asked on
get method and class names
I have created a class to format error messages. I
would like to use it instead of things like
System.out.println(). I
would like this object to tell me who called it.
Is the a way to discover the class and method name of
the caller? printStackTrace() would be nice but it looks
like I need to catch().

Works! But let me follow up 1st. I get a deprecation
notice. Is this something I can correct or should I close
my eyes?

ream) has been deprecated.

Note: CtlLogger.java uses a deprecated API. Please consult the documentation
for a better alternative.

ps Use PrintWriter instead of PrintStream in 1.1

Spoke too soon. It compiles with printwriter but
no stack info.
no stack info.
Throwable e=new Throwable();
ByteArrayOutputStream bo;
e.printStackTrace(new PrintStream(bo=new ByteArrayOutputStream()));
String stktrc=bo.toString();
Now the String stktrc contains a stacktrace, and you can slice it and dice it any way you like; print the first line, or the second line, or the whole thing!
