Hello
Can someone help me understand how to use parameters topicName and topicObject of method accessTopic in class MQQueueManager? What is possible with these parameters?
public MQTopic accessTopic(String topicName,
String topicObject,
int contact admin,
int options)
throws MQException
In MQ Explorer, I have created a topic as follows:
Topic name: my_new_topic
Topic string: my_new_string
I also created a subscription that places messages received in this topic onto a local queue.
At first I thought my_new_topic was the topicName, and my_new_string was the topicObject. But, this is incorrect.
Then I looked at the MQPubSubApiSample.java sample that comes with MQ Explorer v7, and it uses the put method of class MQQueueManager to place a message on a topic. This worked when I passed in the Topic name from the MQ Explorer Topic GUI, into the destinationName parameter. But I don't see how this approach can involve a TopicObject.
put(int type, String destinationName, MQMessage message)

Looking at your explorer view,you created a topic object with name my_new_topic. The topic string was my_new_string.
If not using a topic object you would publish directly to my_new_string...
So I really don't understand your question...
It seems there is some confusion here between topic, topic string, and topic object...

"Some confusion" is an understatement. After many hours of in depth studying and meditation atop a mountain, I came to know the nature of MQ topics 
The problem solve itself, I'm not sure how. |
