The Ajax proxy uses the Jakarta Commons Logging facility. The Jakarta Commons Logging facility provides a logging framework that can integrate other logging facilities, such as log4j and java.util.logging. The facility logging configuration that you use depends on the application server that you are using to deploy the Ajax proxy.
WebSphere® Application Server version 6.1, 7.0, or 8.0
The Ajax proxy integrates with the application server logging facility and supports INFO level and FINEST level logging. Select the com.ibm.ws.ajaxproxy package from the Logging and tracing panel. Select finest to enable the TRACE level logging. To view request and header information sent to and from the Ajax proxy, enable tracing for the com.ibm.ws.ajaxproxy.servlet package. INFO level logging is enabled by default in the application server.
Other application servers
WebSphere Application Server Community Edition uses the log4j logging package. Edit the server-log4j.properties file to add logging for the Ajax proxy servlet. Add the following entry:
log4j.category.com.ibm.ws.ajaxproxy.servlet.ProxyServlet=DEBUG
