I read this from other place. It would be interesting since many posters here are teches.

An example of Java-induced blindness:

I know Javascript and Java aren''t the same, but there's an analogy here that might be interesting:

I've been working on building some sample Channels for a new version of WinMag's BrowserTune.

Microsoft uses CDF, and this is what I had to add to set up an Active Channel:

<a href="channel.cdf"><font size="1">Subscribe via IE4 Active Channel</font></a>

But Netscape does *everything* in Java, and here's what it took to set up a Netcaster Channel:

<script LANGUAGE="JavaScript">
function needNetcaster() {
window.open("http://netcaster.netscape.com/finder/need_netcaster.html","need_netcaster",
"width=629,height=400,titlebar=yes,toolbar=no,location=no,directories=no,status=yes,menubar=no,
scrollbars=yes");
}
function addChannelAPI() {
needNetcaster();
}
</script> <script LANGUAGE="JavaScript1.2">
var chanURL = "http://www.langa.com";
var chanName = "Langa.Com";
var chanIntervalTime = -6; //max 1380
var chanAbsoluteTime = 60;
var chanMaxCacheSize = 1024000; //max 5120000 Kb
var chanDepth = 1; //max 2 levels
var chanActive = 1;
var chanWidthHint = 640;
var chanHeightHint = 480;
var chanMode = "window";
var chanType = 1;
var getChannelObject = null;
var addChannel = null;
var nc = null;
var ncActive = 0;
var poller = null;
ÿ
function activateNetcaster() {
nc.activate();
}
function netcasterSniffer() {
var isClientOK = (navigator.appName == 'Netscape' && navigator.appVersion.substring(0,1) >= 4 );
if(isClientOK == false) {
alert('You must be running an application that supports \n"JavaScript 1.2" to subscribe to this channel.');
return;
}
if (!components["netcaster"]) {
alert("This page requires the Netcaster component.");
needNetcaster();
}
else {
nc = components["netcaster"];
if (nc.active == false) {
alert("Activating Netscape Netcaster. \n\nPlease click the Add Channel button
\nagain after Netcaster has completed\nloading to subscribe to this channel.");
activateNetcaster();
}
else {
ncActive = 1;
addChannelAPI();
}
}
}
function addChannelAPI() {
if (ncActive == 0) netcasterSniffer();
else {
nc = components["netcaster"];
eval("import nc.getChannelObject;");
eval("import nc.addChannel;");
var chan = getChannelObject();
chan.url = chanURL;
chan.name = chanName;
chan.intervalTime = chanIntervalTime;
chan.absoluteTime = chanAbsoluteTime;
chan.maxCacheSize = chanMaxCacheSize;
chan.depth = chanDepth;
chan.active = chanActive;
chan.widthHint = chanWidthHint;
chan.heightHint = chanHeightHint;
chan.mode = chanMode;
chan.type = chanType;
addChannel(chan);
}
ncActive = 0;
}
<script><font size="1"><a HREF="#" onClick="addChannelAPI(); return(false);">
Subscribe via Netscape Netcaster</a></font>

And all that code gets downloaded every time you visit the page, whether you're interested in a Channel or not. (Or, the web-builder has to insert a scripting filter to include the above code for when a 4.0 browser grabs the page.) Either way, yuk.

JavaScript isn't Java, but I think the above illustrates the kind of problems you run into when you try to use one tool to solve all your problems.

Java---and JavaScript--- have their place, but you run into all kinds of problems when you ask either or both to become a kind of universal tool that can do anything.
