PRB: Cannot Use JDBC in Applets Outside of Visual J++'s IDE

SYMPTOMS

When programming an Applet that uses JDBC, everything works in the
development environment. When the Applet is run outside of the development
environment, the Applet throws a com.ms.security.SecurityExceptionEx.

CAUSE

JDBC requires access to resources that are available only when outside the
set of security restrictions placed on non-trusted Java Applets, also known
as the "sandbox." Regular Applets cannot access files on the client's hard
drive, access other network sockets, or print. JDBC requires file
input/output. When trying to access a file on the client, the
SecurityExceptionEx is thrown.

RESOLUTION

In order for the Applet to work properly, you will need to create a cabinet
file and digitally sign it (see references for more information). Then you
need to add certain method calls in the Applet to "assert permissions"
(please see article reference below) for file input/output.

STATUS

This behavior is by design.
