问题 I feel this should be easy. Just RTM and go. But I can't find the info I need. Q: Can I change the value of an @ActivationConfigProperty at deploy time without having to write any XML? More detail I have an MDB which is using the @MessageDriven annotation. Within this are a number of @ActivationConfigProperty annotations configuring it. @MessageDriven(mappedName = "jms/TestJeremyTopic ", activationConfig = { @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto

问题 I'd like to write some code to monitor the queue size on Websphere 7 MQ. This is the code I've come up with MQEnvironment.hostname = "10.21.1.19"; MQEnvironment.port = 1414; MQEnvironment.channel = "SYSTEM.CDEF.SVRCONN"; MQEnvironment.properties.put(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES); MQQueueManager qMgr = new MQQueueManager("MYQMGR"); MQQueue destQueue = qMgr.accessQueue("PUBLISH", MQC.MQOO_INQUIRE); System.out.println(destQueue.getCurrentDepth()); destQueue.close(); qMgr

问题 I've installed WebSphere MQ 7.1 on Linux platform, after which I installed WebSphere Message Broker 8.0.0.1. Now when I try to create an execution group, I get an exception: Reason code 2035. This exception states that the user is unauthorised to connect to the queue manager. I have this user added in the mqm group. I did not face any such issue when I was working with MQ 7.0.x. I searched a lot and came to know that there is user ID blocking in MQ 7.1. But, I want this user to be able to

问题 I am getting an WebSphere MQ Reason code 2195 MQRC_UNEXPECTED_ERROR when I try to connect to the message flows deployed on the execution group. Can somebody please tell me what exactly does this reason code mean? Queue manager, broker , execution group.. everything is up and running and the ports are also open. I am not getting anything worthwhile on the net. Please advise. 回答1: The 2195 return code is a high-level exception that is hit when errors are not caught at lower levels in the code.

问题 My understanding is that: MD B s (Message Driven Beans) connect via Activation Specification. MD P s (Message Driven POJO) connect via Connection Factory. This diagram from IBM is helpful: To me, this explanation from IBM does not shed much light on the difference: Connection factory -- used by the application to get connections to the messaging bus. Queue -- used by the application to send and receive messages. Activation specification -- used by the application's message-driven bean to

问题 I'm currently working on a project where I need to interface with an IBM system which communicates with the outside world through WebSphere MQ. I need to query the system in a "request-response" fashion using queues, and I will be doing this through a queue manager. However, I can't quite get my head around how this works in practical terms. Say I've got multiple instances of the same application which puts a message onto a request queue. The message gets a CorrelationId and MessageId upon

问题 I'd like to connect to a Websphere 6.0 MQ via Java. I have already working code for a "normal" queue, but now I need to access a new queue which is SSL encrypted (keystore). I have been sent a file called something.jks, which I assume is a certificate I need to store somewhere. I have been searching the net, but I can't find the right information. This is the code I use for the "normal" queue. I assume I need to set some property, but not sure which one. MQQueueConnectionFactory

问题 I am trying to migrate an application from Websphere 6.1 to 7.0 I noticed that many of the ibm MQ/JMS classes have changed/disappeared =) In particular, I am getting errors on com.ibm.msg.client.jms.JmsQueue com.ibm.mq.jmqi.JmqiObject it is saying "...cannot be resolved. It is indirectly referenced from required .class files" Does anyone know what I can do to get this to compile? thanks 回答1: Hard to say exactly from the description so I'll provide some general pointers that may be of help.

问题 I've run into a frustrating problem browsing a queue all the way through its depth. I understood that the queue needs to be opened with the MQOO_BROWSE option among the open options. Then on the first read do a GET using the Get Messsage Option MQGMO_BROWSE_FIRST. Finally, the subsequent GET's should use the MQGMO_BROWSE_NEXT option. The problem is, my attempts worked only to retrieve the first message! Upon the second GET, even with MQGMO_BROWSE_NEXT, the method threw MQRC_NO_MSG_AVAILABLE,

问题 I am using MQ Java PCF API to retrieve information from an MQ installation. There are several constructors for the class PCFMessageAgent. There is one that accepts the host, port and channel name. I have shown an extract from the documentation. public PCFMessageAgent(String host, int port, String channel) throws MQException Initialises a new PCFMessageAgent with a client connection to a queue manager. The code I have is PCFMessageAgent agent = new PCFMessageAgent(host, port, "SYSTEM.DEF
