A simple Dispatchaction application

1. input.jsp: only provide basic two keys: update and delete, of course, the user may add other keys, and other public ActionForward otherValue added value in Action (ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) { } For example, you joined a to join in Dispatchction

public ActionForward addOrder {form UserManipulcationForm userManipulcationForm = (UserManipulcationForm); / * * other code * / return mapping.findForward ( "delete");} (ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)

INPUT.JSP code: <% @ Taglib Uri = "http://jakarta.apache.org/struts/tags-html" prefix = "HTML"%>
address:

2. Update.jsp: When the user presses the UPDATE button in Input.jsp, final transfer to update.jsp

this is the update page

3. Delete.jsp: When the user presses the delete key in Input.jsp, finally go to delete.jsp

this is the delete page

4. My DispatchAction: the following // Created by MyEclipse Struts // XSL source (default): platform: /plugin/com.genuitec.eclipse.cross.easystruts.eclipse_3.8.0/xslt/JavaClass.xslpackage com.yourcompany.struts .

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.Dispatchaction;

Import com.yourcompany.struts.form.usermanipulcationform;

It is to be noted that the Value in the button is different, and the Dispatchction is used to automate other methods that want to correspond to Value. .

ActionForm:

// create by myeclipse struts // xsl source (default): platform: /plugin/com.genuitec.eclipse.cross.easystruts.eclipse_3.8.0/xslt/javaclass.xsl
