Error initializing the application with Spring Security: net/sf/ehcache/Ehcache not found

Question

I want to use the Spring Security ACL plugin with mongodb.

When I run my app I get the following error:

How should I run this?

Answer 1

You are missing the ehcache.jar in your setup, or there are several of them, causing the version conflict.

You can find the latest ehcache.jar on the Maven repository
