remote debugging with WTK emulator

[Zandis Murāns]

I am getting stuck with getting jdeveloper's remote debugger to work with WTK emulator.
Here's how I run my WTK emulator:

emulatorw.exe -gui -Xdescriptor "x.jad" -Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=8787 -Xdevice:QwertyDevice

When emulator is up and running, now I go to jdeveloper and try to connect JPDA remote debugger to port 8787... It connects fine and here's what I get in jdeveloper's console right after connecting:

Debugger attempting to connect to remote process at localhost 8787.Debugger connected to remote process at localhost 8787.
Debuggee process virtual machine is KVM.
Deadlock detection is not supported by the debuggee virtual machine.

Now, everything looks normal except if I set any break point in my midlet source, it just does not hit...

I've tried the same with netbeans debugger. Basicly, happens the same but extra message in netbeans console:

Not able to submit breakpoint LineBreakpoint x.java : 11, reason: Line number information is missing in the class file test.x.
Invalid LineBreakpoint x.java : 11

Yes, the jar file is packed with the same compiled midlet that is open in IDE and I set breakpoint at correct line.

Here's midlet source:

package test;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

public class x extends MIDlet implements CommandListener {
    private Command exitCommand;
    private TextBox tbox;

    public x() {
        exitCommand = new Command("Exit", Command.EXIT, 1);
        tbox = new TextBox("cau", "aaa!", 25, 0);
        tbox.addCommand(exitCommand);
        tbox.setCommandListener(this);
    }

    protected void startApp() {
        Display.getDisplay(this).setCurrent(tbox);
    }

    protected void pauseApp() {}
    protected void destroyApp(boolean bool) {}

    public void commandAction(Command cmd, Displayable disp) {
        if (cmd == exitCommand) {
            destroyApp(false);
            notifyDestroyed();
        }
    }
}

My breakpoint is set on line:

tbox = new TextBox("cau", "aaa!", 25, 0);

, but it just does not hit.

If I run my midlet in debug mode in Netbeans, debugging works just great.
If I do attach debugger to remote process, it just does not hit.

Any ideas how to get this working? :confused:

Any chance that your source code in the IDE isn't a match for the remote code?

This is a common problem when doing remote debugging. You set a breakpoint, but the breakpoint isn't where you thought it was because the line numbers for the code on the target machine don't match the line numbers on the debugging machine's source project.

No, absolutley no chance of that...
