StackTraceString

Posted by Matt Gerrans on December 03, 2001 at 4:00 PM

Here's how I did it. Maybe you can try it out and see if it works for you.

static String getStackTrace( Throwable t )
{
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    PrintWriter pw =  new PrintWriter(bytes);
    t.printStackTrace( pw );
    pw.close();
    return bytes.toString();        
}
