In view of the characteristics of multi-source data fusion requirements for shipborne information systems, this thesis improves ActiveMQ and builds a shipboard robust communication prototype system. The prototype system takes advantages of reliable data asynchronous transmission to provide flexible and reliable system communication for functional platforms of shipboard information system (SIS) and overcomes the difficulties of heterogeneous system integration in SIS. This system also improves the traditional message queue model by offering multiple message queues to serve a single data link, making the native java message service (JMS) more reliable. On the other hand, the system provides a scalable clustering solution that utilizes a separate configuration center to implement the expansion, control, and monitoring of message server nodes, and dynamically distribute the load of the message server and message queue. The improved system effectively overcomes difficulties of single line and single point information source failure and becomes more interference and damage resistant.

Under the environment of the rapid development of computer network technology, the traditional Enterprise Resource Planning (ERP) has not well adapted to the development of Customer Relationship Management (CRM). In order to cope with such a predicament, the enterprises hope to establish a computer-integrated system for ERP and CRM. However, the integration of the two systems is difficult and complexity. This paper analyzed the integrated problem for ERP and CRM and gave out the solution to the integrated system based on Enterprise java Bean (EJB), java message service (JMS) and Extensible Markup Language (XML). The integration technology was provided in three aspects of functional modules, information integration and system integration. An example from an enterprise is illustrated to explain the feasibility of the integrated system.

With the growth of internet, the requirement for the communication and message exchanges between programs becomes more and more important. The message-Oriented Middleware (MOM), such as java message service (JMS), could not only greatly reduce the technical learning curve for programmers but also have some amazing characteristics: such as reliable, secured, and event-driven. In the traditional client-server architecture, not only the client side program has to maintain the resource for connections and memory management, but also the server side has to send out several copies of duplicated messages per amount of connected clients. It not only wastes the system resource but also the network bandwidth. A system this paper developed is Fast java Messaging 2 (FJM2), it's a enhancement version from Fast java Messaging (FJM). It creates a whole new JMS provider which is distributed, high performance, reliable, and easy to use and deploy. While compared with FJM, FJM2 adapts a more efficient communication protocol-Negative-acknowledgment (NACK)-Oriented Reliable Multicast (NORM), and does not adapt topic addressing. Moreover, FJM2 has the ability to work across WAN environment to extend the system coverage, and could be adapted for more different application scopes. It would benefit those who want to create a MOM system based on java and multicast protocol.

Security of messaging middleware is the key issue to ensure the integrity of news transmission. By analyzing the defects on safety of current JMS-based messaging middleware communication model, elaborating several safety problems of messaging middleware from authentication, authorization, encapsulation and audit, this paper proposes a messaging middleware security model based on data encryption and digital signature technology, it encrypt messages with symmetric and asymmetric encryption algorithm and audit some safety-related events, then the security of message transmission has improved.

Different middleware technologies have been facilitating the communication between the distributed applications. RMI and CORBA are the most commonly used technology for communication between distributed components. This research work was undertaken in view of increasing e-business requirements. The Transfer of messages in Distributed Systems (TMDS architecture) proposed in this paper is based on the concept of asynchronous communication between components. The advantage of the proposed architecture is that the sender of the message can continue processing after sending the message and need not wait for the reply from other application. TMDS Architecture ensures guaranteed delivery of the message. TMDS Architecture supports the two major domain of asynchronous messaging: (i) Publish/Subscribe and (ii) Point-To-Point domains. In addition TMDS architecture has the facility to prioritize the message, filter messages on certain conditions and the architecture also supports easy integration of new systems with the existing legacy systems.

With the demand of cooperative work between the various enterprise applications growing, communications between systems becomes the focus of attention. A prerequisite of joining an enterprise system is the ability to cope with the rigorous demands experienced within such systems. One of the most fundamental of these demands is the requirement for enterprise-level systems to have guaranteed reliable messaging between the participants of the system. The use of java message service (JMS) for enterprise applications communication and integration is increasing very quickly. This paper introduces a new JMS transport protocol, Selector Based Transport Protocol (SBTP) for enterprise applications. The new protocol uses JMS to deliver messages according to the Queue and Publish/Subscribe principle. This paper provides a brief overview of the design of SBTP, evaluates its performance, and examines the benefits of the SBTP in comparison to the other available protocols for JMS;it then concludes and highlights plans for the development of the message transport protocols.
