Service-context propagation over RMI: Implementation follow-up
This follow-up article addresses implementation concerns of Wenbo Zhu's JavaWorld article " Service-Context Propagation over RMI," (January 2005). In this article, Zhu describes a concrete framework implementation and elaborates on some important technical aspects. While his previous article mainly discusses concepts, this article focuses on design and implementation. Related source code has been posted on SourceForge.net and named "extrmi" (extended Remote Method Invocation). Interested readers can use the published open source implementation as a simple framework library in related system design. New features, such as common purpose interceptor libraries, will be released in the future.

Create an application-wide user session for J2EE
Despite its comprehensive sets of APIs for writing distributed applications, J2EE does not provide an application-wide session. While Web applications can use the HttpSession facility, this context won't automatically carry over to Enterprise JavaBeans or J2EE clients. By combining code generation with a mixture of aspect-oriented programming and a hint of design patterns, it is possible to provide such a context across components in an enterprise application and hide most of the complexity from the developer. This article shows you how.

Reflective XML-RPC
Java reflection offers a simple but effective way of hiding some of the complexity of remote procedure calls with XML-RPC (XML-based Remote Procedure Call). In this article, Stephan Maier shows how to wrap XML-RPC calls to a remote interface using the gadgets from the Reflection kit: The Proxy, the Array, and BeanInfo classes. The article will also discuss various ramifications of the approach and the use of reflective methods in RMI (Remote Method Invocation).

Service-context propagation over RMI
CORBA supports the passing of service-context information implicitly with requests and replies over remote object interface invocation. Without instrumenting the underlying protocol, Java RMI (Remote Method Invocation) can't easily support transparent service-context propagation. This article describes a simple and efficient design approach for supporting such capability over RMI. In building RMI-based distributed applications, such an approach can serve as a basic building block for implementing infrastructure-level functions, such as transaction, security, and replication.

Call on extensible RMI
Remote Method Invocation (RMI) has become a standard communication mechanism between remote Java objects. In spite of that popularity, the lack of a robust security framework has hindered RMI's acceptance for wide-area distributed computing. The latest RMI framework, Jini Extensible Remote Invocation (JERI), introduced as part of the Jini 2.0 release, features a powerful, highly configurable RMI security mechanism. This article presents an extensible RMI overview and demonstrates JERI's configuration features.

Empower RMI with TRMI
The Java RMI (Remote Method Invocation) API provides us with a clean way to build distributed Java applications. The components that make up these applications communicate with each other by invoking methods on their remote counterparts. Transparent RMI (TRMI) extends the RMI API to simplify distributed application development by eliminating most of the standard API's overhead.

Jini-like discovery for RMI
Not yet on the Jini bandwagon? Despite its powerful mechanisms, Jini has yet to be accepted in mainstream Java development. Until that happens, developers need to find better Remote Method Invocation (RMI) solutions. This article walks you through a Jini-like discovery mechanism for your RMI development.

RMI books hit the shelves
At last! New books dedicated to Java's Remote Method Invocation technology have arrived in bookstores. In this article, Gregg Sporar reviews and compares two new Java RMI books so you can choose the best one for your programming needs.

Accelerate your RMI programming
Beginning with JDK 1.1, serialization and Remote Method Invocation (RMI) were added to the Java platform. While serialization and RMI are easier to use than alternate technologies, RMI usually runs slower than equivalent CORBA or remote procedure call (RPC) solutions. Fortunately, RMI was designed so that you could apply hand optimizations to gain more speed. This article shows several of those optimizations, including one that reduces serialization overhead with Java's externalization mechanism. (4,000 words)

Savor success with Java on the front end
Java architects and managers face the challenge of choosing among Swing-based, HTML-based, and XML-based front ends for their applications. In this article, Alex Kalinovsky shares his experiences with these three technologies, and provides criteria and tips for choosing among them in your Java development. Finally, you'll learn an innovative approach that bridges Java Swing and HTML with minimal effort. (3,900 words)

Manage distributed sessions
Using RMI and the Proxy API introduced in JDK 1.3, this article describes a technique that allows one or more servlet servers to maintain session information on one or more session servers. By adopting this architecture, no single point of failure will exist for session management. (2,700 words)

The magic of Merlin
This technical overview will give you insight into the various new features and APIs of the upcoming JDK 1.4 -- code-named Merlin. The beta version is expected to be released this month. (3,000 words)

Browse user interfaces for Jini services
The ServiceUI specification developed by the Jini.org community defines a suggested procedure for attaching user interfaces to Jini services. In this article, Jeffrey Peden -- a new contributor to the Jiniology column -- introduces you to a simple ServiceUI-based example service. Then he shows you how to build an application for browsing and launching user interfaces for Jini services.

Java Tip 108: Apply RMI autogeneration
Using the tool in this tip, you can make objects written with local semantics remote. The tool creates remote interfaces that have roughly the same method signatures as the local interfaces. These generated interfaces form a layer between the application server interfaces and the RMI runtime. Client-side translation from the generated interfaces to the application server interfaces is performed via runtime-generated proxy objects. You may also use the tool to "RMI-retrofit" existing interfaces, even those for which no source code is available. (1,500 words)
