Servlet Tracing

Servlet tracing is enabled by setting Trace Flag to ON in the General tab of the ReportCaster Server Configuration tool, or by selecting the Servlet Traces menu option. Once you have enabled servlet tracing, you can use the Trace File setting in the General tab of the ReportCaster Server Configuration tool to specify the path and file name on the Web server where the servlet tracing statements will be written. You must type the fully qualified path of a location accessible on the Application Server/Servlet Engine. The Trace File setting is ignored if the Trace Flag setting is OFF.

Servlet tracing enables tracing for all servlets executed by ReportCaster, including the ReportCaster API. Servlet tracing provides information about queries to, and maintenance of, the ReportCaster Repository. This includes events that occur during the scheduling of a job.

Note: You should also view the Application Server log files. By default, Apache Tomcat trace files are located in the C:\Program Files\Apache Software Foundation\Tomcat 5.0\logs\ directory. If ReportCaster is configured with Managed Reporting, you should also view the WebFOCUS Client servlet trace files. In the WebFOCUS Administration Console, you can access these trace files by clicking Configuration, Diagnostics, Traces, WFServlet.

Example: Using Servlet Tracing

The following is an excerpt from a servlet.trc trace file. It shows initialization parameters, the servlet request, and the servlet activity associated with a scheduled job. Note that the beginning of the trace file shows the system properties (for example, Java classpath and platform information), while the cookie information (not shown) follows this section.
