Hi,

Is there some where a good example how to create Broker Response Message?


We have a jms client writing data to the SYSTEM.BROKER.DEFAULT.STREAM queue and version 5.x WMQI Broker reads and redeliveres the message to the other systems. There is no MQ Publish/Subscribe broker running. Operating system is AIX 5.3.

JMS client fetch an "error com.ibm.mq.jms.NoBrokerResponseException: MQJMS5053: ..."

I have tried to create Broker Response Message but JMS client don't like it:

MQJMS1086: Error reading RFH
at com.ibm.mq.jms.services.ConfigEnvironment.newException(ConfigEnvironment.java:418)
at com.ibm.mq.jms.RFH.<init>(RFH.java:156)
at com.ibm.mq.jms.SubscriptionHelper.checkResponse(SubscriptionHelper.java:1065)

at com.ibm.mq.jms.MQTopicPublisher.publish(MQTopicPublisher.java:386)
at ois.cir.server.CIRJMSConnectionManager.sendMessageToTopic(CIRJMSConnectionManager.java:243)

and

The linked exception is:

...

This is probably a dumb question, but why don't you just use your WMQ broker to send back a response message?

Also, the Publish/Subscribe User's Guide should fully detail all the broker messages.

Thanks for guiding me to look from P/S User's Guide.
After several attempts we managed to create a valid Broker Response Message.

It was quite a confused written in P/S Guide:

In section "Response messages" it says
"Each command message that the broker processes can generate a response message. A response message has a similar format to a command message; the NameValueString in the MQRFH header contains the response to the command"

.
.
.

Standard parameters: CompCode, Reason, ReasonText
Optional parameters: DeleteOptions, ErrorId, ErrorPos, ParameterId, PublicationOptions, QMgrName, QName, RegistrationOptions, StreamName, Topic, UserId

.
.
.

Optional parameters Command

name: "MQPSCommand" (string constant: MQPS_COMMAND)
value: The incorrect command that was specified when a command fails with MQRC_RFH_COMMAND_ERROR. DeleteOptions

name: "MQPSDelOpts" (string constant: MQPS_DELETE_OPTIONS)
value: The incorrect delete options that were specified when a command fails with MQRCCF_DEL_OPTIONS_ERROR.

.
.
.

But in section "Publish/Subscribe name/value strings" in page 59 it says
"
The first occurrence of an ‘MQPS’ tag-name must be MQPSCommand, followed by a
tag-value which identifies the command to be carried out. Subsequent ‘MQPS’
tag-names and their values identify any options for that command (if they occur
before the MQPSCommand tag-name, the command will fail)."

A valid Repsonse looks like this:
