Re: JAVA errors when launching GUI

I've applied this patch and I still get the handshake error.  Any further advice?  Please see attached image for exact error.  CMU is 7.3.2.  Windows Java client is 1_79.  Java client works without issue on another CMU 7.3.2 deployed installation.

Re: JAVA errors when launching GUI

Hi,

As per the patch install instructions, have you restarted the CMU service after applying the patch ?
If not please restart the CMU service "/etc/init.d/cmu restart" and then retry launching the GUI.

Also please clear the browser and java cache on client machine before launching the GUI.
To clear java cache on windows:
    Control panel→java→General Tab→Temporary internet files→Settings→Delete files

Please let us know if this doesn't solve youre issue.

Thanks for your post Alok_Pandey. 

Even after clearing the Java cache, i still face the same issue. Not sure what is going on here.

Any help is much appreciated.
