Hi,
I just have to test connection to Q-manager using java.
Here is the code I took from the net and try to use updated options for MQQueue.
Here is the code:
| Code: |
# cat MQSample.java
import com.ibm.mq.*;
public class MQSample
{
private String qManager = "your_Q_manager";
private MQQueueManager qMgr;
public static void main(String args[]) {
new MQSample();
}
public MQSample() {
try {
qMgr = new MQQueueManager(qManager);
int openOptions = CMQC.MQOO_BROWSE ; // CMQC.MQOO_INPUT_AS_Q_DEF |
//CMQC.MQOO_OUTPUT ;
MQQueue system_default_local_queue =
qMgr.accessQueue("SYSTEM.DEFAULT.LOCAL.QUEUE",
openOptions);
MQMessage hello_world = new MQMessage();
hello_world.writeUTF("Hello World!");
MQPutMessageOptions pmo = new MQPutMessageOptions();
system_default_local_queue.put(hello_world,pmo);
MQMessage retrievedMessage = new MQMessage();
retrievedMessage.messageId = hello_world.messageId;
MQGetMessageOptions gmo = new MQGetMessageOptions();
system_default_local_queue.get(retrievedMessage, gmo);
String msgText = retrievedMessage.readUTF();
System.out.println("The message is: " + msgText);
system_default_local_queue.close();
qMgr.disconnect();
}
catch (MQException ex)
{
System.out.println("A WebSphere MQ error occurred : Completion code " +
ex.completionCode + " Reason code " + ex.reasonCode);
}
catch (java.io.IOException ex)
{
System.out.println("An error occurred whilst writing to the message buffer: " + ex);
}
}
} |
That is the error I get when I compile:
| Code: |
# javac MQSample.java
MQSample.java:23: cannot find symbol
symbol : variable CMQC
location: class MQSample
int openOptions = CMQC.MQOO_BROWSE ;
^
1 error |
That what I have installed:
| Code: |
# rpm -aq | grep -i mq
MQSeriesClient-7.0.1-3.i386
MQSeriesKeyMan-7.0.1-3.i386
MQSeriesFTA-7.0.1-3.i386

I thought you understood java? Seems like you are missing jars on your classpath, or that one of your import statements may need to be changed...
Have fun

I followed the instruction to set it up.
| Code: |
# echo $CLASSPATH
/opt/mqm/java/lib/com.ibm.mq.jar:/opt/mqm/java/lib/connector.jar:/opt/mqm/java/lib |
| Code: |
ls /opt/mqm/java/lib/
CL3Export.jar com.ibm.mq.jmqi.jar dhbcore.jar libmqjbnd.so
CL3Nonexport.jar com.ibm.mqjms.jar fscontext.jar libmqjexitstub02.so
com.ibm.mq.axis2.jar com.ibm.mq.jms.Nojndi.jar jca libPgmIpLayer.so
com.ibm.mq.commonservices.jar com.ibm.mq.pcf.jar jdbc OSGi
com.ibm.mq.defaultconfig.jar com.ibm.mq.postcard.jar jms.jar providerutil.jar

So what? you are still missing a jar on your classpath.
To find out which you can try a jar -tvf of the different jar files and see where you find MQConstants ??

No jar file has that string. Should I add every single jar file in the class path and then try?
Is this because this package is from IBM and its trial version ? |

Sounds like your best idea so far

the call:
| Code: |
| int openOptions = CMQC.MQOO_BROWSE ; |
| Code: |
The error:
]# javac MQSample.java
MQSample.java:21: cannot find symbol
symbol : variable CMQC
location: class MQSample
int openOptions = CMQC.MQOO_BROWSE ; // CMQC.MQOO_INPUT_AS_Q_DEF |
^
1 error
|
What Is not so reasonable here is, I found that call "CMQC.MQOO_BROWSE" from the documents which came with this whole software package.
Out of all sciences comp-science sucks the most. |

| Add an *explicit* import for com.ibm.mq.constants.CMQC. |

ok It compiles fine now.
but when I run it I get following error.
| Code: |
# java MQSample
MQJE001: Completion Code '2', Reason '2495'.
A WebSphere MQ error occurred : Completion code 2 Reason code 2495
|
Plus is there any javac compiler options to get detailed debug information? |

Thanks but I figured it out.
After setting up
| Code: |
| export LD_LIBRARY_PATH=/opt/mqm/java/lib/ |
that error went away.. 
Now I am getting
| Code: |
| MQJE001: Completion Code '2', Reason '2058' |
