HTML & CSS implementation

[athageor]

Hello there community!
So I have decided to use Apache Wicket for my bachelor's thesis! :)  
I'm very new here.
I have written a Java program, whose input is two (2) Strings (two  
names). The ouptut is

certain arraylists, not quite relevant here.
So far I've managed to print the output in a blank internet page using  
localhost.


I have created a fairly simple UI using HTML and CSS. Much like a  
login screen requires username and password, this menu requires  
String1 and String2.

What I wish to do is the following:
I want the values of the two Strings, that are manualy assigned in the  
Java code, to be the values entered in the
two boxes of the UI, and when the "Run" button is pressed, the user is  
redirected to another page, where the output for the two Strings is  
printed.


I would like some advice as to how this is implemented and where to look.
If anyone is willing to provide more specific info, I can of course  
provide you with the code (only the few bits mentioned above are of  
any importance, no need to waste your time by having you look into it  
in detail.)


I would greatly appericiate any help I can get!!
Thanks in advance everyone! And thank you community for being  
extremely helpful in the past!


Cheers,
George

Odd Error

[athageor]

I am simply trying to implement an existing example of The  
RepeatingView Component as it is displayed in the documentation.

The .html file:




Apache Wicket HelloWorld




[Label's message goes here]




(NOTE: If I use "listItems" instead of ':listItems' as it is in the  
tutorials, I get another error specifically telling me that  
':listItems' was expected instead...)


and in the Java file I am only adding initializing & components:
RepeatingView listItems = new RepeatingView("listItems");

listItems.add(new Label(listItems.newChildId(), "green"));
listItems.add(new Label(listItems.newChildId(), "blue"));
listItems.add(new Label(listItems.newChildId(), "red"));
}
}

Instead of the components being displayed, the server either denies me  
access or returns me this error:
Last cause: This container is already dequeing: [Page class =  
com.thesis.HomePage, id = 0, render count = 0]


Any ideas, anyone?

Thanks in advance!!

Newbie Question

[athageor]

The question is about as simple as it gets:
in the HelloWorld! example a single String is printed on the server by  
adding one new Label in the .java file in a such manner:

 add(new Label("id", "what I actualy want to print");

Therefore, in order to print a single string I must've predefined it  
the .html file:

 "Message goes here"

The question is: how do I print the contents of an ArrayList with an  
unknown and non-static ammount of Strings? In other words, how do I  
print a number of Strings without having predefined their ammount in  
the html file ?


Thanks in advance!
