What does "Message Catalog Not Found" mean?

I have a MDB running in WebSphere, when it tries to pull a message off an MQ Queue the following exception is thrown:

com.ibm.mq.MQException: Message catalog not found

Any idea how to resolve this?

Since the error message you'll be getting with the message catalog is pretty useless, too, here is a little patch for the mq.jar:

Get jad
Disassemble MQException and MQInternalException (the latter is only necessary because it inherits from MQException; we won't change it).

Add this code to MQException:

    // PATCH New fields
    private final static IntHashMap completionCodes = new IntHashMap ();
    private final static IntHashMap reasonCodes = new IntHashMap ();
    static
    {
        addCodes (completionCodes, "MQCC_");
        addCodes (reasonCodes, "MQRC_");
    }

    /**
     * PATCH Create a map of names for the MQ error codes
     * 
     * @param map
     * @param prefix
     */
    private static void addCodes(IntHashMap map, String prefix)
    {
        Field[] field = MQException.class.getFields();

        try
        {
            for (int i = 0; i < field.length; i++)
            {
                String name = field[i].getName();
                if (name.startsWith(prefix)) 
                {
                    name = name.substring(prefix.length());
                    int value = field[i].getInt(null);
                    map.put (value, name);
                }
            }
        }
        catch (IllegalArgumentException e) {
            throw new RuntimeException (e);
        }
        catch (IllegalAccessException e) {
            throw new RuntimeException (e);
        }
    }

Replace getMessage() with this code:

    // PATCH Complete rewrite
    public String getMessage()
    {
        if(ostrMessage == null) {
            String rc = (String)reasonCodes.get(reasonCode);
            if (rc == null)
                rc = "ReasonCode "+reasonCode;
            String cc = (String)completionCodes.get(completionCode);
            if (cc == null)
                cc = "CompletionCode "+completionCode;

            String message = "MQJE001: "+cc+" "+rc;

            if(msgId == 0)
                ostrMessage = message;
            else {
                String s = msgId+" {0} {1}";
                if (exceptionMessages != null) {
                    s = exceptionMessages.getString(Integer.toString(msgId));
                }
                if(numInserts > 0) {
                    Object as1[] = new String[numInserts];
                    if(numInserts > 0) as1[0] = insert1;
                    if(numInserts > 1) as1[1] = insert2;
                    s = MessageFormat.format(s, as1);
                }

                ostrMessage = message+"\n"+s;
            }

            if (underlyingException != null)
                ostrMessage = ostrMessage + "\n" + underlyingException.getMessage();
        }

        return ostrMessage;
    }

Either compile these two classes into a new jar or patch the original mq.jar.

Instead of the MQJE001: RC 2 CC 2035, you'll get "MQJE001: FAILED NOT_AUTHORIZED"

It turns out that this error was thrown because I had the Queue Connection Factory defined at server level (on the WebSphere v6 server) and the wrong classloader was being used to load the above mentioned properties file.

I solved the issue by redefining factory at cell level.
