This chapter describes the steps required to getting started with the Seam Validation Module.

74.1. Prerequisites

Not very much is needed in order to use the Seam Validation Module. Just be sure to run on JDK 5 or later, as the Bean Validation API and therefore this Seam module are heavily based on Java annotations.

The recommended way for setting up Seam Validation is using Apache Maven. The Seam Validation Module artifacts are deployed to the JBoss Maven repository. If not yet the case, therefore add this repository to your settings.xml file (typically in ~/.m2/settings.xml) in order to download the dependencies from there:

Example 74.1. Setting up the JBoss Maven repository in settings.xml


...

<profiles>

    <profile>

        <repositories>

            <repository>

                <id>jboss-public</id>

                <url>http://repository.jboss.org/nexus/content/groups/public-jboss/</url>

                <releases>

                    <enabled>true</enabled>

                </releases>

                <snapshots>

                    <enabled>false</enabled>

                </snapshots>

            </repository>

        </repositories>

    </profile>

</profiles>



<activeProfiles>

    <activeProfile>jboss-public</activeProfile>

</activeProfiles>

...

General information on the JBoss Maven repository is available in the JBoss community wiki, more information on Maven's settings.xml file can be found in the settings reference.

Having set up the repository you can add the Seam Validation Module as dependency to the pom.xml of your project. As most Seam modules the validation module is split into two parts, API and implementation. Generally you should be using only the types from the API within your application code. In order to avoid unintended imports from the implementation it is recommended to add the API as compile-time dependency, while the implementation should be added as runtime dependency only:

Example 74.2. Specifying the Seam Validation Module dependencies in pom.xml


...

<properties>

    <seam.validation.version>x.y.z</weld.version>

</properties>



...



<dependencies>    

    ...

    <dependency>

        <groupId>${project.groupId}</groupId>

        <artifactId>seam-validation-api</artifactId>

        <version>${seam.validation.version}</version>

        <scope>compile</scope>

    </dependency>

    <dependency>

        <groupId>${project.groupId}</groupId>

        <artifactId>seam-validation</artifactId>

        <version>${seam.validation.version}</version>

        <scope>runtime</scope>

    </dependency>

    ...

</dependencies>

...

Note

Replace "x.y.z" in the properties block with the Seam Validation version you want to use.

74.3. Manual setup

In case you are not working with Maven or a comparable build management tool you can also add Seam Validation manually to you project.

Just download the latest distribution file from SourceForge, un-zip it and add seam-validation.jar api as well as all JARs contained in the lib folder of the distribution to the classpath of your project.
