Remote javascript debugger [message #568024]

Hi,

I'm trying to get the remote javascript debugger to work using e4 M3 and rhino 1.7R2. I've added the code as described in the wiki:

String rhinoDebug = System.getProperty("rhino.debug");
if ( rhinoDebug != null) {
RhinoDebugger debugger = new RhinoDebugger(rhinoDebug);
debugger.start();
ContextFactory.getGlobal().addListener(debugger);
}

And i'm able to connect to the debugger from eclipse and get a thread list. However the debugger does not suspend on any breakpoints. I am assuming this is because it cannot match the source files to the locations my scripts return.

I've set the sourcefiles location to projectname/path and the source lookup directory to Workspace (as my scripts come from several projects). I've also tried paths relative to a single project and using that project as the lookup dir.

I'm using Windows Vista and jdk 1.6.0-18.

Any ideas?

Thanks,
Jeroen

Hi Jeroen,

You're guessing right in that you're likely having problems with source
lookup. At the moment the source lookup is setup to work well with
JavaScript bundles but more general file based source lookup is not reliable
without knowing how the internals work. This is obviously something we're
working on improving right now in HEAD to ensure it demoes well at
Eclipsecon however for now your best bet is to break on script load and then
set your breakpoints in each script. After you've loaded the script once
this approach will generally work from run to run.

Hey,

Did you manage to solve this problem some how? I'm facing the exact same problem.

I'm also trying to understand what Simon means in his reply. I can break on script load but then what?
