EAServer 4.1 has new features to simplify the deployment of applications to EAServer:
When using Jaguar JAR format archives to deploy between EAServer installations, you can include merge files. A merge file allows you to modify or delete settings for entities that already exist. For example, you can create a merge file to install a package into the Jaguar server, without affecting the list of packages that are already installed.
When using J2EE standard archive formats such as an EJB-JAR file, an application EAR file, or a Web application WAR file, you can define an EAServer supplemental deployment descriptor to configure properties that are required by EAServer but are not supported by the standard deployment descriptor format. EAServer creates a supplemental descriptor for any archive that you export from EAServer Manager.
For more information on these features, see Chapter 9, “Importing and Exporting Application Components,” in the EAServer System Administration Guide.
