Action Question

[Luke Shannon]

Hello;

This is my firs time working with struts and I am working in an existing application. I need to expose a method in an Action and am getting a "does not contain specified method" exception. I suspect I have not configured the action correctly (do I need a form bean?). Also I have an extra parameter (page) that I am not sure how to map.

Any tips?

Below are my details.

Here is the Struts config

<action
            path="/reportsBaseAction"
			type="action.ReportsBaseAction"
            input="/reportsBaseAction.do?method=exportReportToHTMLPage"
            scope="request"
            parameter="method">
           <forward name="reportDetailPage" path="/WEB-INF/pages/reportDetail.jsp"/>
</action>

In an action, that extends DispatchAction, I have the following method (code reduced for brevity):

protected ActionForward exportReportToHTMLPage(ActionMapping mapping,
		    ActionForm form,
		    HttpServletRequest request,
		    HttpServletResponse response) {
	...
		return mapping.findForward("reportDetailPage");
	}

I call the action like this.

href="/myapp/reportsBaseAction.do?method=exportReportToHTMLPage?page=<%=pageIndex + 1%>"

The error I get is:

java.lang.NoSuchMethodException: Action[/reportsBaseAction] does not contain specified method (check logs)

I'd first try correcting the URL:

href="/myapp/reportsBaseAction.do?method=exportReportToHTMLPage?page=<%=pageIndex + 1%>"

This has two question marks ("?") in it; the second one should be an ampersand ("&"). If I had to guess I'd say it's checking after the last question mark for the request parameters--but that's just a guess.

Thanks Dave. The URL was indeed wrong, also it looks like I did need to add the pageIndex parameter to the form bean. I did find out the Action I was working in (and trying to map in the Struts config) is extended by another Action that is already configured. I was able to access my method through this class so I no longer needed the mapping I posted earlier.

I have an experienced struts person working with me now so everything is back on track.

Thanks for your reply.
