Apache TomEE

The goal of this example is to demonstrate how maven projects might be organized in a more real world style and how testing with OpenEJB can fit into that structure.

This example takes the basic moviefun code we us in many of examples and splits it into two modules:

business-logic
business-model

As the names imply, we keep our @Entity beans in the business-model module and our session beans in the business-logic model. The tests located and run from the business logic module.

ear-testing
ear-testing/business-logic
ear-testing/business-logic/pom.xml
ear-testing/business-logic/src/main/java/org/superbiz/logic/Movies.java
ear-testing/business-logic/src/main/java/org/superbiz/logic/MoviesImpl.java
ear-testing/business-logic/src/main/resources
ear-testing/business-logic/src/main/resources/META-INF
ear-testing/business-logic/src/main/resources/META-INF/ejb-jar.xml
ear-testing/business-logic/src/test/java/org/superbiz/logic/MoviesTest.java
ear-testing/business-model
ear-testing/business-model/pom.xml
ear-testing/business-model/src/main/java/org/superbiz/model/Movie.java
ear-testing/business-model/src/main/resources/META-INF/persistence.xml
ear-testing/pom.xml

Project configuration

The parent pom, trimmed to the minimum, looks like so:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

  <modelVersion>4.0.0</modelVersion>
  <groupId>org.superbiz</groupId>
  <artifactId>myear</artifactId>
  <version>1.1.0-SNAPSHOT</version>

  <packaging>pom</packaging>

  <modules>
    <module>business-model</module>
    <module>business-logic</module>
  </modules>

  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.apache.openejb</groupId>
        <artifactId>jakartaee-api</artifactId>
        <version>6.0-2</version>
      </dependency>
      <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.8.1</version>
      </dependency>
    </dependencies>
  </dependencyManagement>
</project>

The business-model/pom.xml as follows:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

  </parent>

  <modelVersion>4.0.0</modelVersion>

  <artifactId>business-model</artifactId>
  <packaging>jar</packaging>

  <dependencies>
    <dependency>
      <groupId>org.apache.openejb</groupId>

      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <scope>test</scope>
    </dependency>

  </dependencies>

</project>

And finally, the business-logic/pom.xml which is setup to support embedded testing with OpenEJB:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

  </parent>

  <modelVersion>4.0.0</modelVersion>

Test Code

The test code is the same as always:

public class MoviesTest extends TestCase {

    public void test() throws Exception {
        Properties p = new Properties();
        p.put(Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.core.LocalInitialContextFactory");

        p.put("openejb.deployments.classpath.ear", "true");

        p.put("movieDatabase", "new://Resource?type=DataSource");
        p.put("movieDatabase.JdbcDriver", "org.hsqldb.jdbcDriver");
        p.put("movieDatabase.JdbcUrl", "jdbc:hsqldb:mem:moviedb");

        p.put("movieDatabaseUnmanaged", "new://Resource?type=DataSource");
        p.put("movieDatabaseUnmanaged.JdbcDriver", "org.hsqldb.jdbcDriver");
        p.put("movieDatabaseUnmanaged.JdbcUrl", "jdbc:hsqldb:mem:moviedb");
        p.put("movieDatabaseUnmanaged.JtaManaged", "false");

        Context context = new InitialContext(p);

        Movies movies = (Movies) context.lookup("MoviesLocal");

        movies.addMovie(new Movie("Quentin Tarantino", "Reservoir Dogs", 1992));
        movies.addMovie(new Movie("Joel Coen", "Fargo", 1996));
        movies.addMovie(new Movie("Joel Coen", "The Big Lebowski", 1998));

        List<Movie> list = movies.getMovies();
        assertEquals("List.size()", 3, list.size());

        for (Movie movie : list) {
            movies.deleteMovie(movie);
        }

        assertEquals("Movies.getMovies()", 0, movies.getMovies().size());
    }
}
