Question

In my application I am trying to register a user by adding his details to the database and after success fully insert these values. I need to display form input page but on result page I am not getting any output.

My ACTION CLASS IS

package action;


import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

import dao.Empdao;
import model.Empmodel;
public class Empaction extends ActionSupport implements ModelDriven<Object>{
private static final long serialVersionUID = 1L;
Empmodel modelobj;

    public Empmodel getModelobj() {
    return modelobj;
}

public void setModelobj(Empmodel modelobj) {
    this.modelobj = modelobj;
}
    public String execute() throws Exception{
        Empdao empdao = new Empdao();
        int queryResult = empdao.registration(modelobj);


        if (queryResult==0)
        {   
          addActionError("it is a dublicate entry please enter anothe id");
         return ERROR;
        }   
        else{

         return SUCCESS;    
            }

}


    @Override
    public Object getModel() {
        modelobj = new Empmodel();
        return null;
    }

}

Success.jsp is

<body>


  first name : <s:property value="modelobj.firstname"/> <br>
last name :<s:property value="modelobj.lastname" />
<s:property value="modelobj.id" />
<s:property value="modelobj.gender" />
<s:property value="modelobj.dob" />
<s:property value="modelobj.maritalstatus" />
<s:property value="modelobj.email" />
<s:property value="modelobj.joiningdate" />

<s:property value="modelobj.country" />

<s:property value="modelobj.city" />
<s:property value="modelobj.pincode" />
<s:property value="modelobj.mobileno" />
<s:property value="modelobj.groups" />

</body>

Solution

You are redirecting the page on success that is wrong because you loose values needed to display results. Use

<result name ="success">/Registration/success.jsp</result>

or simply

<result>/Registration/success.jsp</result>

BTW, you only have getters & setters for firstname and lastname, so the only these properties will display. If you want to display other properties then you should add correcponding methods to fields.

You may read the servlet API javadoc to make clue what may cause result type="redirect".

For further compare the difference between forward and redirect results consider this thread.

OTHER TIPS

If type=redirectAction then you have to mention the Action name without any extensions if its only redirect then you have to mention including the action name and extension, For your Question it was because of redirect the problem happened.

Even after redirecting to some page and when you come back to the result page , and if you want to retain data then its better you better put in session .

Do not redirect you page remove it and use 

<result name ="success">/Registration/success.jsp</result> in you struts.xml file
