The Geronimo deployment plan for an enterprise application is an XML document. It is defined by the geronimo-application-1.1.xsd schema, which can be found in the schema/ subdirectory of the main Geronimo installation directory. The deployment plan for an enterprise application can be included in the application EAR, in which case it should be named META-INF/geronimo-application.xml or saved as a separate file and provided to the deploy tool when the application is deployed

0 The Enterprise Application Geronimo Deployment Plan Overview
There is a specific internal structure for the Enterprise Application deployment plan for Geronimo and follow a specific structure and order of elements.
...
META-INF/geronimo-application.xml
...
...
The attributes are defined below
xmlns The main namespace for the deployment plan, which should always be http://geronimo.apache.org/xml/ns/j2ee/application-1.1
xmlns:sys A secondary namespace, used to identify the common elements for third-party libraries and custom services. If present, this should always be set to http://geronimo.apache.org/xml/ns/deployment-1.1
xmlns:security A secondary namespace, used to identify the common elements for security role settings. If present, this should always be set to http://geronimo.apache.org/xml/ns/security-1.1
2.Class Path Settings for Enterprise Application Deployment Plan
...
Any Module The module's entire Geronimo deployment plan may be embedded in the EAR deployment plan at this location. It should use the same elements and namespaces as normal. Note that this is commonly used by JSR-88 deployment tools (which must save a single deployment plan for the application and all its modules), but is used less frequently for handcrafted deployment plans.

0 Work out Geronimo Deployment plan
This section will be discussed the details of how Geronimo deployment plan for EAR has implemented for different type of applications accordingly.The Sample Application section of the Geronimo user guide has been heavily used to discusses the deployment plan in depth.
...
The article deployment plan level-1 gives an primary understand to the user in basics of Geronimo v1.1 specific deployment plan for an EAR and go head to work with complex applications.Further details about application can be find the original location as at http://cwiki.apache.org/GMOxDOC11/deployment-plans-level-1.html.Therefore here are deployment plans used in this sample application.
Geronimo requires that every EAR file has a standard META-INF/application.xml deployment descriptor. This may be configured for J2EE 1.2, J2EE 1.3, or J2EE 1.4, and should follow the appropriate XML format and following is the application.xml for the above application.
...
This deployment plan define the war module in <web><web-uri>helloworld.war<web-uri> and the root context of it.The geronimo-application.xml is the geronimo specific plan for above application.
...
...
3.2 Sample Code for the Configuring modules*
This sample has been taken from the user guide, Sample application.http://cwiki.apache.org/GMOxDOC11/jms-and-mdb-sample-application.html.This is a sample deployment plan for A context root for web application module with a ejb application.
...
In this case, the EJB deployment plan is stored inside the EAR and it is compressed with Order.jar inside META-INF/openejb.xml and ejb-jar.xml . The Web application deployment plan is actually right there inside the EAR deployment plan,compressed with Orderweb.war/WEB-INF/web.xml and geronimo-web.xml.Also the EAR deployment plans both are directly stored right in side the Order.ear/META-INF/application.xml and geronimo-application.xml

3.3 Sample code for Adding a new module
This sample application uses a connector module in the deployment plan itself.This sample code for geronimo-application and the application.xml has been excerpt from user guide, sample application located at http://cwiki.apache.org/GMOxDOC11/ejb-sample-application.html
Therefore addition to configuring modules listed in application.xml, the Geronimo plan can add references to new modules, either in the EAR or located in the Geronimo repository.
...
...
geronimo-application.xml and application.xml define the main components of the EAR. Both EJB component and Web archive information are given in these files. Additionally, these two XML files define application scoped database connection pool with tranql-connector-1.2.rar and BankPool.xml.
