Hi, I'm trying to run the Sing Li Spring tutorial, and when running the app in tomcat 5.5.23 I get the following exception:

I'm using Spring 2.0.6

Any ideas what might be wrong?.

I put the spring jar's inside common/lib folder of tomcat, inside WebContent/WEB-INF/lib, added to build-path, run-path of the eclipse project, and still getting the same erro.

Thanks.

Seeing as there's nothing related to Spring in that stack trace, it looks like an environment / install issue.

1> Does the problem go away when you remove all Spring-related jars?
2> Is it possible your CATALINA_HOME is pointing to a different directory than the one you're running Tomcat from (version mismatch)?

I put the spring jar's inside common/lib folder of tomcat, inside WebContent/WEB-INF/lib

why you copy the jars in the common/lib ???

is enough in your appname/WEB-INF/lib

if you can use the tomcat plugin for eclipse, use it, its nice
