I'm using nanohttpd in my native java code. When I use it normally everything looks good, but when I use jni library methods it does not work.
my app uses nanohttpd to make stream for mediaPlayer.
native methods:
public native String LH();
public native int P();
public native String EngineGS(Context context);
public native byte[] OGB(byte[] inputBuff);
variables :
private MediaPlayer mp;
private HTTPServer encryptServer;
nanohttpd class:
public class HTTPServer extends NanoHTTPD {
public HTTPServer(int port) throws IOException {
super(port);
start(NanoHTTPD.SOCKET_READ_TIMEOUT, false);
}
#Override
public Response serve(IHTTPSession session) {
Response response = null;
try {
InputStream inputStream = new FileInputStream("/sdcard/Download/" + "encrypted.mp3");
byte[] encryptedInputByteArray = IOUtils.toByteArray(inputStream);
byte[] decryptedByteArray = OGB(encryptedInputByteArray);
inputStream = new ByteArrayInputStream(decryptedByteArray);
int totalLength = inputStream.available();
String requestRange = session.getHeaders().get("range");
if (requestRange == null) {
response = NanoHTTPD.newFixedLengthResponse(Response.Status.OK, "audio/mpeg", inputStream, totalLength);
} else {
Matcher matcher = Pattern.compile("bytes=(\\d+)-(\\d*)").matcher(requestRange);
matcher.find();
long start = 0;
try {
start = Long.parseLong(matcher.group(1));
} catch (Exception e) {
e.printStackTrace();
}
inputStream.skip(start);
long restLength = totalLength - start;
response = NanoHTTPD.newFixedLengthResponse(Response.Status.PARTIAL_CONTENT, "audio/mpeg", inputStream, restLength);
String contentRange = String.format("bytes %d-%d/%d", start, totalLength, totalLength);
response.addHeader("Content-Range", contentRange);
}
} catch (IOException e) {
e.printStackTrace();
}
return response;
}
}
play method:
#ReactMethod
public void play() {
mp.getCurrentPosition();
try {
if (encryptServer == null) {
encryptServer = new HTTPServer(P());
}
Uri uri = Uri.parse(LH() + ":" + encryptServer.getListeningPort());
mp.reset();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
mp.setDataSource(getReactApplicationContext(), uri);
mp.prepare();
mp.start();
} catch (Exception e) {
e.printStackTrace();
}
}
I do not know where the problem is.
Errors:
I think the problem comes from here:
No Content Provider: http://localhost:8080
I want to connect to my Glassfish Server at XX.XX.XX.XX:XXXX which is running on a ubuntu machine on our Server.
I want to send messages and then receive them.
My Receiver looks like this:

try {

}
public void subscribeTopic(String topicName, String userCredentials) {

try {

topicConnection.setClientID(temp);
} catch (UnknownHostException e) {

}
TopicSession topicSession = topicConnection.createTopicSession(false, Session.AUTO_ACKNOWLEDGE);
Topic topic = (Topic) ctx.lookup(topicName);

TopicSubscriber topicSubscriber = topicSession.createDurableSubscriber(topic, userCredentials);
topicSubscriber.setMessageListener(new MyMessageListener());
}
catch(NamingException | JMSException ex)
{
ex.printStackTrace();
}
}
And my Sender looks like this:
public JMS_Topic_Sender(){
init();
}
private void init(){
env.put("java.naming.factory.initial","com.sun.enterprise.naming.SerialInitContextFactory");
env.put("org.omg.CORBA.ORBHost","10.10.32.14");

