i have found some code but i was not able to understand that
please explain with example your help will be appretiative
jmf.jar (or customized jar) - anywhere, just define its location
.jmfdir file - %windir%\java\.jmfdir - your jmf directory defined here
jmutil.dll, jmsound.dll (jmgsm.dll, 4example, and so...) - %sysdir%\ (System32, 4example) - all necessary dlls, for audioconference you could use this three.
You need also to register: to run JMFInit.class, include it (and needed) to your customized jar-file. Result is correctly placed jmf.properties file. Also you need to commit "Permit record in Applet", and such, if necessary.
