I developed a simple JMS connection tester application to test connectivity of remote JMS queue. It is a jar file.
It works perfectly when executing locally on my pc connecting to JBoss instance running on same pc (i.e. localhost). But when I copy same jar file onto the windows test server (Windows Server 2008 R2 Standard) and run it from there, it gives following exception. The JBoss instance (jboss-eap-7.0) in this case is running on another Linux server.
Here is my code below. I have omitted some sensitive values from inclusion (those strings are CAPITALIZED). Moreover all the values are read dynamically from a properties file which I simplified here by hard-coding them directly in the code.
this is the code I run cmd to invoke the jar
java -Dcom.javtech.appia.javatoolkit.middleware.LogPath=./logs -Dcom.javtech.appia.javatoolkit.middleware.LogKeep=0 -Dlog4j.configuration=file:/E:/component/log.properties -cp .component.jar com.gmt.helper.JMSTester
I don't know why this works on my pc but not on the server. I don't think there are any firewall issues. Because I did connect to the queue on a previous occasion. Also there are no connectivity problems either. Pinging the Linux server where JBoss is running through cmd was a success. Please help.

return true;
}
public static void main(String[] args) {
JMSTester.run("jms/queue/QUEUE_ONE");
JMSTester.run("jms/queue/QUEUE_TWO");
}
}
I have also added my pom file. What I do is I create an uber-jar of all dependencies so I could test on the server without many problems.
