Thanks Dave, your advice is very helpful.

I solved the problem by putting the aspecjrt.jar file intoTomcat_directory\shared\lib. Now my aspect works fine.

Hi Lily, I had a similar problem working with Tomcat. Reading the dump you
provided you can read :

root cause
>
> java.lang.NoClassDefFoundError: org/aspectj/lang/NoAspectBoundException

It seems that some classes are not present in the classpath and the
classloader can't find them.

I Resolved it including aspectjrt.jar included in aspectjx.x/lib directoryin

your Tomcat's classpath.

For doing this simply include in the executable file catalina.sh a linelike

this:
CLASSPATH=$CLASSPATH:./aspectj_direcory/lib/aspectjrt.jar (Linux like env,
vars on Windows is a little bit different)

I hope this solves the problem.
