ErrorRendererpublic class ErrorRenderer extends Renderer | Shows an error page. Since errors are frequently caused by improperly
configured JAR files, XML And XSLT are not used by this class.
If XML and XSLT were used, then the same CLASSPATH issue that caused
the original exception to occur would probably cause this page
to fail as well. |
