Status: Verified
SYMPTOM(s):
Progress Explorer
Unable to connect to Admin server from Progress explorer
Progress Explorer hangs for +/- 10 minutes and then returns a Java error
error unmarshalling return; nested exception is:
java.io.InvalidClassException: com.progress.common.networkevents.EventInterestObject_Stub; Local class not compatible
Admin server is running on Linux
PROADSV -Q says AdminServer is alive
NSMAN command works correctly
Network on the Linux machine is set correctly
There is no firewall between AdminServer and machine with Progress Explorer
A second version of Progress is installed on the Windows machine
AdminServer for the second version of Progress is Started
FACT(s) (Environment):
Linux Intel
Windows
Progress 9.x
OpenEdge 10.x
CAUSE:
A file clash is occurring causing Progress Explorer to use the wrong Java version. Since Progress Explorer must be exactly the same version as the AdminServer that it is trying to connect to then the connection fails.
FIX:
Option #1
Stop the AdminServer for the other version of Progress.
Set the Startup Type of the Service to Manual.
Reboot the PC.
Start the Progress Explorer that has the same version as the AdminServer on the remote machine.
Establish the connection.
Option #2
Uninstall the second version of Progress.
Reboot the PC.
Start the Progress Explorer that has the same version as the AdminServer on the remote machine.
Establish the connection.
