我在为tomcat 7.0 server启动localhost时遇到问题。 （ eclipse indigo，Java ）。以下是错误消息，服务器无法以 45ms 启动。有人可以解释一下我得到的这个错误吗？

谢谢。我能够修复web.xml但现在我得到了一个不同的错误。

2 个答案:

答案 0 :(得分：0)

检查此行：

Caused by: java.lang.IllegalArgumentException: 
  Invalid <url-pattern> CrystalReportViewerHandler in servlet mapping

您的web.xml包含servlet CrystalReportViewerHandler的无效映射。

纠正这一点，你会没事的。如果您不知道如何更正：发布web.xml snipplet。

答案 1 :(得分：0)

关于这条线; 

Caused by: java.lang.IllegalArgumentException: Invalid <url-pattern> CrystalReportViewerHandler in servlet mapping

在Web应用程序部署描述符中，以下语法用于定义映射：

  
      
  • 以“/”字符开头并以“/ *”后缀结尾的字符串用于路径映射。
    •   
  • 以'*。'前缀开头的字符串用作扩展名映射。
    •   
  • 空字符串（“”）是一个特殊的URL模式，它完全映射到应用程序的上下文根，即表单的请求   http://host:port/ /。在这种情况下，路径信息是'/'和   servlet路径和上下文路径是空字符串（“”）。
    •   
  • 仅包含'/'字符的字符串表示应用程序的“默认”servlet。在这种情况下，servlet路径是   请求URI减去上下文路径，路径信息为null。
    •   
  • 所有其他字符串仅用于完全匹配
    •   

如果您分享 web.xml ，我们可以给出具体答案。

如需参考，请查看Java Servlet Specification和此Servlet Configuration。
