I will have to swallow my pride with this question. I bet this is a very easy issue, but for some reason I haven't found an answer. I moved my JARs from the .../tomcat/shared/lib directory to the web-inf/lib directory in the app itself, but it seems that the JARs there are not being discovered by

Solved: I had several contexts in my server, in each one was already a WAR created days ago. I forgot about all these old WARs. Since I took off my JARs from the shared/lib directory, all these old WARs could not work because they didn't include the JARs inside. So basically I was trying to run
