dwr获取session和list转化为字符串

DWR获取session、request
import uk.ltd.getahead.dwr.WebContext;
import uk.ltd.getahead.dwr.WebContextFactory;
WebContext ctx = WebContextFactory.get();
                        //DWR Web上下文工厂  
HttpServletRequest request = ctx.getHttpServletRequest();  //通过WebContext获取Request  
HttpSession session = ctx.getSession(); 
                              //通过WebContext获取Session
 普通的获取session

HttpSession session = ServletActionContext.getRequest().getSession();
HttpServletRequest request = ServletActionContext.getRequest();

//在struts2中将List转换为字符串
   private String getListStr(List<Str> str)
       {
                return str.toString().subString(1,str.toString().length-1);
       }
