- Tomcat Java Servlets
J2SE SDK is maintained by the Sun Developer Network (http://java.sun.com/javase/technologies/core/index.jsp) and is

provide Java Servlet Technology and Java Server Pages Technologies. Tomcat is maintained by the Apache Software
Foundation, developed under the terms of the Java Community Process, and is distributed under the terms of the

This release enhances support for the Java 2 Platform by providing custom installation scripts (vinstall) and

Many Java applications consume significant CPU and memory resources and may not be appropriate for use on a VPS.
Java applications on a VPS should be restricted for use only on Web sites with a low expected workload. In addition,
some larger Java applications may not be suitable for use on a VPS even with low workloads. You must conduct
sufficient performance testing of your Java application on a Linux VPS account before you rely on the it for
critical business needs. You must build contingency plans in case your Java application does not perform as
expected; alternative solutions may include:
- Extensive optimization of the Java application
- Moving the Java application to a dedicated server such as the Managed Private Server (MPS).
- Implementing an alternative solution to using Java. For example, if you move away from Java to an
optimized C program.
