security_databases thread: Re: java.security.
> hello:
i have written an application that acesses oracle 9i database for some data
and then displays this data. this application works fine but my troubles
started when i tried to convert it in to an applet. so from the applet when
i try to acess the database, i get an error which says;
C:\brobbwork>appletViewer Vasxpro.html
response error problem loading oracle driver
access denied (java.lang.RuntimePermission exitVM)
java.security.AccessControlException: access denied
(java.lang.RuntimePermission

at java.lang.Thread.run(Unknown Source)
Generating 3D display....
java.lang.NullPointerException
so basically, it seems that the following code is not executing
correctly:
try
{
Class.forName("oracle.jdbc.driver.OracleDriver");
}
catch(ClassNotFoundException x)
{
System.out.println("response error roblem loading oracle driver");
System.exit(0);
}
for some reason it cannot load the driver and i will to glad to know any
work around this problem.
thanks for your time.
