FCKeditor+Struts2 页面显示值栈内容

请问高手：     我的jsp页面想在FCKeditor调用值栈（value stack）中对象，应该如何调用呢我的值栈是这样的：Struts ValueStack DebugValue Stack Contents
Object Property Name Property Value  
                                                         merModel 特大 
                                                         status 0 
                                                         leaveFactoryDate 2012-03-14 00:00:00.0 
   com.eportal.ORM.Merchandise             
                                                         id 7 
                                                         picture null 
                                                         merDesc %3cp%3ecaiyi%26nbsp%3b%26nbs 
                                                         
如图中的merDesc对象值，我应该如何取得，并在页面初始化好直接显示呢？或者说我这个代码：代码一：/** HTML代码的UnEscape处理方法 */
 public static String  unescape(String src){
  StringBuffer tmp = new StringBuffer();
  tmp.ensureCapacity(src.length());
  int lastPos=0,pos=0;
  char ch;
  while(lastPos<src.length()){
   pos = src.indexOf("%",lastPos);
   if (pos == lastPos){
    if (src.charAt(pos+1)=='u'){
     ch = (char)Integer.parseInt(src.substring(pos+2,pos+6),16);
     tmp.append(ch);
     lastPos = pos+6;
    }else{
     ch = (char)Integer.parseInt(src.substring(pos+1,pos+3),16);
     tmp.append(ch);
     lastPos = pos+3;
    }
   }else{
    if (pos == -1){
     tmp.append(src.substring(lastPos));
     lastPos=src.length();
    }else{
     tmp.append(src.substring(lastPos,pos));
     lastPos=pos;
    }
   }
  }
  return tmp.toString();
 }代码二： <td colspan="3" height="500">
    <s:if test="merDesc!=null">
     merDesc not null
     <s:set name="contentvalue" value="@org.cy.msp.util.Tools@unescape(#request.merDesc)"/>
     ${contentvalue}
    </s:if>      
    <fck:editor id="merDesc"  basePath='<%=basepath + "/FCKeditor/"%>' height="500"
    imageBrowserURL='<%=basepath
       + "/FCKeditor/editor/filemanager/browser/default/browser.html?Type=Image&Connector=connectors/jsp/connector"%>'
    linkBrowserURL='<%=basepath
       + "/FCKeditor/editor/filemanager/browser/default/browser.html?Connector=connectors/jsp/connector"%>'
    flashBrowserURL='<%=basepath
       + "/FCKeditor/editor/filemanager/browser/default/browser.html?Type=Flash&Connector=connectors/jsp/connector"%>'
    imageUploadURL='<%=basepath
       + "/FCKeditor/editor/filemanager/upload/simpleuploader?Type=Image"%>'
    linkUploadURL='<%=basepath
       + "/FCKeditor/editor/filemanager/upload/simpleuploader?Type=File"%>'
    flashUploadURL='<%=basepath
       + "/FCKeditor/editor/filemanager/upload/simpleuploader?Type=Flash"%>'>
       ${contentvalue}
    </fck:editor>  
   </td> 为什么显示不出呢，代码一枚多大关系的，就是在<fck/>中显示出一个变量就好，求你们了，小弟先谢过了 - -
