Motivations to Standardize

• Reduction in support complexity

• Reduction in support costs

• Increased control of design and security

• Increased depth of understanding

• Code portability

Keep It Simple...

• Stick to the Java Servlet API, JSP’s, and JDBC

• Write Portable Code

• Use of EJB Technology Restricted

Product Selection

• Tomcat for Servlet and JSP[reference implementation of these standards]

• WebLogic for EJB [recommendation is for projects requiring Beans to

add on-going support costs]

• Other application servers only used when systems require and at cost to project for support.
