Problems with IMachineDebugger

[Wldz]

Hello,
I just want to know how to initialize the IMachineDebugger object in java? As I am using Virtualbox API 4.3. I want to use dumpGuestCore method of this class. Please help me out.

Which type of bindings are you using (WebServices, XPCOM, MSCOM)?
Do you already have some code, even if it doesn't work?

I am using XPCOM binding. I am just stuck here on the initialization step.

Code: Select all

        IMachineDebugger dump = new IMachineDebugger(null);
        dump.dumpGuestCore("wal", "s");

this what i am trying to do so far

Ok, I understand the issue. You cannot create the object yourself, you need to retrieve it from the API objects. Have you read the introduction section in the SKDRef.pdf file that comes with the SDK? Esepcially section 10.3 which deals with Java specifics.
The IMachineDebugger can be obtained via the IConsole object, which is accessible via a mutable IMachine object from a ISession obejct. so in pseudo-code, it would look something like this :

Code: Select all

ISession sess = VirtualBoxManager.getSessionObject();
IMachine vm = IVirtualbox.getMachine();
vm.lock(sess,LockType.Shared);
IMachineDebugger dbg = sess.getMachine().getConsole().getDebugger();
// do stuff
sess.unlockVm(); // very important!

Thanks for your help and yes I had gone that chapter but I will again look through it..

I am also facing some problems in opening the the dump file which I get using this method.

Code: Select all

dump.dumpGuestCore("/home/waleed/asdf","");

Can you tell me how to open this output file to whats really in there in the file.

I have no knowledge of the dump format. If you need a fast answer, I would suggest you ask on the dev IRC channel or the dev mailing list.
Else, devs tend to come read this forum from time to time.
