Exception chaining has become an increasingly popular pattern as a way to better manage exceptions. As part of JDBC 4.0, we are giving consideration to introducing exception chaining to the primary exception class definition: java.sql.SQLException.
I'm still surprised at how many people are confused about Sun's J2EE 1.4 SDK. For example, did you know it is free? Really free, even for deployment?
The jstl-spec-public project has just been launched to increase
transparency into the JavaServer Pages Standard Tag Library (JSTL)
After diving into the message-driven bean section of the EJB 2.0 specification, all is not what it seems with regard to message redelivery.
In this weblog, I look at how service-oriented architectures are an evolution of the structured programming, object-oriented programming, component-oriented architectures in terms of unit of resuability.
"hey, wouldn't it be great to have a community on java.net centered around J2EE applications, components and tools?"
A bit of Tomcat, a bit of Aspire, and a touch of master pages: and Microsoft Access comes to life. Having developed this simple minded content management system called AKC, when I look back I am given to think how well the web complements even the simplest and readily available of relational database systems. I use this site for my web logging, classified repository of articles, online documentation tool for the open sourced Aspire product, online educational tool for young children, a research aid for new technologies.
Java Web Services and XML
Ease of Development is a core driver for much of the work underway in many JSRs - particularily JDBC 4.0. At JavaOne this year we will be talking about some of early draft proposals and I will presenting our ideas, including code examples.
I am going to moderate a technical forum on Web and XML technologies. Do you have suggestions for topics and / or speakers?
What can you do if you would want to use XML but you are having performance problems? Binary encodings have been proposed and investigated for a while but they have yet to gain real adoption. Here is a proposed standard that delivers substantial performance benefits without losing the benefits of XML. Think of it as an improved GZIPed XML...
Sun has announced that it will release JWSDP 1.4 in the very near future. New features in this release include support for additional containers and support for two key news specs: BP 1.1 with Attachements Profile 1.0 from WS-I and Web Services Security from OASIS. Stay tuned to this channel for the actual release of the bits.
Our one year anniversary is almost here, which was a good excuse to do a (late) spring cleaning through the projects in the Java WS & XML community. Here is a report and a call for suggestions on future activities.
With the proliferation of java server side technologies, this tutorial from Sun is very well laid out and quite refreshing. Unlike the title this tutorial actually covers servlets, jsp, tags, web services, jaxb, soap, xslt, jsf, localization, tomcat. Essentially everything that is needed to create real world server side applications with the exceptions of EJBs. I am not complaining on that account :-). Any way good job who ever has done it.
Sun has come out with JDIC to
make moving from a web context to a rich client easier. Much as I
support the move, it doesn't help all that
much and I'm afraid that Sun is missing the point... again!
Global Education and Learning
Downloading code blindly off the net can be dangerous as seen is the bug described in this post. Always make sure to test everything you write and everything you download from the net as well.
Education & Research Community at java.net gets more help from Sun and the rest of the world. Our name is changing and we are getting a new portal!!!
Java User Groups
It is interesting how a name can sometimes summarize many ideas and discussions... Software Freedom is Simon Phipps name for a broader guarantee of freedom.
when it comes to complicated things such as setting digital watches, programming vcrs, ordering a sub for your spouse (Who always has a very discriminating taste), ordering at a local McDonalds drive through, self checkouts at Home Depot, and ofcourse software, I am a minimalist. If something is not hampering my imagination and productivity I usually don't upgrade. Well I had to learn the details and implications of the "setCharacterEncoding()" and move over to servlets 1.3 (for my compiles).
