Java Mapping Issue

[Former Member]

Hi All,<br>

I am working on Java mapping in PI 7.1. Here in Java mapping i am trying to make my Flat file into XML. I have checked my program using Eclipse its working fine and got the XML from flat file. After that generated the jar file and imported in to the IR and use in the OperationMapping and tested. Here in SXMB_MONI i can see the payload in the Inbound message but after mapping step Nothing is there in the Payload.(its not generated the XML). and its not giving any error. I couldnt under stand the issue. <br>Can any plz help me on this? <br><br>

the code what i uesd:

Hi,

If it works in operation mapping test it should also work in scenario. May be a cache update issue?

[former_member200962]

can you post your code which is readable.....may be some formatting is needed...

[former_member200962]

enclose you code within your java mapping remove the spaces within the curly brackets

maintain line-breaks and it will be visible properly :).....leaving for the day....other experts can help you:)
