SSH2 开启客户端校验出错
本帖最后由 papaxiong7658 于 2012-11-18 16:15:39 编辑 SSH2框架，弄了一个客户注册的例子，注册时输入的信息进行校验，不使用客户端校验时没有问题，一开启客户端校验，进入regist.jsp页面时就报FreeMarker template error!错误。这是怎么回事啊？
详细的错误信息：
FreeMarker template error!
Method public java.util.List org.apache.struts2.components.Form.getValidators(java.lang.String) threw an exception when invoked on org.apache.struts2.components.Form@af7ec0
The problematic instruction:
----------
==> list tag.getValidators("${tagName}") as validator [on line 46, column 9 in template/xhtml/form-close-validate.ftl]
in include "/${parameters.templateDir}/xhtml/form-close-validate.ftl" [on line 25, column 1 in template/xhtml/form-close.ftl]

Java backtrace for programmers:

struts.xml里的代码片段：
<action name="registPro" class="com.kevin.action.RegistAction">
<!-- 为两个逻辑视图配置视图页面 -->
<result name="success">/WEB-INF/content/usercenter.jsp</result>
<result name="error">/WEB-INF/content/error.jsp</result>
<result name="input">/regist.jsp</result>
</action>
[解决办法]
已经解决。要把jsp页面通过action访问才能使用struts2的客户端校验
