Introduction to modern Batch and computational-intensive programming models Brief introduction A batch process is a traditional and indispensable component of any enterprise IT domain. The current batch development trend is to apply internal Java skills to online programs and batch programs to ensure that: Maximize the reuse of implementations. Easier development and maintenance because the same toolset is used. Consistency in the implementation

design--a unified Modeling Language (Unified Modeling Language, UML) deployment diagram that describes the phone book client application, as shown in Figure 1. The client application connects to Geronimo through its EJB port and talks with the phonebook session EJB to manipulate the data in the database through phonebook Entry container-managed Persistence (CMP) 。 Figure 1.

Why is Jboss used? 1. Jboss supports hot deployment. It automatically loads and updates the archived JAR and WAR files under the deployment directory.2. In high-concurrency access, the performance is better and more efficient than Tomcat.3. Compared with Tomcat, Jboss optimizes the thread pool and connection pool.4. Jboss has become an enterprise-level Web Application of Java middleware. Tomcat is a lightwe
