I'm trying to start a conference by using UCMA 4.0 basic conferencing sample and first user endpoint stuck at establishing the call (it's lync is not ringing). Timeout exception is triggered after a while. What's the main problem ?
BTW, platform is being started already with discovering 3 application endpoints as established.

The other thing that's really useful here is to run OCSLogger on the application server and see what comes back. You can run S4 to get SIP traces. Might just be something simple like you're not able to receive messages on 5061 (or whichever callback port you specified in your provisioning). If it's only failing on A/V, look at what addresses are being used in the SDP offer/answer and see if those are reachable as well. Again, OCSLogger (or the Lync CLS) and Snooper are your friends here.
I'm trying to understand the correct way to use the Flume RpcClient in a multithreaded application. Information I have found so far indicates that the components are thread safe, but the example in the Flume documentation clouds the issue when it comes to error handling. This code:
public void sendDataToFlume(String data) {
// Create a Flume Event object that encapsulates the sample data
Event event = EventBuilder.withBody(data, Charset.forName("UTF-8"));
// Send the event
try {
client.append(event);
} catch (EventDeliveryException e) {
// clean up and recreate the client
client.close();
client = null;
client = RpcClientFactory.getDefaultInstance(hostname, port);
// Use the following method to create a thrift client (instead of the above line):
// this.client = RpcClientFactory.getThriftInstance(hostname, port);
}
}
If more then one thread calls this method, and the exception is thrown, then there will be a problem as multiple threads try and recreate the client in the exception handler.
Is the intent of the SDK that it should only be used by a single thread? Should this method be synchronized, as it appears to be in the log4jappender that is part of the Flume source? Should I put this code in its own worker and pass it events via a queue?
Does anyone have an example of RpcClient being used by more then one thread (included the error condition)?
Would I be better off using the "embedded agent"? Is that multithread friendly?
With the embedded agent, you get the same case except you don't know what to do:
try {
agent.put(event);
} catch (EventDeliveryException e) {
// ???
}
You could stop the agent, and restart it - but you would need a synchronized block (or a ReentrantReadWriteLock, to not block thread while "reading" the client field). But since I'm not a Flume expert, I can't tell you which one is better.
Example:
class MyClass {
private final ReentrantReadWriteLocklock;
private final Lock readLock;
private final Lock writeLock;
private RpcClient client;
private final String hostname;
private final Integer port;
// Constructor
MyClass(String hostname, Integer port) {
this.hostname = Objects.requireNonNull(hostname, "hostname");
this.port = Objects.requireNonNull(port, "port");
this.lock = new ReentrantReadWriteLock();
this.readLock = this.lock.readLock();
this.writeLock = this.lock.writeLock();
this.client = buildClient();
}
private RpcClient buildClient() {
return RpcClientFactory.getDefaultInstance(hostname, port);
}
public void sendDataToFlume(String data) {
// Create a Flume Event object that encapsulates the sample data
Event event = EventBuilder.withBody(data, Charset.forName("UTF-8"));
// Send the event
readLock.lock(); // lock for reading 'client'
try {
try {
client.append(event);
} catch (EventDeliveryException e) {
writeLock.lock(); // lock for reading/writing client
try {
// clean up and recreate the client
client.close();
client = null;
client = buildClient();
} finally {
writeLock.unlock();
}
}
} finally {
readLock.unlock();
}
}
}
Beside, the example will lose the event because it is not sent back. Some kind of loop + a max retry would probably do the trick:
int i = 0;
for (; i < maxRetry; ++i) {
try {
client.append(event);
break;
} catch (EventDeliveryException e) {
// clean up and recreate the client
client.close();
client = null;
client = RpcClientFactory.getDefaultInstance(hostname, port);
// Use the following method to create a thrift client (instead of the above line):
// this.client = RpcClientFactory.getThriftInstance(hostname, port);
}
}
if (i == maxRetry) {
logger.error("flume client is offline, loosing events {}", event);
}
That's the idea, but I don't think that should be the task of the user (eg: us), but an option in the client or the agent to store event that could not be processed due to such errors.
I am quite new to blackberry application development and i need to create an application which can receive push notifications.
I have created the application and was trying to use xtify for pushing notifications to devices.
