How to run Applet with Ms Sql connectivity in browser

[mayanksmart4]

I have made MS SQL connectivity in APPLET code using JFRAME. When i'm running it in NETBEANS IDE, the program is running successfully, data from the DB is shown on the JFRAME. The problem arises when i'm ruuning that applet in my browser only the JFRAME is shown, data from the DB is not shown. I have placed the MS-SQL Drivers in the same directory where the applet code is.
I don't know why it is happening.
Please suggest some solution of this problem.

Are there any error messages in the browser's java console?

As such there are no error messages..

Try debugging the applet by adding some println statements to show where the program is executing.
The print outs will be in the java console.

Check all your catch blocks and make sure that they call printStackTrace()

NoClassDefFoundError: com/microsoft/jdbc/base/BaseDriver

where is the definition for class named in the error message?
You probably need to add a jar file that contains that class's definition to the archive= attribute

[mayanksmart4]

how to do so??
Dont know how to provice class definitions, please help me. describe in detail , if possible..

[Norm]

Sorry, I have no idea where your missing class definition is.
You need to find an HTML reference manual to get the correct coding syntax for your HTML.

Somehow I have managed to solve some exceptions at run time, but I am still getting dese errors

access denied (java.lang.RuntimePermission exitVM.0)

Applets are not allowed to call System.exit(0);
