Using Beans in JSP

Question

I'm coding a program in java that take a few information from a graph (X axis and Y axis), and then I need to take this information and pass to a JSP page.

this is the java

package view;

public class Axis{
       double[] axisX;
       double[] axisY;
       int test;

       public Axis(){
       }

       public void setAxisX(double[] axisX){
           this.axisX = axisX;
       }

       public void setAxisY(double[] axisY){
           this.axisY = axisY;
       }

       public double[] getAxisX(){
           return axisX;
       }

       public double[] getAxisY(){
           return axisY;
       }
}

Then in the JSP is this what I have to do?

<jsp:useBean id="view" class="view.Axis" scope="session"/>
Test: <%= view.getAxisX() %>

You should start learning `JSTL`. JSP scriplets should not be used anymore. — Rohit Jain, Jul 22 '13 at 14:00

What you are basically trying to do is use Standard Actions :

<jsp:useBean id="view" class="view.Axis" scope="session"/>
<br> X :<jsp:getProperty name="view" property="axisX" />
<br> Y :<jsp:getProperty name="view" property="axisY" />

You can use EL/JSTL for this instead of Standard Actions.
