issue?
I am also facing the similar issue.
When i run the transaction, the java console gives the error as - "error Serializing Context Item Input:R/3Name"
in the Transaction manager i can see that the Transaction is complete but from the Workbench it takes a lot of time to show the result.
Thanks in advance,
Sanjeev Sharma
