Hello,

can someone please tell me how to ascertain what version (if any) of Java is
installed in a WinXP platform?

my friend needs some kind of Java module installed so that she can do a
tutorial for an online registration service.

any help would be appreciated.

Open a Command Prompt window and type "java -version"

There's a system property that'll work too if you need to check it from within
an app.

It's no different from Java running on other platforms.

Browser or desktop? (This is an important distinction, since
they are not necessarily the same.)

You can find out which Java (if any) a browser is using by
pointing it here.
<http://www.physci.org/pc/property.jsp?prop=java.version>

OTOH, there is a link to download the 'application' version of that
program (JTest - at the top of the page) that will show that property
(as well as others) for the destop.

But let's clarify browser/desktop first.

Andrew: good point - my friend needs a version of Java installed to enable
certain functions in a browser - is this different than the "runtime Java"
from sun systems?

thanks...

Get your friend to visit this link. If it says '1.1.4',
that will (probably) be the problem.

Possibly, especially if the browser is Internet Explorer, or very old.
Your friend *should* upgrade the browser to Sun Java if it is *not*
using it. While there are other good manufacurers of the Java plug-in,
there are also some bad ones, and it is best (for average end users)
to stick with the one made by Sun.

OTOH, perhpas I should have a closer look at this
"..tutorial for an online registration service.".
What is the URL?

[ If they have been smart, it will work with Java 1.1 +,
and the problem *might* be something other than what I
am guessing (IE missing modern Java) ].

Hello Andrew:

Thanks for the pointers.

When I visit the link above with IE6, it shows nothing. When I visit with
Mozilla Firefox, it says, "Java Version 1.4.2_05." I'm slowly getting the
picture here. M$ seems to have dropped its support for it's "java VM"
environment; therefore, I suppose if my friend wants to do her online
tutorial, she'll need to use a Mozilla-based browser. I did recently
install the latest Sun java runtime on her system (therefore the version
readout above); it's just that I assumed somehow that Sun java would install
its own plugin in IE6.

The registration service is called "regonline"; they don't say much about
their tutorials on their site.

It should NEVER show NOTHING, Cynthia.

It might display
"This page requires 'Java enabled'. Please consult
your browser settings or system administrator."

Or.. "This applet requires the free Java Plug-In."

Which is it?
....M$ seems to have dropped its support for it's "java VM"
environment;

Yes. Now MS supply IE with no Java.
(A lot of browser makers offer 'Java'/'No Java' options)
The user can install Java if they want.
..therefore, I suppose if my friend wants to do her online
tutorial, she'll need to use a Mozilla-based browser.

She can install it for IE's use, or *configure IE* as apporpriate.

But, listen closely.

I am not sure what the problem is yet, and before we go getting
carried away, I want to see this applet for myself.

I could not see any applets at all. Can you copy/paste the
URL (web address) you visit to see this page?

Hi Andrew,

Thanks for your comments. Re, your last comment, I re-affirm that IE6 shows
NOTHING (except a large blank square with a tiny square red "x" in the upper
left - IE's "can't load graphic" icon..) When I use FireFox, I get a
drop-down select, then below a grey square with the info chosen in the
drop-down visible.

I even went into IE6 tools/options and ENABLED all the Java options in
advanced (Java Sun, Java console, Java logging and Java compiler). I then
re-booted the whole system, but the web-link still gave the
"empty/no-graphic" icon described above.

As far as the "regonline" tutorial, I'll have to check with their tech
support to see what they require. Nonetheless, I would like to get IE6
Java-friendly if possible.

That is a warning sign that my earlier guesses were *WRONG*.
There is another thing that might have happened to IE.

Let's test it..
<http://www.physci.org/test/appletcall/index5.html>

This page was designed for something else, but it might
tell me something important. What are the (any) word or
words before "Above is defined an applet call in two
forms, an..."

Are there *any* words *above* that sentence? What are they?
I even went into IE6 tools/options and ENABLED all the Java options in
advanced (Java Sun, Java console, Java logging and Java compiler).

Good. I was about to ask you to go into IE options, but it
seems you're already ahead of me there. We might come back to
those, but it's good to know you are familiar with them.

(snip)
As far as the "regonline" tutorial, I'll have to check with their tech
support to see what they require.

If you could. I always forget to add "..and don't forget to
ask the people who supply this Applet!"
..Nonetheless, I would like to get IE6
Java-friendly if possible.

OK, that answers a question I was about to ask you.
(Are you prepared to simply dump IE and use a different browser?
...Good to see you are not giving in so easily! )
