SSH项目中的一个非常规的404错误！

[wolf_in_darkness]

项目部署运行没有任何错误，对于JSP页面文件照常访问，就是以遇到需要表单处理的页面就出现可恶的404错误！我对于可能出错的地方已经进行了检查，结果发现
1.、web.xml文件中配置ActionServlet没问题
2、struts-config.xml文件中配置要访问的Action没问题
3、jsp文件form标记中action属性的路径名称也没问题。
4，察看Tomcat下logs目录下的localhost_log文件，发现好几个错误：

为这个问题头疼两天了，请大侠指点迷津！为了节省大家的时间，我附上关键配置信息如下：

在spring 里面好好查查.里面有的东西找不到.或者写错都会导致404

[傻根她弟]

如果配置文件没有问题，那么最大的可能是导入包版本问题

[li_d_s]

Error creating bean with name 'sessionFactory' defined in ServletContext resource

=========================
'sessionFactory' 这个bean的定义部分

[lihaibo168]

你把form里面的action的路径写全路径
比如
<form action="/项目名/actionName.do" method="post">
</form>

楼主用的是Hibernate3.1的版本吗？如果是的话，那就看你导包的顺序了，
如果是Struts->Spring->Hibernate的话，那你导Spring的时候有个弹出对话框，你点中间那个replace按钮，最后导Hibernate就点第一个按钮

如果你用的是Hibernate3.0的版本，就按Struts->Hibernate->Spring的顺序添加，这里Hibernate和Spring的对话框都点第一个按钮

应该是这个问题吧，我以前也经常出现这个问题的

[一板砖夯死你]

Cannot convert value of type [java.lang.String] to required type [javax.sql.DataSource] for property 'dataSource': no matching editors or conversion strategy found

数据类型转换错误~~~

谢谢个位朋友了!前段时间出差,一直没空上网,对不住了.这个问题已经解决了,正如6楼的兄弟所说,希望大家以后也吸取教训,我也会及时上来跟大家一起交流的.

真的是倒包的问题吗？
我都不清楚是咋个回事了...哎，还有人能帮帮忙么？
我倒包是按--hibernate3.1 spring2.0 的顺序也是出一样错误。
