Hello,
I have a mpeg player based on JMF, which runs well as a standalong
application under linux using the Linux Performance pack. However, it
fails when I tried to run it through web start. It looks like WS cannot
load the native libraries properly. I got error message claiming the
"com.sun.media.codec.video.jmpx.Jmpx" cannot be found. Following are the
JNLP file, corresponding error message, and source codes. Can anyone help?
thanks a lot.
