Hi,
I'm trying to read a file via http. (http://www-lehre.inf.uos.de/
~mmenning/balingen.ts). I wrote a Connector Class:
package gip.android.ogl;
import java.io.IOException;
import java.io.InputStream;
import java.net.URL;
import android.util.Log;
public class DataConnectorTS {
private final String DEBUG_TAG = "DataConnectorTS";
public DataConnectorTS() {}
public void requestTS(String address) {
try {
URL url = new URL(address);
Log.d(DEBUG_TAG, "url: " + url);
Log.d(DEBUG_TAG,"host: "+url.getHost());
readData(url.openStream());
} catch (IOException e) {
Log.e(DEBUG_TAG, "JML request IOError", e);
}
}
private void readData(InputStream in){
}
}
But by trying to connect in the ActivityClass
DataConnectorTS dcts= new DataConnectorTS();
dcts.requestTS("http://www-lehre.inf.uos.de/~mmenning/
balingen.jml");
I will only get the following ExceptionTrace:
01-27 17:00:18.605: ERROR/DataConnectorTS(182): JML request IOError

I already added the uses-permission Internet Tag to the manifest.xml
(above the application tag).
I can create the URL Instance but not call openStream().
Any Idea what the problem could be?
Thanks for any help
Mathias
