Java EE (Java Enterprise Edition) General Discussion

We have a portal page that uses a mail module to silently authenticate users with our LDAP server. This mail server is not MS Exchange server. Basically, the module has a link that brings up the mail information within the portal page. This is identical as someone accessing the mail server directly from outside the portal. I'm enhancing this code (jsp) to read the mail from MS Exchange 2003 server, but it gives me an error.

Here it is:
access denied (java.net.SocketPermission ourExchangeServerURL resolve)

If someone would help me with hints/sample codes/pointing to a technical documents/anything, I'll greatly appreciate.

Thank you,
