Developing lightweight J2EE client applications that interoperate with multiple application servers can be difficult to do. Having to include an application server-specific JAR file along with a thin client application can significantly increase the size of the deployed application and make it too big to be practical. In addition, client-side execution is tightly coupled using proprietary app-server extensions. This is especially true when mixing and matching multiple J2EE vendors together (such as a Tomcat servlet container communicating with a WebLogic EJB tier). Standard protocols, such as RMI/IIOP, are supposed to alleviate this problem. However, there is still no standard API or library that can be used across application servers without sacrificing native features, such as: Clustering and high availability (including load balancing and failover) Native commu...

Implementing a Cluster-Aware Cache Using WebLogic

Caching information on the WebLogic tier can significantly increase performance and reduce the number of external system calls needed for data retrieval. This is especially true when an application wants to store bits of information that rarely change, such as a list of countries or catalog entries. Nowadays, memory is so cheap that application architectures can benefit from caching data on the Web/EJB tiers. This is not a new concept; most developers already do this. Whether it's accessing data from a simple java.util.Hashtable or java.util.Hashmap, or using a sophisticated LRU... (more)

Scaling AJAX Applications Using Asynchronous Servlets

The advent of AJAX as a Web application model is significantly changing the traffic profile seen on the server side. The typical Web pattern usage of a user sitting idle on a Web page filling out fields and hitting the submit button to the next link is now transforming into sophisticated client-side JavaScript and rich user interfaces that constantly communicate with the server whenever an event is posted on a form such as a checkbox click, key press, or tab focus. Think about the amount of data transmitted from the client to the server. From a usability standpoint, the user ge... (more)
