out of ideas on an error

[Kevin Fonner]

I am attempting to set up a servlet which acts as and rmi client.  I am getting an error which I don't understand.  Are their additional securitys I have to set or something?? Here's the error   Internal Servlet Error: java.lang.NullPointerException at java.lang.ClassLoader.resolveClass0(Native Method) at java.lang.ClassLoader.resolveClass(ClassLoader.java:588) at org.apache.tomcat.loader.AdaptiveClassLoader.loadClass(AdaptiveClassLoader.java:518) at org.apache.tomcat.loader.AdaptiveServletLoader.loadClass(AdaptiveServletLoader.java:174) at org.apache.tomcat.core.ServletWrapper.loadServlet(ServletWrapper.java:265) at org.apache.tomcat.core.ServletWrapper.init(ServletWrapper.java:289) at org.apache.tomcat.core.Handler.service(Handler.java:254) at org.apache.tomcat.core.ServletWrapper.service(ServletWrapper.java:372) at org.apache.tomcat.core.ContextManager.internalService(ContextManager.java:797) at org.apache.tomcat.core.ContextManager.service(ContextManager.java:743) at org.apache.tomcat.service.http.HttpConnectionHandler.processConnection(HttpConnectionHandler.java:210) at org.apache.tomcat.service.TcpWorkerThread.runIt(PoolTcpEndpoint.java:416) at org.apache.tomcat.util.ThreadPool$ControlRunnable.run(ThreadPool.java:498) at java.lang.Thread.run(Thread.java:484)
