Java Plugin for 1.5.0?

Where is the Java Plugin for 1.5.0?

I've just updated one of my applets to use Java 1.5.0 constructs. It works
fine in the AppletViewer so I decided to put it into a web page and check it
out; I started bringing the HTML for the page up to the 1.5.0 level and was
astonished to find that the newest Java Plugin is apparently 1.4, according
to http://java.sun.com/products/plugin/downloads/index.html.

Am I correct in assuming that Plugin 1.4 will not run code written for Java
1.5? If that's true, then how do I go about using an applet that uses Java
1.5 features?

Or is this a not-very-gentle way of forcing me to use Java Web Start?

I have not done many applets in the past two or three years and have not
been following developments with respect to the applet plugin or Java Web
Start so forgive me if the answer to this question has already been
discussed at some point.

By "plugin", do you mean allowing applets to run in web browsers? E.g.
the "Java" plugin for "Firefox"? If so, then go to this site and select
JRE5.0:

That's right, I want the plugin that I can put into a browser so that it
will display my Applets (actually, JApplets written for Java 1.5.0).

How does that help me? I already have the 1.5.0 JDK.

I had planned to simply update my HTML so that the parameters 'Classid',
'Codebase', etc. pointed to the appropriate URLs and values for Java 1.5.0.
I couldn't find the values I needed for Java 1.5.0 but, in the course of
looking, I found the plugins page that I cited and it didn't seem to have
anything newer than Java 1.4. I'm assuming that the Java 1.4 plugin, even if
I downloaded it and installed it manually, is not going to run a Java 1.5.0
applet - correct me if I'm wrong!

Therefore, I'm asking if someone can point me to the 1.5.0 plugin. I have to
assume that it exists by now - Java 1.5.0 has been out a fair while now -
but perhaps I'm wrong: perhaps Sun didn't upgrade the plugin so that it
could force people to switch to Java Web Start.

Can you or anyone else point me in the right direction?

Is 1.5.0 the minimum Java Version for this code?

According to this..
<http://java.sun.com/j2se/1.5.0/docs/guide/javaws/developersguide/launch.html#creating>
..

..the classid for 1.5 is...
classid="clsid:5852F5ED-8BF4-11D4-A245-0080C6F74284"

??? What does that mean? JWS has been a part of Java since 1.3!

The plugin is included in the JRE, and should be registered in most popular
browsers automatically. You can write a small applet that displays your
java version, and see if it does indeed show 1.5 - or I'm sure an applet
like this already exists on the web somewhere.

If your browser is indeed still using 1.4 try uninstalling 1.4 completely,
and then install 1.5.

Please disregard this question.

After considerable poking around, I found some examples that showed me how
to change my existing HTML to download the Java 1.5.0 plugin. I now have a
HelloWorld applet that demonstrates Java 1.5.0 functionality (a simple
for:each loop) working in my browser. I should be able to figure out how to
get my real applet working now.

I still don't know why Plugin 1.5 is not on the download page but I
obviously went too far in assuming that this meant that the plugin has not
been updated for Java 1.5.0, or that applet developers and users would have
to start using Java Web Start to work with applets. Sorry if I caused anyone
any concern!

Glad you sorted it. ( And if anyone was 'concerned' by
that, they should seek some therapy! ;)
