About this class Move beyond the basics of developing a Java application into the following areas: Java and distributed objects, Java security, integrating Java with databases and messaging systems, performance, and testing. Note: - This course does not cover servlets, JavaServer Pages (JSP), or Enterprise JavaBeans (EJB).
Who will the lesson benefit? This is an advanced course for experienced Java developers, who want to obtain more advanced server-side developer skills. What delegates will learn - Define services and Application Programming Interfaces (API) used for developing distributed Java applications.
- Describe design patterns used to create reusable Java classes for server-side programming
- Develop and design classes to utilize Java integration to databases
- Describe the Java 2 platform security model
- Examine the many alternatives in the ways that exceptions can be used and subclassed for particular applications
- Set locale using the Locale class
- Describe some considerations in server application construction
