I am trying to get the Q time of a queue using NS0B.
My java program is a modification of the PCFMessageListQueueDepth.java example
The request code is like
request = new PCFMessage (CMQCFC.MQCMD_INQUIRE_Q_STATUS);
request.addParameter (CMQC.MQCA_Q_NAME, "Bug");
request.addParameter (CMQCFC.MQIACF_Q_STATUS_ATTRS, CMQCFC.MQIACF_ALL);
To display the result, I have
// Display the results
for (int i = 0; i < responses.length; i++)
{
String name = responses [i].getStringParameterValue (CMQC.MQCA_Q_NAME);
String pdate = responses [i].getStringParameterValue (CMQCFC.MQCACF_LAST_PUT_DATE);
int qtime = responses [i].getIntParameterValue (CMQCFC.MQIACF_Q_TIME_INDICATOR);
System.out.println (name + pdate + qtime );
}
When I execute the program, I got
Exception in thread "main" java.lang.ClassCastException: [I cannot be cast to java.lang.Integer
If I remove
int qtime = responses [i].getIntParameterValue (CMQCFC.MQIACF_Q_TIME_INDICATOR);
amd also qtime from the println, it works.
I know very little about Java. Can anyone help me on this.
Forget to mentioned that I am actually using the Jar file of MQ V7 on Windows. So the subject of this entry is not quite correct. I am just using a modified sample program and the PCF agent (I think it is part of MS0b) from MS0B. |

Have you tried:
| Code: |
| int qtime = responses [i].getIntParameterValue (CMQCFC.MQIACF_Q_TIME_INDICATOR).getIntValue(); |
or something of the kind. Looks to me like the output is an Integer and not an int.

Hi fjb_saper, thanks a lot for the pointer.
Yes, you are right CMQCFC.MQIACF_Q_TIME_INDICATOR is not an integer value. Instead it is a list (MQCFIL). I changed the code to
int[] qtime = responses [i].getIntListParameterValue (CMQCFC.MQIACF_Q_TIME_INDICATOR);
The code now seems to work except that it is returning some strange value.
QTIME on the console output shows [I@1194a4e
When I use MQ Explorer to look at the status of the queue 'Bug'
queue time is 100651116,100651116
I expect getIntListParameterValue to give me an array of integers. |

| it's likely giving you an array of Integer object, rather than int values. |

Thanks for all the help. I got it to work
qtime is an array and I used println to print qtime to the console. So it shows strange.
When I use Arrays.toString(qtime) to print. It shows the right value. |
