We also provided a simple test applet to call the EJB for preliminary testing. However, we still need to review the process of setting up a servlet client into the EJB. Servlets, like EJBs, are a core piece of the overall J2EE suite of technologies. As mentioned in Part 1, servlets provide a very scalable approach to deploying dynamic Web sites. This is because they're generally instantiated only once to serve all clients. The first servlet will then support all subsequent inc... (more)

Developing EJBs and Servlets for EAServer

As many readers know, Sybase is one of the first licensees of the Java 2 Platform, Enterprise Edition from Sun Microsystems. J2EE promises to become the dominant industry model for quickly developing, enhancing and deploying mission-critical e-business applications.While portability is the most well-known of Java's attractions, the J2EE technology suite also provides a robust framework for reliable, scalable and secure applications. As J2EE is largely targeted at mission-critical enterprise applications deployed to the middle tier, Sybase's powerful EAServer product is a natural ... (more)
