在jsp解密类型中调用session.get属性（）方法时无法解析会话

Question

在 jsp 中调用 session.getAttribute（） 方法后，我收到错误为“会话无法解析”。请建议解决它。提前谢谢。代码如下-

<%!
String getApplicantDetailsRow(ApplicantAdminViewTO viewTO, ResourceBundle labelResourceBundle, boolean actionNotepadModule,boolean directLettingModuleFlag,boolean canPrepareApplicantMatchList,boolean canViewOtherSubPortalApplicants,boolean canViewOtherSubPortalBids,boolean canViewAndEditOtherSubPortalApplicants,String strSaccCode){

        PartnerTO partnerTO;
       <% CBLContext cblContext = (CBLContext) session.getAttribute(CBLConstants.CBLContext) %>;
        partnerTO = cblContext.getCBLPartner();
        long pid=partnerTO.getPartnerId();

        strBuild.append("<td class=\"caption\">");

错误是-

jsp文件中的第139行发生错误：

“会话无法解决”

行：139-<代码>

“会话无法解决”

JSP中的会话对象是隐式对象。您只能在脚本小程序中使用它，它在声明中不可用（在块中）
