I have downloaded and installed the Sun’s JMF, following the instructions there, and performing the setup for linux that i found there.
I’m running kubuntu 5.04, jdk5.03 and every system requirements are fulfilled.
the system variables have been exported using /etc/profile as I did with JAVA_PATH and JAVA_HOME so it should work ???
