java - 部署java webservice时出错

Question

谁能帮我解决这个问题。

我使用 Java 1.6、tomcat-6.0.20 和 axis2-1.4.1 创建了简单的 java web 服务。

在部署应用程序时，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

似乎加载的库不兼容。

第一贴解释错误:

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 Any servlet.jar you find involved with this server would contain out of date classes for this server.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...检查您是否没有额外的 servlet.jar:

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.

希望对你有帮助。
