I have written a java "Queue Cleaner" application in WSAD 5.0 on a Windows 2000 box to remove un-processed messages from a reply queue. I have MQ 5.3 on my Windows box - I tested the app and it works fine. However, when I deploy the class on to my Red Hat Linux AS 2.1 box, it blows up with:
java.lang.NoClassDefFoundError: com/ibm/mq/MQException
I have set my $PATH equal to the following:
bash: /opt/IBMJava2-:/usr/X11R6/bin:
/usr131/jre/bin:/usr/local/bin:/bin:/usr/bin
/local/netscape:/home/brian/bin:/usr/local/netscape:
/opt/mqm/java/lib/com.ibm.mq.jar:
/opt/mqm/java/lib/connector.jar:
/opt/mqm/java/lib/jta.jar:
/opt/IBMJava2-131/bin: No such file or directory
I am assuming that the JVM should be able to track down com.ibm.mq.jar, but obviously not. Am I missing something in the Linux setup for MQ?
Thank You. |

Why are you putting .jar files on your $PATH, when java will look for them on your $CLASSPATH?

| Because PATH is concatenated in the CLASSPATH variable |

| echo your CLASSPATH and see if MQ jar files are present in the CLASSPATH or not. NoClassDefFoundError is always because of CLASSPATH problem. Your CLASSPATH is not right. |

Here is my $CLASSPATH:
/opt/mqm/java/lib/com.ibm.mq.jar:
.:
/opt/mqm/java/lib/connector.jar:
/opt/mqm/java/lib/jta.jar:
/opt/mqm/java:
/opt/mqm/java/lib/:
/opt/mqm/java/lib/libmqjbnd05.so |

Are the jar files really there in that location?
How are you running this app? Are you running this app under WSAD?
Are you running this app under a different user? |

Yes. MQ 5.3 is installed on this machine and all of the jars are in /opt/mqm/java/lib. I am not using WSAD on this box - I developed the app using WSAD on a Windows machine and exported the class file to Linux. Therefore, I'm executing the program using:
java QueueCleaner QMnger Queue
Breaking News: Now the the JVM seems to be able to find the jar files but it is blowing up with:
Exception in thread "main" java.lang.UnsatisfiedLinkError: no mqjbnd05 (libmqjnd05.so) in java.library.path
As you can see from my $CLASSPATH, I've included the libmqjbnd05.so, but it's complaining about the following:
java.util.zip.ZipException: error in opening zip file
at java.util.zip.ZipFile.open(Native Method)
at java.util.zip.ZipFile.<init>(ZipFile.java:127) |

Have you set the environment variable LD_LIBRARY_PATH
Set it to LD_LIBRARY_PATH=install_dir/mqm/java/lib
In your case it should be
LD_LIBRARY_PATH=/opt/mqm/java/lib

You're definitley getting me closer Venny. Here is what happened:

MQJE001: Completion Code 2, Reason 2035
I wonder if it's because I have libmqjbnd05.so in my CLASSPATH? |

AFAIK this shouldn't matter.
2035 means you have authorities problem. If you do dspmqaut on the MQ object you will know whether or not you have the right authorities.
| Code: |
| Usage: dspmqaut [-m QMgrName] [-n ObjName] -t ObjType [-p Principal | -g Group] |
If your user-id is abcd then
dspmqaut -m QMnger -t qmgr -p abcd
If you want to set authorities
setmqaut -m QMnger -t qmgr -p qbcd +all
Similarly for the queue
setmqaut -m QMnger -n Queue -t queue -p abcd +all
It should be OK for testing purposes to give full authorities to the MQ objects.
