Cancel problem in struts

[Micheal John]

Why I am getting this error when I am clikcing the cancel button in the form.

I am using as follows:

<html:cancel/>

Whether I have to configure action mapping for cancel button also. Struts don't have any in-built cancelling facility?

Error I am getting::

javax.servlet.ServletException: No action config found for the specified url.
org.apache.struts.chain.ComposableRequestProcessor.process(ComposableRequestProcessor.java:283)
org.apache.struts.action.ActionServlet.process(ActionServlet.java:1858)

javax.servlet.http.HttpServlet.service(HttpServlet.java:689)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
 

root cause 
 
org.apache.struts.chain.commands.InvalidPathException: No action config found for the specified url.

In Struts versions 1.2.8 and above you must specify cancellable="true" in your action mapping to enable the cancel button. In a normal action, you can simply call isCancelled(request) in order to determine whether the cancel button was pressed or not. If your action is a subclass of DispatchAction you must code a cancelled method in the Action class.
