Hi all,

I am having par file, which is having some JSPDynapge classes. After extracting par file, I can see one jar file.

Can anyone explain me how to decompile jar file and get the classes into the NWDS and modify them.

Thanks in advance.

Extract the jar with any winzip/winrar software and decompile the .class files with Jadclipse, it's an eclipse plugin that can be downloaded <a href="">from here</a>

Once modified, compile the source code, pack it to jar again using the jar utility command and add it to the par.

In case these are SAP files you are modifying I would deeply advise you not to.

Hope it helps,
