The Web service also logs error messages in the instance-name.wsa.log file. The serviceLoggingLevel property affects logged information for a single deployed Web service. You can set the serviceLoggingLevel property in the Web service properties file (*.props) or by using the wsaman utility. This setting takes effect immediately at run time. The serviceLoggingLevel property provides information at the following logging levels:
Level 2 (Basic) — Logs severe errors that affect the Web service as a whole and user authentication errors. Use Level 2 when the Web service is running in production.
Note: During production, raise the logging level of only the Web Service being debugged.
Level 3 (Verbose) — Logs Web service request execution, SOAP message processing errors, and user authentication success. Use this value during Web service development to provide more information for each Web service request error.
Level 4 (Extended) — Logs error detail and request parameter values. Use Level 4 in a development environment.
