Re :[aspectj-users] Load-time weaving problem

["Kunal Pathak" <kunalpathak2006@xxxxxxxxxxxxxx>]

Hi Stefen,

Are you using the aj command to see the output? Have you created the aop.xml that is essential for weaving the aspects at load-time?

If you can describe the steps that you followed, it would be great for us to analyze the problem.

  Hi there,
  
  I can't get load-time weaving to work. Compile-time weaving however  
  works fine so I suppose the @ApsectJ annotations are all okay.
  
  I'm using AspectJ 1.5.4 and tried on Java 5 and 6 on Mac OS X 10.5.2  
  if that matters. I pass the following VM option to the java executable:
  
  	-javaagent:lib/aspectjweaver.jar
  
  The jar file is found by the JVM (changing the path/name causes an  
  error) but the aspects are not woven in.
  
  Any ideas? Did I miss something fundamental in the documentation?
  
  I also added the following options:
  
  	-Daj.weaving.verbose=true
  	-Dorg.aspectj.weaver.showWeaveInfo=true
  	-Dorg.aspectj.tracing.enabled=true
  	-Dorg.aspectj.tracing.factory=default
  	-Dorg.aspectj.tracing.file=aspectj-trace.log
  
  and found some suspicious output in the log:
  
  18:37:43.185 main > org.aspectj.weaver.loadtime.Aj.preProcess  
  org.aspectj.weaver.loadtime.Aj@375212bc audaarch/Service, byte[361],

  audaarch.Service is the Interface of the aspect's target.
  
  Thanks in advance,
    Stefan
