我刚刚下载了 Java ME Platform SDK 3.0 并创建了我的第一个 Midlet（来自一些 Oracle 教程）。在模拟器上运行良好。当我在诺基亚 N97 上部署它时，我可以运行它，但只要我按下“连接”并允许继续，我就会得到一个 IOException：-1
这是代码：
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);
}
}
