I'm trying to deploy my recently coded "HelloWorld" application to
Tomcat.
I used the build scripts to generate the war file.
When i deploy to Tomcat the application gets loaded properly.
The problem arises when i access the application.
In one of my ServiceImpls i have somehow got a runtime dependency on
org.apache.commons.logging.LogFactory which is present in "gwt-
dev.jar"
SEVERE: Exception while dispatching incoming RPC call
com.google.gwt.user.server.rpc.UnexpectedException: Service method
'public abstract void
com.company.module.client.user.UserService.authenticateUser(com.company.module.shared.UserDTO)
throws com.company.module.shared.MpfException' threw an unexpected
exception: java.lang.NoClassDefFoundError: org/apache/commons/logging/
LogFactory

com.google.gwt.user.server.rpc.RemoteServiceServlet.processCall(RemoteServiceServlet.java:

To solve this problem i added the gwt-dev.jar & gwt-user.jar from the
SDK to the war/WEB-INF/lib folder,
then these jars are not loaded because of the error,

validateJarFile

Did anyone get a similar error? and if yes how did you guys get around
to fix it?
