Answer 1

错误信息已经说的很清楚了，
org.apache.jasper.JasperException: /pages/admin/login.jsp(19,0) Attribute id invalid for tag form according to TLD是JSP解析时出错了，Attribute id invalid for tag form according to TLDlogin.jsp中   id   是什么东东？

Answer 2

/pages/admin/login.jsp(19,0）把第19行贴上来看看

Answer 3

这是JSP，是编译后的第19行。
