To assemble your application to run on your application server, use the runAssembler command-line script. This script takes a set of Oracle ATG Web Commerce application modules and assembles them into an EAR file (or the equivalent exploded directory structure).

The basic syntax of the command follows this format:

runAssembler earfilename –m module-list

For example, if you develop your application as an application module named MyApp, and you want to assemble an EAR file that includes your application plus the DSS and DPS modules, use the following command:

runAssembler MyApp.ear –m MyApp DSS

You do not need to specify the DPS module, because the application assembler examines the manifest file for each application module specified, and includes any modules that the specified modules depend on. The DSS module requires the DPS module, so it is included without being specified.

In addition to the modules containing core Oracle ATG Web Commerce functionality (such as the DSS module), you can also include Oracle ATG Web Commerce demos and reference applications in your EAR file. For example, to assemble an EAR file that includes the Quincy Funds demo, include DSSJ2EEDemo in the list of module for the runAssembler command.

When runAssembler creates an EAR file, unless otherwise instructed, it copies only CLASSPATH entries, the configuration path entries, and J2EE modules. To include other module files, specify them via the ATG-Assembler-Import-File attribute in the module’s META-INF/MANIFEST.MF file, as shown in this example from the DafEar.base module:

ATG-Required: DSS DAS-UI
ATG-Config-Path: config/dafconfig.jar
ATG-Web-Module: j2ee-components/atg-bootstrap.war
ATG-EJB-Module: j2ee-components/atg-bootstrap-ejb.jar
ATG-Class-Path: ../Tomcat/lib/classes.jar ../WebLogic/lib/classes.jar
  ../WebSphere/lib/classes.jar lib/classes.jar
Name: ../WebLogic
ATG-Assembler-Import-File: True

In addition, to include a standalone WAR file in an application you must provide runAssembler with the WAR file’s URL and context root. If not provided, runAssembler creates a unique name based on the directory where it found the WAR file. To provide the URL and context root, within your WAR file, create a META-INF/MANIFEST.MF file as follows:

Manifest-Version: 1.0
ATG-Enterprise-Nucleus: True
ATG-Module-Uri: atg_bootstrap.war
ATG-Context-Root: /dyn
ATG-Assembler-Priority: -1

For a list of modules included in the Oracle ATG Web Commerce installation, see Appendix D, ATG Modules. This appendix also contains information about how to access the demos and reference applications.

You can also include ATG Dynamo Server Admin in your EAR file, so you can monitor and change settings in your application. See the Including ATG Dynamo Server Admin section later in this chapter for information.
