Response to: Problems
You will need to use the AOPAlliance jar file. http://sourceforge.net/projects/aopalliance Place this file into your web-inf/lib directory. You can also download Spring 1.0.2 with dependencies if you want to get the jar from that source as well.

Showing messages 1 through 2 of 2.

  I had same prob. and I had aopalliance.jar in web-inf/lib but I carelessy put a duplicate copy of spring.jar in tomcat/server/lib and I got a very similiar message you had. Remove duplicate, AOK.
