一个ssh的问题

Question

看不出来，
在tomcat的work子目录下一直找到index_jsp.java:106行，看看有什么错

Answer 1

估计是到这句开始报错的 <html:form action="/tuser">
看下你的struts-config.xml是否写错.

Answer 2

javax.servlet.jsp.JspException: Exception creating bean of class com.accp.form: {1} 看看你的struts配置文件！
最好有更详细的错误信息！

又出现了以上的错误~~  不知道怎么回事，我再里面写值了啊 ，怎么他说是Null呢 

Answer 4

com.microsoft.sqlserver.jdbc.SQLServerException: 不能将值 NULL 插入列 'username'，表 'guojian.dbo.tuser'；列不允许有空值。INSERT 失败。 username为空，但是你数据库表里该字段设置为not null ，不准为空，所以insert不了

Answer 5

你可以insert前打印出来看一下，然后从前台走到后台顺一顺看看那里走空值的。

Answer 6

1:看看是不是页面的property和bean里的字段不匹配...
2:特别是你的username(应该就是这个错误index_jsp.java:106行,javax.servlet.jsp.JspException: Exception creating bean of class com.accp.form: {1} )
