而在网页发布中能显示页面链接不到数据库，而sp4补丁也打了，jdbc驱动也装了

Answer 1

估计还是数据库的问题，你的其它项目能连接上面吗？我的和你的差不多，也是连接不上数据库，还是在装SQL的时候没选择SQL和Windows身份验证，应该是两个都选的，默认选了Windows身份验证，再装的时候改过来就可以了！

Answer 2

看看ActionForm跟表单提交参数有没有对应上，如果JSP页面里有ActionForm中没有的参数的话会报异常的...
回答对了
如果你 action-config.xml中的action 有配置name的话 就该有个 formbean ，没有就错了。
