Help on RTP session!

Actually, i'm currently testing a java program that can send voice through the network but i faced problem on only windows 2000. I had tested on windows 98, windows Xp and windows 2000 locally. But when i send voice over 2 windows 2000 PCs, this error come out - "Cannot create the RTP session: Can't open local data port: 12468". Can anybody tell me what is the error means? Thank you.

Sorry by my english im from spain.
The problem is in the transmiter because he send the stream by the same port that the receiver will go to receive.
I change this code in AVTransmiter2
private String createTransmitter() {
int port,port2;
port2 =portBase - 2*i -2;
localAddr = new SessionAddress( InetAddress.getLocalHost(),port2);
And now you can utilice in the same mahine AVTransmit2 and AVReceive2.
PD: if you want have the sound in mpg archive you must put in AvReceive other sesion with the port + 2.

Help with RTP: Format of Stream not supported in RTP Session Manager

Hello everyone,
I am quite new to JMF and RTP. So far I've succeeded in capturing audio from the microphone and playing it back. However, I failed when I tried to send the stream over using RTP.
Here's my program, all it does is: get a DataSource from the CaptureDevice, create a Processor with that DataSource, convert the tracks in the Processor to one of the RTP formats, and create an RTP SendStream using the Processor's output DataSource.
I can hear sound by creating a Player for the DataSource; however I get errors when I try to create RTP SendStream for the same output DataSource.
Here's my code:
            CaptureDeviceInfo cdinfo;
            Format fmt = new AudioFormat(AudioFormat.LINEAR, 8000, 8, 1);
            Vector deviceList = CaptureDeviceManager.getDeviceList(fmt);
            if (deviceList.size() > 0) {
                System.out.println("Device Found.");
                cdinfo = (CaptureDeviceInfo) deviceList.firstElement();
            } else {
                System.out.println("No device!");
                return;
            DataSource ds = Manager.createDataSource(cdinfo.getLocator());
            Processor processor = Manager.createProcessor(ds);
            StateHelper sh = new StateHelper(processor);
            if (!sh.configure(10000)) {
                System.out.println("Could not configure...");
                System.exit(-1);
            // Get the track control objects
            TrackControl track[] = processor.getTrackControls();
            System.out.println("Number of tracks:" + track.length);
            boolean encodingPossible = false;
            // Go through the tracks and try to program one of them to outout some "RTP format"
            for (int i = 0; i < track.length; i++) {
                try {
                    track.setFormat(new AudioFormat(AudioFormat.DVI_RTP));
encodingPossible = true;
} catch (Exception e) {
// cannot convert
track[i].setEnabled(false);
if (!encodingPossible) {
System.out.println("Could not encode..");
sh.close();
return;
processor.setContentDescriptor(new ContentDescriptor(ContentDescriptor.RAW));
if (!sh.realize(10000)) {
System.out.println("Could not realize...");
System.exit(-1);
System.out.println("Realized...");
DataSource outSource = processor.getDataOutput();
System.out.println(outSource.getContentType());
processor.start();
player = Manager.createRealizedPlayer(outSource);
player.start();
SessionAddress addr = new SessionAddress(InetAddress.getByName("224.144.251.104"), 8194, 4);
manager.initialize(addr);
//manager.addFormat(new AudioFormat(AudioFormat.GSM_RTP), 1);
System.out.println("RTP Session started...");
stream = manager.createSendStream(processor.getDataOutput(), 0);
I get an error on the last line, the error is: javax.media.format.UnsupportedFormatException: Format of Stream not supported in RTP Session Manager And again, if I try to encode the tracks into *AudioFormat.GSM_RTP* instead of *DVI_RTP*, I get a different error on the same line:Exception in thread "AWT-EventQueue-0" java.lang.NullPointerExceptionWell I don't understand what's happening, is there something I need to do before I can use RTP?
Hope you guys help :)

