Ok I have another problem that I'm simply not well versed enough to sort out.  When I run the Protégé Server on my personal machine - which has direct connection to the internet via local ISP, it starts up just fine,  BUT users inside of my Corpnet can only see it.  When they try to load a project they end up essentially timing out while waiting for the project to load.  They show up as a session connection, they just never get a loaded project.

Otoh if I connect via Localhost, I get connected just fine



So I hosted the Protégé server on a BehindThe Firewall VM based Windows server.  Everything installed as expected.  Protégé runs fine in local mode against the database and the metaProject.  Except when I go to load the server  I get a normal startup UNTIL it tries to load the last project.  At which point I get the following error sequence.  Its as though my Jave instance cannot reach the Standford server - though why it would need to I'm not sure



Anyone seen this behavior before?  I'll admit, I'm a Java/Tomcat newbie
