Ubuntu - saying your security settings have blocked an application from running with an out-of-date version of java

Question

I have this new problem since 2014 begin. I cant remotely login to this enterprise network for giving them support. Its keep showing this new error.

How to fix it please?

EDIT:

Answer 1

Since the last Update to jdk 7u51, in the default settings of java (High) is not allowing to run java untrusted apps. I could remember to run some apps with same high security some days ago but now those are getting blocked. Only applets having a certificate and proper permissions attribute can be run.

How to run apps without certificate

• Update your jdk, latest is available here.
• [Never recommend, Do only if you trust the app] Open Java Control Panel by running javaws -viewer, Keep your security settings to Medium, it will allow all applications to run except applications that request all permissions. So it is vulnerable, should you run a malicious application^[source]
