JAAS provides pluggable authentication, which means ActiveMQ would use the same authentication API regardless of the Techni Que used to verify user credentials (a text file, a relational database, LDAP, and so on). All that's required is an implementationof the Javax.security.auth.spi.LoginModule interface and a configuration change to ActiveMQ. Fortunately,

JMS is a technical specification for providing a messaging service that develops all the data structures and interaction processes throughout the messaging service delivery process. ACTIVEMQ, the Message Queuing service, is the ultimate implementation of message-oriented middleware (MOM) and is a true service provider.One of the standards of JMS is, or is, a protocol. Messaging is typically used for enterprise-level applications. There are mainly topi

JMS (Professional technical specifications on the Java platform)
The JMS-the Java Message Service-application interface is a Java platform-oriented messaging middleware (MOM) API for sending messages and communicating asynchronously between two applications, or distributed systems. The Java Messaging Service is a platform-independent API, with most MOM providers supporting JMS.
JMS consists of the followin

Introduction to MQ:
MQ is all called the message queue, and Message Queuing (MQ) is an application-to-application communication method. Applications communicate by writing and retrieving data (messages) for applications that enter and leave the queue, without requiring a private connection to link them. Message passing refers to the process of communicating between programs by sending data in a message, rather than by directly invoking each other, and directly invoking techniques such as remote
