JavaLand 2015 Wrap Up After months of preparation, it all came down to three days of intense execution, and I was just one speaker. I can only marvel at the logistical acumen that was on display from the JavaLand and DOAG team. I had an action packed agenda: two conference sessions, two Early Adopter's Area (EAA) session, and one training day session. Thrown into the mix were a couple 1:1...

Java Enterprise

Now that both JSRs are in full swing I am going to offer you all a bit of a different perspective between the 2 technologies. As I have stated before I view them both complementary to each other! I want to talk a bit about the actual work of doing the JSRs themselves. As part of the JSR we deliver a reference implementation, but in reality does the work stop there? No, it surely does not.

Just like the previous blog entry "JSF 2.3 Using a CDI managed Converter" you can now do the same thing with Validators. So how does that look in code?   @FacesValidator(value = "myValidator", managed = true)  public class MyValidator implements Validator {     @Inject     MyModel model;    ..  } Note in this example...

Although a converter is considered an attached object (part of the view state) commonly people ask support for CDI injection into a converter. Since we did not want to upset the original contract of what a converter is we had to look at how we can best support the requested use case. We already had an annotation (@FacesConverter) that was being used to define a converter programmatically. To...

Validating Oracle Java Cloud Service HA One of my favorite applications from my Sun Java System Application Server days was the Cluster JSP Sample Application. In a cluster configuration fronted by a load balancer, this simple JSP provides a nice summary of which cluster node handled the request as well as the ability to test session failover. Therefore, why not try it on the Oracle Java Cloud...

Today I participated in a phone call on Adopt-a-JSR for the MVC 1.0 specification. While we do not have a whole lot of things that can be worked upon by a JUG at the moment I do want to point out that once we start publishing SNAPSHOT releases and milestones we will be looking forward to your contributions! I will tweet and blog about that day and hopefully it will be soon, but as I also...

The example describes a way to lookup a datasource that is mentioned in the @Resources annotation on the class.   @Resources(value={    @Resource(name="ShoppingCartDB", type=javax.sql.DataSource),    @Resource(name="ShoppingCartMail", type...

Imagine if, for example, the hypervisors that run EC2 were compromised - imagine almost every business you deal with online compromised, all at once. This is the never-talked-about problem with the cloud - over on my timboudreau.com blog.

Bunyan is a NodeJS library that rethinks logging in some really useful ways. I wrote a Java port you can use in your applications. In particular, with Bunyan, logs are JSON - and Bunyan comes with a great filtering and analysis tool. The Java port uses some innovative techniques to make logging simple and foolproof - in particular, a use of AutoCloseable to make a logging code simple and...
