Are there any current plans to add the ability to "Attach to Process" to NB6.x? Or to create a more "integrated" Java<->JNI (C++) debugging experience? I'd love... And I mean... LOVE... the ability to debug a Java application's JNI methods easily from Netbeans. Currently, I use Data Display Debugger to attach to the running Java application so I can debug the JNI code, which is cumbersome. -- Dustin McCartney Chief Technology Officer DAM Entertainment LLC http://www.damentertainment.com Making this depend on 125513, since debugging JNI is really just a subset of debugging shared libraries. Most likely doing this will resolve the JNI issue. But I'll leave it open in case its not completely resolved by this issue. Integrated into 'main-golden', available in build *200808090201* on http://bits.netbeans.org/dev/nightly/ Changeset: http://hg.netbeans.org/main/rev/131629edf547 User: Gordon Prieur <gordonp@netbeans.org> Log: Attach to dynamic libraries (IZs #87677, #125513, #135721 and #125176). Preliminary work making it work on Solaris (although not heavily tested). Fixed with the following changesets:

It is possible? I don't know that any code changes will be required for this. What I think we should do is to do some mixed C/C++ and Java debugging (including a JNI shared library) to see how well this works. I attended a talk at JavaONE presented by an Eclipse user who did the equivalent of concurrent Java and gdb sessions to debug his JNI application. There are "gotchas" in doing this as the gdb session is really debugging the JVM the Java session is talking to. So what I'd realy like to see here, is a white paper we could publish about how to debug a JNI application and what pitfalls the user is likely to see and how to work around them. I almost assigned this to myself as I think it would be a very interesting project. However, since Nik is now the "owner" of gdb-lite I guess I'll let him have 1st chance. If you (Nik) don't want this then please assign to me or let me know you're not interested.
