I'm running into this error trying to load the web UI for my Dell Equallogic. I've made sure I've updated to Java 7, have current versions of FireFox (27) and Chrome (30.0.1599.114) and experience this same error on both.
This is running under Ubuntu 12.04.3 LTS.
I've tried making the Java security settings as lax as possible as well as clearing it's cache.
I found this thread that describes many people with similar problems with no real solution.
Has anyone ran into this?
It has to be something with my specific computer settings since others are able to pull it up.
UPDATE
The exception now makes a little sense. I was able to pull up
http://eql/welcome.html
to launch it as a local java app.
Looking at the jnlp there's a resource definition
<jar href="http://eql/lib/equallogic-6.0.jar" download="eager" main="true"/>
Where "eql" is the correct hostname. That URL however 404s.

In the Java 7 security settings, you should ensure that the URL for Group Manager has been added to the "site list" for security exceptions. Also, if you're using v6.x firmware, you're likely to have better luck with Java 6 update 45. The Java applet was written for Java 6.
Alternatively, if you update firmware to v7.x then you shouldn't have any problems using Java 7 with the re-written Java interface.
