Subject: How to fill what printStackTrace() output into a String?


Hi, all

I want to get the exception stack trace and I 'd like to use a
String to contain the info, How can I do?

I am thinking about this: (ex is an instance of Exception )

      PrintStream trace = new PrintStream();
      ex.printStackTrace(trace);
      String str = doSomeThing (trace);

Then how to write the function doSomeThing() ?

Is there any elegance solution?

TIA
Chris
