Re: [aspectj-dev] Load-time weaving with Eclipse RCP application

[Alexandre Vasseur <avasseur@xxxxxxxxx>]

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)
