Do you remember the good old Java Petstore ? It was a sample application created by Sun for its Java BluePrints program. The Java Petstore was designed to illustrate how J2EE (and then Java EE) could be used to develop an eCommerce web application. Yes, the point of the Petstore is to sell pets online.
We Recommend These Resources Performance problems are one of the biggest challenges to expect when designing and implementing Java EE related technologies. Some of these common problems can be faced when implementing either lightweight or large IT environments; which typically include several distributed systems from Web portals & ordering applications to enterprise service bus (ESB), data warehouse and legacy Mainframe storage systems. It is very important for IT architects and Java EE developers to understand their client environments and ensure that the proposed solutions will not only meet their growing business needs but also ensure a long term scalable & reliable production IT environment; and at the lowest cost possible. Performance problems can disrupt your client business which can result in short & long term loss of revenue.

This tutorial demonstrates how to use the IDE to create a web application that uses JavaServer Faces (JSF) 2.x and the Java Persistence API (JPA) 2.0 and then deploy the application to the Oracle WebLogic Server. In this tutorial you will register the WebLogic Server with the IDE, and then use wizards in the IDE to create a JDBC resource and entity and bean classes. You will then use the IDE to deploy the application to the server and register the new datasource.
