How exactly are you trying to call a Java class from JavaScript?

yeah i'm crap at explaining things.. this is what I've done. My Java class is Stemmer and I need to use the stemWord method. Thought I should try and create a constructor?
What you think?
<html>
<head><title>JavaScript to Java Stemmer Example</title>
<script language="JavaScript1.2">
function swhandler()
{
var word = document.stemmer.word.value;
var stemObj = new Packages.Stemmer();
var stemmedWord = stemObj.stemWord(word);
document.stemmer.stemmedWord.value = stemmedWord;
<!-- Call Java Stemmer class.
-->
}
</script>
</head>
<body bgcolor = "white">
<!--
This is an HTML form that allows the user to enter data and allows JavaScript to
display the results it computes using a Java Stemmer Class back to the user.
-->
<form name="stemmer">
<table>
<tr>
<td>1)</td>
<td>Please insert word to be stemmed:</td>
<td>
<input type="text" name="word" size="20">
</td>
</tr>
<tr>
<td colspan="3"><input type="button" value="Stem" onClick="swhandler();"></td>
</tr>
<tr>
<td>2)</td>
<td>Stemmed Results:</td>
<td><input type="text" name="stemmedWord" size="20"></td>
</tr>
</table>
</form>
</body>

I don't believe you can access Java classes like that in JavaScript.

I'm not entirely sure if you can at all. Have you tried a Google search?

Yeap..all I found was stuff on JSObject or LiveConnect or using Applets and I don't think thats what I need, may be the LiveConnect part? I want to directly access and use my Java classes from my JavaScript code. I want to go from JavaScript to Java not Java to JavaScript. Do you have any ideas of what to try?

Depending on what they do, you could recode your Java classes in JavaScript.

No I can't do that..because I will be needing to access alot of the Java classes I've already wrote so I wanted to figure the whole Javascript to Java communication thing out now if I can...any other suggestions? There has to be some way to do it?

Try asking in the Java forum in case anyone there has had a similar requirement before.
As I said, I don't think it can be easily done (and certainly not in any cross-browser or cross-platform way).
