Uhm, forget that, it was a silly idea from me to use both ends of a pipe
in the same thread, sorry. Lacking better ideas I suggest to use the other
suggested solution with a temporary file:
File tmpFile = File.createTempFile("exc", "tmp");
PrintWriter tmpOut = new PrintWriter(new FileWriter(tmpFile), false);
exception.printStackTrace(tmpOut);
tmpOut.close();
BufferedReader tmpIn = new BufferedReader(new FileReader(tmpFile));
StringBuffer stackTrace = new StringBuffer();
String line;
while((line = tmpIn.readLine()) != null)
{
stackTrace.append(line);
stackTrace.append("\n");
}
tmpIn.close();
tmpFile.delete();
// send email with the stackTrace...
This requires write access on the system's tmp dir, which you might
have to add to the secutity policy if your jsp/servlet-container is
using one. You can also choose a different directory, of course.