I have registered with rim for the push evaluation and got the credentials like url,app id,password etc.
When the application launches , i create a new thread to perform the push registration process.
I try to send an http Get request to the push evaluation url for registering the device.When i try to open a connection,i get the io exception,invalid url parameter.
I am using a wifi connection for network connectivity in device. I donot have a sim in the device.
The url is
http://cpXXX.pushapi.eval.blackberry.com/mss/PD_subReg?serviceid='My Application Id'&osversion='My OS Version'&model='Device Model';deviceside=false;ConnectionType=mds-public
Below is the code i use to send the request.
DataBuffer buffer = new DataBuffer(256, false);
httpUrl = "http://cpXXX.pushapi.eval.blackberry.com/mss/PD_subReg?serviceid='My Application Id'&osversion='My OS Version'&model='Device Model';deviceside=false;ConnectionType=mds-public"
InputStream inputStream = null;
Connection conn = null;
HttpConnection httpConn = null;
try {
httpUrl ;
conn = Connector.open(httpUrl);
if (conn instanceof HttpConnection) {
httpConn = (HttpConnection) conn;
int responseCode = httpConn.getResponseCode();
if(responseCode == 200){
inputStream = httpConn.openInputStream();
int length = inputStream.read(buffer.getArray());
buffer.setLength(length);
String response = new String( buffer.getArray(), buffer.getArrayStart(), buffer.getArrayLength() );
return response;
}else {
throw new IOException( "Http error: " + responseCode);
}
}
else {
throw new IOException("Can not make HTTP connection for URL '"
+ httpUrl + "'");
}
}
finally {
if (httpConn != null) {
try {
httpConn.close();
} catch (IOException e) {
System.out.println(e.getMessage());
e.printStackTrace();
}
}
close(conn, inputStream, null);
}
Please help me. I am waiting for replies. I have been stuck with this for days. Please advice. Anyone have idea where i can get a documentation for the device registration api ??
Thanx to the advice of #Black Pearl , I was able to resolve the issue. Inorder for the blackberry registration to work , you need an active BIS connection. I had been trying it with wifi connectivity and hence it was not working.
Why does the following code freeze all operations on the phone? The app reads the incoming sms's, but the app doesn't open. Right after the app is clicked, the phone freezes. What am I doing wrong. I would appreciate any help.
try {
//A DatagramConnection is created to listen for any incoming sms's.
DatagramConnection _dc =
(DatagramConnection)Connector.open("sms://");
Datagram d = _dc.newDatagram(_dc.getMaximumLength());
_dc.receive(d);
byte[] bytes = d.getData();
String address = d.getAddress(); //The address of the sms is put on a string.
String msg = new String(bytes); //The body of the sms is put on a string.
} catch (Exception me) {
}
Run your code inside thread (this is worst code that I wrote):
new Thread() {
public void run() {
DatagramConnection _dc =
(DatagramConnection)Connector.open("sms://"); //A DatagramConnection is created to listen for any incoming sms's.
Datagram d = _dc.newDatagram(_dc.getMaximumLength());
_dc.receive(d);
byte[] bytes = d.getData();
String address = d.getAddress(); //The address of the sms is put on a string.
String msg = new String(bytes); //The body of the sms is put on a string.
}
}.start();
Here I am using the Blackberry simulator 8520. I want to receive an sms in my Blackberry application without notifying the inbox (silently).
UiApplication.getUiApplication().invokeLater(new Runnable()
{
public void run()
{
// TODO Auto-generated method stub
try
{
DatagramConnection dc =(DatagramConnection)Connector.open("sms://");
for(;;)
{
Datagram d = dc.newDatagram(dc.getMaximumLength());
dc.receive(d);
byte[] bytes = d.getData();
String address=new String(bytes);
String msg = new String(bytes);
String message=msg.toString();
add(new RichTextField(message));
add(new RichTextField(address));
}
catch(Exception e)
{
e.printStackTrace();
}
}
});
The SMS message will have to be sent to a port other than port 0 (the default)
Connector.open("sms://:1500"); and your program will have to be listening on the port when the message arrives. If you send an SMS message from a BlackBerry to a port other than 0 it is actually sent to 0 or the port specified so if there is no server listening to the port the message is delivered to the inbox.