Hi,
seems that you are encoding a track to RTP format but outputting a RAW format.
Your encoding section is also a little bit lazy as you don't check supported formats...
Try this between configured and realized state:
          // Get the tracks from the processor
          TrackControl [] tracks = processor.getTrackControls();
          // Do we have at least one track?
          if (tracks == null || tracks.length < 1)
              return "Couldn't find tracks in processor";
          // Set the output content descriptor to RAW_RTP
          // This will limit the supported formats reported from
          // Track.getSupportedFormats to only valid RTP formats.
          ContentDescriptor cd = new ContentDescriptor(ContentDescriptor.RAW_RTP);
          processor.setContentDescriptor(cd);
          Format supported[];
          Format chosen;
          boolean atLeastOneTrack = false;
          // Program the tracks.
          for (int i = 0; i < tracks.length; i++) {
              Format format = tracks.getFormat();
          log.info("Input format for RTP conversion: " + format);
          if (tracks[i].isEnabled()) {
               supported = tracks[i].getSupportedFormats();
               // We've set the output content to the RAW_RTP.
               // So all the supported formats should work with RTP.
               if (supported.length > 0) {
                    if (supported[i] instanceof VideoFormat) {
                         tracks[i].setEnabled(false);
                         continue;
               else if (supported[i] instanceof AudioFormat) {
                    // set audio format for RTP transmission
                    chosen = new AudioFormat(AudioFormat.DVI_RTP);
                    tracks[i].setFormat(chosen);
                    tracks[i].setEnabled(true);
                    atLeastOneTrack = true;
               else
                    tracks[i].setEnabled(false);
               else
               tracks[i].setEnabled(false);
          else
               tracks[i].setEnabled(false);
          if (!atLeastOneTrack)
          return "Couldn't set any of the tracks to a valid RTP format";
The important thing should be theContentDescriptor cd = new ContentDescriptor(ContentDescriptor.RAW_RTP);part.

NoPlayerException in a RTP session

hi, I'm learning jmf and follow the jmf2_0-guide. However, when I run the following code, it always says "Error:javax.media.NoPlayerException: Cannot find a Player for :rtp://192.168.1.22:8080/jmfstudy/testMedia.avi". 192.168.1.22:8080 is my ip and port. Could anyone help me?Thanks.
String url = "rtp://192.168.1.22:8080/jmfstudy/testMedia.avi";
          MediaLocator mrl = new MediaLocator(url);
          if (mrl == null) {
               System.err.println("Can't build MRL for RTP");
               return false;
          // Create a player for this rtp session
          try {
               player = Manager.createPlayer(mrl);
          } catch (NoPlayerException e) {
               System.err.println("Error:" + e);

               return false;
          }

Thank you. I use Tomcat as my server and when I visit "http://192.168.1.22:8080/jmfstudy/testMedia.avi" my media player startup and play the movie. But it doesn't work in my programme.

The fact that it doesn't know what the format is
might have to do with the problem. I've had similar
problems, and I've traced it back to missing jars and
codecs. Have you tried running the same code locally
without the transmission to see if you player will
even play the file?Already and it works, I used Player to play it and play normally, I try to make it with the diferents codecs of audio and video, but no sucess.

Need help with the session state value items.

I need help with the session state value items.
Trigger is created (on After delete, insert action) on table A.
When insert in table B at least one row, then trigger update value to 'Y'
in table A.
When delete all rows from a table B,, then trigger update value to 'N'
in table A.
In detail report changes are visible, but the trigger replacement value is not set in session value.
How can I implement this?

You'll have to create a process which runs after your database update process that does a query and loads the result into your page item.
For example
SELECT YN_COLUMN
FROM My_TABLE
INTO My_Page_Item
WHERE Key_value = My_Page_Item_Holding_Key_ValueThe DML process will only return key values after updating, such as an ID primary key updated by a sequence in a trigger.
If the value is showing in a report, make sure the report refreshes on reload of the page.

