With the latest Java updates the security settings has been set at a higher level by default and there are many websites that now experience problems with some older Java applets that no longer works. This is a common informational dialog box that is shown lately.
If Java is a requirement for your Linux/Windows workstation, perhaps if you are using the console feature in SolusVM, consider adjusting the java security level for best security/functionality.
Let me show you how it is done!
In Linux: From the terminal, run the command jcontrol (should mention that you need a desktop GUI for this)
In Windows: Double-click the Java icon in the control panel.
This will launch the Java Control Panel. In this Control Panel various security settings can be made as well as an option to disable java completely in the browser. This Control Panel looks the same in Windows and Linux.
Go to the Security tab and click on the Edit Site List button, in the next dialog, enter the base url to the site that you want to add as an exception to the security level and click OK.
Click OK until all dialog boxes are closed. Restart your browser and reload the website that you were blocked from before.
If you have completed all steps the java applet will work without problems.
