JBoss Seam is one of Java's ways of providing agile development to enterprise Java applications. Seam is designed to take away the headache of linking JSF, EJB3, AJAX, and jBPM by using interception directed by user defined annotations. The end result is smooth and easily manageable code without the plumbing usually required for functionality. This session will take you through the process of how Seam works, creating a sample application, and what Seam can buy you for enterprise setup including the pros and cons.

Ever since the J2EE spec was released people have been writing code to cope with the awkwardness of a specification written by tool vendors for tool vendors. Generally this involved implementing patterns, writing wrappers, and writing custom frameworks to handle what should have been part of the specification. Resumes began to be cluttered with items like ?service locator pattern? and ?front controller pattern? experience. As needs grew so did the Java Community and they responded accordingly. Frameworks like Spring and Hibernate grew out of need and necessity to accommodate what was lacking. However, one area has been constantly lacking in enterprise applications is the glue to bring it all together. Seam grew out of this need to seamlessly, no pun intended, tie different components and Java frameworks together. What started out as simple glue for EJB3 ? JSF has grown rapidly and with fanfare. Not only was it used to glue presentation to business tier but many other components as well like mail, rules engines, PDFs and now one can even write Seam beans in Groovy. In this presentation we will go over what Seam is and what Seam can offer a development team. Seam can solve problems that normally required custom frameworks. While custom frameworks are always fun to develop, they take up resource time and can bring in another area of instability to the application. Whether your application is a simple web store or a complex enterprise application Seam can be used to cut development time down, and let your developers focus on the items that count: the business logic, the presentation, and your domain structure.

Vital to any development is the ability to test that application. Most frameworks have their very own testing suites, EJB3 is no exception and their are a variety of testing apparatuses. We will examine testing with JBoss Embedded, EJB3Unit and mocking with Easy Mock and JMocks.

Testing with EJB3 produces new issues that most developers have not seen locally. For one thing, their are generally no DAO's when dealing with Java Persistence API. Because of this it makes whats normally called integration or container testing more valuable even at the unit level, since no other piece of the application will be testing them directly. In this session we discuss two of the major ways to perform integration testing. The first is through a light container called EJB3Unit. This is an easy to set up testing framework that uses HSQL as the underlying database. However, EJB3Unit is more of a cross between unit and integration testing, for full on Integration testing we will use JBoss Embedded to get a richer feel. In addition, when using the integration frameworks is not as necessary, or when you need to add some mock testing to your EJB3Unit tests we will discuss two mock frameworks. The first are EasyMocks, the second is a newer framework that allows a bit more versatility called JMockIt. By the end of this you should be ready to go and test your EJBs thoroughly.

This presentation is designed to give users an introduction to what Grails has to offer. The presentation will show how fast one can get up and running with Grails.

For the last decade we have been trying to get web application development performed faster and faster. Struts was the first Java web application that had wide spread adoption to start to get web application development faster. Of course years later we realized it was still quite slow. Along the way came items like Spring, Hibernate, Ruby on Rails, and finally Groovy. All of these pieces together, and quite a bit of hard work from many people helped to bring together into the framework we know as Grails.

This presentation will show how one can create a web application that meets all your needs much faster and more agile than before with Grails. We will cover the basics of starting from scratch, creating your models, views, and domains to have a fully built application in the end.
