Is anyone successfully using the DispatchAction with html:image tags???
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 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
