分页：
  Query q = this.session.createQuery("FROM Teacher as tch order by tch.tid");

%{#request.info} 等同于 request.getAttribute("info");


<s:text name="atic.bis.divert.deleting"/>
<s:url value="/vsm/atic/resource/libs/bis/divert/tactics/divertTacticsList.js"/>


struts2的配置文件继承json-default时，需要这两个包：
jsonplugin-0.30.jar
json-lib-2.3-jdk15.jar
<package name="sgmsjson" extends="json-default" namespace="/sig/sgms/json">
<action name="testCombobox"
class="com.hs.sig.ui.sgms.webapp.action.ShowPageAction"
method="testCombobox">
<result name="success" type="json"></result>
</action>
</package>
