Error while launching Oracle VM Manager VNC Console
Issues -
Issue 1 - The launch console button downloaded a JNLP file but when we tried to open it gave a certificate error. Since the error stack is big, we have pasted its details at the end of this blog.
Issue 2 - When we fixed the certificate error it gave following error when we tried to open the downloaded JNLP file:
java.lang.SecurityException: Missing required Permissions manifest attribute in main jar: https://vmmgr327.aclnz.com:7002/ovm/rasproxy/ovm_rasproxy-signed.jar

Environment
- Oracle VM Server 3.2.7 (x86-64)
- Oracle VM Manager 3.2.7 (x86-64)
- Browser Firefox
- Java 7 Update 51
Investigation Done
For Issue 1 - The downloaded JNLP wasn't associated with any programs in Mozilla Firefox. It must be associated with Java in the client from which you want to view VNC Viewer for your VM.
For Issue 2 - it appears to be a compatibility issue with Java 7 update 51. Either download to a lower version of Java or reduce the security settings.
Resolution
Issue 1 Resolution - Simply go to Firefox > Options > Look for JNLP File > In the Actions drop down list, change it to 'Use Java(TM) Web Start Launcher'. Now relaunch the downloaded JNLP file and the certificate error will go off. But now you will get the above error 2.
Issue 2 Resolution - Go to Control Panel > Programs > Java > Security > Change to slider to make 'Medium' security. Now relaunch the JNLP file and you will be able to see the VNC Console on which your VM will be seen running.
