This is a feature of the Applet security model - it's nothing you're doing.
An applet may only open a socket to speak with the machine it was downloaded
from. If a client downloads the applet from a server at IP address
111.22.333.44, the applet can open a socket connection to 111.22.333.44 but
NOWHERE ELSE. Anything you want to contact DIRECTLY via a socket from your
applet MUST reside on 111.22.333.44 (the <client:ip> you mentioned below).

> Hi,

> My applet that access database is working if the database and

> The same is not working if the two reside in different machines, gives
> Applet Security exception.. If I run the applet on Appletviewer, it

> My doubt is in the error message received.
> "Could not connect to <database:IP> with origin from <web server:IP>
> The applet is in a jar file with the Oracle Driver. Is this a

> Since, the applet is fully equiped with the driver, on

> "Could not connect to <database:IP> with origin from <client:IP>
> In contrast to my understanding, does the request to Databse
