During the latest days I've been fighting with my hosting provider because I tried to deploy Xwiki ( in my hosted web site. The core issue was XWiki requires that the web container security policy includes: permission java.lang.reflect.ReflectPermission "suppressAccessChecks"; Actually, it's Struts and Velocity that requires that, not XWiki code itself. See for more info http://...

In Widgets talking to Widgets Carla describes how widgets from different toolkits can easily communicate. There is a more basic level of communication which you can do declaratively which we call jMaki Actions jMaki Actions are a declarative way of associating widget behavior. Consider a case where you have a Dojo Fisheye and you simply want it to select a tab or URL when an item is clicked....

The Portal Post, Sun's group blog on portal development-related topics, recently underwent a redesign and now boasts a cool logo, pointers to a wealth of references, and frequent postings—at least one a day. The topics range from development tips to the latest in the open-source portal projects. Really impressive! Kudos to the heroes behind the scenes—the Sun Java System Portal Server...

Back in college I spent many hours of my copious Freshman year free time playing LHX on Will Day's PC. At the time, all I had was an Apple //c, which was already behind the times by then. As you can read in the Wikipedia entry, this was a flight simulation game. The thing I remember most was the "missle-cam" view, where you could fire a TOW missle and then switch to the missle's eye view,...

Den här veckan är jag i Stockholm och integrerar Grizzly ihop med Sailfin hos Ericsson. En bra grej är att jag lär mig mera SIP på samma gång, samtidigt som jag hittar flera likheter med mitt Comet arbete :-) Kanske kan få sno lite för en Grizzly Commet variant!!! Talking about Comet, if you are looking for a job, there was a post on the Grizzly mailing list about a position in...

I've been spending significant part of my time this week on HK2. After some initial work on configuring components inside HK2 and talking to Kedar who knows the current GF configuration mechanism inside out, I decided to make some serious changes to the way HK2 works internally. In the initial work, I used to load configuration directly into components. While this was faster, it prevents us...

I spent a good portion of the day on HK2 (the rest went to the usual "fix bugs now! I mean NOW!" drill that we all know right before a big release.) Much of the productivity improvements in HK2 (compared to how GFv2 is done) come from the fact that HK2 comes with a Maven plugin that knows how to build a HK2 module. It's much like how Maven plugin is built by Maven, where all kinds of additional...

Our team just released four JBI Components, a SIP BC, an XMPP BC, an RSS BC, and a UDDI BC . Having developed those components, we're now reaping the rewards; we're able to combine these low-level collaboration "services" to produce new and cool collaboration capabilities. Essentially, the four components together create a collaboration platform. One use for just such a platform might be a...

This Sample Store Catalog app demonstrates the usage of JavaServer Faces, a Catalog Stateful Session Bean, the Java Persistence APIs, and Seam to implement pagination of data sets. I took this example  Pagination of Data Sets in a Sample Application using JSF, Catalog Facade Stateless Session, and Java Persistence APIs  and refactored it to use Seam on Glassfish by following the steps...

Glassfish v3 is built by Maven 2, so most of the time the edit/build/debug cycle is as easy as: $ mvn -o compile$ mvn gf:run Now, when I am debugging a problem, I often want to see more detailed logs that are recorded at INFO/CONFIG/FINE/etc levels. Unfortunately, the java.util.logging package doesn't make this very easy — you'd have to write a property file, and use a system property to...

I agree with Shaun Connolly's observation that "While they [JBI and SCI] may share some similar patterns, those who pit SCA vs. JBI only demonstrate their inability to distinguish between the two perspectives". In fact, we set out to prove the assertion that: - JBI and SCA are entirely complementary. And we've made quite a bit of progress by taking an example SCA composite application /...

A few months ago I created the revolver as a weekend project to provide an alternative way of providing top level navigation on your web size. I thought I would share this with everyone as a jMaki widget. .arrowRight { background: url( top right;width:40px; height:30px;background-repeat: no-repeat;cursor:pointer;position : absolute } ....

Before you "host" your module on a server for others to download, it would be wise to test it out yourself. This blog describes how you can test your update center module locally on your GlassFish container through the updatetool client. Hopefully you already know how to create and package your update center module. Here's what you do to "host" the module on your local running instance of...
