This post is the third in a series that covers the Java EE 5 to Java EE 6 migration of the JBoss Trading application (link).

This post covers the final configuration modifications required for the packaging covered in Part II (JAX-WS 2.2 & JPA 2.0).

Packaging

This is how the Java EE 6 version of the JBoss Trading application (link) is packaged.

  • JBoss Trading App (EAR)
    • JBoss Trading Beans (EJB JAR)
    • JBoss Trading Web (WAR)
      • JBoss Trading REST (JAR)
      • JBoss Trading Web Services (JAR)

Configuration

JBoss Trading Services

This module will be renamed as is it no longer contains JAX-RS and JAX-WS services.

  1. Rename JBoss Trading Beans (trading-beans).
  2. pom.xml (update) 
    <artifactId>trading-beans</artifactId>
<packaging>ejb</packaging>

<name>JBoss Trading Beans</name>

JBoss Trading EJB Client

    <dependency>
    <groupId>com.jboss.trading</groupId>
    <artifactId>trading-beans</artifactId>

    <type>ejb-client</type>
</dependency>

JBoss Trading REST

The JAX-RS services are packaged as a JAR, and are a dependency of the new JBoss Trading Web module.

    <artifactId>trading-rest</artifactId>
