CKSource

CKFinder for Java contains a special debugging mode that makes it easier to troubleshoot the application. This mode can be turned on in the WEB-INF/web.xml file, by setting a new <init-param>debug</init-param> node to true.

<servlet>
	<servlet-name>ConnectorServlet</servlet-name>
	<servlet-class>com.ckfinder.connector.ConnectorServlet</servlet-class>
	<init-param>
		<param-name>XMLConfig</param-name>
		<param-value>/WEB-INF/config.xml</param-value>
	</init-param>
	<init-param>
		<param-name>debug</param-name>
		<param-value>true</param-value>
	</init-param>
	<load-on-startup>1</load-on-startup>
</servlet>

For more information on the web.xml file refer to the Integration article.

With the debugging mode on, CKFinder returns detailed exception information when an error occurs.

The debugging mode should not be turned on by default on a production server and should only be used to diagnose a problem when CKFinder does not work as expected.
