Trace and logging for WSIF

 

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 WAS.

 

Overview

To enable trace for the WSIF API within WAS, and have trace, stdout and stderr for the appserver written to a well-known location, see Enabling tracing and logging.

To trace the WSIF API, we 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 WAS, complete the following steps:

 

Procedure

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.

 

Results

The SimpleLog utility writes trace to the System.err file.
