WebWork 404页面未找到

冰雨中水 — Tue, 09 Jan 2007 02:14:00 GMT

把webwork-2.2.2.jar升级到webwork-2.2.4.jar和xwork-1.1.3.jar升级到xwork-1.2.1.jar为什么会出现404的错误，而且控制台抛出 WARN [http-8080-Processor25] VisitorFieldValidator.warn(104) | The visited object is null, VisitorValidator will not be able to handle validation properly. Please make sure the visited object is not null for VisitorValidator to function properly 请指教，谢谢！

hibernate 的left join

冰雨中水 — Sun, 10 Dec 2006 16:23:00 GMT

共有三个表，客户信息表，客户欠款表，客户还款表；客户欠款表与客户信息表是多对一个的关系，客户还款表与客户信息表是多对一关系，而客户欠款表与客户还款表没有做影射关系。现在要打出客户的欠款总额，和还款总额，我用left join查询还是没发查出想要的数据。不知各位有没有遇到这种需求。

DWR如何获得返回list中对象的参数

冰雨中水 — Wed, 06 Dec 2006 04:38:00 GMT

表a对表b是多对一的关系，通过DWR取出a的全部数据，返回的是一个list（alist），DWRUtil.addOptions（"bselect",data,"id","b.sn"）要将b中的sn数据显示在select下拉筐，但是这样拿出的是一个空白select，就是id有数据，b.sn显示空白。项目环境是spring+hibernate+webwork。

Unable to compile class for JSP

项目环境appfuse的spring+hibernate+webwork，更改了JSP文件名，为使以popup开始的页面不包含其他JSP页面，同时一个更改相应的XWORK文件，重新部署，重启服务后，在进入登录画面就出现如下异常（apache-tomcat-5.5.17）

native2ascii工具

冰雨中水 — Sun, 03 Dec 2006 16:02:00 GMT

资源文件的编码方式和编辑平台相关。在WINDOWS平台下编写的资源文件，以GB2312方式编码。在编译时需要转码，以确保在各个平台上的正确性: native2ascii [-encoding 编码] [输入文件 [输出文件]]这样从资源文件中读出的就是正确的UNICODE字符串。同时从UNICODE文件读取出GB2312格式的文件: native2ascii [-reverse] [-encoding 编码] [输入文件 [输出文件]]
