关于TOMCAT一个很奇怪的问题！

我以前碰到过这种情况是因为使用了<html:form>，在显示到一半的时候，会白页
改为普通的<form>,问题解决

解决方案 »

  1.   

    执行到一句HTML语句就停止了，即便HTML语句有错，代码也会继续往下执行啊，更何况没有错。
      

  2.   

    对了，我页面里没有使用form标签
      

  3.   

    你又没说什么Exception，那些Log信息都不给，这样叫别人猜 ，别人怎么可能知道。
      

  4.   

    没有任何异常啊，代码页面执行正常，就是执行到这句HTML语句，读到第三个字节处不往下读了，我是查看页面源文件发现的
      

  5.   

    就是你文件的问题，不可能是tomcat的错误，我遇到N次了
      

  6.   

    那是我文件哪里错了？这是文件源代码：
