Re: [jdt-debug-dev] JavaMethodEntryBreakpoints

You should use qualified type signature format for method signatures. We compare against the runtime (resolved) signature, not the development time (unresolved) signature. The resource you specify does not effect the installation of the breakpoint - it only defines what resource the associated breakpoint marker will be persisted with in the workspace. Generally, if the associated java element (method, type, etc.), is contained in a file in the workspace - that resource should be specified. For elemnets not in the workspace, it is up to the client to specify an arbitrary resource - for example the workspace root, or associated project.
I tried an example to suspend in junit.samples.VectorTest. I added the constructor "VectorTest(String)" contructor, and created a breakpoint like this:
JDIDebugModel.createMethodEntryBreakpoint(resource, "junit.samples.VectorTest", "<init>", "(Ljava/lang/String;)V", -1, -1, -1, 0, true, attributes);
This worked OK for me.

Sorry, but I forgot to mention that the same routine works for any other method (not constructors, that is).

Thanks for the advice, but even after I changed "FileReader" to "<init>", the bahavior does not change: the breakpoint is created (it is shown in the "breakpoint"-list of the debugging perspective), but if I select "debug as JUnit Test", the execution is _not_ interrupted upon reaching the breakpoint (and it is definitely reached).
However, I found out, that I was using the wrong resource. But I changed "FileReader" to "DummyTest" (which is a JUnit test class created in the default package) and tried to set a breakpoint on its constructor using the described method. And that did not work either (same behavior). If I set the breakpoint manually (i.e. by double clicking), it works fine.
So again, this is my statement:
JDIDebugModel.createMethodEntryBreakpoint(resource,
"DummyTest",
"<init>",
"(QString;)V", // It's really QString; here, not "Ljava.lang.String;" as in java.io.FileReader
0, -1, -1, 0,
true, attributes);
The breakpoint appears in the breakpoint list, but execution is not paused upon reaching it. Why?
And, something completely different: How _do_ I get the correct resource of any java file that does not neccessarily have to be in my workspace (if you know a quick how-to, I'd appreciate hearing it, however, I have not looked into that problem yet, and I suppose it could really be simple).
Once again, I thank you very much for your help and your patience.

(Forgot to mention)...For a method breakpoint, the line numebrs/source positions are simply used to render the breakpoint in the editor.

It looks like you are specifying the wrong name for the method - i.e. "FileReader". If you are referring to a constructor, you should use "<init>".

Hello,
I am trying to programatically set a JavaMethodEntryBreakpoint.
Can this be done _without_ knowing the line number of the method
definition? It does not seem to work for me.
This is, what I do:
I have an IResource object and a name of a method, where I'd like to
set a breakpoint. Say, for example "java.io.FileReader" (and let's
suppose, that I do not have the source code for that class).
Aside: If I do have the source code, it's no problem at all -- I
determine the source range and the line number, and I can set the
breakpoint just perfectly.
So, what can I do now?
I tried a JDIDebugModel.createMethodEntryBreakpoint(resource,
"java.io.FileReader", "FileReader", "(Ljava.lang.String;)V", 0, -1, -1,
0, true, attributes);
But that did not work (I also tried -1 as line number). Is it because
of the signature, or did I miss something else?
Thanks for your help,
Philipp Bouillon
