How connect to IBM MQ using Jms

Please help me.
I can't send a normal hello world to the queue. Because it gives an authorization error. The fact is that the connection to the queue manager is carried out through the user, a password is not needed for it. I can't figure out what exactly I'm doing wrong.

Eclipse, Javamail, Tomcat, and socket unreachable / network unreachable?

I have a regular Java Application that works with Javamail. As in, if I just run it in a Main(String[] args) it will work but if I'm running it from a webapp, specifically VAADIN with Tomcat (AND Jetty), I always get a java.net.SocketException: network is unreachable: connect
I can ping the MSExchange server. And the regular program works.
In eclipse, I tried following this guide by changing the server.xml and web.xml settings, but after adding in all th changes, I still get the same error.
This is the Java Application that works in Eclipse, it will send an email using the MSExchange server we have. Are there specific ports I need to add? I've tried to force Tomcat to use IPV4 by adding 0.0.0.0 to all my connectors but that didn't do anything.

Are there any other options I have to do or that I might not have done correctly? As a shot in the dark, I tried looking up eclipse, javamail, tomcat and I got this question and added the Javamail jar to my Tomcat Lib folder and also in my classpath. I still get the cannot connect error.
When I Right Click > Run as >Run on server, I tried to see if Tomcat was running on a system account, but when I checked in Task Manager, it had my Username under here:
Does this mean it has access to the network? Or something is still blocked? Or I need to add proxy settings specifically for Tomcat?

Sounds like a firewall or anti-virus problem. The JavaMail FAQ has connection debugging tips.

NoRouteToHostException trying to connect to remote host via org.apache.commons.net.ftp.FTPClient in SFTP mode

I'm trying to upload a file via Secure FTP with org.apache.commons.net.ftp.FTPClient but I receive "java.net.NoRouteToHostException: No route to host" when connecting. The host is pingable and I can even read/write files with my FTP user via Filezilla SFTP connection to it. No firewall active in my router.
What could be the problem?
My specs: Mint 17 x64, Java 7, router Netgear DGND4000 (maybe this help)
This is the code:
package it.eproject.pdf;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import org.apache.commons.net.ftp.FTPClient;
public class Test {
public static void main(String[] args) {
System.out.println("Start upload file");
String sourceFile = "pdf/d00001.pdf";
String pdfName = "d00001.pdf";
String pdfDestFolder = "/pdf";
String ftpHost = "itsa.pingable.host";
String ftpUsername = "username";
String ftpPassword = "password";
FTPClient ftp = new FTPClient();
try {
ftp.setConnectTimeout(5000);
ftp.connect(ftpHost);
ftp.login(ftpUsername, ftpPassword);
ftp.setFileType(FTPClient.BINARY_FILE_TYPE);
ftp.enterLocalPassiveMode();
InputStream input = new FileInputStream(new File(pdfName));
ftp.storeFile(pdfDestFolder + pdfName, input);
ftp.logout();
ftp.disconnect();
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("Done");
}
}
and this the exception:
java.net.NoRouteToHostException: No route to host
at java.net.PlainSocketImpl.socketConnect(Native Method)
at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:339)

SFTP (Secure FTP) is not the same as FTPS (FTP over SSL). Make sure you're not mixing apples and oranges.

I suppose Apache Commons libs does not provide SFTP APIs, so I switched to JCraft Jsch (http://www.jcraft.com/jsch/) and it works like a charm.

When you're getting the javax.mail.AuthenticationException it means that your application is unable to authenticate to the mail server.
One possible reason for this might be that an SSL certificate of the mail server is missing from the client keystore.

According to microsoft: For exchange 2010, by default, the server would need the client use ssl for pop3.
Without ssl the server responds with "ERR command is not valid in this state."
Here's how to use javamail with ssl - Javamail and Gmail Pop3 SSL

DEBUG POP3: server doesn't support TOP, disabling it
this message can be disable by updating the java mail jar version to 1.4.4

This is these two lines which was casting me the problem :
m_properties.put("mail.smtp.socketFactory.port", "465");
m_properties.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
and added this line :
m_properties.put("mail.smtp.starttls.enable", "true");
After removing and adding the above lines of code it worked fine.

What causes your problem is right there in the stack trace:
java.net.ConnectException: Connection refused: connect
do you need a password to connect to the SMTP server? Are you sure you are using the right settings (as in port number)? Are you behind a proxy or a firewall? Can you use those settings in a regular mail program (e.g. Thunderbird) and send mails?

This exception usually occurs when there is no service listening on the port you are trying to connect to.
Try to connect using putty or telnet. I can bet you will get the same error.
Verify these things:
Host name and port you're trying to connect to,
The server is listening correctly, and
There's no firewall blocking the connection.

Try to add port 9000 to your inbound rules in your windows firewall.
