部署java webservice时出现tomcat错误

Question

有人能帮我吗

我使用Java1.6、tomcat-6.0.20和axis2-1.4.1创建了简单的JavaWeb服务

部署应用程序时，它返回以下错误消息：

SEVERE: Servlet.service() for servlet jsp threw exception
org.apache.jasper.JasperException: Unable to compile class for JSP: 

An error occurred at line: 22 in the generated java file
The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory

Answer 1

似乎加载的库不兼容

见本post和this

第一篇文章解释了错误：

In Tomcat 6, the JSP API classes are found in jsp-api.jar and servlet API classes are found in servlet-api.jar, with both located in the lib directory of the Tomcat 6 installation. Any servlet.jar you find involved with this server would contain out of date classes for this server.

所以。。。检查是否没有额外的servlet。罐子：

Make sure you don't have a copy of servlet.jar in the WEB-INF/lib of your webapp or somewhere else involved with the running server, such as in the lib/ext directory of your JDK or JRE.

我希望它能帮助你
