一个简单程序，可是我始终调试不通过，帮我啊！ 我刚学JSP

错误信息如下：org.apache.jasper.JasperException: Unable to compile class for JSPAn error occurred at line: 14 in the jsp file: /action.jspGenerated servlet error:

解决方案 »

  1.   

    出错原因不是都告诉你了吗？
    比如第一个就是 'try' without 'catch' or 'finally'；
    使用try的话，至少要有一个catch或finally,
    你应该看的懂得啊
