Local Variables unavailable [message #150591]

Hi folks,

I'm remotely debugging into an application running on a hp unix
box. As I understand it's a 64 bit hp unix server. Is this the reason that
I get the statement local variables unavailable as I try to step through
the code?

Or perhaps is the code compiled in such way that it's not available?

Thanks,
Mark.

Bingo. The code you're debugging must be compiled with debug info
enabled in order to access local variables. FYI, the standard Java
libraries (java.lang.*, com.sun.*) are NOT compiled this way.

Eric,

Thanks a million for your prompt reply. Could I ask a question? Is
there any javac or java function that you can run upon a class to see if
it's debug information has been included?

Thanks,
Mark.

You can run javap on the class with the -l option. That option will
print out line number and local variable info if it is present in the
..class file.

HTH,

Thanks for all your help Eric. I came across the javap tool and the jdb
tool just there. It could be a long night.
