Question

I’m trying to pass data between 2 Action classes. I’m currently doing this

In my first Action class

doExecute(){
         request.setAttribute("Order_ID", 2);
         // code to find forward to next Action class
}

In the following Action class

doExecute(){
     Object id = request.getAttribute("Order_ID");
     // code to process id
}

However, the getAttribute() method always returns null. How can I property pass data between 2 action forms that follow each other?

Thanks in advance

Answer 1

There are number of ways , you can do this.

Method 1:

Set the attribute in session and then get the value back and then remove it from session.

doExecute(){

 HttpSssion session=request.getSession();
 session.setAttribute("Order_ID", 2);
}

then return it back.

doExecute(){

 HttpSssion session=request.getSession();
 Object id =session.getAttribute("Order_ID");
 session.removeAttribute("Order_ID");
}

Method 2:

Pass the value in url and then get it back from other action but here need to keep in mind that your request doesn’t loss.
