Answer 1

Hi,
Thank you for response.I have modified the program as what you told me.it can startup now,But it suspended at LoginAction,the running message is printed as following:
LoginAction.execute(ActionMapping, ActionForm, HttpServletRequest, HttpServletResponse) line: 18
RequestProcessor.processActionPerform(HttpServletRequest, HttpServletResponse, Action, ActionForm, ActionMapping) line: 419
RequestProcessor.process(HttpServletRequest, HttpServletResponse) line: 224
ActionServlet.process(HttpServletRequest, HttpServletResponse) line: 1192
ActionServlet(HttpServlet).service(HttpServletRequest, HttpServletResponse) line: 709
when I click on the information "RequestProcessor.processActionPerform",it popup a message that show "Source not found ,The jar file Struts.jar has no source attachment",Does it need to attach the source of struts.jar?
I list the LoginAction.java as following:
package classmate;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
public final class LoginAction extends Action{ 
public ActionForward execute(
     ActionMapping mapping,
     ActionForm form,
     HttpServletRequest request,
     HttpServletResponse response) throws Exception {
     UserForm userform = (UserForm) form;
     String name = userform.getName();
     String psw = userform.getPsw();
     if("jenny".equals(name) && "hi".equals(psw)){
          UserLoginLog ul = new UserLoginLog();
          ul.save(name,psw);
          return mapping.findForward("successed");     
     }else{
          return mapping.findForward("failed");
as I debuged the program,the breakpoint line "UserForm userform = (UserForm) form; "
and the UseForm.java is listed as following:
package classmate;
import org.apache.struts.action.ActionForm;
public class UserForm extends ActionForm{ 
     private static final long serialVersionUID = 1L;
     private String name = null;     
     private String psw = null;     
     public UserForm(){}
     public void setName(String name) {
          this.name = name;
     public String getName() {
          return name;
     public void setPsw(String psw) {
          this.psw = psw;
     public String getPsw() {
          return psw;
and I have written the web.xml and struts-config.xml in above message.
how can I run through the breakpoint line so that I can access the ActionForm's Data? if anybody can tell me how to resovle it ,Please reply to help me. Thanks you.
