我刚刚下载了Java ME Platform SDK 3.0并创建了我的frist Midlet(来自一些Oracle教程)。哪个在模拟器上工作正常。当我在诺基亚N97上部署它时,我可以运行它,但是一旦我按下“连接”并允许继续我得到IOException:-1

以下是代码:

package hello;
import java.io.*;
import javax.microedition.io.*;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

public class HelloMIDlet extends MIDlet implements CommandListener {

...

private void connect() {

HttpConnection hc = null;
InputStream in = null;
String url = getAppProperty("HitMIDlet.URL");

try {
  hc = (HttpConnection)Connector.open("http://www.google.ch"); 
  in = hc.openInputStream();
  byte[] raw = new byte[10];
  int length = in.read(raw);
  in.close();
  hc.close();

  // Show the response to the user.
  String s = new String(raw, 0, length);
  mMessageItem.setText(s);

}
catch (IOException ioe) {
  mMessageItem.setText( ioe.toString());
}
mDisplay.setCurrent(mMainForm);
}
}
