general question - building webpage with java app on it..

[Mihail Kravsun]

Hello,
Dear experts, please help! What I am looking for is just a general suggestion on what tools/general approach to use to do the following:
I need to create a website which will have a single webpage, with very limited number of components on it: memo field (should be able to copy/paste large (1000 lines?) of text)), drop-down list to select something, just an input field and a button to click. Then I click the button, the app does something and displays results on the same webpage.
The solution should be based on free software. I was thinking to host this webpage on the winxp or win2003 server, IIS is available, but can use apache as well, I was thinking about tomcat as app server. But not sure which gui (light weight) to use to create a webpage...
thank you in advance!

Just use HTML.
Have Javascript firing off an Ajax call to your server, which will return the result (possiby a JSON string, depends on what data it is). More Javascript to process that result.

Doesn't matter what the server has on it.

I agreed with Tolls. According to your requirement, HTML controls with JS/AJAX calls is more than enough. Are you doing any database interactions?
