Tomcat 6.0 Jasper 异常
我一直在尝试让 tomcat 6.0 在我的本地计算机上运行，但没有成功。服务器正常启动，但是当我尝试查看页面时出现异常：
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

public void _jspInit() {
_el_expressionfactory = _jspxFactory.getJspApplicationContext(getServletConfig().getServletContext()).getExpressionFactory();
_jsp_annotationprocessor = (org.apache.AnnotationProcessor) getServletConfig().getServletContext().getAttribute(org.apache.AnnotationProcessor.class.getName());
}
I have been trying to get tomcat 6.0 to work on my local machine and have been unsuccessful. The server starts up normally, but when I try to view a page I get an exception:
SEVERE: Servlet.service() for servlet jsp threw exception
org.apache.jasper.JasperException: Unable to compile class for JSP:

检查 Web 应用程序中的库是否不包含 Tomcat 提供的任何内容。具体来说，请注意 JSP 和 JSP-EL 库。
这个问题让我想起了Ivy自动导入Tomcat并不喜欢的Spring JSP库和servlet库的情况。
Check that the libraries in your web application do not contain anything which Tomcat provides. Specifically, look out for JSP and JSP-EL libraries.
This problem reminds me of when Ivy was automatically importing the Spring JSP libraries and the servlet libraries which Tomcat really didn't like.