Rtp session problem

HI, Im using a custom data source for jmf to send audio over a RTPManager using javasound for capturing live audio from a microphone and at the same time receiving audio from a RTP session using jmf, the code for the custom data Source is one posted in here a while ago which is working fine the problem is that when I start sending audio the incoming audio stop but the sound is send correctly to the other part, so if a dont send audio I get the audio from the rtp session if I send audio I dont listen the incoming audio, Im only talking of one side of the call because the other part is sending the rtp session by a sip server that is connected to a regular phone line and I dont know exactly how that work I only know that works. anyone know what can be wrong with this? Can it be a buffer problem? Or a blocking device or just a error on the code? Thanks in advance.

Your question doesn't make a whole lot of sense, but I'd assume you've coded something incorrectly.

Cannot create the RTP Session: Can't open local data port

Hi,
I'm trying to connect to two webcams simultaneously in the order:
MediaLocator inputLocator1 = new MediaLocator("rtp://hostname1:8000/video");
MediaLocator inputLocator2 = new MediaLocator("rtp://hostname2:8000/video");
But I get this during the second connection:
Cannot create the RTP Session: Can't open local data port: 8000
And I can't see the video from hostname2.
I did a check via netstat, and it seems that both mycomputer is receiving the video from both hostname1 & hostname2:
TCP mycomputer:3236 hostname1:8000 ESTABLISHED
TCP mycomputer:3264 hostname2:8000 ESTABLISHED
TCP connections to both host were established!! But why can't I see the video of hostname2???? I've thought of 2 possible reasons why I cannot see the video of hostname2:
1. Is this set of local data port maintained by Java? i.e It's not the same as the TCP port 8000 that I see in mycomputer's netstat. If yes, Java has assigned its local data port 8000 to hostname1, so it fails to reassign that port 8000 to hostname2 while hostname1 is still connected. Any other way to fix this apart from changing the portnumber of hostname2?
2. It has to do with the custom.jar? I've read in an article somewhere in the forum that the custom.jar has to be customized (using JFMCustomizer) to receive video from two hosts with the same portnumber. Can someone elaborate the necessary boxes to check in the JFMCustomizer?
Thanks much,
Rach

After all this while, I finally figured out the problem. In my code, I use MediaLocator to code the receiver and the transmitter. E.g.:
MediaLocator inputLocator1 = new MediaLocator("rtp://hostname1:8000/video");
player1 = Manager.createPlayer(inputLocator1)
MediaLocator inputLocator2 = new MediaLocator("rtp://hostname2:8000/video");
player2 = Manager.createPlayer(inputLocator2)
Manager would complain "Cannot create the RTP Session: Can't open local data port: 8000" because port 8000 is already used up by player1, i.e.:
mycomputer:8000 maps to hostname1:8000
mycomputer:8000 cannot re-map to hostname2:8000
To work around this, I'll need to use SessionAddress. SessionAddress provides the flexibility to do an independent local port mapping, e.g.:
mycomputer:5000 maps to hostname1:8000
mycomputer:5002 maps to hostname2:8000

Need help with JSP - Session Bean scenario

Help with jsp session validation

i've build up a page that only users wil 'administrator' as the session is variable can access. if they don't they will be directed to the login page.
However, I'm getting a null pointer exception.
my code is as follows:
<%@ page import="java.io.*"%>
<%
     if (session.getAttribute("id").equals(null) || !(session.getAttribute("id").equals("administrator")))
          response.sendRedirect("adminlogin.htm");
%>
Error Message:

root cause
java.lang.NullPointerException
any pros please help? i know it's something to do with my jsp session validation. thanks in advance.

one more thing, with regrads to the solution evnafets provided. I tried it out on all my pages that requires administrator rights and found that the code only redirects when it's not expecting any parameters. Else, it just display an error message there. Is there a way around this? Or I should let let my end user suffer?

HELP WITH JSF SESSION

I have 2 managed beans: studentBean and circulationBean. when a student logs in, a session for studentBean is created. the question is how can i access that session attribute from the circulationBean? I need it to create an "insert" query for my Circulation table. Student is a foreign key in the circulation table. PLEASE HELP!!

