Classloading problem with servlet on Tomcat.

[John Eric Hamacher]

Hello:

I am trying to deploy a webapp to Tomcat 6 from within Eclipse 3.4 and get the following message on the console:

SEVERE: Error loading WebappClassLoader
  delegate: false
  repositories:
    /WEB-INF/classes/
----------> Parent Classloader:
org.apache.catalina.loader.StandardClassLoader@1abab88
 com.gallup.ice.screen28.server.rpc.firstletter.FirstLetterServiceImpl
java.lang.ClassNotFoundException: com.gallup.ice.screen28.server.rpc.firstletter.FirstLetterServiceImpl

	at java.lang.Thread.run(Thread.java:595)  

The class in question, com.gallup.ice.screen28.server.rpc.firstletter.FirstLetterServiceImpl, is located in a jar wthin the project. I'm a little ignorant on the subject of classloading. Can somebody tell me what this means and how I can avoid this? Just to note, this servlet is being called from Javascript (this is a GWT application).

Thanks
Eric
