Core J2EE Patterns: Best Practices and Design Strategies
Over the last few years, Java 2 Platform, Enterprise Edition (J2EE) technology has emerged and matured as a standard platform for building enterprise applications. While the platform has matured into a solid offering for developing and deploying enterprise applications, it does offer its challenges. As developers, often we confuse learning the technology with learning to design with the technology. In this book, senior architects from the Sun Java Center, Sun's Java consulting organization share with the reader their cumulative design experience with and expertise on J2EE technology.
The primary focus of the book is on patterns, best practices, design strategies, and proven solutions using the key J2EE technologies including JavaServer Pages (JSP), Servlets, Enterprise Java Beans (EJB), and Java Message Service (J.M.S) API. Other ancillary technologies like JDBC and JNDI are also discussed as relevant to their usage in these patterns. The J2EE Patterns catalog with 16 patterns and numerous strategies is presented to document and promote best practices for these technologies.
In addition to the patterns and strategies, the book offers the following:

Using an EJB finder method to look up a large collection of entity beans will
return a collection of remote references. Consequently, the client has to invoke a
method on each remote reference to get the data. This is a remote call and can ...
Such lack of flexibility makes the application less manageable when changes are
required. When accessing the enterprise beans, clients interact with remote
objects. Network performance problems may result if the client directly interacts
The client requests the EJB home to provide a remote reference to the required
enterprise bean. The client then invokes business method calls on the remote
reference to access the enterprise bean services. All these method calls, such as
