I have an webstart app running on weblogic, my app uses some classes from the rt.jar. When I start my app from a client I get some ClassNotFoundException because it can't find classes from the rt.jar file. I have installed jdk1.4.2 on the client.
Is it not possible for my app to see the classes in the rt.jar ???

A possible explanation :
Does the attribute "version" of "j2se" element have a restricting version specified?
Say, if the client has JRE 1.2 and JRE 1.4.2 installed, and the version attribute's value is "1.2", the 1.2's rt.jar is used, instead of 1.4.2's.

My jnlp file says :
<j2se version="1.4.*"/>
and I have the j2sdk1.4.2 installed on the client.

I suspect that the version string is not valid. Can you check what error messages are logged to the console?
