Hostname problem with Wildfly 10 and RabbitMQ JDNI configuration

I'm following this documentation to configure JNDI for Wildfly 10 with RabbitMQ
https://www.rabbitmq.com/jms-client.html
The reason i'm using JNDI is to my application has no dependency with any JMS Provider's library. It means, in my application, i use javax.jms-api-2.0.jar only for integration with RabbitMQ or ActiveMQ... later.
This is my configuration in Wildfly standalone.xml file.
<object-factory name="java:global/jms/ConnectionFactory1" module="com.rabbitmq.jms"
class="com.rabbitmq.jms.admin.RMQObjectFactory">
<environment>
<property name="className" value="javax.jms.ConnectionFactory"/>
<property name="virtualHost" value="/"/>
<property name="host" value="rabbitmq_server"/>
<property name="port" value="5672"/>
</environment>
</object-factory>
This is the soure code for integration.
Context context = new InitialContext();
ConnectionFactory connectionFactory
= (ConnectionFactory) context.lookup("java:global/jms/ConnectionFactory1");
if (connectionFactory == null) {
System.out.println("Cannot initiallize connection factory.");
return;
}
Connection connection = connectionFactory.createConnection(
"guest",
"guest");
if (connection == null) {
System.out.println("Initiallize connection failed.");
return;
}
Session session = connection.createSession(false, QueueSession.AUTO_ACKNOWLEDGE);
if (session == null) {
System.out.println("Initiallize session failed.");
return;
}
My problem is:
At this configuration,
If i set the value is IP address => it is ok
If I set the value is hostname (already mapping with IP address in my hosts file) => it always create connection to localhost.
Anyone has faced with this issue before?

Ya, i just found out that the hostname cannot contains some special character such as _.
Then i removed this from rabbitmq_server to rabbitmqserver then everything is good now.
Hope someone get the issue like me can fix it follow this.

Download file from a remote server with Rest API using JAX RS

I need to download file from a remote server using JAX RS and this is my code:
package rest;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.ResponseBuilder;
#Path("/restwb")
public class FileResource {
#GET
#Path("/{companyName}/{Type}/{cl}/{fname}")
#Produces(MediaType.APPLICATION_OCTET_STREAM)
public Response downloadFile(#PathParam("fname") String fileName, #PathParam("companyName") String CompName,
#PathParam("Type") String Type, #PathParam("cl") String cl) throws FileNotFoundException {
Response response = null;
try {
File file = new File(getClass().getClassLoader()
.getResource(CompName + "/" + Type + "/" + cl + "/" + fileName + ".png").getFile());
FileInputStream inputStream = new FileInputStream(file);
ResponseBuilder rb = Response.ok(inputStream);
rb.header("Content-Disposition", "attachment; filename=" + file.getName());
response = rb.build();
} catch (Exception e) {
e.printStackTrace();
}
return response;
}
}

JMS + Wildfly 8.2.0 Final: The following keys are invalid for configuring a connector: http-upgrade-endpoint

I'm trying to use JMS on Wildfly 8.2.0.
I created one queue called GrinderRemoteQueue with jndi name java:jboss/exported/jms/queue/grinderRemote, using the default Remote Connection Factory. Below there is the section of standalone-full.xml config file for jms configuration.

For test this configuration I created a new Dynamic Web Project in Eclipse Luna, using the following class:
import java.util.Properties;
import javax.jms.Connection;

import javax.jms.JMSContext;
import javax.jms.JMSException;
import javax.jms.MessageConsumer;

import javax.naming.InitialContext;
import javax.naming.NamingException;
import org.hornetq.jms.client.HornetQConnectionFactory;
public class TestJMS {
public void Test() throws NamingException, JMSException {
HornetQConnectionFactory connectionFactory = null;
Connection connection = null;
Session session = null;
MessageProducer producer = null;
MessageConsumer consumer = null;
Destination destination = null;
TextMessage message = null;

try {
final Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
env.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
env.put(Context.PROVIDER_URL, "http-remoting://localhost:8080");
env.put(Context.SECURITY_PRINCIPAL, "jmsuser");
env.put(Context.SECURITY_CREDENTIALS, "*********");
context = new InitialContext(env);
connectionFactory = (HornetQConnectionFactory) context.lookup("jms/RemoteConnectionFactory");
System.out.println("lookup: jms/GrinderRemoteConnectionFactory success!");
destination = (Destination) context.lookup("jms/queue/grinderRemote");
System.out.println("lookup: java:/jms/queue/grinderRemote success!");
JMSContext createContext = connectionFactory.createContext("jmsuser", "Logitech550!", JMSContext.AUTO_ACKNOWLEDGE);
System.out.println("connectionFactory.createContext success!");
createContext.createConsumer(destination);
System.out.println("createContext.createConsumer success!");
connection = connectionFactory.createConnection("jmsuser", "your password");
System.out.println("connectionFactory.createConnection success!");
session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
producer = session.createProducer(destination);
System.out.println("session.createProducer success!");
connection.start();
int count = Integer.parseInt("1");
String content = "Hello, World!";
// Send the specified number of messages
for (int i = 0; i < count; i++) {
message = session.createTextMessage(content);
producer.send(message);
System.out.println("Message sent successfully: " + message);
}
} catch (Exception e) {
e.printStackTrace();
} finally {
if (context != null) {
context.close();
}
// closing the connection takes care of the session, producer, and consumer
if (connection != null) {
connection.close();
}
}
}
}
Running this class I got this output:

I think that the main problem is java.lang.IllegalStateException: The following keys are invalid for configuring a connector: http-upgrade-endpoint, but I can't understand where I'm wrong.
Thanks in advance for replies.

