Decompile class, amend and re-add to ear

Question

I have an Ear file. I took a Java class file out, decompiled it and edited it.

I now want to recompile the new Java source file and re-add the resulting class file to my new Ear.

When I tried to recompile the new Java source file, the compiler complained about unrecognised classes, imports etc. I expected this.

My question is, can I recompile this new class and add it to my new Ear?

Answer 1

Perhaps the classes needed are also in the EAR. If not, you need to create stubs for all the classes, it needs.

Answer 2

Yes, you'll need to add all the dependencies to the classpath

Answer 3

I abandoned the idea of decompile, recompile and readd. I rebuilt the entire Ear from scratch.
