im following this documentation to achieve gcm upstream message.
so far,i've created a servlet,and from that servlet im calling the SmackCcsClient.
ConnectionConfiguration config =
new ConnectionConfiguration(GCM_SERVER, GCM_PORT);
config.setSecurityMode(SecurityMode.enabled);
config.setReconnectionAllowed(true);
config.setRosterLoadedAtLogin(false);
config.setSendPresence(false);
config.setSocketFactory(SSLSocketFactory.getDefault());
connection = new XMPPTCPConnection(config);
connection.connect();
connection.addConnectionListener(new LoggingConnectionListener());
// Handle incoming packets
connection.addPacketListener(new PacketListener() {
@Override
public void processPacket(Packet packet) {
logger.log(Level.INFO, "Received: " + packet.toXML());
Message incomingMessage = (Message) packet;
GcmPacketExtension gcmPacket =
(GcmPacketExtension) incomingMessage.
getExtension(GCM_NAMESPACE);
String json = gcmPacket.getJson();
try {
@SuppressWarnings("unchecked")
Map<String, Object> jsonObject =
(Map<String, Object>) JSONValue.
parseWithException(json);
// present for "ack"/"nack", null otherwise
Object messageType = jsonObject.get("message_type");
if (messageType == null) {
// Normal upstream data message
handleUpstreamMessage(jsonObject);
// Send ACK to CCS
String messageId = (String) jsonObject.get("message_id");
String from = (String) jsonObject.get("from");
String ack = createJsonAck(from, messageId);
send(ack);
} else if ("ack".equals(messageType.toString())) {
// Process Ack
handleAckReceipt(jsonObject);
} else if ("nack".equals(messageType.toString())) {
// Process Nack
handleNackReceipt(jsonObject);
} else if ("control".equals(messageType.toString())) {
// Process control message
handleControlMessage(jsonObject);
} else {
logger.log(Level.WARNING,
"Unrecognized message type (%s)",
messageType.toString());
}
} catch (ParseException e) {
logger.log(Level.SEVERE, "Error parsing JSON " + json, e);
} catch (Exception e) {
logger.log(Level.SEVERE, "Failed to process packet", e);
}
}
}, new PacketTypeFilter(Message.class));
// Log all outgoing packets
connection.addPacketInterceptor(new PacketInterceptor() {
@Override
public void interceptPacket(Packet packet) {
logger.log(Level.INFO, "Sent: {0}", packet.toXML());
}
}, new PacketTypeFilter(Message.class));
connection.login(senderId + "@gcm.googleapis.com", apiKey);
its compiling and i dont get any errors as i have included the smack 4.0.7 library.but while executing,im always getting the following error: java.lang.ClassNotFoundException: org.jivesoftware.smack.XMPPConnection
the jar has been added in the build path.
The smack.jar
contains the class. download and add it to your classpath.
