Environment

Applications Manager 9.5.x

Cause

The Java Client's jars directory is missing an ojdbc*.jar Oracle driver

Resolution

In the directory where RunClient.jar, review the jars directory.

The same ojdbc*.jar file that exist in the Master's $AW_HOME/web/classes or %AW_HOME%\web\classes(Windows OS) directory should be found in this directory.

If not found, manually move a copy of the ojdbc*.jar from the master's classes to the the client's jars directory and relaunch the client.
