Search Action Class :
public String search() {
HttpServletRequest request = ServletActionContext.getRequest();
HttpSession session = request.getSession();
session.setAttribute("sort", "1");
dosearch(false, true);
populateList(); // this method always populate formatList
return "success";
}
스트럿츠 설정 :
<action name="search" class="com.view.SearchAction"method="search">
<result name="input" type="tiles">search</result>
<result name="success" type="tiles">search</result>
<result name="error" type="tiles">search</result>
</action>
