代码在Localhost中工作，但在使用hibernate的java在线网站中不起作用

我使用框架用Java制作了一个web应用程序——struts 2.0、hibernate 3.0和tiles 2.0。 在我的本地系统中，我使用JDK1.6、apache-Tomcat6.0和SQL5.5 当我注册用户时，它在本地主机上的本地系统中正常工作。 但当我注册时，它不能正常工作

我要做什么

在联机中重定向错误操作。但在本地主机上成功重定向操作记录添加成功并注册。

struts代码

<action name="registration" class="Registration" >

    <result name="input" >/registration.jsp</result>
    <result name="error" >/error.jsp</result>
    <result name="success" type="tiles" >home</result>
</action>

您是否在连接url中指定了正确的数据库地址？您发布的文件显示localhost。检查一下。

jdbc:mysql://localhost:3306/databasename 是的，我知道，但如何获取我的网站的数据库URL。。。？我不知道如何从web获取连接URL…..您的Ip:）请查看www.whatismyip.comOK谢谢您能给我详细的代码吗我需要编写什么来代替jdbc:mysql://localhost:3306/databasenamereplace 你的本地主机与你的ip:）是的，我知道，但如何获得我的网站的数据库URL。。。？我不知道如何从web上获取连接URL…您必须知道数据库的托管位置，对吗？您必须将该计算机的ip地址放在连接urlk中，我已将本地主机替换为我的网站ip。。。但它仍然没有在成功页面上重定向。我在上面提到的web服务器上得到了错误日志
