We have this Dispatch Action:

package dhs.vcm.vis.action.finishReason;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.actions.DispatchAction;
import dhs.vcm.vis.business.FinishVisitReasonBO;
import dhs.vcm.vis.db.exception.Fin_Vst_Rsn_Exception;
import dhs.vcm.vis.entity.Constants;
import dhs.vcm.vis.entity.FinishVisitReason;
import dhs.vcm.vis.form.finishReason.FinishReasonDeleteForm;
import dhs.vcm.vis.form.finishReason.FinishReasonUpdateForm;
import dhs.vcm.vis.form.finishReason.FinishVisitReasonFormConverter;

/**

public final class DispatcherAction extends DispatchAction {

 // --------------------------------------------------------- Public Methods

 /**
  * Process the specified HTTP request, and create the corresponding HTTP
  * response (or forward to another web component that will create it).

  */

 public ActionForward delete(
  ActionMapping mapping,
  ActionForm form,
  HttpServletRequest request,
  HttpServletResponse response)
  throws IOException, ServletException {

  // create a new delete form to hold the data for the delete jsp
  FinishReasonDeleteForm deleteForm = new FinishReasonDeleteForm() ;
  deleteForm.setShortDescription(
(String)request.getParameter("shortDescription") ) ;
  request.setAttribute(Constants.FINISH_REASON_DELETE_KEY, deleteForm ) ;

  // Forward control to the specified success URI
  return (mapping.findForward("delete"));

 }

 public ActionForward insert(
  ActionMapping mapping,
  ActionForm form,
  HttpServletRequest request,
  HttpServletResponse response)
  throws IOException, ServletException {

  // Forward control to the specified success URI
  return (mapping.findForward("insert"));

 }

 public ActionForward update(
  ActionMapping mapping,
  ActionForm form,
  HttpServletRequest request,
  HttpServletResponse response)
  throws IOException, ServletException {

  // get the row to update using the selected reason Id
  FinishReasonUpdateForm updateForm = new FinishReasonUpdateForm() ;
  FinishVisitReasonBO reasonBO = new FinishVisitReasonBO() ;
  FinishVisitReason reasonForUpdate = new FinishVisitReason() ;

  try {
   reasonForUpdate =
reasonBO.getByReasonID(Integer.valueOf(request.getParameter("finishReasonID"
)).intValue()) ;
  }catch (Fin_Vst_Rsn_Exception fvre) {
   System.out.println(" Finish Visit Reason Exception caught: " +
fvre.getMessage()) ;
  }
  FinishVisitReasonFormConverter.toFinishReasonForm(reasonForUpdate,
updateForm) ;

  updateForm.debug() ;

  request.setAttribute(Constants.FINISH_REASON_UPDATE_KEY, updateForm ) ;

  // Forward control to the specified success URI
  return (mapping.findForward("update"));

 }

}

That works with this JSP using image buttons....

Re: DispatchAction with Image buttons

[Robert Taylor <ro...@yahoo.com>]

I haven't to date, but definitely will in my next
project so I have done some research on it. 

>From what I can tell neither DispatchAction nor
LookupDispatchAction will support this out of the box,
but there is a pretty simple modification that can be
made to DispatchAction to make it work.

I explain my ideas in this thread:

http://www.mail-archive.com/struts-user@jakarta.apache.org/msg33005.html

Unless someone has already implemented this, I will
need to and will post it when done.
