Почему вы хотите пойти на AJAX, когда у вас есть сила Struts. У меня есть простой пример (он проверен) для вас.
MyForm.java
package com.tusar.action;
import java.io.Serializable;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import javax.servlet.http.HttpServletRequest;
public class MyForm extends ActionForm implements Serializable{
private static final long serialVersionUID = 1043346271910809710L;
private String fullName = null;
public String getFullName() {
return fullName;
}
public void setFullName(String fullName) {
this.fullName = fullName;
}
/*This method will be called when you press the reset button
or load the form. You may want to populate the form here also*/
public void reset(ActionMapping mapping, HttpServletRequest request){
String reset = (String)request.getAttribute("myForm.reset");
if ((null != reset)|| ("true".equals(reset))) {
fullName = null;
}
}
}
MyFormSetupAction.java
package com.tusar.action;
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 class MyFormSetupAction extends Action{
/*Set your form-bean properties here*/
@Override
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
MyForm hwForm = (MyForm) form;
hwForm.setFullName("tusar");
return mapping.findForward("success");
}
}
MyFormSuccessAction.java
package com.tusar.action;
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 class MyFormSuccessAction extends Action{
@Override
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
return mapping.findForward("success");
}
}

Каждый раз, когда вы вызываете действие home.do , свойство fullName заполняется "tusar" . Просто прокомментируйте, если вам понадобится дальнейшая ассоциация, я буду рад вам помочь. Спасибо!
