Thread: Applet problem

Hi

I have some problem with my applet

in fact when i use jdbc for postgresql with a basic java program it perfectly
works.
when i try to connect from the server to the server it works. When i try from an
other computer to the server it works.
but when i try to use it from my applet, it says it cant load the drivers.I
tried from the server and from another computer , it both does'nt work.

for the sources, i use exemples from postgresql.org

if you have any solution, it will be great

thanks

The classpath of an applet is very restricted and specifically different
from standalone applications.

You have to bring the postgresql code into the classpath. The canonical way
would be to create one jar-file containing your applet and all needed classes
from postgresql.jar, but there are probly better ways I don't know of :-)

Well, it *should* work then. Are you sure that its not the class name
of the applet itself which is not being found? (In Mozilla you can look
at Tools->Web Development->Java console).

Apart from that, we need the full applet-element declaration from the
webpage, name of your browser, jdk version of your browser plugin, and
the exact error message (with stack trace).
