Java Enterprise

In the first blog entry of this series, we showed how to configure a message body reader (MBR) on an instance of Client. Specifically, our example required the registration of an MBR to convert an application/json representation of the Money bean.  Client client = ClientFactory.newClient();client.configuration().register(MoneyMBR.class); As stated in that blog entry, a Client instance can be...

Did you ever tried to visualize dependencies between pages on your average website? If so, you probably know what kind of pain it can be. The relations tend to be messy and any kind of chart displaying them is not easy to read. The other night I was looking for some charting library and run across MooWheel. Using the Wheel for rendering the deps you get reasonably readable chart for smaller site...

Somebody shown me the tool called Red Bot the other day. The tool will check the headers of responses sent by your server, the compression of the content during transfer, server clock as well as modification dates claimed by your content. The info it gives about each page of the site is broken in 3 sections - General, Content Negotiation and Caching. When I saw the tool, I thought it might...

Some Wicket goodies for my JavaOne talk. If you go to my JavaOne 2011 talk "Productively Fun Web Development with Apache Wicket and Java EE 6" you will see a demo where Bean Validation is used in conjunction with Apache Wicket. In order to accomplish that, all that you need is a single Java class that bridges the Wicket validation framework and the JSR 303 validation engine. I am...

There is a lot of well-founded buzz around HTML5 but I assert that nearly all of it stems from how HTML5 enables the UI authoring experience to focus entirely on the browser, instead of on server-side processing that delivers content to the browser. For years, I've been making the case that building a web application is really building a distributed application, and therefore the art is finding...

The movement towards digital records is generating exponential amounts of data, tremendously valuable data. But building a system to manage that data and extract value from it requires acceptance of a paradox; the system needs to be flexible and tolerant, while simultaneously enforcing structure and standards. This is hard. Many of us have felt the pain of Master Data Management (MDM). In large...

Heroku, the PaaS cloud owned by salesforce.com, announced a few days ago support for the Java language. In the process they declared Java EE to be irrelevant in the cloud world. Is that so? I try to embrace anything that helps me develop, test or deploy code faster. Cloud Computing has the potential to bring radical improvements to all these areas, hence I have been following its...

in JPA it is possible to map String-data to enumerated values. But you are limited to Strings that are legal to be used in enum-types. E.g. using '-' or plain numbers will not work. An enum using such characters will not compile: public enum ThisWillNotCompile {   VALUE,   123,   hello-world;} Thus JPA doesn't allow to map such values to enum-types (in fact it's not...

Pragmatic Programmer Stuart Holloway said in a tweet recently, “Anybody can be agile in a green field. Show me your 3rd, 4th, and 5th releases.” Well, we've been maintaining Oracle Mojarra JSF for 32 releases and, we’ve found hudson a completely invaluable tool for maintaining agility as the technology matures and requires maintenance across all the versions we've ever released...

I'm trying to get the first snapshot of JSF 2.2 published and I've just scanned through the svn logs and arrived at the following text, from which I'll derive the "Changes between 2.1 and 2.2" content. * Deprecate the CURRENT_COMPONENT and CURRENT_COMPOSITE_COMPONENT attributes   http://java.net/jira/browse/JAVASERVERFACES_SPEC_PUBLIC-784* Fix incorrect VDLDoc http://java.net/jira/browse/...

Next week I will be presenting a free webinar about Java EE 6 and Glassfish 3.1. The title can be translated to English as: "Java EE 6 and Glassfish 3.1: Simplicity + Ligthness = Productivity". The reason the title is in Portuguese is because this will be a webinar targeted at Brazilian Java EE and Glassfish users - as far as I know it will be the first webinar in Portuguese on these...

Java Web Services and XML

 Tonight I bundled the cassandra command-line interface (CLI) into virgil. Since the CLI uses the thrift-based CassandraDaemon, the main method now starts a thrift server along side the REST server.     Now, when you (or your application) issues commands through the REST interface, you can verify that they worked through the command-line interface. For more information, check...

The Early Draft for JAX-RS 2.0 (JSR 339) has recently been submitted for publication. There are number of interested features in the new draft, and I'd like to start with the new Client API. The Client API is used to access Web resources. It provides a higher-level API than HttpURLConnection, and perhaps more importantly, integration with JAX-RS providers. Let us start by defining a simple ATM...

JCP

JAX-RS 2.0: A first interim report It's been a few months already that the expert group of JSR 339 started discussion about the details of JAX-RS 2.0. The target defined by spec lead Oracle are clear: Java EE 7 shall have a RESTful API that augments current JAX-RS 1.1 API by (among others) a Client API, HATEOAS support and asynchronous invocations. So what's the status with state? As three corner...
