tomcat启动的时候报 validateJarFile jar not loaded 异常详细信息： validateJarFile(xxx\WEB-INF\lib\servlet.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class 最近做项目要用到tomact服务器调试,本来一切正常.可是当我再次导入工程到tomact时出现错误. 如下: 2010-4-4 13:57:38 org.apache.catalina.loader.WebappClassLoader validateJarFile
信息: validateJarFile(D:/Program Files/Apache Software Foundation/Tomcat 6.0/webapps/triffic/WEB-INF/lib/javax.servlet.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class 先不理他,运行工程,在ie中输入http://192.168.1.6:8585/triffic/ ie中出现的错误是: type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception javax.servlet.ServletException: java.lang.NoSuchMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletContext;)Ljavax/servlet/jsp/JspApplicationContext;

at java.lang.Thread.run(Thread.java:619) 解决方式: D:/Program Files/Apache Software Foundation/Tomcat 6.0/webapps/BS/WEB-INF/lib 把那个 javax.servlet.jar javax.servlet.jsp.jar 删除即可！ I'm trying to running this on Tomcat
and get the following error.
Jun 18, 2004 5:18:05 PM org.apache.catalina.loader.WebappClassLoader
validateJarFile
INFO: validateJarFile(D:/Program Files/Apache Software Foundation/Tomcat 6.0/webapps/BS/WEB-INF/lib/javax.servlet.jar)
- jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending
class: javax/servlet/Servlet.class
If any one could help on this, I would be realy grateful. regards Handan Details: 把 webapps/maintenance/WEB-INF/lib/
下面的 servlet-api.jar 删掉吧！ tomcat自己有，不需要你提供！
顺便看看其他的jar, 和 tomcat/lib 目录比较一下，tomcat已经有的，就别留着了！ 这才想起，我在tomcat/common/lib/中也放入了j2ee.jar等包，去common/lib中处不必要的包后，保证tomcat/common/lib/和WEB-INF/lib这两个目录下的jar没有重复的，问题解决。
原来，tomcat 启动后先将tomcat/common/lib目录下的jar包全部读入内存，如果webapps目录里的应用程序中WEB-INF/lib目录下有相同的包，将无法加载，估计不同版本的包之间也会造成类似问题。因此建议尽量不要把jar包放入tomcat/common/lib目录下，应该放入WEB- INF/lib目录下。
