The Jakarta Apache Project has released version 5.5.17 of the Tomcat open source servlet container and official reference implementation of the Java Servlet API 2.4 and Java Server Pages (JSP) 2.0. This beta is mostly a bug fix release as detailed in the change log." "Tomcat 5.5 is designed to run on J2SE 5.0 and later, and requires configuration to run on J2SE 1.4....In addition, Tomcat 5.5 uses the Eclipse JDT Java compiler for compiling JSP pages. This means you no longer need to have the complete Java Development Kit (JDK) to run Tomcat, but a Java Runtime Environment (JRE) is sufficient. The Eclipse JDT Java compiler is bundled with the binary Tomcat distributions. Tomcat can also be configured to use the compiler from the JDK to compile JSPs, or any other Java compiler supported by Apache Ant."
