Getting Ip address of client

November 8, 2019January 30, 2017 by manish

When user submit a form along with form data we can get Ip address of client. Lets see one simple program to demonstrate this

   public class Post extends ActionSupport{
           public String execute(){
              HttpServletRequest request = ServletActionContext.getRequest();
              String ipAdd = request.getHeader("X-FORWARDED-FOR");
              if (ipAdd == null) {
                  ipAdd = request.getRemoteAddr();
              }
                System.out.pritln("Ip address of requested client is "+ipAdd); 
               return SUCCESS;
           }
        }

public class Post extends ActionSupport{

public String execute(){

HttpServletRequest request = ServletActionContext.getRequest();

String ipAdd = request.getHeader("X-FORWARDED-FOR");

if (ipAdd == null) {

ipAdd = request.getRemoteAddr();

}

In particular jsp page we can set that page simple by including following tags In jsp page

<s:set name="theme" value="'simple'" scope="page" />
<%@taglib uri="/struts-tags" prefix="s"%>
<!DOCTYPE html>
<html>
    <head>
              <title>Test page</title>

Struts2 Json and Jquery Example

November 8, 2019July 9, 2013 by manish

Here we will fetch a action variable’s value in jsp page using JSON and jquery Here I am using struts 2.3.4 for that we have to include struts-2-json-plugin-2.3.4.jar in class path or include it to your lib folder if you are using any IDE. Action class

package example;

import com.opensymphony.xwork2.ActionSupport;

public class HelloJSON extends ActionSupport {

    private String name;
    private String welcomeMessage;

    @Override
    public String execute() {

        System.out.println("Inside Action name is " + getName());
        setWelcomeMessage("Welcome " + getName() + "!!");
        System.out.println(getWelcomeMessage());
        return SUCCESS;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getWelcomeMessage() {
        return welcomeMessage;
    }

    public void setWelcomeMessage(String welcomeMessage) {
        this.welcomeMessage = welcomeMessage;
    }
}

package example;

import com.opensymphony.xwork2.ActionSupport;

public class HelloJSON extends ActionSupport {

private String name;

private String welcomeMessage;

@Override

public String execute() {

System.out.println("Inside Action name is " + getName());

setWelcomeMessage("Welcome " + getName() + "!!");

System.out.println(getWelcomeMessage());

return SUCCESS;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getWelcomeMessage() {

return welcomeMessage;

}

public void setWelcomeMessage(String welcomeMessage) {

this.welcomeMessage = welcomeMessage;

}

In struts.xml we have to extend json-default and … Read more
