Last week's kickoff of FESI's research program went very well. There are a number of folks (>500) who are now following this blog on Java.net, and a number who have gotten involved. While we wait for more folks, we'll be researching new technologies, the first being NOSQL databases.
If the kind of topics we're research interests you, please feel free to join the project;...

Meeting with OSGi Experts
Although I had interacted with a number of active members of OSGi  expert group, last week I had the opportunity to meet some of these experts at an OSGi Enterprise Expert Group face2face event held at LinkedIn's Mountain View office.

There are times when things hurt so much that you feel urged to blog about them once solved. This is one of them.
Our company is using XSL heavily for reporting (generating vector charts in PDFs on the fly from data analyzed by GlassFish), so it is not very amazing that we found some bugs in the XSL transformer (a.k.a "JAXP Implementation") contained in GlassFish. As we're not so fast...

What I realized shortly after we put out Magnolia 4.3 is that while we tried to explain new multisite support for example in this screencast there are still plenty of grey areas and lot of confusion when people actually get to use the multisite support. And I think I wrote and talked about this topic earlier as well.
Of course as with any new functionality, there are still...

This is the first edition of a new column I'll be writing each weekend titled "java.net: the Week in Review." In the column, I'll present all of the previous week's Java Today news items, a selection of java.net blog posts, polls, and spotlights.
I'll organize the presentation by categorizing the featured news items, so if, for example, your interest is JavaEE and GlassFish, you'll be...

Once again the FUD around Solaris and OpenSolaris fate started to spread after Dana Blankenhorn misunderstood the licensing terms and used a eye catching and visitor increasing title, Oracle taking back OpenSolaris, for his blog entry. Well, from this article we can get that even the veteran writers can get things wrong and spread incorrect news :-)
Folks, Solairs is one of the biggest Sun assets...

My last blog
entry about JSR-314-OPEN@JCP.ORG was over a year ago. This list is the official Expert Group (EG) mailing list on which the development of the JSR-314 specification (JSF 2.0) is discussed. The
information on how to subscribe/unsubscribe to this list changed in June
2010, but I haven't updated any existing information or blogged any new
information about it. This is the overdue...

I wanted to describe an interesting problem I recently faced that involved the most excellent JAX-RS specification and its Jersey implementation. The quick overview is that we wanted the output of our JAX-RS resource classes to be client-agnostic, but we also wanted the ability to insert a decorator of sorts in between the objects we were returning and the normal JAX-RS serialization/...

Administrators are always looking for a more effective, easier to use, and less time consuming tool to use as the interface sitting between them and what they supposed to administrate and manage. GlassFish provide effective, easy to access and easy to simple to navigate in administration channels which cover all...

As promised earlier, I am going to quickly go over the key points I gathered from the talks I attended at eclipsecon and I also want to brief you about my topic at the conference. Because of a migrane attack earlier today which I firmly believe was caused by severe jat lag, I could not attend as much on day #2 as I had earlier decided to, and that's the very reason why I will keep...

Spring framework is one of the biggest and the most comprehensive frameworks Java Community can utilize to cover most of the end to end requirement of a software system when it come to implementation.

There are several ways to enable user authentication for web based applications, like .htaccess files, plain tekst files, databases, LDAP, etc. They all have their pros and cons. In case a central, flexible solution is needed, either a database or LDAP solution can be used.
I chose for an LDAP solution since it can be reused by many web and application servers and the applications that run on...

I wrote about Magnolia cache few times already since it have been re-implemented for Magnolia 3.6. And it seems like with Sprint 4 of Magnolia 4.3 it came back to bite me.
There was a bunch of tickets related to various aspects of the cache. Most of it was related to the fact that the default cache key (only URI) was not enough for many installations which were...
