Enabling Application Logging on the Server
You can set the global Arbortext Publishing Engine parameter com.arbortext.e3.applicationLog or com.arbortext.e3.applicationLog.Compose to INFO, DEBUG, TRACE in or ALL in e3config.xml. Then, the server side activity of each publishing operation that is implemented in Java will log information to the servlet log.
If you set the global PE parameter com.arbortext.e3.applicationLog.display to true (the default), application log messages are written to the Arbortext Diagnostics window. You can launch Arbortext Diagnostics from the shortcut called Arbortext Publishing Engine Diagnostics in your PTC program group.
