MVC 1.0 Generator

The JPA Modeler plugin for NetBeans provides visual support for creating, designing and editing entity relationship models. It also provides Java code generation and new for version 1.5.5 is that it provides support for generating MVC 1.0 applications.

Check out MVC 1.0 Generator Tutorial to see how it works.


Kudos to Gaurav Gupta (@jGauravGupta) for this awesome tool! Another proof that NetBeans is the IDE for developing Java EE applications!

NetBeans Dream Team

It is great to start 2016 with the announcement that I have been included in the NetBeans Dream Team!

I always try to be as objective and unbiased as possible when writing and talking about tools and technologies, but I guess it has been pretty obvious that NetBeans is my favorite IDE and in my opinion the best IDE for Java EE development. Being a member of the Dream Team will enable me to contribute even more to make this great tool even greater.

More information about the NetBeans Dream Team can be found on the wiki.

Snoop becomes SnoopEE [ˈsnuːpı]

SnoopEE [ˈsnuːpı] The lean and simple discovery mechanism for Java EE based microservices.

What’s in a name, really?

Naming is hard! When I came up with the name Snoop for my discovery mechanism for microservices based on Java EE, my though was to associate the name with snooping around for services to discover”. It seems, however, that most people’s thought goes to Snoop Dogg when hearing the name and that was never my intention.

That is one of the reasons for the renaming. Another consideration is that I want to point out that the best fit for SnoopEE is for Java EE!

At the same time I don’t want to signal that it is only for Java EE. I want it to be just as lean and simple no matter what technology used to implement the services. That is the only reason why I have been a little reluctant to the renaming.

SnoopEE has a nicer feel and as the twitter poll indicates, I am not alone thinking this.

For the record, I have nothing at all against Snoop Dogg! I just feel that Snoopy the dog is a little bit cuter…

I have crated a new page for SnoopEE, but as for everyhing else, such as GitHub repo, maven coordinates and naming, it all stays as it is until properly announced otherwise.

Cool Security Feature in MVC 1.0

If you are developing web applications, sooner or later you will come across something called Cross Site Request Forgery. The most common way to prevent CSRF attacks is by embedding additional, difficult-to-guess data fields, or tokens, in requests containing sensitive data.

Support for CSRF protection has been added to the MVC 1.0 specification. It goes like this:

First, enable CSRF Protection in your application configuration by setting the to either CsrfOptions.EXPLICIT or CsrfOptions.IMPLICIT.

Then add the CSRF token to your forms. The Csrf object is available in Expression Language as mvc.csrf .

If  CsrfOptions.IMPLICIT is used, you’re done. All controller methods annotated with  @POST and that consumes the media type x-www-form-urlencoded will be automatically checked for a valid CSRF token.

If  CsrfOptions.EXPLICIT is used, then the   @CsrfValid annotation must be added exlicitly to the methods you want the CSRF token to be validated.

And that’s all you need!

Meet Snoop @ JavaOne

JavaOne in San Francisco is less than a month away. If you have not registered yet, do so now!


So far so good! Then you will need to add sessions you want to attend to to your personal schedule. Make sure you don’t wait until the last moment. The most popular sessions tend to fill up pretty fast.

My presentation Meet Snoop – a Discovery Service for Java EE may be can be found in the Schedule Builder by searching for CON1615. Add it to your schedule so that you are sure to get a seat. It may fill up…

Help Wanted – Logo for Snoop

Are you in possession of artistic and/or creative skills and want to contribute to an Open Source project?

Snoop is an open source service registry and discovery mechanism for Java EE based microservices that is in desperate need of a logo.

Have a look at and see if you can help.

Snoop in Swarm

If you want to run a Snoop enabled microservice in WildFly Swarm, you will need to add some more dependencies to get it to work. This is because Snoop relies on being run in a Java EE 7 compliant application server. And you will need to tell Swarm what parts you need to be able to run it.

In addition to the Swarm modules your microservice depend on, you will also need to add the following dependencies that Snoop requires:

The build section may be just as any swarm application:

Doing this will enable you to run your application as a JAR:

Snoop 1.0.0 Released


An explanation may be in order. Snoop is an experimental open source discovery service for Java EE that I created as a demo for my presentation at JavaLand earlier this year. After that I have developed it a little further and now I deem it good enough to be showcased more publicly.

The artifacts are published in Maven Central and has the following coordinates:

The Snoop Service is also available in Maven Central and for convenience available as a Docker image.

The GitHub project contains the source code as well as more documentation.

Tech Tip – Running Glassfish Nightly Builds in NetBeans

If you have tried adding a recent nightly build of GlassFish 4.1 to the server configurations in NetBeans, you may have come across the following problem:


The solution is as follows:
