这是页面js代码 Ext.onReady(function(){   var win=new Ext.Window({        html:""    }); 　　win.show();         })

下面是java中获取二进制的图片(补上）呵呵

public void getView(HttpServletRequest request,HttpServletResponse response,String id) throws IOException{byte[] datas=getViewdatas(id);//获得数据库中的保存的二进制图片InputStream inputstream=new ByteArrayInputStream(datas);OutputStream out=request.getOutputstream();int size=inputstream.read(datas,0,datas.length);if(size>0){　　out.write(datas,0,size);}inputstream.close();}
