Error when deploying app to Tomcat

[tan]

Hi,

I got such error:

Can anyone tell me how to solve this problem? I found that there may be something wrong with ContextLoaderListener.

You have both ContextLoaderServlet and ContextLoaderListener in the web.xml. They do the same thing - load the app context, and only one is needed. If you are using a Servlet 2.4 container, use ContextLoaderListener, otherwise use ContextLoaderServlet.

I removed ContextLoaderListener and now I got:

Sorry for the previous post - I pressed <Enter> too fast.

So I got such error now:

How to solve this problem?

[tan]

OK, I found the problem by myself - it was mainly caused by a stupid mistake - forgot to copy some jar.files to Tomcat. Sometimes happens.
