This month the whole JDJ crew, minus Mr. Briggs, was at the Hilton in central Manhattan for our JDJEdge conference. It was a great show with much discussion regarding the state of our industry and where it's heading. As usual the old 'Web services' debate was high on everyone's agenda,...
A big date in the European gamer's calendar is the European Con- sumer Trade Show (ECTS) in London. It's a time for 16-year old boys to polish up their fake IDs, dust off the letters confirming their internship at a large game publisher (printed earlier in the week on letterhead paper ...
Before we get started, it's worthwhile noting that I'm not a big fan of WAP. Well, not the protocol itself exactly, but WML-based Web sites - the whole idea of browsing the Web on your mobile seems somewhat flawed when your screen real estate is minimal and you probably have only one m...
Many development shops have used J2EE to build a successful business-logic tier but have fallen short on obtaining the desired look and feel. On my current project we considered using applets as substitutes for GIF-based buttons, creating a utility to modify tree-based structure data a...
(Troy, MI) - Idetix Software Systems Inc. announces the availability of the Revize v3.5 Content Management and Delivery System (CMDS). A platform and Web server-indepen- dent content management software built in pure Java, Revize enables nontechnical content editors to manage and ch...
We have many stories of skilled engineers who've done a great job on contract and full-time positions, leaving behind happy managers who sing the engineer's praises for the rest of their days. We've also seen engineers self-destruct at each step of the hiring process, eliminat...
Our world has been changed. We have been changed. Emblazoned in our collective consciousness are indelible, fresh images of unspeakable carnage. We will carry these images with us - shaped in psychic scar tissue - for the rest of our lives. For some of us, September 11 will ma...
Lightweight Directory Access Protocol (LDAP) is fast becoming a de facto access method for common directory information. XML is now the standard for data exchange on the Web. The relational database, a technology for modeling data in table form, has always been the most popular way to...
As time goes by, J2ME is the buzzword that's appearing in more and more magazines and talked about beside more office coffee machines than any other. And slowly, the big handset manufacturers are releasing their first MIDP-compliant phones into the marketplace. In previous iss...
Sun Microsystems have just announced the Java Blueprints for Wireless. The Blueprints for J2EE have been available on the Java site for some time now, and the Wireless version in beta form for a month or so -- however with this announcement they have also 'tidied up' the site somewha...
I'm developing an Internet application where the user can register. How would i check if the e-mail address entered is valid? I have a couple of ideas you can implement. First, I suggest using JavaScript in the browser to check for allowable characters by scanning the input. Th...
Stop the presses! Clear the rain forests! The Merlin books are coming! The Merlin books are coming! This thing is huge and the books will keep getting bigger. Forget about thin clients. The runtime class libraries alone have jumped from 13.5MB in the 1.3 release to 22MB with the new ve...
Did you use EJBs in your last J2EE project? Many Java programmers (and their managers and CIOs) would consider this a strange question. 'How can it be a J2EE project if it doesn't include EJBs?' they might ask. The answer is: Sun currently lists 11 J2EE component technologies of which ...
Up and Running I purchased a Handspring Platinum last week, and one of my first goals was to start writing Java apps on it ASAP. After many failures, I dug through my copies of JDJ and found the issue with Jason Brigg's article on J2ME and application compiling ['Hello...
New York, NY, September 23, 2001 - In spite of what many thought might prove insurmountable obstacles, the international software industry has provided New York City today with a resounding indication that heavy hearts and thoughts are not to be permitted to become a barrier to returni...
First things first: I'd like to take a moment to reflect upon SYS-CON's JDJEdge Conference in light of the tragedy that shocked America on September 11. The best way to deal with a terrorist act is to not give in and allow it to disrupt everyday activities. To that effect, JDJEdge took...
Most developers build J2EE applications using their own security mechanism. This causes problems when other applications are introduced, because more logons have to be remembered and users have to physically log on multiple times to use different Web applications. A single sign-on allo...
As an industry we used to consider mobile/wireless computing to be the next frontier. Now it has become part and parcel of critical, enterprise applications ranging from Customer Resource Management to Enterprise Resource Planning. Many of the early mobile computing efforts that I've r...
In the beginning there were servlets, and it was good. They were much better than the alternatives, and allowed for scalable, robust Web development. But there was trouble in paradise. Web development partitioned itself into two camps: art school dropouts (invariably Macintos...
It's often said that 'a picture is worth a thousand words' - and I've generally found this to be true. In fact, it's often easier for users to digest numeric data when it's displayed in picture form, such as with a chart or graph. Business analysts have long understood this concept and...
There are many facets to J2EE Web application development. It's a powerful platform that offers a variety of possibilities and capabilities, with many different approaches and models of development available. This is both a strength and, for newcomers to the platform, an Achilles' heel...
(November 26, 2001) - With the Merant spinoff, Datadirect Technologies, now completed in the early half of this month, it will be an interesting company to chart the progress of. Datadirect produce the well known JDBC drivers for a number of well known databases, but what is inter...
