Hi,

short and simple question:
How can i check properly if the Java Media Framework ist installed on
the Computer?

Scenario;
We have a application which has the abbility to show small movies
inside if the JMF is installed. We do not want to ship the JMF with our
application. Currently we are trying to invoke a Class/Method from the
JMF and if there is a ClassNotFoundException we assume that there ist
no JMF installed. No the best way..... ;-)

I've searched a bit and i didn't found a good solution.. Does anybody
know a proper solution for this?

Thanks and beste regards.

Carsten

The makers of JMF use this applet ..
<http://java.sun.com/products/java-media/jmf/2.1.1/jmfdiagnostics.html>
..source is linked from the page.

I didn't check the source, but I suspect they are doing much
the same as what you've already done.

I don't suppose you stumbled across the forum that specialises
in the JMF in your searching? It can be found here..

I tried downloading from the link just now (2006-07-13-14:19 EST), and I
got a zip with the .class file and the .java source code. Try downloading it
again? Or try downloading it from another computer?

I got a zip file that contained both classes and source.

LOL! I've given up trying to analyse these little eccentricities
with browsers and HTTP. ;-)
