Stream closed
Hi,
I cannot find the reason for
java.io.IOException: Stream closed
as "System.out.println (...)" prints these lines, but FileWriter breaks after the 2nd line (when I look inti the ouput file).
Error message in detail:

Sourcecode:
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
/* @author scm */
publicclass TextOut{
BufferedWriter bWriter;
public TextOut(String driveNam, String dirNam, String fNam)throws IOException{
if (driveNam.equals("")) driveNam ="c";
if (driveNam.trim().endsWith(":") ) driveNam = driveNam.trim().replaceFirst(":","");
if (dirNam.equals("")) dirNam ="a_ablagefluechtig";
if (fNam.equals("")) fNam ="InOut.txt";
bWriter =new BufferedWriter (new FileWriter (driveNam+":\\"+dirNam+"\\"+fNam));
}
publicvoid out01 (String txt){
System.out.println (txt);
try{
bWriter.write(txt);
}catch (IOException e){
e.printStackTrace();
}
try{
//bWriter.write("\r\n");
bWriter.newLine();
}catch (IOException e1){
e1.printStackTrace();
}
}
publicvoid fClose()throws IOException{
bWriter.close();
}
}
It happens the same way without BufferedWriter
The calling code line is
txout.out01 ("Rekursions-Ebene: "+tmpInt+", child no. "+i+", child name: "+children.elementAt(i).toString()+", node: "+node.toString());
-> node is of type DefaultMutableTreeNode
-> children.elementAt(i).toString() is of following Object type
Who's got an idea?
Thanks
