Calling Apache http client library underload in webservice - java

I have an issue with my Apache Http Client code. It's a simple hello world method, and another method which calls hello world using the Apache http client code.
I deploy it to webservice and for the first 100 or so in a loop it responds with 20ms fast times. After that is slowly starts going up in response time, if I run it for 3000 requests the response time becomes 150ms, 10000 450ms, etc.. Also the response time never goes back down after long period of in-activity, it only increases.
I have linked this to the method createHttpClient, the b.build method takes longer and longer to build the client for some reason. Is there any way to fix this, or is there a better http API for high long conditions.
My code (not finalized just more of a proof of concept phase right now):
public final class HttpClientTools

java - unit testing for REST request

I have the method:
public HTTPResult get(String url) throws Exception{
try {
ResponseEntity<String> response = restTemplate.getForEntity(url, String.class);
return new HTTPResult(response.getBody(), response.getStatusCode().value());
}
catch (ResourceAccessException e) {
String responseBody = e.getCause().getMessage();
JSONObject obj = new JSONObject(responseBody);
return new HTTPResult(obj.getString("responseBody"), Integer.parseInt(obj.getString("statusCode")));
}
}
I want to do unit testing for it and i am not sure how to proceed:
public class MockHttpServerTest {
private static final int PORT = 51234;
private static final String baseUrl = "http://localhost:" + PORT;
private MockHttpServer server;
private SimpleHttpResponseProvider responseProvider;
private HttpClient client;
#Before
public void setUp() throws Exception {
responseProvider = new SimpleHttpResponseProvider();
server = new MockHttpServer(PORT, responseProvider);
server.start();
client = new DefaultHttpClient();
}
I am getting RED for MockHttpServer & SimpleHttpResponseProvider which should be part of org.apache.wink.client.*; which i am importing. so why do i have red ones? is there some simple way to unit test it?
HTTPResult return me response code and message.

Read rcon command response

I want to send rcon command to server using java, to do this I'm using the following library https://github.com/Kronos666/rkon-core
When i run command like this
Rcon rcon = new Rcon("127.0.0.1", 27015, "mypassword".getBytes());
// Example: On a minecraft server this will list the connected players
String result = rcon.command("list");
// Display the result in the console
System.out.println(result);
My server show response in console Gc connection established from... and so on
but in java app i have the empty result, it's not null, it's just empty
String result = rcon.command("list");
How can i take response from server using rcon protocol?

Try this:
try {
Rcon rcon = new Rcon("127.0.0.1", 27015, "mypassword".getBytes());
String result = rcon.command("list");
System.out.println(result);
} catch (AuthenticationException e) {
String result = "Authentication failed";
}

Finally I write my own implementation:
public final class RconClient implements AutoCloseable {
private static final int MAX_SIZE = 4096;
private final Socket socket;
private final RconData data;
private static final Logger LOG = LoggerFactory.getLogger(RconClient.class);
#SuppressWarnings("ConstructorShouldNotThrowExceptions")
public RconClient(final String host,
final int port,
final byte[] password) throws IOException {
this.socket = new Socket(host, port);
final RconData requst = request(new RconData(RconData.AUTH, password));
if (requst.getId() == -1) {
LOG.error("Wrong password or ip to connect to rcon");
throw new LoginException(host, port);
}
this.data = read();
}
public String command(String command) throws IOException {
command = "get5_status";
final RconData response = request(new RconData(command.getBytes()));
return new String(response.getPayload(), Charset.forName("UTF-8"));
}
public RconData request(RconData packet) throws IOException {
try {
write(packet);
return read();
} catch (final SocketException exception) {
socket.close();
throw exception;
}
}
private void write(RconData packet) throws IOException {
ByteBuffer buffer = ByteBuffer.allocate(packet.getPayload().length + 14);
buffer.order(ByteOrder.LITTLE_ENDIAN);
buffer.putInt(packet.getPayload().length + 10);
buffer.putInt(packet.getId());
buffer.putInt(packet.getType());
buffer.put(packet.getPayload());
buffer.put((byte)0);
buffer.put((byte)0);
socket.getOutputStream().write(buffer.array());
socket.getOutputStream().flush();
}
private RconData read() throws IOException {
byte[] packet = new byte[MAX_SIZE];
int packetSize = this.socket.getInputStream().read(packet);
ByteBuffer buffer = ByteBuffer.wrap(packet, 0, packetSize);
buffer.order(ByteOrder.LITTLE_ENDIAN);
if (buffer.remaining() < 4) {
throw new WrongPacketException();
}
int size = buffer.getInt();
if (buffer.remaining() < size) {
throw new WrongPacketException();
}
int id = buffer.getInt();
int type = buffer.getInt();
byte[] payload = new byte[size - 10];
buffer.get(payload);
buffer.get(new byte[2]);
return new RconData(id, type, payload);
}
#Override
public void close() throws IOException {
this.socket.close();
}
}
Where RconData it's simple POJO with byte[] password property,