I may misunderstand what you want to do,
however, if you want to create a circulationBean,
create it by yourself without depending on the managed bean mechanizm.
For example:public class StudentBean {
   private CirculationBean cb;
   public CirculationBean getCirculation() {
    return cb;
   public String login() {
    cb = new CirculationBean(someKey);
   }You can access the created circulationBean by using a cascaded EL expression
as #{student.circulation.someProperty}.

IP Helper Service causes Session "" failed to start with the following error: 0xC000000D

I have a Windows 8.1 Pro version. In the event viewer I can see that the error `Session "" failed to start with the following error: 0xC000000D´ is registered every time I boot my laptop.
I am 100% sure that this is related to the IP Helper Service (iphlpsvc) because the error is logged every time I manually restart the service.

Hi,
IP Helper (service name 'iphlpsvc') is apparently designed to improve a Windows PC's support for IPv6 network protocol.
I suggest you try enable the dump collection by copying following words into notepad, saving it as dump.reg and importing it:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\localdumps\iphelper.exe]
"DumpFolder"=hex(2):63,00,3a,00,5c,00,63,00,72,00,61,00,73,00,68,00,64,00,75,\
00,6d,00,70,00,73,00,00,00
"DumpCount"=dword:00000010
"DumpType"=dword:00000001
"CustomDumpFlags"=dword:00000000
Once the error appears again, please find the crashdump file under c:\.

Help with php session variables

I am using Dreamweaver 8 to set up a dynamic app with PHP and
MySQL. I want the code that the user logs in with ('UPN') to be
stored as a session variable so that recordsets on subsequent pages
can be set to display personalised data.
I have set the session variable like this: $_SESSION['UPN'] =
'UPN' (UPN is the name of the form textfield, also set as the
username for logging in)
On the data page, I have called the variable like this:
$query_Recordset1 = ("SELECT pupils.pupilID, pupils.UPN,
pupils.forename, pupils.surname FROM pupils WHERE UPN = '" .
$_SESSION['UPN'] . "'");
The recordset returns nothing- the dynamic table returns ony
the column headings (both as headings and immediately under where
you would expect the data to be).
Can anyone help?
Thanks

Your code assigns the literal string UPN to the session
variable. If
it's coming from POSTed form data, you'd need to do it like:
$_SESSION['UPN'] = $_POST['UPN'];

HELP NEEDED:: variable SESSION is undefine

Guys, help me out; PLEASE. I'm stuck on this for days and am
running out of options.
I have a CFC that checks some session variables for
validation (client login etc), and I have a RemoteObject call to
said CFC.
All my other CFCs that do not reference session variables
work fine; this one bunks right when my CFC checks the session
variables.
I tried webservices, no-go (hell, I couldn't even see the
faultString!!).
I played around with my CF8 server settings and tried
everything.
I tried Ben Forta's blogs (and posted a question there) but
didn't get much help,
HOW CAN I ACCESS A CFC THAT REFERENCES SESSION VARIABLES
WITHOUT CREATING A GET/SET METHOD TO GET/SET THESE SESSION
VARIABLES!!!! (Obvious security risk).

Thank you for your reply John,
Sorry I wasn't clear in my description.
I do -in fact- have a CFC check my client's log-in and return
a true or false, however in subsequent site functionality, it is
the norm to see whether the session has expired or not. From Flex I
am using a RemoteObject call to a CFC; the CFC has the following if
statement:
<cfif IsDefined(SESSION.CLIENT.boolClientLoggedIn)>
<cfif SESSION.CLIENT.boolClientLoggedIn eq "true">
<cfthrow message="Attempting to call fncClientWebSignup
when client is logged in.">
</cfif>
</cfif>
The faultString I get in Flex is 'Variable SESSION is
undefined.'
Also, I did try to change my wrapper from html to cfm and
still no success. Not only that, but I've tried Webservices (which
failed miserably because I couldn't even get the details of the
SOAP fault!!!).
I built a test cfm page that tests my cfcs (instead of Flex
calling them, I had the cfm call the same cfcs) and Session
variables were defined and everything went well.
It so happens that when Flex calls the SAME cfcs, the SESSION
variable is undefined.
I hope this clears up my problem.
