java.lang.Objectcom.opensymphony.webwork.interceptor.debugging.DebuggingInterceptor
public class DebuggingInterceptor
Provides several different debugging screens to provide insight into the data behind the page. The value of the 'debug' request parameter determines the screen.
This interceptor only is activated when devMode is enabled in webwork.properties. The 'debug' parameter is removed from the parameter list before the action is executed. All operations occur before the natural Result has a chance to execute. The value of the 'debug' request parameter determines the screen.xml
- Dumps the parameters, context, session, and value
stack as an XML document.console
- Shows a popup 'OGNL Console' that allows the
user to test OGNL expressions against the value stack. The XML data from
the 'xml' mode is inserted at the top of the page.command
- Tests an OGNL expression and returns the
string result. Only used by the OGNL console.<action ...> <interceptor-ref name="debugging" /> .... </action>
