1) Setup a listbox on the page adn add a javascript function to add values to that listbox
function addopt2(nValue, sText){
// this routine adds a new item to our listbox
document.Groups.list2.options[document.Groups.list2.options.length] =
new Option(sText, nValue);
}2) When the user clicks a button fire off this JavaScript
function getLevel2(sCode){
if (sCode == 'NONE' || sCode == ''){
// if they click on an label or empty value
} else {
// a non-empty area
window.open("popfetchlevel2?level=2&code=" + sCode, + ",
gofetch","toolbar=no,menubar=no,location=no,directories=no,status=no,resizea
ble=no,width=100,height=100,left=100,top=100");
}
}This will pop up a window that will call a servlet to interact with the database and then call teh javascript from step 1 to update the page.
Webware Tip: Override writeHTML in the pop-up servlet to bypass yourr layout
step 3 Write your servlet to return an html page containing javascript such as:
<script>
window.opener.addopt2("aheld", "Aaron Held");
window.opener.addopt2("asd", "another name");
</script>window.operner.addopt2 directly calls the javascript from step1

Dear Webware,
I am going to try out you system to-night. It seems similar to Cold Fusion Application Server. I am interested in Python and Jython very much for future projects. I write web applications for customers using Cold Fusion.
I am trying (with difficulty) to do the following, which I can of course do one item at a time by posting the page, but not as follows.
The idea is to create a page, which the user enters a reference number, the program looks up this in the database, puts the relevant description or "not found" on the screen. The user enters the quantity, and the program work out the total,, and puts the next input box on the screen, WITHOUT leaving the page. Possible?
Anyway, if this can be done, I would be grateful for pointers!
Kind regards, Paul Jessup
