Java Web Start, JAAS and DB authentication problem

Thread view:

Hi all,

I'm using JAAS to do user authentication. My login module does a DB access
to that purpose.

Unfortunately, when starting my application with Java Web Start, i get a
NoClassDefFoundError on the DB driver class, although i added the driver's
jar to my JNLP file.

I read somewhere, that older versions of JWS were using an other class
loader for loading JAAS's login modules (and not the context class loader),
so i thought this might be my problem... so i downloaded and installed JDK
1.4.2_01 but that still doesn't help...

Any suggestion ?

Thanks in advance.

I have a similar problem. I have found that going into Java Webstart and
enabling the console log
eliminates the problem. This problem only occurs (for me) when using the
IBM JRE. If I use the JRE
from the Sun (JRE V1.4.2) the problem goes away. You might try enabling the
java console log to see
if you have the same problem.
