This recipe adds a new target to the build.xml file. The jar_ejb target sets up and executes the JAR tool against the newly created class files (from the compile command). Notice, in fact, that it depends on the compile_ejb target before it executes. This ensures that class files are present for the JAR tool. Before setting up the <fileset> tag, the target copies all available EJB XML files into a META-INF folder under the build directory. Next the <fileset> tag tells the target where to find the class files for the JAR tool. Finally, the <jar> command builds a JAR file named after the project.

Java EE defines a standard way of packaging these modules in JAR files, and specifies the formats for these JARs One of the advantages of having these formats defined as part of the specification is that they are portable across application servers..

Table 11.1 lists the archives or modules supported by Java EE 5 and their contents. Note that each archive type is used for packaging a specific type of module, such as EJB or web. For instance, a WAR is used to package a web-tier application module, and the EAR file is intended to be the ber archive containing all the other archives so that in the end, you re only deploying one file. The application server will scan the contents of the EAR and deploy it. We discuss how an EAR is loaded by the server in section 11.1.2.

Having established that code scattering occurs, it is normal to ask whether you could eliminate the problem by composing the class structure differently or designing the application in another way. The main reason that code scattering occurs has to do with the differences in the way that a service is made available and the way that it is used. A class gives access to one or more services through its methods. It is relatively easy to group the available services together in the same place in other words, in the same class. However, once these services have been used from several classes, it is difficult to re-engineer the application to group the calls to those methods together. It is therefore not surprising that a fundamental and well-known service is called from all over the application. Code scattering is an effect that manifests itself in any complex program. However, the exact way it manifests itself depends on the application, the modeled concerns, the used libraries, and the frameworks. Because it heavily depends on a concrete problem, code scattering is difficult to remove. Code scattering in an application slows down the development, maintenance, and evolution of the program. When several functionalities are scattered, the situation worsens because the code starts to contain many calls to multiple concerns that are a priori loosely coupled but that need to be integrated together. This phenomenon is apparent in many applications.

After building class files from your EJB source files, you want to automate the generation of your EJB stub classes.

Table 11.1 Enterprise Java applications need to be assembled into specific types of JAR files before they can be deployed to an application server. These are the available module types as specified by Java EE. Type CAR Description Client application archives Enterprise application archive EJB Java archive Descriptor application-client.xml Contents Thick Java client for EJBs.

Other Java EE modules such as EJB-JARs. Session beans, message-driven beans, and optionally entities. Needs a persistence.xml if entities are packaged. Resource adapters.

Web application artifacts such as servlets, JSPs, JSF, static files, etc. Entities can also be packaged in this module. Needs a persistence. xml if entities are packaged.

After you generate the class file for your EJBs, you also need to generate the stub classes for deploying the beans into a specific EJB container. Generating stub classes requires you to run an EJB compiler tool provided by the vendor. This tool will generate stub source files and automatically compile them. Using Ant, you can automate the use of this tool.
