The code given below is not sending RTP packets using JMF.
can any one suggest how can i enable below code for sending RTP
Packets.

How do you know that RTP packets are not being sent?

Capturing audio and communicating with a computer which does not have
the address of the computer from which the applet originated are
privileged actions and are denied by the default security policy.

See http://java.sun.com/sfaq/

You can grant an applet these privileges if you digitally sign it.

Are there any exceptions on the Java console? (If you are using IE I
think it is Tools -> Sun Java Console)

No..., I didn't got any exception at console

Thanks

"Is that a question?"

Search the group on that phrase for a protracted
discussion on English usage, and communicating a
question to people. It might help you in future.

Assuming it is a question.

Perhaps, perhaps not. JMF and applets
do not mix well. Even after the matter of the
applet being signed and 'trusted' by the end client,
there is also an option to 'allow capture from applets'
that is by default *disabled* in JMF installations.

Do you have an URL for this applet (working
or otherwise)? I might be able to determine
more by looking at the output, and playing
with the options of my local JMF installation.

(and ..mostly to irritate Roedy)
Note that sentences in English usually end with a
single full stop (.). After the full-stop, the next letter
should always be Upper Case, since it is the start of
a new sentence. Using full-stops as people expect
to see them, followed by the obligatory Capital at
the start of the next sentecce, helps people to quickly
scan the text of a message, looking for important
points.
(OK.. no, I put that more in the hope it will help
you in future - could not resist the jab at Roedy,
though - see the thread mentioned above, for the
reasons why.)

Thanks for reply and in future I will follow your guide line for
posting any message,
Do you have an URL for this applet

No, I don't have url for this applet

Thanks

That is unfortunate.

Why? Is it because this applet..
1) Is a private applet, not availabe to the
general public, or ..
2) It has just not been uploaded *yet*. Or..
3) Something else?

The reason I ask is that I am still not clear on
whether you might be able to give us an URL
to the applet, at some time in the *future*.

In future applet will be for public.

Great. Please get let to us know when it is
available. Not so much for 'public' as at least
for 'testing'.

It might be possible someone can solve the
problem in the meantime, but I really doubt it.
Having the applet on-screen can be a real
help in solving problems.

BTW. Are you aware of 'web start' or JWS?
I am not sure if I've ever mentioned it to you,
but it is a much better way to launch JMF
based projects (gets around most of the
'applet' problems we have talked about in
this thread).

Yes I am using JWS.
