I just found this cool Java Decompiler, JD from Alon Aizenberg’s Tech Blog. It is just a single small exe (682kb) that can open jar files and decompile classes in an instant. The look and feel of the application is close to Eclipse. But it is blazingly fast. There is an Eclipse plugin too. Check it out.
Long time ago I posted about needing a tool like Reflector for Java. I needed a tool that I can use to quickly open a jar and browse the classes in it. JD comes pretty close. It would be perfect if it showed the outline of classes too.
