hi,all
   I am new to ejb development. I have successfully deployed a helloworld ejb component on Jrun server, then I started running the ejb client to invoke the ejb method. But there are always errors.
   When running the ejb client class on the local machine as follows:
   java -Djava.security.policy=java.policy example1.HelloWorldClient
   
   I got an exception of java.lang.NoClassDefFoundError: example1/HelloWorldClient. In the client class source code, the initialcontextfactory and providerurl properties are set to jrun.naming.JRunContextFactory and localhost:2918.

   When running the ejb client class from a remote host as
above, I got another exception of java.lang.ClassNotFoundException: jrun.naming.JRunContextFactory.But the providerurl property has changed to 168.192.0.3:2918 which is the url of the Jrun server.

   I really don't what hell is going on, please give me some hint.

you need to setup your classpath to include the helloworld class

the full path to the jar file is also set in the classpath of the jrun server
host, but the problem still exists.
To solve the exception of running the client from remote host, could you give
some help?
