got a big problem ...
We got a task we cant solve (Obviously, if we could i wouldnt ask here).
Our task is:
A page with 2 Textfields and 1 Button.
You shall be able to enter nothing else than numbers in these Textfields (floats or ints, nevermind)
When you enter a value to the last Text Field, there should automatically appear a new Text Field under the others.
So that you can enter as many numbers as you want to.
The button shall sum these numbers.
BUT the sum shall be displayed on another page, and the sum itself shall be calculated on the first page and shall be saved in Beans class.
So, we made 2 pages and one bean.
Numbers.jsp, Sum.jsp and Add (this is the bean)
The Sum.jsp takes the bean and just displays the result.
Thats very easy ...
Our Problem is, we dont know how to write into the bean from dynamically generated textfields and without pressing a button, because the button shall redirect to Sum.jsp.
Right now we have a workaround ... we reload the page and take the "request.getParametersMap()" and write this into the bean.
But we dont like this idea very much ...
So what you want is for us to do your homework for you. That isn't going to happen. You will learn nothing if someone else does this for you.
Make an effort. If you run into problems, post the code specific questions you have here and we'll be more than happy to help.
Well, no i dont want you to do my homework ...
We already spent hours on this task, but we dont find a way to solve it in a proper way.
We just want to know how to save from dynamic generated text fields into a bean.
As far as i know you can use "c:set" just in your HTML-Code.
Server just knows about them if we send a new request, but thats quite "dirty code"
