Re: [aspectj-users] Load Time Weaving in Eclipse

Perhaps the clue I overlooked was here:

Eclipse)

If you can't make it work inside Eclipse then there must be a problem with the launch configuration.  When I define a launch configuration for loadtime weaving, I specify the javaagent setting in the VM arguments box, and then I setup the classpath on the classpath panel, I do not specify -classpath in the VM arguments section.  Where are you setting the classpath?

Dear Andy,

I used your documentation to test it initially (indeed it is very well explained).

 

I tried to add -verbose and -showWeaveInfo to the .xml (both in the aspect jar and the Java project web-inf). I also changed src classpath directions to bin.

Nothing changed and nothing extra showed in the console.

 

I am not using Load-time weaving application launch configuration (answering to Andrew) because my goal is to use this with Midlets and I think this option would not be compatible to them.

 

What else can I try?

 

Thanks  a lot for your comments. I am looking forward to new suggestions.

Hi,

-javaagent:C:\aspectj1.6\lib\

aspectjweaver.jar -classpath "PATHTOJAVAPROJECT\src;  PATHTOASPECTPROJECT\AspectName.jar; C:\aspectj1.6\lib\aspectjweaver.jar"

 
shouldn't that say 'PATHTOJAVAPROJECT\bin' rather than PATHTOJAVAPROJECT\src?

add an extra aop.xml file to your java project, put it in  META-INF\aop.xml and turn on debugging for the weaver.  The options for what to put in there to turn on debugging are discussed here:

http://andrewclement.blogspot.com/2009/02/load-time-weaving-basics.html

that will tell you whether it is a problem even creating the weaver, or with the aspects.

Hi all,

I am trying to test Load TIme Weaving with the AJDT Eclipse plugin. (I could make it work out of Eclipse and I could make normal weaving in Eclipse)

What I have is

1) a Java Project with a Java application

2) an AspectJ Project which has an aspect which would intercept a method execution in the Java application.

3) An aop.xml file defining the available aspects in the AspectJ Project and in a WEB-INF directory in the Java project .

 

The aspect has been weaved with ajc AspectName.java -outxml -outjar aspectName.jar

In the Java Project VM arguments I have added -javaagent:C:\aspectj1.6\lib\aspectjweaver.jar -classpath "PATHTOJAVAPROJECT\src;  PATHTOASPECTPROJECT\AspectName.jar; C:\aspectj1.6\lib\aspectjweaver.jar"

 

The project runs properly but the aspect is not taken into account.

 

Any help is welcomed,

thanks a lot,

Guadalupe
