The Web Services Invocation Framework (WSIF) offers trace points at the opening and closing of ports, the invocation of services, and the responses from services. WSIF also includes a SimpleLog utility that can run trace when you are using WSIF outside of WebSphere Application Server.
Why and when to perform this task
If you want to enable trace for the WSIF API within WebSphere Application Server, and have trace, stdout and stderr for the application server written to a well-known location, see Enabling tracing and logging.
To trace the WSIF API, you need to specify the following trace string:
wsif=all=enabled
To enable the WSIF SimpleLog utility, through which you can run trace when using WSIF outside of WebSphere Application Server, complete the following steps:
Steps for this task
org.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.LogFactoryImpl org.apache.commons.logging.Log=org.apache.commons.logging.impl.SimpleLog
org.apache.commons.logging.simplelog.defaultlog=trace org.apache.commons.logging.simplelog.showShortLogname=true org.apache.commons.logging.simplelog.showdatetime=true
Result
The SimpleLog utility writes trace to the System.err file.Related reference
