no suitable driver i browser - but works fine in appletviewer

Hi,

I have a problem when I open a htm file with netscape containing a
applet against postgresql.

I get the error  "no suitable driver".

The jdbc7.0-1.2.jar file is in the same library as the class and the htm
file.

Using appletviewer everything works just fine.

Here is the a part of the htm file.

<applet
code=ins.class  archive=jdbc7.0-1.2.jar
</applet

I'm using RH7.1  workstation.

Can anyone help?

TIA

Poul
