An enterprise application archive (EAR) can consist of many sub modules. The sub modules can be web modules (WAR), ejb modules (JAR), resource adapter modules (RAR) or application client modules (jar). When an EAR consist of many sub modules, the deployment plans for all the sub modules can be provided in a single file named geronimo-application.xml. This single file contains the deployment details of each of the sub modules of the EAR. Alternatively, each of the sub modules can package its corresponding deployment plan file within itself. However, the preferable way is to provide a single deployment plan through geronimo-application.xml for all the sub modules. This mechanism provides flexibility of allowing us to modify the deployment configuration for all modules through a single file. In this section, we explore EAR deployment plan and understand what it contains.

There are 3 places a deployment plan (partial plan ) can be associated for with an ear, and they are used in this order: 1. external plan So, anything in an external plan takes precedence over bits in (2) or (3) configuring the same module. Anything in (2) takes precedence over a module level plan. If a module level plan is missing from (1) its looked for in (2),then (3); if missing from (1) and (2), then its looked for in the module (3). There is no attempt to merge plans from these different locations: e.g. if there's something in (1) for a module, any other plans are ignored. |
