Hi,
I am trying to use jdb on my own application. After reading the
various docs I found, here is how I proceeded:
a) recompile all my classes with the '-g' option
b) replace TTY.class with the newer one (/dev/console prob)
c) run jdb
d) load my class (httpd.httpd)
e) set a breakpoint.
When I reach the breakpoint, the debugger (or whatever) gets an
exception, and kills the thread (!) So I am just not able to visit my
prog state at the breakpoint.
I have included below my full debugging session, in case I am doing
something wrong.
Anselm.
[BTW, I know lots of questions have been asked on jdb, but
unfortunatelly the mail archive at java.sun.com doesn't seem to
archive any more, so apologize if this has already been asked.]
