The glassfish-resources.xml file was modified during the database reverse engineering process to include the database connection pool and JDBC resources required by JPA. As a result, the contents of this file define the required GlassFish connection pool details.
It is important to understand that this file is used by NetBeans to dynamically configure the GlassFish server assigned to the project. In a real-world situation, the GlassFish server is configured by administrators and deploying a web application is done either from the command line or through the GlassFish administration console. You will not be deploying your application...
