Cause

9.2.x or below:

There is an issue with the connection from the user's PC to the master

9.3.x or above:

Apache service may be stopped

Resolution

Correct any connection issues by enabling client debug and reviewing the Java console logs created during Java Web Client startup process.

Possible connection issues can occur for the following reasons:

9.2.x or below:

Incorrect RMIHostID value in the $AW_HOME/web/classes/Options.properties or %AW_HOME%/web/classes/Options.properties (Windows OS)
Incorrect RMIRegistryPortNumber $AW_HOME/web/classes/Options.properties %AW_HOME%/web/classes/Options.properties (Windows OS)
Firewall between the User's PC and RMIHostID (make sure you can connect to the master's RMIHostID and RMIRegistryPortNumber using telnet or similar command)

9.3.x or above:

Check to see if Apache is up and running. If Apache is stopped, start Apache processes

Additional Information

Client debug can be enabled by following the below procedures:

9.2.x or below:

1. Edit the $AW_HOME/web/Client.jnlp or %AW_HOME%\web\Client.jnlp (Windows OS). Change the below line and save.
