Spring error - very mysterious

[JohnSee]

i am creating a spring project with AOP features. I am getting this error. And the same thing created on somebody else's computer, there is no error

I have all the required jars and if i run the same thing in another computer, it runs fine.

ok if i change a line in context.xml as
<context:annotation-config/>
<!--aop:aspectj-autoproxy/-->
<aop:aspectj-autoproxy>
<aop:include name="aopTest"/>
</aop:aspectj-autoproxy>


<bean id="aopTest" name="alias1 alias2" class="spring.aop.AopTest"/>
<bean id="aspectBean" class="spring.aop.BeforeExample"/>

it then compiles successfully but none of the advice are executed

Maybe on the other computer there's some slight classpath difference.
The problem seems to come from asm.jar. Either this jar is not there or its version is incompatible with your cglib.jar
If possible, I recommend to use cglib_nodep.jar as this already includes asm.

Also check out other components in your application which use cglib (e.g. hibernate). If these also add their jars to the classpath and use a different version then order matters.

Andreas
