Web services have opened opportunities to integrate the applications at an enterprise level irrespective of the technology they have been implemented in. IBM's CICS transaction server for z/OS v3.1 can support web services. It can help expose existing applications as web services or develop new functionality to invoke web services. One of the commonly used protocols for CICS web services is SOAP for CICS. It enables the communication of applications through XML. It supports as a service provider and service consumer independent of platform and language. SOAP for CICS enables CICS applications to be integrated with the enterprise via web services as part of lowering the cost of integration and retaining the value of the legacy application. SOAP for CICS also comes along with the implementation encoder and decoder. This article describes two cases where CICS acts as ... (more)

Performance Improvement in a J2EE Application

Java is hot. Just nine years old, it has become one of the leading development environments in the world. Millions of programmers and thousands of companies use it, and half of all IT managers expect to deploy J2EE applications this year. But Java's popularity hasn't necessarily made it easy for the growing population of Java code jockeys. Ever-shortening production cycles have kept the heat on programmers, who increasingly work in large teams to meet production milestones. And every day those teams come face-to-face with an immutable law of software development: the more code y... (more)

Reference Architecture for Securing Web Services in a Heterogeneous Environment

Web Services have played a key role in integrating heterogeneous applications, particularly in cross domains. As part of identity management, Security Token Services are used for request and response tokens. However, we need multiple communication channels among Security Token Services when multiple applications in different domains try to reach other Web Services. In this article we have proposed a Master Security Token Service (MSTS) that can act as a broker for all security authorization without duplicating the effort at every domain. In a world of heterogeneous systems where ... (more)

Innovative Implementation of Cloud-Based SaaS Enterprise Frameworks

Traditionally business process services are built on applications that are running within the enterprise to fulfill business demands. In the recent past, the concept of SaaS Clouds gained significance with services being hosted in a common cloud environment within the enterprise or outside the enterprise. In this article, we propose an innovative implementation of Cloud-based SaaS Enterprise Frameworks in "Corporate Action Events" Processing. A lot of discussions have appeared on how enterprise architecture services and cloud-based services, namely SaaS, are connected within an ... (more)

Cloud-Based Reference Architecture

During the past few years enterprise services have been leveraging cloud-based technologies for several reasons including scalability and automated provisioning capabilities [1, 2]. In a development / design environment, cloud platforms provide dynamic and repeatable processes for creating environments that help reduce lead times and provide cost-effective optimizing infrastructure apart from eliminating manual intervention and minimizing rework due to environment defects. In a deployment environment, the cloud leverages virtualization, distributed applications and grid-based a... (more)
