FW: NoSuchMethodError: aspectOf()

Any ideas why I am get the NoSuchMethodError below?

The method specified by the pointcut is in com.foo.action.LoginAction.execute.

The aspect is defined in com.foo.logging.Login.   (see below)

My code which is being advised does not call the aspect’s aspectOf() method.

I use build-time bytecode weaving using the ant <iajc> task.

The app is a Struts-based web app.

javax.servlet.ServletException: Servlet execution threw an exception

Hi Andy,

Thank you very much for looking at my problem.

Yes I included the aspect in my call to iajc.

Below is a portion of my build.xml (target Pdm.war) and the output of “ant Pdm.war”.

Login.java is my aspect expressed in @AspectJ notation.

Hi Roger,

Are you definetly including the aspect itself in the call to iajc?

Annotation style aspects (when @Pointcut/etc are used) can be compiled

with javac, but they must be given to the weaver at some point in

order for the missing methods to be added - for example 'aspectOf()'.

cheers,

Andy
