How to get Java Decompiler / JD / JD-Eclipse running in Eclipse Helios

Question

Java Decompiler (JD) is generally recommended as a good, well, Java Decompiler. JD-Eclipse is the Eclipse plugin for JD.

I had problems on several different machines

Answer 1

I am using Eclipse 3.7 Indigo and Windows 7 64-bit:

What I did was to install the Microsoft Visual C++ 2008 SP1 Redistributable Package as suggested by the site and reminded by @Universalspezialist.

Then install the plugin as stated in the site: http://java.decompiler.free.fr/?q=jdeclipse

Go to preference, then find "File Associations" Click on the *.class, then set the "class File Editor" as default.

Restart Eclipse perhaps? (I did this, but I'm not sure if it's necessary or not)

Answer 2

if you need to decompile standalone jar try JD-GUI by the same autor (of JD-Eclipse). It is a standalone application (does not need eclipse). It can open both *.class and *.jar files. Interesting enough it needs .Net installed (as do JD-Eclipse indeed), but otherwise works like a charm.
