A hint for the “Object foo is not a known entity type” errors from Glassfish
As a JavaEE-codemonkey you have perhaps noticed this error:
java.lang.IllegalArgumentException: Object: Ting@193c227 is not a known entity type.
This will occur when you have redeployed an app f.ex through Eclipse to Glassfish, the Glassfish server has not quite understood that it`s time to update its version, so what you need to do then is to simply restart the server (or domain).
One possible solution for Glassfish cluster node-agent startup problems
Just a quick hint for those of you who are experiencing problem with getting node-agents up and running in a Glassfish cluster.
If the problem is that the asadmin start-agent command simply times out/uses a long time to start, and even possibly returning a filenotfoundexception. The problem could be as simple as a firewall blocking traffic to/from the master-node. A quick way to check it is to simply disable the FW.
Note that if the master-node does not see the node-agent status, it is also caused by FW-issues, fix the FW and then restart the node-agent(s), then it all should work like a charm!
