[2003-03-27] Taming your Tomcat: Filtering tricks for Tomcat 5
Designing maintainable high-performance systems
The new Tomcat 5 server takes filters to a new level of deployment flexibility. Tomcat 5's support for the upcoming Servlet 2.4 and JSP 2.0 specifications gives filter writers a new way to integrate and deploy these flexible components -- tapping directly into the request dispatcher's operations. In this article, Sing Li takes you on a guided tour of the new enhancement and gives you some hands-on training. See how Tomcat 5 can benefit Web application frameworks and lead ultimately to the design of maintainable high-performance systems.
[2003-03-26] Bringing your Java Application to Mac OS X
Apple has just released Java 2 Standard Edition (J2SE) 1.4.1 for Mac OS X. Mac OS X has shipped with J2SE 1.3.1 installed from the beginning. Now J2SE 1.4.1 is available to all Jaguar (Mac OS X version 10.2) owners by using the software update at Apple's Java product page. Much of the time porting J2SE 1.4.1 to the Mac has been spent moving the GUI elements from the Carbon framework to the Cocoa framework. This means it is easier for your Java applications to take advantage of Mac OS X specific features when running on the platform and to look and feel more like native applications.
[2003-03-26] Java Servlet and JavaServer Pages (JSP) Technologies
MDR-EdO: Welcome to today's Java Live session on Java Servlet and JavaServer Pages (JSP) technologies. Our guests are computer scientist Marty Hall, and Sun Technical Staff Member Mark Roth. Marty is the author of the books Core Servlets & JavaServer Pages and More Servlets and JavaServer Pages. Mark is the co-lead of the JSP 2.0 specification. This chat was advertised as "new developments in servlet and JSP technologies." So let's begin with the basic question -- what's new in these areas?
[2003-03-26] The Future of Web Services Security:
Sun Microsystems' Eve Maler, chair of the Security Work Plan Working Group of WS-I (Web Services Interoperability Organization), is a leading mover and shaker in the world of Web services security. She co-founded, formerly chaired, and is currently coordinating editor of the SAML (Security Assertion Markup Language) committee, which brought together divergent XML-based security efforts in an effort to develop a common standard.
[2003-03-26] Putting Design Principles to the Test (A Java based Case Study)
It's time to consolidate on what we've been discussing in this series about design principles governing the class structure and package structure. In this article, I will present a sample case study in which we will develop a hypothetical application component and try to employ all the design principles we have learned so far, to come up with a reasonable robust design solution.
[2003-03-26] Java Tip 136: Protect Web application control flow
Web application designers and programmers often face situations where a form submission must be protected against a rupture in the normal control flow sequence. This situation typically occurs when a user clicks more than once on a submit button before the response is sent back or when a client accesses a view by returning to a previously bookmarked page.
[2003-03-26] Understanding Properties in Java and C#
This is a long and technically complex tutorial lesson. Therefore, I have broken it into six parts. You should be able to finish reading each part in one sitting.
[2003-03-21] Develop Faster With Tag Libraries
For easier and faster development, Struts provides five tag libraries that act and function just like other JSP tag libraries: HTML, Bean, Logic, Template, and Nested. This three-part article series covers the HTML tag library. Part 1 discusses how to configure a Struts application to use this library and its first group of tags, Part 2 explains the second group of tags, and Part 3 demonstrates an application that uses this library.
[2003-03-21] Turn a JTable into a Spreadsheet
The spreadsheet is part of our everyday lives. Most of us have used one to help us calculate and present data quickly and efficiently. The JTable component, which is available in the Swing package, has itself become popular among Java developers, and you might have already imagined using a JTable as a spreadsheet for your application.
[2003-03-21] Streamline Your Exception Processing
Make applications easier to maintain and support by implementing exception handling at an application level.The primary reason exceptions exist is to produce and report information about an error and the circumstances in which it occurred. (Consider my liberal use of the word "exception" to be a generic term for any type of object that extends java.lang.Throwable.)
[2003-03-21] Integrated Testing Builds In Quality
Achieve more reliable applications through methodologies, modeling, and new techniques for finding and analyzing errors. Application development tools have spent the last several years maturing and building up compliance with successive versions of Java Development Kits (JDKs);); Java standard and enterprise edition toolkits; and supporting technologies such as JavaServer Pages (JSPs), Enterprise JavaBeans (EJBs), Java API for XML (JAX), JDBC, and a host of others. Today you can use virtually any Integrated Development Environment (IDE) to build a distributed application, using virtually any of the established technologies under the umbrella of Java 2 Platform, Enterprise Edition (J2EE) or Java 2 Platform, Standard Edition (J2SE).
[2003-03-21] Sun’s new developer hang-out
In a major effort to get together an estimated 6 million Java developers across the world, Sun Microsystems is calling for developers to form the Java community.
[2003-03-21] Sun bets on wireless Java
65 million handsets all over the Java-enabled. Qualcomm’s BREW and Windows CE are lurking in the sidelines but Sun does not see them as big threats. A 100 million handsets will be Java enabled within a year, believes Sun.
[2003-03-21] McNealy: Rattling cages is good for Sun
On his Asian tour, Sun's CEO tells reporters that being controversial is good for business--then describes Intel's Itanium chip as a "serious disaster."
[2003-03-20] Sun touts Java integration specification
Promises ro reduce development costs for Java-based web services
[2003-03-19] McNealy: .Net is a joke
On a tour of Asia, the Sun Microsystems' CEO hits out at rival Microsoft, saying that viruses are a feature in .Net Microsoft and that Java is tops for developers.
