Applet not launching in Netscape on Mac OS X

[Christer Brinchmann]

Hello.
I am trying to get an applet to work on Mac OS X. The version I am
trying this on now is 10.1.5.

On IE (5.1.3), the applet is showing, and everything is fine. On NS
7.1 and 6.2.3 however, nothing happens.

I read on the Apple developer site
(http://developer.apple.com/documentation/Java/Conceptual/Java131Development/index.html)
that os X ships with java 1.3.1, and that it is used to render
applets, without relying on MRJ or anything.

Is there anything I have to configure on the mac in order to get this
working? There is a Java installation present, but the NS acts as if
there isn't.
I am grateful for any tips!

C.

It would be a lot simpler to help you debug your applet
if you supply an URL - which would seem the natural
thing to do for an applet.

Hi.
This problem is not specific to the applet I am working on... I have
tried to view applets on other sites with NS, and the same thing
happens.

I am new to Mac, so is there anything I have to do to enable applets
on NS?
As I said, only IE (which apparently ships with an MRJ) is able to
show applets.

What happens when your try the links here?

You possibly need to _install_ the Java Plug-In, see..
http://www.physci.org/test/java/PlugIn.html

It was written mostly considering the IE JVM,
but it mentions that browsers suppliers are
getting to the point where they offer Java/no-Java
versions..

As I said, only IE (which apparently ships with an MRJ) is able to
show applets.

What is an MRJ?

http://www.physci.org/test/JRE

For all jre versions, the page displays
"This browser supports the Java Version required!
If this message appears in the page, Java is DISABLED..."

And, I have triple- checked that "Enable Java" is checked...

BTW: MRJ is MacOS Runtime for Java

The first of the pages that appear in the
frameset you were looking at - is here..
http://www.physci.org/test/JRE/javaversion10.html

If you look at the source (now ..who's showing off..)
http://www.physci.org/codes/display.jsp?fl=/test/JRE/javaversion10.htm
l

You'll see that what you are getting there is the
'alt' tag. Which suggests, that..
a) The browser understands the Java tag and
b) The browser either does not have a JVM,
or has the JVM disabled.

And, I have triple- checked that "Enable Java" is checked...

Ehh.. go figure.
"Calling all Mac experts"

BTW: MRJ is MacOS Runtime for Java

So.. it stands for Mr. Java? ;-)

The Java support on Mac OS X is the same for all browsers. Are you able to
run applets using Internet Explorer or Safari? Are you able to run a
minimalist applet such as http://segal.org/java/Hello/ ?

A good place to reach Macintosh Java experts is on the MRJ-Dev list:

Some other Macintosh Java resources are listed at http://segal.org/java/

What version of Netscape are you using?

Make sure that you are using Netscape 7+ for Mac OS X. Netscape 4 is
classic mode only and Netscape 6 had some problems with Java if I
recall.

This reminds me that some versions of Netscape for Macintosh report
JavaScript's javaEnabled as false even if Java is enabled. This could cause
a problem if you are calling javaEnabled in the HTML page. Details at:
