What is the relationship of the Apache Tomcat open-source application server and the Java EE SDK?
Tomcat is based on the original implementation of the JavaServer Pages (JSP) and Java Servlet specifications, which was donated by Sun to the Apache Software Foundation in 1999. Sun continues to participate in development of Tomcat at Apache, focusing on keeping Tomcat current with new versions of the specifications coming out of the Java Community Source Process(SM). Sun adapts and integrates the then-current Tomcat source code into new releases of the Java EE SDK.