Update all libraries on your client to use wildfly libraries but not jbossAS'
-hornet (module)
-jboss-client (it's at bin/client directory)
-remoting (module)
-etc (module)

Invoking servlet from java

I'm trying to write a java class named Sender.java that invoke a servlet.
This is the code for Sender.java :
public class Sender {
public static void main(String args[]){
try{
URL gwtServlet = new URL("http://localhost/FileReceiver/Receiver");
HttpURLConnection servletConnection = (HttpURLConnection) gwtServlet.openConnection();
servletConnection.setRequestMethod("POST");
servletConnection.setDoOutput(true);
servletConnection.setDoInput(true);
servletConnection.setUseCaches(false);
servletConnection.setDefaultUseCaches (false);
OutputStream os = servletConnection.getOutputStream();
ObjectOutputStream out = new ObjectOutputStream(os);
out.writeInt(1);
out.flush();
out.close();
}
catch (Exception e) {
e.printStackTrace();
}
}
}
and here the code for the servlet Receiver.java :
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request,response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
try {
InputStream is = request.getInputStream();
//until here is ok
ObjectInputStream ois = new ObjectInputStream(is);
int p = ois.readInt();
writer.println("the number p is : " + p);
ois.close();
} catch (Exception exc) {
exc.printStackTrace();
}
}
When I try to run on server (WildFly 8.x) the servlet, I have this error:

I got that the problem is about InputStream is = request.getInputStream(); because I can see this from the debugger (is is null) but I don't know why this happens.
Can someone help me? thank you in advance.

If you want to do an HTTP POST from a Java client to a Servlet, the following requirement must be met:
The Content-Type header must be application/x-www-form-urlencoded. This is usually the default. If you want to send file data or any relevant data stream set your Content-Type to multipart/form-data. This requires the information sent to conform to RFC2388.
Values sent from the connection OutputStream to the Servlet must be an encoded (application/x-www-form-urlencoded) key/value pair (separated by a &).
The Content-Length header must be the length of the encoded value mentioned in 2 or the length of all data that you're willing to send to the server/servlet.
On the Servlet side, you can use request.getParameter() method (passing the parameter key) to obtain its value. For multipart/form-data, you can then use request.getInputStream().
I hope this helps. A brilliant example, written by BalusC on StackOverflow, on how to fire HTTP POST in Java can be found here.

Email sending in a Java Webapplication

I'm writing a webapp in Java. In this webapp I will send emails to the users. When I execute the application I get an error message. I use the same source code in another Java program. In that program I get no errors.
Source code:
public class MailUtil {
public static Session getGMailSession(String user, String pass){
final Properties props = new Properties();
//Eigenschaften zum Sende einer Mail mit GMail
props.setProperty("mail.smtp.host", "smtp.gmail.com");

props.setProperty("mail.smtp.port", "465");
props.setProperty("mail.smtp.socketFactory.port", "465");
props.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.setProperty("mail.smtp.socketFactory.fallback", "false");
return Session.getInstance(props, new javax.mail.Authenticator(){
#Override protected PasswordAuthentication getPasswordAuthentication(){
return new PasswordAuthentication (props.getProperty("mail.pop3.user"),props.getProperty("mail.pop3.password"));
}//endof Methode getPasswordAuthentication
});//endOf getInstance
}//endOf Methode getGMailSession
//Die Methode postMail versendet eine Mail
public static void postMail(String recipient, String subject, String message){
Session session = MailUtil.getGMailSession("user", "password");
try{
Message msg = new MimeMessage(session);
msg.setSubject(subject);
msg.setContent(message, "text/plain");
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(recipient));
Transport.send(msg);
}
catch(MessagingException e){
System.out.println("Error in this Method");
System.out.println("Cause: " +e.getMessage());
e.printStackTrace();
}
}
}

You have missed the ,
msg.setFrom(username);
method ,which should be configured to send the email from your account.
As docs says.
Set the "From" attribute in this Message. The value of this attribute
is obtained from the property "mail.user". If this property is absent,
the system property "user.name" is used.
And also read this thread JavaMail API, Gmail-Auth and setFrom

First, fix all of these common mistakes.
Second, read this JavaMail FAQ entry on Gmail.
If you still can't get it to work and are getting the same error, tell us what debugging you've done to prove that you're specifying a user name when connecting. You might want to look at these debugging tips.
