Print variables in java jdb debugger

Question

Is it possible to view variables, passed as arguments in function, if class was compiled without debug flag? I successfully put breakpoint on call, but after that i don't know how to view arguments value. I don't have good source code, soft is obsuficated. Function like this: void a(int var1, boolean var2) - so, i want print var1 & print var2.

Compile code with javac -g MyClass.java. This will allow you to watch local variables when using jdb MyClass

I use Eclipse Java debugger. I am able to view arguments passed to method in "Variables" view.

I don't have source code, only compiled(without debug option) class. I try eclipse and can't find how to debug without source there.

You can use some decompiler like JAD , to get sources. You can install Jode plugin on eclipse for decompiling.
