Learn how to create digital-certificate chains to test your software. IBM Software Engineer, Paul H. Abbott, clarifies this seldom-documented process by showing you how to use the freely available OpenSSL toolkit to create a certificate chain of any length. He also describes common certificate attributes and shows you some sample Java code for reading the certificates you create into a Java keystore.

The IBM Reflexive User Interface Builder (RIB), a new technology available from alphaWorks, is an application and toolkit for building and rendering Java AWT/Swing and Eclipse SWT GUIs. RIB specifies a flexible and easy-to-use XML markup language for describing Java GUIs and provides an engine for creating them. You can use RIB to test and evaluate basic GUI layout and functionality, or to create and render GUIs for an application.

The Jakarta Element Construction Set (ECS) is an open source project for creating markup language documents using the Java language and an object-oriented approach. Java developer Amit Tuli provides an introduction to ECS and shows you a step-by-step approach for using it to generate well-formatted status reports from log files. You will create a sample application to help you better understand ECS and its usage. You'll also learn some other potential uses for the API.

RDF is increasingly recognized as an excellent choice for representing and processing semi-structured data. In this article, Web developer Philip McCarthy shows you how to use the Jena Semantic Web Toolkit to exploit RDF data models in your Java applications.

This tutorial shows you how to build a database application using Java 2 Micro Edition (J2ME) Record Management System (RMS). It also demonstrates how to craft a MIDlet that performs the necessary logic of creating and accessing a sample database application and deploys it to a J2ME environment.

This article examines two data management strategies available on the Java platform: Java object serialization and Java Database Connectivity (JDBC). While neither data management strategy is inherently superior or inferior to the other, when it comes to managing enterprise information systems, JDBC wins hands down.

A discussion of MIDlet development on the Nokia 6600 making use of the MIDP 2.0 and MMAPI. The artcile will attempt to guides you through many of the quirks of this phone, not least of which is the 'Mickey Mouse' effect of the audio capture tool.

Privacy monitoring technology in information technology systems is now necessary in order to ensure compliance with stated privacy policies, especially in the customer information management systems in enterprises such as Customer Relationship Management (CRM). Privacy policies allow organizations to control the use of personally identifiable information (PII) according to individual choices. The IBM Tivoli Privacy Manager (TPM) provides server support for creating, deploying, and administering privacy policies as well as for checking conformance to policies and for logging auditable data on data accesses. However, applications using TPM must use an agent that is able to intercept each access of PII and interact with a TPM server for auditing and enforcement. This is the function of a privacy monitor.

The Reference Monitor's purpose is to simplify the task of developing new privacy monitors, which are integration points between an application and the Privacy Manager server. IBM Tivoli Privacy Manager provides a way for businesses to meet various privacy regulations. It incorporates a privacy management middleware system that applies privacy rules to existing applications while minimizing the impact to the environment.

This is a simple function used to encode text and attribute values before adding them to your XML documents. This code can always be extended to handle maore special characters

Follow along as Java architect Abhijit Belapurkar leads this detailed, behind-the-scenes introduction to two distinctly different (yet related) models of authorization: the code-centric model of the Java 2 platform security architecture and the user-centric model of the Java Authentication and Authorization Service.

In server-side control architectures a majority of the control events must be handled on the server side to update the state of the control. For every user event, the entire page data is sent back to the server as part of the form submission, even data that has not changed or is not affected by the user event. This article shows you how to use containers to overcome data-processing redundancy, which can otherwise drain the life out of your handheld or Web server.

SA4J is a technology that analyzes structural dependencies of Java applications in order to measure their stability. It detects structural "anti-patterns" (suspicious design elements) and provides dependency web browsing for detailed exploration of anti-patterns in the dependency web. SA4J also enables "what if" analysis in order to assess the impact of change on the functionality of the application; and it offers guidelines for package re-factoring.

Most Java programmers use some kind of tracing system to keep track of potential errors and problems in code under development. However, multithreaded and multiplatform systems can generate a large and baffling amount of tracing data. This article offers tips that will help you make sense of trace data from complex applications.

Code example to demonstrate how to access Google on your WAP phone using JSP pages.

This article explains all the Java code required to send emails using Java applets, thus hiding/protecting your real email addresses.

In an enterprise environment, you can easily end up in a tangle of modules with a number of third-party libraries and frameworks. While a number of tools are available to aid you in comprehending complex programs, most are expensive and time-consuming to learn. Aspect-oriented programming can be applied to a wide range of programming scenarios, including the comprehension and maintenance of legacy applications.

Most forms today store the user input into a database, but while there are many examples of building form pages or form action pages that echo or mail the input, I couldn't find a lot of examples of form action pages that store input into a database. This flash movie is for beginning JSP developer and attempts to explain the basic concepts involved in capturing and storing user input, a process that will be used in nearly every page you develop.

Get your applet out of the sandbox. This guide takes you through the steps involved in creating digitally signed applets. These trusted applets can overcome the restrictions placed by the sandbox such accessing local files and folders.

This code source displays count of records in MySQL. We are using a SQL statement. You can easily modify the code to use in different languages. But this code can be used for JSP with MySQL. We will use Connector/J driver to connect database.
