Chapter 41. Dependencies

Seam does not work with JDK 1.4 and requires JDK 5 or above as it uses annotations and other JDK 5.0 features.. Seam has been thoroughly tested using Sun's JDKs. However there are no known issues specific to Seam with other JDK's.

41.1.1. Sun's JDK 6 Considerations

Earlier versions of Sun's JDK 6 contained an incompatible version of JAXB and required overriding it using the "endorsed" directory. Sun's JDK6 Update 4 release upgraded to JAXB 2.1 and removed this requirement. When building, testing, or executing be sure to use this version or higher.

Seam used JBoss Embedded in its unit and integration testing. This has an additional requirement when using JDK 6. In order to run JBoss Embedded with JDK 6 you need to set the following JVM argument:

-Dsun.lang.ClassLoader.allowArraySyntax=true

Seam's internal build system is setting this by default when it executes Seam's test suite. However if you are also using JBoss Embedded for your testing you will need to set this value.

41.2. Project Dependencies

This section both lists the compile-time and runtime dependencies for Seam. Where the type is listed as ear, the library should be included in the /lib directory of your application's ear file. Where the type is listed as war, the library should be placed in the /WEB-INF/lib directory of your application's war file. The scope of the dependency is either all, runtime or provided (by JBoss AS 4.2).

Up to date version information and complete dependency information is not included in the docs, but is provided in the /dependency-report.txt which is generated from the Maven POMs stored in /build. You can generate this file by running ant dependencyReport.

41.3. Dependency Management using Maven

Maven offers support for transitive dependency management and can be used to manage the dependencies of your Seam project. You can use Maven Ant Tasks to integrate Maven into your Ant build, or can use Maven to build and deploy your project.

We aren't actually going to discuss how to use Maven here, but just run over some basic POMs you could use.

Released versions of Seam are available in http://repository.jboss.org/maven2 and nightly snapshots are available in http://snapshots.jboss.org/maven2.

All the Seam artifacts are available in Maven:


<dependency>

  <groupId>org.jboss.seam</groupId>

  <artifactId>jboss-seam</artifactId>

</dependency>


<dependency>

  <groupId>org.jboss.seam</groupId>

  <artifactId>jboss-seam-ui</artifactId>