TopicSession topicSession = topicConnection.createTopicSession(false, Session.AUTO_ACKNOWLEDGE);
Topic topic = (Topic) ctx.lookup(topicName);
topicConnection.start();
TopicPublisher topicPublisher = topicSession.createPublisher(topic);
TextMessage tm = topicSession.createTextMessage(message);

topicSession.close();
topicConnection.stop();
topicConnection.close();
}
} catch (NamingException e) {
e.printStackTrace();
} catch (JMSException e) {
e.printStackTrace();
}
}
I got most of this code from various tutorials online.
Now when I want to do the lookup aka. -> ctx.lookup("myTopicConnectionFactory");
I get all sorts of errors thrown:
INFO: HHH000397: Using ASTQueryTranslatorFactory
org.omg.CORBA.COMM_FAILURE: FEIN: 00410008: Connection abort vmcid: OMG minor code: 8 completed: Maybe
javax.naming.NamingException: Lookup failed for 'myTopicConnectionFactory' in SerialContext ........
My question here is, how do I do the lookup correctly?
My guess is that my Propertys (env) are incorrect and I need to change thouse, but I dont know to what?
Also, it works if i run my Glassfish localy on my own Computers localhost.
When im using localhost as adress and 8080 as port.

I have spent 3 days already googl-ing and stackoverflow-ing.
Has someone seen and fixed this already?
You have to set access rules for registering new user. I have attached here the complete access rules. You can add this by clicking raw in access rules.
[{access,announce,[{allow,[{acl,admin}]}]},
{access,c2s,[{deny,[{acl,blocked}]},{allow,[all]}]},
{access,c2s_shaper,[{none,[{acl,admin}]},{normal,[all]}]},
{access,configure,[{allow,[{acl,admin}]}]},
{access,local,[{allow,[{acl,local}]}]},
{access,max_user_offline_messages,[{5000,[{acl,admin}]},{100,[all]}]},
{access,max_user_sessions,[{10,[all]}]},
{access,mod_register,[{access_from,register_from},{access,register}]},
{access,register,[{allow,[{acl,local}]}]},
{access,muc_create,[{allow,[{acl,local}]}]},
{access,pubsub_createnode,[{allow,[{acl,local}]}]},
{access,register,[{allow,[all]}]},
{access,register_from,[{allow,[all]}]},
{access,s2s_shaper,[{fast,[all]}]},
{access,trusted_network,[{allow,[{acl,loopback}]}]}]
The below code worked for me,
AccountManager accountManager = AccountManager.getInstance(connection);
try {
if (accountManager.supportsAccountCreation()) {
accountManager.sensitiveOperationOverInsecureConnection(true);
accountManager.createAccount("name", "password");
}
} catch (SmackException.NoResponseException e) {
e.printStackTrace();
} catch (XMPPException.XMPPErrorException e) {
e.printStackTrace();
} catch (SmackException.NotConnectedException e) {
e.printStackTrace();

and this is servlet code

Statement s=c.createStatement();
s.executeUpdate("insert into details values('"+id+"','"+name+"''"+contt+"')");
out.print("successfullllll");
} finally {

}
}
please check this out.....
This might work only if you are running an emulator on the same machine as the server. Try to replace locahost by 127.0.0.1.
In your connect() method, I can see that you initialized hs as null then you called setRequestProperty. Try to initialize hs properly before calling its methods.
Hi all please give some basic about ActiveMQ with JMS for novice. And configuration steps also.
We are going to create a console based application using multithreading. So create an java project for console application.
Now follow these steps..........
Add javax.jms.jar, activemq-all-5.3.0.jar, log4j-1.2.15.jar to your project library.
(You can download all of above jar files from http://www.jarfinder.com/ .
create a file naming jndi.properties and paste these following texts .. ( Deatils for jndi.properties just Google it)
# START SNIPPET: jndi
java.naming.factory.initial = org.apache.activemq.jndi.ActiveMQInitialContextFactory
# use the following property to configure the default connector
java.naming.provider.url = tcp://localhost:61616
# use the following property to specify the JNDI name the connection factory
# should appear as.
#connectionFactoryNames = connectionFactory, queueConnectionFactory, topicConnectionFactry
connectionFactoryNames = connectionFactory, queueConnectionFactory, topicConnectionFactry
# register some queues in JNDI using the form
# queue.[jndiName] = [physicalName]
queue.MyQueue = example.MyQueue
# register some topics in JNDI using the form
# topic.[jndiName] = [physicalName]
topic.MyTopic = example.MyTopic
# END SNIPPET: jndi
