If you need to log SOAP information in Websphere, you can turn on trace logging and set the following value in the Change Log Details Level (Logging and Tracing > ServerName > Diagnostic Trace Service > Change Log Detail Levels) :


This will log only the SOAP web service messages without seeing all of the other goop that can make the trace log hard to read through.

Make sure you have a valid trace log file defined first (${LOG_ROOT}/trace.log)
