Error running simple jar with MQ classes for Java

Question

I'm very beginner of Websphere MQ classes for Java programming.
I've decided to follow this way to write a small application able to connect and read messages from a queue through TCP/IP.

following this guide: http://publib.boulder.ibm.com/infocenter/wmqv7/v7r0/index.jsp?topic=%2Fcom.ibm.mq.csqzaw.doc%2Fja10410_.htm

At point 4 it is suggested to test Websphere Client installation (Version: 7.0.1.8) on windows command prompt using:
java -Djava.library.path=library_path MQIVP
where 'library_path' for me is "C:\\Program Files\\IBM\\WebSphere MQ\\java\\lib"

The application runs and I have proceeded writing a simple program with Eclipse IDE here the code:

import com.ibm.mq.MQEnvironment;

public class MQtestMain {

    public static void main(String[] args) {

        System.out.println("main");

        new MQtestMain();
    }

    public MQtestMain(){

        System.out.println("MQtestMain");

        MQEnvironment.hostname = "my.host.name";
        MQEnvironment.channel = "my.channel";
        MQEnvironment.port = 1414;

    }

}

It has nothing to do but it is just a test to be sure that everything is correctly set.

I have set a custom library with both 'com.ibm.mq.jar' and 'com.ibm.mq.jmqi.jar' from "C:\\Program Files\\IBM\\WebSphere MQ\\java\\lib" and no error are reported at compile time.

Running the application from Eclipse it correctly prints out "main" and "MQtestMain" on console.

Therefore I have proceeded to export it: File > Export > Runnable Jar
setting 'Library handling' to 'Package required libraries into generated JAR'

Unfortunately if I run the program from windows command prompt: java -jar MQtest.jar here the result:

main
MQtestMain

First and second line are correct but I really don't understand the following errors

update:

I try to give you more information:
As I've said running the application from its main class file there are no problems, while execute it from the jar file it seems not able to find the IBM libraries.
I have created a personal library in eclipse named "MQ classes for Java" containig the two jar packages used by this application.
here the content of the project .classpath file:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="src" path="src"/>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.7"/>
    <classpathentry kind="con" path="org.eclipse.jdt.USER_LIBRARY/MQ classes for Java"/>
    <classpathentry kind="output" path="bin"/>
</classpath>

Is there a way to link the correct libraries to the runnable jar in order to launch it form every machine with WMQ Client installed?

Solution:

The errors, due to some dependencies not found, have been solved including all the IBM classes for Java jar files into the WMQ Client folder instalation ("C:\\Program Files\\IBM\\WebSphere MQ\\java\\lib")

Answer 1

您需要像使用MQIVP测试一样使用java.library.path，或者将CLASSPATH设置为包含MQ JAR文件。

Answer 2

Solution:

These errors are due to some dependencies not found;
they could be solved including all the IBM classes for Java jar files into the WMQ Client folder instalation ("C:\\Program Files\\IBM\\WebSphere MQ\\java\\lib")

Answer 3

I resolved this just by adding javax dependency:

<dependency>
    <groupId>javax.resource</groupId>
    <artifactId>connector-api</artifactId>
    <version>1.5</version>
</dependency>
