BW-JMS-100015/100039 Activation error with process starter [TEST.process]
caused by: Could not create queue message receiver.[Destination=Queue[qsample1], Selector=null]
caused by: javax.jms.InvalidDestinationException: Not allowed to create destination


Ans) It can be just an error on username and password or the user does not have permissions to create queues/topics.

Below are the steps to give permissions to the user to create destinations dynamically in TIBCO Designer during run time:
1.Start TIBCO EMS Server.
2.Login to TIBCO EMS Administrator Tool using admin user.
3.Once connected then run below command to check available Queues/topics.
show queues/topics

4.You can see that there is no queue/topic available with the name '>'
5.Create one topic with below command.
create queue >
create topic >

6.Now Try to connect your dynamic topic using your code you should be able to connect to EMS Environment and can create dynamic topic.

Ans)
If you are using Tibco JMS for the first time, you need to create GenericConnectionFactory , QueueConnectionFactory and TopicConnectionFactory in EMS Administrative Tool. Make sure you add special character ">" in your ems queues.conf and topic.conf files.


Command to create Generic:


create factory GenericConnectionFactory generic URL=tcp://7222


Command to create Queue:


create factory QueueConnectionFactory queue URL=tcp://7222


Command to create Topic:


create factory TopicConnectionFactory topic URL=tcp://7222
