Test JVM

Hi,

Can anyone tell me if there is a utility I can use to tell whether the Sun JVM is working correctly on a machine not connected to the Internet ?

I have got an application which involves communication with a remote machine and need to figure out whether it is the JVM on the local machine that is not working or whether something is affecting communication from the remote machine.

Many thanks.

Define "not working".Can it run programs? Does it recieve communication at all? I would suggest you develop a simple test program and run it.

Unfortunately I am not a developer, I have to support this package which I do not have the source code for. As far as I can see the JVM is installed correctly (on Windows 2003) and I have also established that communication is possible between the 2 machines on the required port. However, I still get an error when I try to run it...

Error is "either you do not have a supported Java Virtual Machine installed or you did not accept the security credentials for the applet". I've checked that the JVM is at the recommended version, so its not that. However, the error is appearing before the certificate is received, so there is no opportunity to accept or reject it. Hence, I feel that either the JVM is not loading correctly or something is preventing transfer of the certificate. I'm just struggling to eliminate either possibility so I can focus on the other....
