Hi everyone,

I am trying to use parallel computing toolbox (2014b version), but I couldn't organize manage cluster profile (all updates for java is working properly). When I click manage cluster profile, I get the following error in command window and I couldn't click any button (such as add, discover cluster or import) in cluster manager window.

In onether words, I couldn't use parallel computing toolbox in order to connect any cluster. I would greatly appreciate it if someone help me. Regards.

manage cluster profile inrunning jobs through the parallel computing toolbox and from time to time I receive java errors. For example, when I use the parcluster command, the following error comes up:
