Java applets work on wired network, but not on wireless
Posted on 2015-01-15
We have two similar data collection systems. Each has a web server. Each web server has menus and some of the selections open Java apps. When we connect to the web servers by Ethernet cable, the Java applets work fine.
However, when we are on our wireless network, one web server will run the Java applications and the other will not. We do get to the home web page with the menus on each, but the Java apps will not.
These are third party systems, so we have limited access to and knowledge of these systems. The third party is suggesting we are blocking access to the system in question. We basically don’t block internal traffic. We did not configure the switch ports from one system differently than the other. The web server in question appears to have communication of some sort, because we can get to the home screen with menus on both.
Is there something that we should consider that we are missing as to the cause of this?
