Servlet 3.1 Specification (JSR 340) is almost ready for the release. One of the new features is the support for protocol upgrade.
HTTP protocol upgrade was introduced in HTTP 1.1 (RFC 2616):
The Upgrade general-header allows the client to specify what additional communication protocols it supports and would like to use if the server finds it appropriate to switch protocols. The server MUST use...
Acteur - a framework for building scalable, asynchronous web applications using Netty + Guice with an interesting programming model
Web Forms is one of the exciting new features of the recently released BPM 188.8.131.52. To really embrace the power of Web Forms, one must understand Forms Rules, which can give your forms dynamic behavior, such as showing a field or calculating a sum total. In this example, I'm going to show you how to use Form Rules to dynamically populate a dropdown (or list).
Servlet 3.1 Specification (JSR 340) and Java Authorization Contract for Containers (JSR 115) MR3 are almost ready for release. Besides "*", the role-name "**" is introduced in the above two specifications.
In a nutshell, "*" means any role defined in web.xml and "**" means any authenticated user.
Prior to Servlet 3.1, web containers use proprietary mechanisms to add security-constraints for any...
Servlet 3.1 Specification (JSR 340) is almost ready for the release. Several new security features have been added in this version of Servlet specification.
In this blog, I will explain one of the security features, namely deny-uncovered-http-methods.
Let us take a look at a simple security-constraint in web.xml as follows:
<web-app xmlns="http://www.w3.org/2001/XMLSchema" ...
Servlet 3.1 was in Public Review in Janurary 2013. And it is in Proposed Final Draft now. Most of the new features are related to security.
In this following, I will highlight features since Servlet 3.1 Public Review:
add new API javax.servlet.http.Part#getSubmittedFileName
add new API javax.servlet.ServletContext#getVirtualServerNameThis API allows a JASPIC module to be registered in a Servlet...
Servlet 3.1 (JSR 340) is almost ready for the release. One of the new features is the support for non-blocking IO. ReadListener and WriteListener are introduced to allow non-blocking processing in Servlet.
Non-blocking IO can only be used in async (defined in Servlet 3.0) or the upgrade mode. We can set the async in a servlet with @WebServlet annotation.
In this blog, we will illustrate the use...
One of my favorite sessions at Jfokus 2013 was presented by Typesafe co-founder and Java Champion Jonas Bonér. I always enjoy discussions about how technology evolves over the decades, how we break away from concepts, then sometimes weave our way back via the latest and greatest thing, which can sometimes appear strikingly similar to something that was very much in vogue a decade or so earlier. So...
Atlassian has made some seriously great products, for example the project tracker JIRA. We recently upgraded our rather archaic version of JIRA at Magnolia to the latest and greatest offering. Everyone in the team found something in this upgrade. Some of us were desperate to use GreenHopper, others were looking forward to a better LDAP integration, and my personal favourite was the new REST API...
Sometimes, life drops a house on your code. Sometimes, it's flying monkeys. Most of the time though, the damn stuff just stops working and it's nothing so obvious as being crushed by a Kansas farmhouse or being carried away by winged primates.
For this last common case, there are a good number of great tools to help you out. JMeter may help you to reproduce the conditions under load, while...
The applications have grown together with the man dream to get more and more information, then more application have been emerging and the man had became hostage of the application.
For example we can recognized the evolution between man and machine:
In the first time: Many men to just one machine ( like mainframe's age) then one man to one machine ( in to Personal computer era) and...
And now you can go stateless!
Whenever the JSF runtime needs to perform a conversion it uses a Converter to do so. As explained in previous blog entries you have the ability to implement your own Converter. But does that mean you need to implement it for simple conversions? No, you do not, the default JSF converters come to the rescue!

Not so long ago Mark Halvorson mentioned in his presentation at the Magnolia Conference 2012 that he doesn't understand why he can't have versioning for templates in Magnolia the same way he has it for content. Then I thought why not? Should be pretty straightforward.
The first implementation was indeed easy. Similar to what Magnolia does when dealing with DMS documents - I just configured a...

So, what does it take move your existing application to the cloud? As you'd hope, not much.
In my last blog post, I explained how to add versioning capability to templates. Being able to create, view and restore different versions of templates is great, but sometimes it's not so easy to see what has actually changed. And we might not be as lucky as having comments about the change from the author, or they might be cryptic to the point of being useless.
So let's try and add the diff and...
