I am new to RIM, and currently taking the tutorial at http:\/\/java.sun.com\/docs\/books\/tutorial\/rmi\/overview.html<\/p>\n

I am able to start server like:<\/p>\n

However, when i try to run client i got exceptions<\/p>\n

i believe the problem is the client policy file for client (correct if i am wrong please), as we can see from stack trace<\/p>\n
\nCaused by: java.security.AccessControlException: access denied (java.io.FilePerm\nission \\c:\\home\\jones\\public_html\\classes\\- read)\n<\/pre>\n
However, my client.policy file looks like<\/p>\n
\ngrant codeBase \"file:\/c:\/home\/jones\/public_html\/classes\/-\" {\n    permission java.security.AllPermission;\n };\ngrant{\n    permission java.net.SocketPermission \"127.0.0.1:1024-65535\", \"connect,resolve\";\n};\n<\/pre>\n
There are AllPermission for codeBase “file:\/c:\/home\/jones\/public_html\/classes\/-“.<\/p>\n
So, did i set the codeBase permission wrong, so there are more permission client application needs?<\/p>\n
Thanks!!!<\/p>\n
Update: if i move the client.policy file to C:\\Program Files\\Java\\jre6\\lib\\security and i start the client with<\/p>\n
