I have the following html page, the servlet class and the bean class implemented in my eclipse project that runs on wildfly 8.
The problem I have is every time I call the servlet with some values the add operation in the bean class returns a zero. I know I'm not doing a trivial thing correct. What should I change to get the correct value from the add operation.
AddServlet.java
import java.io.IOException;
import java.io.PrintWriter;
import javax.ejb.EJB;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import ejb.AddEjb;
@WebServlet("/AddServlet")
public class AddServlet extends HttpServlet {
private static final long serialVersionUID=1L;
@EJB
AddEjb bean;
public AddServlet() {
super();
}
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
PrintWriter out=response.getWriter();
int i=Integer.parseInt(request.getParameter("t1"));
int j=Integer.parseInt(request.getParameter("t2"));
bean.setI(i);
bean.setJ(j);
bean.add();
out.print("Addition using bean is test EJB : " + bean.getK());
}
}
AddEjb.java
package ejb;
import javax.ejb.LocalBean;
import javax.ejb.Stateless;
@Stateless
@LocalBean
public class AddEjb
{
private int i,j,k;
public AddEjb() {
}
public int getI() {
return i;
}
public void setI(int i) {
this.i = i;
System.out.println("i set" + this.i);
}
public int getJ() {
return j;
}
public void setJ(int j) {
this.j = j;
System.out.println("j set" + this.j);
}
public int getK() {
System.out.println("K returned" + this.k);
System.out.println("K returned" + k);
return this.k;
}
public void setK(int k) {
this.k = k;
System.out.println("k set" + this.k);
}
public void add()
{
this.k = this.i + this.j;
System.out.println("k set" + this.k);
}
}
