Aspect on JSP

[aline_mm]

Hi, I want to now how can I apply a Aspect on JSP.

I read some papers, and I now that a JSP is like a Servlet... if can I apply a Aspect on a Servlet it is true with a JSP???

If it's is true, someone have a example with JSP???

Tnks' Aline.

It is not possible to use the AopC compiler as you don't have the .class files in this moment, so the only possible alternative is to enable the EnableTransformer flag on \conf\jboss-service.xml.
Have you tried?

In spite of this, I'm not sure the container that create the jsp servlet is under the wings of the AspectManagerService.

I don't think JSP aspectizing will work as it uses a different classloader. We will be improving our classloader integration shortly.

Can you verify JSPs don't work?

I do think it will work if you precompile your jsps.

Thanks and apologies.

Hi Bill,

I tried to use, jspc (created a *.java and a *.class) and aopc, the deploy was ok but when I called my page I received this error.

Do you have any idea about this?

Can you send me a mini testcase? It would speed things up for us to fix.
