or, other messages might appear that reference the file java40.jar.
One reason for this error is having the CLASSPATH environment variable set. From Netscape's website :
If you set the CLASSPATH variable, you have to specify every .jar file that is included with Communicator explicitly. Communicator will not search directories; you must specify the individual files. You will also need to make sure you specify the Communicator java40.jar file before any directories that might contain a different java40.jar since Communicator stops searching as soon as it finds the first java40.jar.
Therefore, the recommended solution is to simply remove the CLASSPATH variable from your environment, at least temporarily, and re-run the setup.
When first loading Netscape make note of any errors in loading plug-ins. In one case, a plug-in was not able to be loaded and subsequently Java was not functional.
A current workaround is to take this errant plug-in and move it from the above directory. In effect, this plug-in will not be called.
Run install again.
If the previous solutions do not apply, it is suggested to download a stand-alone installer application. This download simply extracts the files off the original CD. For further information, please see (Xilinx Solution 8214).
