[George Harley1 <GHARLEY@xxxxxxxxxx>]

Hi Jens, 

I am using AJDT 3.0 RC2 with a development
build of AJDT 1.1.11 from out of CVS and cannot get a failure in the way
you describe using the trace aspect you included in your original note.
There is a change in AJDT 1.1.11 (due for release any day now) that should
make plug-in development somewhat easier (see bugzilla defect 62625 https://bugs.eclipse.org/bugs/show_bug.cgi?id=62625)
as it brings in the org.eclipse.ajde plug-in as a runtime dependency for
you automatically upon giving your project an AspectJ nature. 

Some more useful information might be
found if you examine one of the other entries in the Error View. I noticed
just a few minutes ago - in the middle of writing this response - that
if I inadvertently created a situation where the trace aspect tried to
advise itself (it's late here) and got into a loop, then a similar failure
to what you describe occurred. However it wasn't until I examined the Error
View entry for "An error occurred while automatically activating bundle
MyPlugin (91) " that I found any information about the java.lang.StackOverflowError
that was at the root. Is there a similar "root exception" that
perhaps you have not found yet ?

Best regards,
George

Subject	[aspectj-users] AspectJ/AJDT in Eclipse-Plugin-Projects - where's my mistake?

Hello, I am developing an Eclipse-Plugin and I want
to use AspectJ for 
some "aspects". There seems to be a problem doing this the simple
way. I 
tried the following (Latest Stable Eclipse 3.0.0/AJDT ):

1. Create a Plugin-Project using the wizard
2. Select the "Hello, World"-Template
2.1 Run (Runtime Workbench) => Works
3. Right-click on project and choose "Convert to AJDT Project"
3.1 Run => Works
4. Add a simple aspect to the main package, sth. like that:

package aj_hello_plug;


public aspect TraceAspect {

                  pointcut
staticCalls()
                  
               
: call(* Aj_hello_plugPlugin.*(..));

                  before()
: staticCalls() {
                  
               
System.out.println("Call to " + thisJoinPoint);
                  }
}

4.1 Run => Does not work (Error log see below)

What a I missing? I tried some more things like adding the rt-jar to 
classpath and so on but it just won't work. Any help is appreciated. It
would be very nice to have AspectJ at hand while developing plug-ins.

Regards,
Jens
