查看servlet版本,jsp版本

在java web开发中,查看servlet和jsp版本方法:

1、打开tomcat的安装目录,定位到common\lib目录,此目录下包含jsp-api.jar,servlet-api.jar[如果没有可能是没添加进来];

2、解压这两个文件,分别用记事本打开解压目录下的META-INF\MAINMEFT.MF文件;

3、servlet的版本信息:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.0
Created-By: 1.5.0_15-b04 (Sun Microsystems Inc.)
X-Compile-Source-JDK: 1.5

Specification-Title: Java API for Servlets
Specification-Version: 2.5
Specification-Vendor: Sun Microsystems, Inc.

4、jsp的版本信息:

Ant-Version: Apache Ant 1.7.0
