greetings,

I am not much into cracking. My target is a (flexlm 9.2) DLL called by a java application via JNI. IDA quickly tells me where to set the breakpoint. In SI I declare the DLL as an export, set my BPX and I am done.

Can I (how) set a similar BP in Olly? The application is started from .exe java starter and the DLL belongs to the corrosponding javaw.

cheers JIT

p.s. a standalone debugging of the DLL won't help me

bud_gd would you please mind the words when you post on a public forum
i see this is your second post with the big F and in what way the reply helps the poster ???
what he does is his concern not yours or mine as long as he doesnt cross certain thin invisible lines

to jit
you need to set a bp on on a dll function in ollydbg
view-->executable modules -->find your dll -->select it and right click -->view names --> find the function --> hit f2 and you are done with the break point for the session

if you need the break point to be persistent for all further session
analyze the module and hit f2 after analysing ollydbg will save your break point

if the dll is not loaded by default but loaded dynamically using load library
option --> debugging option --> event ---> stop on new module load
when it stopped on your module set your bp

also you can use commandline plugin to
set bps on dlls apis
bp mycrapdll.myuselessfunction
