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"
Let me start off by saying that I apologize in advanced if this isn't the correct forum for this question, but there didn't seem to be a forum that exactly matched the question/issue I'm having.
I'm a VB.NET developer and I like to expand by knowledge by trying to program things from scratch that are already implemented ih the.NET framework. My current project is programming a SMTP server using just sockets. I've already read the RFC on SMTP and my company has an Exchange Server (2007) that I was going to use for testing.
The web address of the server is exchange.mycompany.com and I used reverse DNS to get the IP adress. The domain name does have a MX record a well. From the command prompt on my computer (which is running Win7 Professional) I tried using telnet to connect on port 25. I tried using the domain name as well as the IP address, but both times it said it couldn't connect to the server on port 25.
I checked the settings ih Outlook and the port is correct. I then tried connecting on port 110, and some other ones that are sometimes used, and it gave the same error message.
Next I connected to the Exchange server through VPN and tried telnet again on port 25 and this time it worked. However in the SMTP banner it said remote.mycompany.com instead of exchange.mycompany.com. So I disconnected from the VPN and tried the telnet again on all the ports I initially tried but used remote.mycompany.com but again got the same error message. I did an IP address lookup and remote.mycompany.com and exchange.mycompany.com point to the same IP address.
I then used mxtools.com and dnsstuff.com (I think that was the adress) and used their SMTP tools to see of they could connect. I entered mycompany.com as the domain name and they looked up the MX record, which returns exchange.mycompany.com as the SMTP server, and both tools were able to connect with no issues identified.
So my questions: 1) If the MX record list exchange.mycompany.com as the SMTP sever, why does the banner return remote.mycompany.com? 2) Why can't I connect the SMTP server through telnet unless I'm connected through VPN, but the two websites I used to test it the connection worked?
Obviously the server works because because the two websites can connect to it, I can when I'm in VPN, and other servers can because I receive email on my corporate account. What could prevent my computer from connecting to the SMTP server through telnet when I'm not on VPN. I should also mention that I even tried turning off all my anti-virus software to make sure that it wasn't blocking it.
Any help would be greatly appreciated since I assuming if I can't telnet in I most likely wouldn't be able to connect through sockets so I can't start working on my project until I solve this.
It is unlikely that you can connect directly from home to your company server through normal internet, as most company exchange servers do not allow connections from outside their intranet. When you use VPN you are, presumably, going via the company's intranet and thus seen as a valid user.
One of these days I'm going to think of a really clever signature.
I'm not trying to connect to it so I can send an email through the server. What I was trying to understand how to do was to deliver and email to it. For example, if I build an SMTP server and a client which connects to my that SMTP server and I want to send an email to email@example.com (where mycompany.com is hosted on the Exchange server), how would the SMTP server I created connect to the Exchange server in order to deliver the email? Doesn't the Exchange server have to allow some sort of connection from outside the intranet in order to receive emails from other domains (gmail, yahoo, etc.)?
