Hi Nirjar,
The jar is actually not developed by me. So I am not sure regarding pasting that.
Thanks for sharing about catalog.xml . I figured out that my catalog.xml file is present in my assembly jar file.
Anyways, I have figured out my problem. As in MII 12.2, I was trying to upload the zip folder of jars and not separately as required in MII 12.1. I am now unzipping the zip file and uploading the main jar as assembly file and other jars as dependency files. Its works in this way.
Thanks.
Regards,
Minakshi.
