I've downloaded eclipse for ubuntu and I configure it with Tomcat 7 and I'm running eclipse with JDK 7.

When I start the server from the Servers tab, I get this exception:

java.lang.NoClassDefFoundError: org/apache/tomcat/util/digester/Rule

How can I solve this problem ?

Just check whether you are trying to start Apache more than once i.e. through cmd and/or eclipse(some IDE)
