------ Solution ------------------------------------ --------
should be even less a aopalliance.jar
------ Solution --------------------- -----------------------
added yet determined to tomcat webapps next look at whether this package and then consider the next packet collisions is not it
------ Solution ----------------------------- ---------------
you add the finished package , added to the compiler environment yet ? If you add , that you try to delete a look at this package should be package conflict
------ Solution ------------------- -------------------------
to see if the cause of the conflict is the package ;
spring alt2.7
struts asm2.2.3

say this two pack removal
------ For reference only ---------------------------- -----------
aopalliance.jar I also added still the same error
org / aopalliance / intercept / MethodInterceptor this class can be found in spring.jar
Is not there is a conflict between the jar package ?

------ For reference only ---------------------------------- -----
what you use development tools
------ For reference only ------------------------ ---------------
I use myeclipse9, intended to use another version of the jar try again !
