i’ve done a struts2 login action using mysql database which is as shown below.

  • 0

i’ve done a struts2 login action using mysql database which is as shown below.
for the initial login action i’m using LoginActionBean where i checks the username and password. After loging into the Main page there i need to get the team details again from the database. For that i used jsp scriplet tags. Can anyone tell me another way in which to access the team details from the database through javabeans (not through LoginActionBean) and without using the jsp scriplets.

login.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>

    Well you have already done most of the work, so you can do some simple things like in you action class

    1. Create a bean say TeamDetails with properties you want to show in JSP
    2. define this bean in your Action class and fill it using DB call
    3. use OGN in your JSP to access data and show it using struts2 tag.

    Action class:

    public class TeamDetailAction extends ActionSupport{
  List<TeamDetailData> teamDetails;
   //getter and setter

 public String execute() throws Exception{
             teamDetails=fill it by retrieving from BD
    }
}

    TeamDetailData Java

    public class TeamDetailData{

 private teamMemberName;
 // other properties
//getter and setters
}

    on your JSP using OGNL iterator tag to show the data

    JSP page

    <s:iterator value="teamDetails">
  <p>Name : <s:property value="teamMemberName"/></p>
</s:iterator>
