ex.printStackTrace(outputStream);

where ex is your exception object, and outputStream is a FileOutputStream previously opened.

Hi,
I have written the following code in catch block

catch (Exception e)
{
OutputStream bos = new FileOutputStream("Log");
e.printStackTrace(bos);
}


I am getting the following error, when I execute the above code:

dbUpload2.java:106: cannot find symbol
symbol : method printStackTrace(java.iutputStream)
location: class java.lang.Exception
e.printStackTrace(bos);

Try this :


catch (Exception e)
{
PrintWriter pw = new PrintWriter(new FileOutputStream("Log"));
e.printStackTrace(pw);
}
