ClassNotFoundException in Tomcat console when using jawr

I am using Tomcat from Eclipse. When i try to start the server I am getting the following error in the console:

java.lang.ClassNotFoundException: net.jawr.web.servlet.JawrServlet at org.a开发者_开发百科pache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1516)

When i deploy the war file in the Tomcat server outside of eclipse it is not having any problems. I am only getting this problem when i am trying to start tomcat from eclipse with jawr. Please let me know the solution for this problem.

Thanks in advance, Jaya

Is it possible that your jawr jar is not in your build path?

i.e. in plain Tomcat it's being loaded automatically from /WEB-INF/lib/, whereas Eclipse may be expecting it to be explicitly mapped.

Eclipse may be expecting it to be specifically added to the Build Path (in the Package Explorer, right-click on the Jar and "Add to build path", or on the project, right click Build Path > configure build path)

I think it's something like that. Hard to say for sure without more details ...
