Re: [aspectj-dev] Load-time weaving with Eclipse RCP application 
Thanks for testing but I don't think that the problem is solved.
I suppose you didn't mail the whole output. I get this too, but as soon as the launcher starts the EclipseStarter, it seems that no more matching joinpoints will be found. The last output I get is 

before: call(Class java.net.URLClassLoader.loadClass(String))
arg0(class java.lang.String)= org.eclipse.core.runtime.adaptor.EclipseStarter 
WeavingAdaptor.weaveClass org/eclipse/core/runtime/adaptor/EclipseStarter
before: call(Class java.lang.Class.forName(String))
arg0(class java.lang.String)= [Ljava.lang.String;
before: call(Class java.lang.Class.forName(String))
arg0(class java.lang.String)= java.lang.Runnable

At least the call of the method start method of RCPDEMO should be announced.
I'm interested in information that my aspect gets from my own classes in the package rcpdemo. But if I edit the aop.xml and set <include within="rcpdemo.*"/> I get no aspect output.

Thanks Stephan for sending me the demo app.

I started it using the current AspectJ build aspectjweaver.jar (I
don't know which one you are using, but I haven't done any specific
fix for this to work recently)  and java5, with:

set MCLASSPATH=loglib.jar;startup.jar;.

java -javaagent:%AJH%\aspectjweaver.jar -cp %MCLASSPATH%
org.eclipse.core.launcher.Main


and I get :
(just add -verbose -showWeaveInfo in the weaver option in aop.xml)

arg0(class java.lang.String)= osgi.configuration.area
before: call(String java.lang.System.getProperty(String))
arg0(class java.lang.String)= osgi.baseConfiguration.area
before: call(String java.lang.System.getProperty(String))
arg0(class java.lang.String)= osgi.install.area
before: call(Class java.lang.Class.forName(String))
arg0(class java.lang.String)= org.eclipse.core.launcher.Main
before: call(String org.eclipse.core.launcher.Main.decode(String))
arg0(class java.lang.String)= /C:/Documents%20and%20Settings/avasseur/Bureau/RCP
demo/RCPDEMO1/eclipse/startup.jar
before: call(Class java.lang.Class.forName(String))
arg0(class java.lang.String)= java.net.URLDecoder
before: call(Class java.lang.Class.forName(String))
arg0(class java.lang.String)= java.lang.String
before: call(int java.lang.String.indexOf(int))
arg0(class java.lang.Integer)= 43
before: call(char java.lang.String.charAt(int))
arg0(class java.lang.Integer)= 0
before: call(boolean java.lang.Character.isUpperCase(char))
arg0(class java.lang.Character)= C
before: call(char java.lang.Character.toLowerCase(char))

I can't get it to run with rcpdemo.exe and -vmargs though - don't know
what's going on there (keeps failing complaining that the aspect from
aop.xml cannot be found ie is not in the classpath)

Hello,

The exact command line is

    java -javaagent:%ASPECTJ_HOME%\lib\aspectjweaver.jar
         org.eclipse.core.launcher.Main

I use it from my product's directory which contains the META-INF
directory with aop.xml

ASPECTJ_HOME=C:\Programme\_develop\AspectJ
CLASSPATH=C:\temp\RCPDEMO\eclipse\loglib.jar;
    C:\temp\RCPDEMO\eclipse\startup.jar;
    C:\Programme\_develop\AspectJ\lib\aspectjrt.jar;.

loglib.jar contains my aspect and startup.jar contains the class which I
start from the command line.

I also tried to start the product's exe with

    rcpdemo -consolelog
        -vmargs -javaagent:%ASPECTJ_HOME%\lib\aspectjweaver.jar

but even with <include within="*"/> I didn't get any output from the apsect.

Thanks, Stephan

Hi

Can you send me the exact command line you are using asuming f.e. you
have ASPECTJ_HOME and ECLIPSE_HOME set ?

I am not familiar with that but I would assume you need to use -vmargs
Eclipse option and sort of.
Thanks

Hello,

I posted this problem to eclipse.technology.aspectj and I was suggested
to post
it here:

I want to use load-time weaving with an Eclipse RCP Application and
the -javaagent:aspectweaver.jar option but it doesn'nt work as it should.

I start the application with

java -javaagent:%ASPECTJ_HOME%\lib\aspectweaver.jar
 org.eclipse.core.launcher.Main

My aop.xml looks like this:

<aspectj>
<aspects>
  <aspect name="util.logging.LoggingAspect"/>
</aspects>
<weaver options=" -nowarn">
  <include within="rcpdemo.*"/>
</weaver>
</aspectj>


My aspect generates an output before any method call. This works fine for
simple java applications but not for RCP applications. Allthough I get a
lot
of messages that classes are going to be woven (e. g.
WeavingAdaptor.weaveClass org/eclipse/ui/internal/PerspectiveHelper) the
desired output from the aspect does not appear.

When I change the 'include within' attribute of aop.xml to "*" I get the
same WeavingAdaptor messages and additional output from my aspect. But the
aspect does not create output from method calls within any plugin. The
output appears only for method calls within the eclipse launcher in the
startup.jar.

I know about the AJEER plugin but it works only with the AJDT 1.1.12 which
are available for Eclipse 3.0. But is there any possibility to use
load-time
weaving with RCP applications developed with Eclipse 3.1 and upcoming
versions?

Regards, Stephan
