Trace and logging for WSIF

If you want to enable trace for the Web Services Invocation Framework (WSIF) API within WebSphere Application Server, and have trace, stdout and stderr for the application server written to a well-known location, see one of the following topics:

• Enabling tracing and logging.

• .

WSIF offers trace points at the opening and closing of ports, the invocation of services, and the responses from services.

To trace the WSIF API, you need to specify the following trace string:

wsif=all=enabled

WSIF also includes a SimpleLog utility through which you can run trace when using WSIF outside of WebSphere Application Server. To enable this utility, complete the following steps:

1. Create a file named commons-logging.properties with the following contents:

   org.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.LogFactoryImpl org.apache.commons.logging.Log=org.apache.commons.logging.impl.SimpleLog 

2. Create a file named simplelog.properties with the following contents:

   org.apache.commons.logging.simplelog.defaultlog=trace org.apache.commons.logging.simplelog.showShortLogname=true org.apache.commons.logging.simplelog.showdatetime=true 

3. Put both these files, and the commons-logging.jar file, on the class path.

ResultThe SimpleLog uitility writes trace to the System.err file.
