Hi...
I resolved this problem in the java configuration

try

 

A.- Start --> Control panel --> Java

B.- In the "Java Control Panel" --> "Security" tab and choose "medium"

C.- Clic "OK" and restart browser.

Re: DL120 G6 LO100 Virtual KVM/Media Error Application Error Security Exception

The "Missing required Permissions manifest attribute..." error is caused by new security features in JRE 1.7.0_51.

 

RobertoMT's solution will work, but a more fine-grained solution is to put the LO100 URL into the "Exception Site List" in the Security page of the Java Control Panel.

 

In other words, if the main jar URL is http://192.168.xx.xx/M2.JAR:

  1. Start -> Control Panel -> Java
  2. in Java Control Panel, open the Security tab and click on "Edit Site List..."
  3. Click Add, then type in "http://192.168.x.x" without the quotes.

This will do the same as setting the security slider to Medium, but for the listed URL(s) only, so you can keep your Java security at the recommended level for everything else.

Perfect... that's fixed it allowing me to launch the KVM screen on my iLO 100 in my HP ML150 G6
