The Debugging Interceptor provides three debugging modes to provide insight into the data behind the page. The xml
mode formats relevant framework objects as an XML document. The console
mode provides a OGNL command line that accepts entry of runtime expressions, and the browser
mode adds an interactive page that display objects from the Value Stack (it requires the Dojo Plugin).
To use the debugging, first be sure that struts.devMode
is set to true
is enabled through the struts.properties file or struts.xml
file, like:
Code Block | ||||
---|---|---|---|---|
| ||||
<constant name="struts.devMode" value="true" />
|
Then, whenever a page needs debugging, add ?debug=xml
or ?debug=console
or ?debug=browser
to the URL.
