HTML5的標準化終于在2014-10-29日塵埃落定，正式發(fā)布了。

Servlet和JSP版本不斷向前進化，JDK也在進化中，提供了新的增強功能和特性。

Apache Tomcat Versions

Apache Tomcat is an open source software implementation of the Java Servletand JavaServer Pages technologies. Different versions of Apache Tomcat areavailable for different versions of the Servlet and JSP specifications. Themapping between the specifications and the respective Apache Tomcat versions is:

Jetty v9.1 feature：

Servlet API 3.1

- Async I/O
JSR-356 - javax.websocket support
Jetty WebSocket API - Streaming support Server Speed Improvements: - Shockingly fast response times New Async Http Client: - Our best yet, complete cleanup, faster than you can believe.
New Connector Architecture: - We are now 100% NIO, no more blocking I/O connectors. - We no longer have different connectors for different protocols. Now you have a ServerConnector, which supports all various flavors of connector configurations (http, https, ssl, spdy/2, spdy/3, etc). Specifically architected to support new fallback techniques and upcoming protocols (eg: http/2 when the spec is final)

Jetty v9.2 feature:

• 支持 Java 8

• 使用 Apache 版本的 Jasper 來處理 JSP/JSTL

• 異步 I/O 代理
• 異步 FastCGI
• ALPN (Application Layer Protocol Negotiation) 規(guī)范支持
• 多個Jetty base directories
