# jar file: C: Program
files\netscape\communicator\program\java\classes\ifc11.jar
Path: idem "
I have a second message with java40.jar and a third message " Java
lang.Security Exception: system classes were not signed.
I am using the program Java Plug-in panel to control.

That means that I am unable to use Java programs even to download smart
updating within Netscape. There are web pages that I am unable to load.

I have tried to modify parameters of Internet Explorateur and netscape
but uncessfully.

Could you let me know how to solve this problem. Is it a problem of
unsigned certificate or parameters ? In the Plug in Control panel it not
appear any certificates.

Thanks in advance. Best Regards. JC COLLART
