Decompiling webMethods java class files is a violation of your customer software licensing agreement. Having said that, it is possible to decompile ANY java class file using a commonly available decompiler like JAD.
Look in ./packages/WmTN/code/classes/
The reason that you cannot see the “source” is because the source file is removed AFTER the package is compiled.
This is evident by comparing ./packages/WmTN/code/source/ to the directory ./packages/WmTN/code/classes/.
Look at some of your code. Your source is there unless you remove it.
