Did JMF do it for you during installation?

Are you new to Java programming - if so have you had a look through the basic Java Tutorials - here

http://java.sun.com/docs/books/tutorial/

JMF is an 'add-on' to the main Java installation, so you need to get that installed / working before you get to JMF

(Please ignore the above if you're already happy with Java -

we'll need more info about what kind of error you're getting if we're to be able to help you

After installing JMF(on win-Xp and win98) the enironment variables are set to the following:

CLASSPATH=.;.;.;C:\PROGRA~1\JMF21~1.1E\lib\sound.jar;C:\PROGRA~1\JMF21~1.1E\lib\jmf.jar;C:\PROGRA~1\JMF21~1.1E\lib;C:\WINDOWS\java\classes;%JMFDIR%\lib\jmf.jar;%JMFDIR%\lib\sound.jar;.;%CLASSPATH%

PATH=%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Rational\ClearQuest;%JMFDIR%\lib;%PATH%

After this I tried running the JMFDiagnostics applet using an appletviewer . I have jdk1.6.0 installed on my m/c.

It gives me the following error:

JMF Diagnostics:

Java 1.1 compliant browser.....Maybe

JMF classes.....Not Found

I also went through JMF troubleshooting n tried the solutions mentioned there but in vain.

I also made sure that the sound.jar and jmf.jar files are in C:\Program Files\Java\jdk1.6.0\jre\lib\ext .

When I run the SimplePlayerApplet code (using appletviewer) given in the tutorials it gives me the following error:

java.lang.NoClassDefinitionFoundError: javax/media/controllerLIstener.

After doing all this JMF doesn run on my m/c.plz help, workin on a colg proj which is due soon.

Please help as i have some assignments to do on it. Thanks!

OK - so are you interested in learning*, or

did you just want me to feel sorry for you?

Note that those are the only two things I

can offer to you.

* It is not very hard, and I estimate that

you will be able to get a more useful and

robust launch using web start, sooner,

than an equivalent web page based

applet.

> would u plz explain it to me.

Sure.

( If you have not tried those examples that I

linked to earlier, please try them to get a feel

for how it works for the end user. )

You create a web start launch file* for the applet,

that contains much of the same information

as the applet element in HTML, to tell it what

jars are needed, and that main class to load.

This launch file should be with file type JNLP

(e.g. 'jmfproject.jnlp'), you simply link to it in

the same way as you might link to the applet

page, and when a user with a web start enabled

computer (a modern Java Plug-In) clicks the

link, it comes onscreen.

* A very simple JNLP for a project might look

something like this (this is adapted from the

first example on the JMF page I linked to)..

<?xml version="1.0" encoding="utf-8"?>

<jnlp spec="1.0"

codebase="http://www.javasaver.com/testjs/jmf/"

href="animplayer.jnlp">

<information>

<title>Animation Player</title>

<vendor>Andrew Thompson</vendor>

</information>

<resources>

<j2se

href="http://java.sun.com/products/autodl/j2se"

version="1.5+"/>

<jar href="animplayer.jar" />

<jar href="jmf.jar" />

</resources>

<application-desc main-class="AnimPlayer">

<argument>anim/2005-11-26.mov</argument>

</application-desc>

</jnlp>

> Unable to load resource: http://www.javasaver.com/testjs/jmf/jmf.jar

Oopps.. my bad. That error was introduced by

me as I was quickly editing two JNLP files

down to the simplest possible single JNLP,

the actual path for that jar (just checked it by

direct fetch) is ..

http://www.javasaver.com/testjs/jmf/lib/jmf.jar

Note however, that I really posted that more to

show how it might be done. Even the path to

the media file (in the arguments) was shortened

to make it ..'prettier' to view on-screen.

If you would like to see that project working, I

recommend trying the 1st link on the JMF

page that I linked to earlier.

But I would like to get to talking about what *your*

application actually needs, as it will need different

paths, and can probably be optimized to make the

download smaller.
