Java Class File Editor

Question

What is the most effective way I can decompile & Edit a class file? I really just want to edit one line of code in the file, however JBE (java ByteCode Editor) isn't letting me change a floating point constant.

Decompiling the class and recompiling will not work, as I have tried this, I get many dependency errors, and name errors. How can I go about this effectively?

Thanks

Answer 2

I am not sure it has been mentioned before or not but i used this http://classeditor.sourceforge.net/screenshot/index.html when i ran into the similar problem.

The tool is pretty decent, can help you look at the class files fields/methods etc. There is an option on the GUI which can be checked to edit the "values" of fields or soemthing which will reflect directly in class file.
