Hi Felix,
after diving into the topic I got the following understanding. Please
correct me if I'm wrong.
o In the Eclipse preferences one needs to map *.esp files to the
JavaScript content type.
o Now its possible to set a breakpoint in the esp file.
o Next one needs to load the esp script file in the "Breakpoints" view.
o Starting the debugger now calls new
...jsdt.debug.internal.rhino.jsdi.VirtualMachineImpl() which sends a
scripts command request [1] to the
...jsdt.debug.internal.rhino.debugger.RequestHandler on the server side.
That handler calls
...jsdt.debug.internal.rhino.debugger.RhinoDebuggerImpl.getScriptIds().
The only location that sets the script id's is the
handleCompilationDone() method of RhinoDebuggerImpl. I only see that
indirectly called by
oas.scripting.javascript.helper.SlingGlobal.require() and .execIdCall().
As the latter is a method from org.mozilla.javascript.IdFunctionCall
there are too many possible callers and I cannot easily find out if the
trigger to load the JavaScript files is already there somewhere.
I guess we only need to trigger the handleCompilationDone() methode
somewhere in Sling but I don't know enough about Sling to decide where
that would fit in or what to configure to make it fit. Maybe it could be
triggered during
...scripting.javascript.internal.RhinoJavaScriptEngine.eval(). Do you
have an idea?
Best,
Sandro

Hi Felix,
that was fast. I'm impressed.
Thanks for the tutorial. I can connect too but the debugger also doesn't
stop at my breakpoint like in your case.
Best,
Sandro
PS: Just in case somebody else want to follow: The export in step 5 is
"org.mozilla.javascript.debug".

Hi Felix,
thanks for the feedback.
The Swing debugger GUI doesn't seem to work in this case as it cannot
open e.g. the explorer.esp file. It says:
"Syntax error (.../explorer.esp#83)"
This refers to the line containing only "<form action="#">" which is
correct in my opinion.
I would expect the line to be correct, but I must admit to not have
used
this for quite some time, so ... this may really not properly work
(unfortunately).
I also tried the "Eclipse IDE for JavaScript Web Developers" from
http://www.eclipse.org/downloads/ as it contains debugging support for
Rhino (http://wiki.eclipse.org/JSDT/Debug). But it doesn't work out of
the box. Even though it is based on JPDA I guess there needs to be
something Rhino specific installed on the serverside.
Sounds interesting. Would be exactly what I had in mind ;-) Will
investigate.
It'd be better if this page wasn't blank:
http://wiki.eclipse.org/JSDT/Debug/Embedding_Rhino_Debugger
Yes, well, I got it sort of working with a bit hacking ....
1. deploy two JSDT bundles into Sling:
org.eclipse.wst.jsdt.debug.rhino.debugger
org.eclipse.wst.jsdt.debug.transport
(ignore for now that these bundles use Require-Bundle
and export internals ...)
2. upgrade Sling Rhino reference to 1.7R2
3. inside Sling add a dependency to the
org.eclipse.wst.jsdt.debug.rhino.debugger project checked
out from Eclipse CVS
4. In the SlingContextFactory constructor instantiate a RhinoDebugger
with a connector string (e.g.
"transport=socket,suspend=n,address=9000"), register it as a
listener and start the RhinoDebugger
5. Export org.mozilla.javascript.debugger package and add an
optional import to org.eclipse.wst.jsdt.debug.rhino.debugger in
the pom.xml
6. build and install the Sling Javascript bundle
Now you can connect to this Debugger with Eclipse ... And yes, I can
connect but I cannot yet cope with filenames...
I create a project and a folder linked to a WebDAV mounted Sling folder
and can then set breakpoints. The problem is, that Eclipse seems to
prefix all script names with the project and folder name and thus is not
able to match the names of executed scripts to apply break points ...

Hi Sandro,
The best solution (which I once considered working on a long time ago
but never got around to implement) is to have Rhino debugging
support in
Eclipse.
But for now, you may set the
"org.apache.sling.scripting.javascript.debug" framework property
(e.g.
in the sling.properties file) to true. When this property is set
to true
Rhino will launch the Swing debugger GUI (on the server system)
once the
Rhino ScriptEngineFactory is started.

Hello,
I'm trying to get into the Sling Explorer and I'm wondering how
(or if)
you guys debug these esp scripts? While the Eclipse debugger
stops in
jsp files it doesn't stop in esp files as they don't contain Java
code.
Is there a special JSR-223 debugger plugin or some trick I don't
know
of?
Best,
Sandro
