A: For Seam 1.2: Since Seam requires the latest edition of EJB3, you need to install JBoss AS from the latest
JEMS installer. Make sure that you select the “ejb3″ or “ejb3+clustering” profile to include EJB3 support. Also, the
jboss-seam.jar library file from the Seam distribution must be included in each Seam application you deploy. Refer to examples in Seam distribution (inside the
examples directory) to see how to build and package Seam applications.
A: Yes, you can run Seam applications in plain Tomcat 5.5+ or in the Sun GlassFish application server. To run Seam application in Tomcat, you need a number of additional library files and a few configuration files to bootstrap the JBoss EJB3 inside Tomcat. Please refer to the
deploy.tomcat ANT build target for the Seam
booking example (in the
examples/booking directory of the
Seam distribution) for more on how to build a Tomcat WAR for Seam applications. Refer to this blog post on how to run Seam in Sun’s Glassfish application server.
A: Yes, as of Seam 1.1, you can use Seam in any J2EE application server, with one caveat: you will not be able to use EJB 3.0 session beans. However, you can use either Hibernate or JPA for persistence,
and you can use Seam JavaBean components instead of session beans.
Please use the Seam User’s discussion forum for user questions.
A: Yes, Prentice Hall’s “JBoss Seam:
Simplicity and Power Beyond Java EE 5.0″ is a comprehensive guide for Seam written by JBoss insiders.
Seam only supports JSF as a view framework at this time. We plan to support other web rameworks in the future. We like JSF because it is a component-based UI framework, which fits really well with Seam’s component-based approach to business objects and persistence objects. Seam made a major improvement to JSF by eliminating almost all XML configuration for backing beans — you can now define back beans from POJOs or EJB3 components using simple annotations. We recommend you use Facelets, instead of JSP, with JSF. Facelets provide a powerful templating framework, better appplication performance, and allows us to write much simpler JSF pages. Please see the Seam
booking example application for an example on how to use Facelets.

Finally, Seam’s concurrency model is designed especially for use with Ajax.
Yes, Seam provides its own integration test framework based on TestNG. You can easily mock all Seam services
using those facilities without ever loading an application server or a database. Refer to the
testexample ANT target in the Seam
booking example application for more details.
