Unfortunately, unless you can get the postgresql.jar file into the
browser's internal class path (which is probably unlikely), it has to be
downloaded with the applet. This is a problem with JDBC in general (not
There are ways around this, like using a servlet on the web server. Your
applet talks to it, and it then uses JDBC. You could use RMI or your own
protocol to do this.
Another method is to strip postgresql.jar of all but the critical
classes you need. Most of the time you don't need everything in there
(like the largeobject & fastpath api's). This is tricky, but it can and
has been done. (hint: Run appletviewer with class loading tracing
enabled in the vm, and note which classes are loaded).

<applet code="gijdbc.class" width=630 height=400
But that means, that every body must download the postgresql.jar file
the .class file. And it is 130kbs :-O
Is there any way to integrate the postgresql.jar into the .class or
Thank you very much.
