PI JAVA Hanging

So in trying to investigate a PI issue, I discovered that the client was running pure Java stack. I've not spent loads of time there, but was sure I could pick it up once I was in the correct transactions : Going to

NWA/Configuration just left me with the spinny-circle-of-boringness... PI was hanging.

An OSS Note (I forget which) said that JAVA PI systems hanging can be fixed by making a setting in Configuration... WTF? I can't even reach that, because the system is hanging! Maybe I got the wrong note.

In the end, this was fixed by:

Installing the newer version of Java
https://java.com/en/download/

Adding the URL of the application to the exceptions list:
http://neo.jpl.nasa.gov/orbits/java_exception.html

Also, in the place where you can set the exceptions, ramping the security down to minimum.


And now I can do all my PI config!

I'm looking forward to the next time I run eclipse, and seeing what the problems with that are!

This is one of the usual complaints about Java, there's a whole bunch of incompatibilities that mean you can only really purpose Java for one thing at a time! That and that SAP/Eclipse/IE never seem to keep up with what Java is doing...
