执行的时候报错:
org.apache.jasper.JasperException: Exception forwarding for name indexToMain: javax.servlet.ServletException: could not execute query
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:510)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:375)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

我以前也经常碰到这个问题``
但是我不太记得是什么原因引发的
` 不过这个异常可以有很多的东西引发``
你这个异常的关键是 Exception forwarding for name indexToMain 这个东西

下载 安装补丁了没有！

indexToMain 检查action里面的forwarding
