Setting Class path in Tomcat7 to solve NoClassDefNotFound error

I recently deployed a web app that I built in eclipse to an AWS ec2 instance. Worked fine in eclipse but got a NoClassDefNotFound error on my server. I wrote a test main method in my servlet and was able to get rid of the error by running 

java -cp .:(class paths to all imported classes). packageName.myservlet

So my question is how do I configure tomcat7 to include the class paths I did to get my servlet running properly, thanks.

Here some suspicious warning I found in catalina.out, and below is what I can use to get the servlet to run my test main method.

java -classpath .:/usr/lib/jvm/jre/lib/j2ee.jar:/usr/share/tomcat7/webapps/ArtGallery/WEB-INF/lib/* ArtworkServlet/ArtworkDB

Looking at the log file it seems there is an issue with Your tomcat installation. see the commenta For more info.

as brute Force Solution I suggest to reinstall tomcat.

working with the classpath is not the right way to solve the problem
