Welcome to the Ranch.
In future, please do not ask the same question multiple times. I have deleted your duplicate topic.
From the page link you posted,
If you are installing the JMF Performance Pack for Linux
Change directories to the install location.
Run the command % /bin/sh ./jmf-2_1_1e-linux-i586.bin
Did you run this?
Instead of the installer, you might want to consider unzipping
If you are installing a zip file
Run the appropriate zip command for your system, e.g. winzip or unzip to extract JMF onto your system.
Once you have successfully installed you will need to
Eclipse->Project Properties->Java Build Path->(libraries tab)->Add external jars->Select " jmf.jar" (this should be somewhere in your installation directory
