Struts 1.3.10 DispatchAction issue

[Joe San]

Guys,

I have a DispatchAction class defined as below:

public class SearchFormAction extends DispatchAction {

    public ActionForward populate(ActionMapping mapping, ActionForm actionForm, HttpServletRequest request, HttpServletResponse response) {
        //call to the service and populate the form bean
        return mapping.findForward("success");
    }
}

My struts-config.xml entry looks like this:

        <action path="/searchForm" type="com.myapp.web.content.action.SearchFCAPFormAction"
                name="searchExistingForm" scope="request" validate="true"
                input="/pages/content/searchForms.jsp" parameter="method">
            <forward name="success" path="/pages/content/searchResults.jsp" />
            <forward name="error" path="/pages/common/error.jsp" />
            <forward name="noResult" path="/pages/content/noResults.jsp" />
        </action>

I call this by clicking a hyperlink which calls an action when clicked:

<form action="searchForm.do?method=populate">

When I click the hyperlink to call my searchForms.jsp, I get the following error:

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

Not able to figure out why this happens. Any suggestions?

Are you sure the the the class you mapped

<action path="/searchForm" type="com.myapp.web.content.action.SearchFCAPFormAction"

is same as the class you post.

public class SearchFormAction extends DispatchAction {

    public ActionForward populate(ActionMapping mapping, ActionForm actionForm, 
HttpServletRequest request, HttpServletResponse response) {
        //call to the service and populate the form bean
        return mapping.findForward("success");
    }
}

[Joe San]

That was a typo. It is the same by the way.

Code looks ok, some RnD
Use Struts tag:

<html:form action="..">

If that doesn't work, pass the hidden input param named "method" with value = "populate"
