Using a function from another file

Question

Dear friends,
I have two different java files in one folder. One is sm.java and the other is AVTransmit2.java. The code below describes the create Transmitter function in the AVTransmit2.java file. Now if i would like to use this function in sm.java, how do i do it ? The create transmitter function is shown below. Thank You, Gan.P
private String createTransmitter() {
// Cheated. Should have checked the type.
PushBufferDataSource pbds = (PushBufferDataSource)dataOutput;
PushBufferStream pbss[] = pbds.getStreams();
rtpMgrs = new RTPManager[pbss.length];
SessionAddress localAddr, destAddr;
InetAddress ipAddr;
SendStream sendStream;
int port;
SourceDescription srcDesList[];
for (int i = 0; i < pbss.length; i++) {
try {
rtpMgrs = RTPManager.newInstance();
// The local session address will be created on the
// same port as the the target port. This is necessary
// if you use AVTransmit2 in conjunction with JMStudio.
// JMStudio assumes - in a unicast session - that the
// transmitter transmits from the same port it is receiving
// on and sends RTCP Receiver Reports back to this port of
// the transmitting host.
port = portBase + 2*i;
ipAddr = InetAddress.getByName(ipAddress);
localAddr = new SessionAddress(InetAddress.getLocalHost(),
port);
destAddr = new SessionAddress(ipAddr, port);
rtpMgrs.initialize(localAddr);
rtpMgrs.addTarget(destAddr);
System.err.println( "Created RTP session: " + ipAddress + " " + port);
sendStream = rtpMgrs.createSendStream(dataOutput, i);
sendStream.start();
} catch (Exception e) {
return e.getMessage();
return null;
}

Kalani and Bz,
Thanks for the reply. Now i can call the function ,
but when i write sendStream.start(); it indicates
that, its an error. sendStream.start is in that
function. but i cant call that
Any idea ?
