Struts2學習中 servlet,api的版本問題

1.  轉自http://hi.baidu.com/luo_qing_long/blog/item/c23c15f4adb73bdef2d385c7.html

我們在java web開發的過程中，有時在資料上可能會提到環境所要支持的JSP，Servlet版本。如果版本低就可能出現測試錯誤。

方法： 打開tomcat的common/lib 目錄下，有兩個JAR文件： jsp-api.jar servlet-api.jar 。如果沒有，那可能是你沒有添加進來。解壓這兩個文件，用記事本分別打開META-INF下的MAINMEFT.MF文件。

我的Servlet版本是：Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.5
Created-By: 1.4.2_12-b03 (Sun Microsystems Inc.)

Name: javax/servlet/
Specification-Title: Java API for Servlets
Specification-Version: 2.4
Specification-Vendor: Sun Microsystems, Inc.
Implementation-Title: javax.servlet
Implementation-Version: 2.4.public_draft
Implementation-Vendor: Apache Software Foundation

我的JSP版本是：Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.5
Created-By: 1.4.2_12-b03 (Sun Microsystems Inc.)

Name: javax/servlet/jsp/
Specification-Title: Java API for JavaServer Pages
Specification-Version: 2.0
Specification-Vendor: Sun Microsystems, Inc.
Implementation-Title: javax.servlet.jsp
Implementation-Version: 2.0.public_draft
Implementation-Vendor: Apache Software Foundation
