j2me连接网络的问题

[ybbxk119]

我写了一个死循环，每3秒重复访问一个sevlet，这个sevlet返回一个图片地址，问题是用真机访问这个servlet到一定次数,就提示连接失败的异常，用模拟器就没问题，请教……

HttpConnection con = (HttpConnection) Connector.open(url);
con.setRequestMethod(HttpConnection.POST);
con.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
con.setRequestProperty("User-Agent","Openwave");
con.setRequestProperty("Content-Language","en-US");
con.setRequestProperty("Accept","application/octet-stream");
con.setRequestProperty("Connection","Keep-Alive ");

int s = con.getResponseCode();
DataInputStream dis = new DataInputStream(con.openInputStream());
if(s==HttpConnection.HTTP_OK ){
String path = dis.readUTF();
System.out.println("图片地址为："+path);
loadImage( path );//读取图片
}

网络连接完毕后注意及时close DataInputStream 和HttpConnection

模拟器的网络要比真机快的多，你把时间调长点
