5.3 Importing J2EE applications including resource adapters
You import J2EE applications including resource adapters.
Before importing J2EE applications, confirm that a resource adapter is not deployed with the same display name or the optional name as that of the resource adapter that is included in the J2EE application. If another resource adapter with the same display name or the optional name is deployed, you cannot import that J2EE application including the resource adapter. Note that you can use the same display name or the optional name as that of the resource adapters that are included in other J2EE applications.
Import the following J2EE applications:
-
J2EE applications in the archive format
The J2EE applications in the archive format contain the components of EJB-JAR, WAR, or RAR files under the working directory of a J2EE server. For details on importing J2EE applications in the archive format, see 8.1.1 Importing the J2EE applications that are in archive format.
-
J2EE applications in the expanded archive format
The J2EE applications in the expanded archive format are the J2EE applications containing the application entities such as EJB-JAR or WAR files in the files and directories that are external to the J2EE server, and follow fixed rules. However, the RAR files included in J2EE applications in the expanded archive format are saved in the archive format and not in the expanded file format. For details on importing J2EE applications in the expanded archive format, see 8.1.2 Importing the J2EE applications that are in exploded archive format.
