About Oracle Java CAPS Adapter for MSMQ

This topic provides conceptual information about MSMQ and its Oracle Java CAPS Adapter.

About Microsoft Message Queuing (MSMQ)

Microsoft Message Queuing, or MSMQ, is message queuing communications “middleware” that enables applications on diverse systems to communicate with each other. MSMQ allows applications to communicate through messages, and can guarantee the delivery of messages even in the event of system or network failures.

By using messages, MSMQ can provide asynchronous communication between applications running on the same computer or on separate computers connected through a network. When an application receives a message, it processes the message by reading the message content and acting accordingly. If appropriate, the receiving application can send a response message back to the sending application. MSMQ protects these transactions by safely storing the messages in queues, which prevents message loss and make messages available to an application whenever it is prepared to receive them.

Applications using MSMQ are able to send and process messages, even when the receiving application is not available. Upon connection, the receiver can accept or pick up the messages. Applications using MSMQ’s transactional delivery mode can be assured that messages are delivered exactly one time only, and that they are delivered in the order that they were sent.

About the MSMQ Adapter

The Adapter for MSMQ allows the Oracle Java Composite Application Platform Suite (Java CAPS) to exchange data with Microsoft’s MSMQ. The MSMQ Adapter transparently integrates existing systems with MSMQ.

The MSMQ Adapter enables Java CAPS to use business logic within Collaborations or Business Processes to perform data identification, manipulation, and transformation. Messages are tailored to meet the communication requirements of specific applications or protocols.
