Sun Java System Application Server 9.1 Application Deployment Guide

Naming Standards

Names of applications and individually deployed EJB JAR, WAR, and connector RAR modules must be unique within an Application Server domain. Modules of the same type within an application must have unique names. In addition, for entity beans that use CMP,.dbschema file names must be unique within an application.

If you do not explicitly specify a name, the default name is the first portion of the file name (without the .war or .jar extension). Modules of different types can have the same name within an application, because the directories holding the individual modules are named with _jar, _war and _rar suffixes. This is the case when you use the Admin Console or the asadmin command. See Tools for Deployment.

You can specify a name in one of these ways:

Make sure your package and file names do not contain spaces or characters that are illegal for your operating system.

Using a Java package-like naming scheme is recommended for module filenames, EAR filenames, module names as found in the <module-name> portion of the ejb-jar.xml files, and EJB names as found in the <ejb-name> portion of the ejb-jar.xml files. The use of this package-like naming scheme ensures that name collisions do not occur. The benefits of this naming practice apply not only to the Application Server, but to other Java EE application servers as well.

JNDI lookup names for EJB components must also be unique. Establishing a consistent naming convention might help. For example, appending the application name and the module name to the EJB name is one way to guarantee unique names. In this case, mycompany.pkging.pkgingEJB.MyEJB would be the JNDI name for an EJB in the module pkgingEJB.jar, which is packaged in the application pkging.ear.

If you are writing your own JSR 88 client to deploy applications to the Application Server using the following API, the name of the application is taken from the display-name entry in the Java EE standard deployment descriptor, because there is no file name in this case. If the display-name entry is not present, the Application Server creates a temporary file name and uses that name to deploy the application.

javax.enterprise.deploy.spi.DeploymentManager.distribute(Target[], InputStream, InputStream)

Neither the Admin Console nor the asadmin command uses this API.

Note –

Use of the following JSR 88 API is preferred. In this case, the name is derived from the file name as previously described.

javax.enterprise.deploy.spi.DeploymentManager.distribute(Target[], File, File)
