Hi Sir,
I tried the example from below URL. http://developer.java.sun.com/developer/JDCTechTips/2001/tt0227.html#dynamic
I encounter the following error message when i run the client program.
Below is the error message.

C:\jdk1.3.1\Article_eg\test_2>java -cp Client \
-Dsun.rmi.loader.logLevel=VERBOSE \
-Djava.security.policy=Client/SimpleRMI.policy \
-Djava.security.manager EchoClient
Connecting to echo server...

Here is the content of the SimpleRMI.policy file.
grant {
permission java.net.SocketPermission" *:1024-", "accept, connect";
permission java.io.FilePermission "${/}c${/}jdk1.3.1${/}Article_eg${/}test_2${/}Client${/}-", "read";
};
I am new in RMI.
Can anyone of you please help me?
What's wrong ?
Thank you in advance.
