[aspectj-users] LTW exceptions

I have a very simple (HelloWorld) servlet with an aspect that I am trying to use with load-time weaving under Tomcat.

My aop.xml:

<aspectj>         

   <aspects>

        <aspect name="HttpServletMonitor"/>                  

   </aspects>

    <weaver options="-verbose -XlazyTjp">

        <include within="com.company.HWServlet"/>

   </weaver>

</aspectj>

public aspect HttpServletMonitor {

              public pointcut monitoredOperation(Object operation) :

                execution(void HttpServlet.doGet(HttpServletRequest , HttpServletResponse )) && this(operation);

              void around(Object operation) : monitoredOperation(operation) {

                  proceed(operation);

                  // write a tag to file.

              }

             

              public HttpServletMonitor(){

              }

}

 

I have the hwmonitor.jar, aop.xml, aspectj.jar and aspectjweaver.jar in my classpath, and defined javaagent

 

When I run this, I can see the loader trying to weave, but it’s trying to weave everything it comes across instead of just HWServlet!

 

 I end up with lots of exceptions of the following. Any thoughts on what I’ve done to cause these?

If I change the execution line to look for HWServlet.doGet() I get lots of a different exception:
