Hi,
I am trying to use an applet to connect to a database that resides on another computer.
The database server is not on the client computer where the applet is downloaded nor is it on the web server where the applet is located.
I have granted socket permission to the applet codebase and have added the policy file into the "master security properties file" (java.security file).
However when I try to access the page containing the applet using Internet Explorer, it still gives a java.security.AccessControlException.
The strange thing is, I am able to connect to the database using AppletViewer.
Can somebody tell me what's wrong with IE?
BTW, I am using a Java Plug-In 1.3.1.
Please help.

Look more closely at your security setup. The AppletViewer isn't as tightly confined to the "sandbox" as a browser is.
Venkat's right, though. Unless you're writing apps for an environment that's rigidly controlled, it's nothing but heartache to try and talk from a web client directly to a DBMS. Even if you get your applet signed and the security all cleared, someone else's firewall can block you.