java.io.IOException: HTTP request failed, HTTP status: 500 (ksoap2)

I'm using KSOAP2, when sending request to the server and got java.io.IOException: HTTP request failed, HTTP status: 500 in the line httpTransport.call(SOAP_ACTION, envelope) , but server works, I have checked it using SoapUI. What can be the problem?

Make sure your NAMESPACE, METHODNAME, WSDL and SOAP_ACTION are correct.
Try this code,
private static final String NAMESPACE = "http://www.kltro.com";
private static final String METHODNAME = "getUser";
private static final String WSDL = "http://ap.kashkan.org:55555/tro/ws/kltro";

private static String TAG = "soap";
public static String callWebservice() {
String responseDump = "";
try {
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
SoapObject request = new SoapObject(NAMESPACE, METHODNAME);
request.addProperty("login", login);
request.addProperty("pass", password);
request.addProperty("androidID", androidID);
request.addProperty("ver", version);
envelope.bodyOut = request;
HttpTransportSE transport = new HttpTransportSE(WSDL);
transport.debug = true;
try {
transport.call(SOAP_ACTION, envelope);
String requestDump = transport.requestDump;
responseDump = transport.responseDump;
Log.e(TAG, requestDump);
Log.e(TAG, responseDump);
} catch (IOException e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
return responseDump;
}
Also make sure you have internet permission in the manifest,
<uses-permission android:name="android.permission.INTERNET" />

I searched all blog and find same thing but i dont know what am i doing wrong here..
If is there any other way or solution to connect Facebook XMPP then please Help me
ASAP

Finally, thanks to the no.good.at.coding code and the suggestion of harism, I've been able to connect to the Facebook chat. This code is the Mechanism for the Asmack library (the Smack port for Android). For the Smack library is necessary to use the no.good.at.coding mechanism.

To use it:
ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com", 5222);
config.setSASLAuthenticationEnabled(true);
XMPPConnection xmpp = new XMPPConnection(config);
try
{
SASLAuthentication.registerSASLMechanism("X-FACEBOOK-PLATFORM", SASLXFacebookPlatformMechanism.class);
SASLAuthentication.supportSASLMechanism("X-FACEBOOK-PLATFORM", 0);
xmpp.connect();
xmpp.login(apiKey + "|" + sessionKey, sessionSecret, "Application");
}
catch (XMPPException e)
{
xmpp.disconnect();
e.printStackTrace();
}
apiKey is the API key given in the application settings page in Facebook. sessionKey is the second part of the access token. If the token is in this form, AAA|BBB|CCC, the BBB is the session key. sessionSecret is obtained using the old REST API with the method auth.promoteSession. To use it, it's needed to make a Http get to this url:
https://api.facebook.com/method/auth.promoteSession?access_token=yourAccessToken
Despite of the Facebook Chat documentation says that it's needed to use your application secret key, only when I used the key that returned that REST method I was able to make it works. To make that method works, you have to disable the Disable Deprecated Auth Methods option in the Advance tab in your application settings.

I solved this problem. I find solution that http://community.igniterealtime.org/thread/41080

It is then called thus from the JabberSmackAPI:
public void login(String userName, String password) throws XMPPException
{
SASLAuthentication.registerSASLMechanism("DIGEST-MD5",MySASLDigestMD5Mechanism. class);
ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com",5222);
config.setSASLAuthenticationEnabled(true);
config.setRosterLoadedAtLogin (true);
connection = new XMPPConnection(config);
connection.connect();
connection.login(userName, password);
}
