My MDB (Message Driven Bean) on message-inflow-driven-bean for IBM MQ using MQ resource adapter on JBoss. reference link http://www.ibm.com/developerworks/websphere/library/techarticles/0710_rit... MDB is working fine, but its allowing by default multiple instances of MDB (concurrent MDBs). As per my project requirement, suppose to use only one instance of MDB. Plz suggest me how and where i can configure the attributes related to MDB concurrency? or a example with concurrency settings would be great!
