Unable to display tree view Error when parsing an XML (Premature end of file)
Dear All.
Scenario: File to File using java mapping in SAP PI 7.4.
we are converting a raw text file into an xml file. For this purpose, we are using Java mapping in ESR.
Case 1:
When we run the scenario in Eclipse I can get the desired output
Case 2:
ESR when I test the Java mapping in OM, we are getting the below error:
Unable to display tree view; Error when parsing an XML document (Premature end of file.)
Below is the processing log:

Case 3:
when i place the file in source directory, the message getting delivered sucessfully but i can see empty file in target directory.
Please note: here i did't see any exception in processing log as mention below.
please note:SAP PI java version is: 1.6, and same jre used in eclipse project as well. in eclipse output xml is looks perfect.
please do needful where we did mistake, we've seen few blog which is refres tjhe same issue in message mapping, but we are facing this issue in java mapping.
