Calling the compile target now creates the file HttpUnitTest.class in the appropriate directory, so we are ready to run the tests as soon as the web application is deployed.

Presentation layer The user interface logic is topmost. Code responsible for the presentation and control of page and screen navigation is in the presentation layer. Business layer The exact form of the next layer varies widely between applications. It s generally agreed, however, that the business layer is responsible for implementing any business rules or system requirements that would be understood by users as part of the problem domain. This layer usually includes some kind of controlling component code that knows when to invoke which business rule. In some systems, this layer has its own internal representation of the business domain entities, and in others it reuses the model defined by the persistence layer. We revisit this issue in chapter 3. Persistence layer The persistence layer is a group of classes and components responsible for storing data to, and retrieving it from, one or more data stores. This layer necessarily includes a model of the business domain entities (even if it s only a metadata model). Database The database exists outside the Java application itself. It s the actual, persistent representation of the system state. If an SQL database is used, the database includes the relational schema and possibly stored procedures. Helper and utility classes Every application has a set of infrastructural helper or utility classes that are used in every layer of the application (such as Exception classes for error handling). These infrastructural elements don t form a layer, because they don t obey the rules for interlayer dependency in a layered architecture.

Preparing to run HttpUnit tests from Ant Before executing our tests from Ant, we need to find the right place in the build file for them. The application must be deployed first, so they are dependent upon the deployment tasks. Because the main webapp/build.xml file is getting a bit large, we first pull out all the deployment routines we wrote in chapter 7 into a separate deploy.xml build file, which we call from the main build file with <ant>. A deploy target in build.xml hands off the deployment to the subsidiary file:

Let s now take a brief look at the various ways the persistence layer can be implemented by Java applications. Don t worry we ll get to ORM and Hibernate soon. There is much to be learned by looking at other approaches.

The setPropertyValue() method sets the value of an individual property of the MonetaryAmount. The initialPrice property now maps to two columns, so you need to declare both in the mapping file. The first column stores the value; the second stores the currency of the MonetaryAmount:

<target name="deploy" depends="dist"> <ant dir="." antfile="deploy.xml" target="default" inheritall="false"/> </target>

<property name="initialPrice" type="persistence.MonetaryAmountCompositeUserType"> <column name="INITIAL_PRICE"/> <column name="INITIAL_PRICE_CURRENCY"/> </property>

In the deploy.xml file, we create a default entry point that initially deploys to a local Tomcat server:

If Item is mapped with annotations, you have to declare several columns for this property. You can t use the javax.persistence.Column annotation several times, so a new, Hibernate-specific annotation is needed:

<target name="default" depends="deploy-localhost-remotely" description="deploy to a local tomcat4 server" />

@org.hibernate.annotations.Type( type = "persistence.MonetaryAmountUserType" ) @org.hibernate.annotations.Columns(columns = { @Column(name="INITIAL_PRICE"), @Column(name="INITIAL_PRICE_CURRENCY", length = 2) }) private MonetaryAmount initialPrice;

In a Hibernate query, you can now refer to the amount and currency properties of the custom type, even though they don t appear anywhere in the mapping document as individual properties:
