The 2007/2008 Sun Tech Days season kicked off today in Boston, MA and even though the event is much smaller in scale than JavaOne, it still had the same atmosphere: People wandering around from booth to booth with giant backpacks and huge id badges trying to figure out where to go next! I suspect tomorrow will be busier than today since that is when most of the technical sessions and all of the...

A new Sun Developer Network article, Handling Chunked Requests in Sun Java System Web Server 7.0, addresses the topic of breaking message bodies into chunks of arbitrary lengths with transfer coding from the HTTP/1.1 protocol. Included are descriptions of how Sun Java System Web Server processes chunked requests and how you can handle those requests in Netscape API (NSAPI) plug-ins.

As I've blogged before, we've been playing with mercurial a bit lately. So today I'm happy to announce that the read-only GlassFish v3 source code repository is available at http://hg.glassfish.dyndns.org/. You can check out the repository by running:
hg clone http://hg.glassfish.dyndns.org/ glassfish_v3
We'd like to shuffle files around to follow the proper maven convention, but in the mean...

In the last few weeks I was asked to help to integrate a set of built-in-house web applications with a Single Sign On (SSO) solution. After working with people from different teams, I realized that it would be a good idea to write a brief description of how the SSO solutions work in general. Perhaps this might help you to get started if you have to do something like this at some point.
SSO is by...

I enjoyed reading Seven Habits of Effective Developers, ZDNet Asia's interview with Sun staff engineer Lee Chuk Munn, who likens writing applications to writing books. The habits he cited include: understand the problem, use appropriate tools, strive for simplicity, and so forth.
Hard to argue with any of them, I think, in particular the points on simplicity and clarity. Those are goals for me...

When you try teach anything new for someone, IMHO the easiest way is to do that relating with something you already know. So far Struts is a framework that almost everybody touched at least once. So I will use some of Strtus concepts to explain jBPM process execution.
jBPM is not just a Process Machine, locked in just one way to promote interaction between tasks, in fact jBPM is...

In the second part of the series, you can see how we can utilize EJBCA to create certification for a client side application which will communicate with Glassfish server when Client cert authentication (Mutual Authentication) is enabled whether by changing the listener attributes or by describing it in the web-config.xml.
In order to create client certification we will need to perform...

OK, native queries in JPA. Not really well documented. Of course I understand that we really should not be doing that, but hey there are times where it is just plain easier.
The following code snippet goes after an Oracle sequence and gets the value.
EntityManager em = this.getEntityManager();Query query = em.createNativeQuery("SELECT BLOG_ITEM_SEQ.nextval FROM DUAL");Vector blogItemRow...

The motivation behind re-namespacing Dojo for jMaki was simple. We want to have both Dojo 0.4.3 and Dojo .9 running in the same web application and we also want to give our users the ability to use jMaki many years in the future. So I undertook the task of re-namespacing Dojo by hand and quickly found out that it was a involved task. Reason being there are 27350 instances of the word Dojo spread...

Because I was presenting MCP at
the first ever Jazoon conference, my
friend and expert JSF Developer Alexander Jesse invited me to speak at
the first ever JSF User Group meeting. The meeting was held at a Credit
Suisse office in Zürich on the evening of the last day of the
Credit Suisse is the largest financial institution to go public with
its investment in JSF, though...

During the latest days I've been fighting with my hosting provider because I tried to deploy Xwiki (xwiki.org) 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

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....
