Configuring Logging for Debugging

To enable logging, add the corresponding line to the <js‑webapp>/WEB‑INF/ file, in the form:

  log4j.logger.<logger-classname> = <log-level>, <output-type>

For example:, stdout, fileout

You must restart the server for your changes to take effect. For more information about log configuration, see the JasperReports Server Administrator Guide.

You can reduce impact on performance by restricting logging to functionality that you are interested in, for example, to a subset of Spring Security instead of all of Spring Security. “Useful Logger Classnames for External Authentication” shows some logger classnames commonly used when debugging authentication.
