getMethodName()

I have the following code in a subroutine of a class which is intended
to give the user (me) some information as to the nature of the error.
In addition I want to include in the MessageDialog the name of the
method that invoked the error. How do I get hold of the method name
when running?
See below especially ??????.getMethodName. Am I close?

try {

} catch (ParserConfigurationException pce) {

            JOptionPane.showMessageDialog(
                    null,
                    "explicit error message",
                    ??????.getMethodName() + " ParserConfigurationException - Error!",
                    JOptionPane.ERROR_MESSAGE);

}

Read the documentation for java.lang.Throwable. This is what you need:

pce.getStackTrace()[0].getMethodName();

Start with Throwable.getStackTrace(). The rest is apparent from the API
documentation of that method. I am to lazy to look it up at the moment.

Interrogating the getStackTrace only got the failed method in the java
libraries. What I wanted was the failed method in the code that I'd
written. However, the above suggestion did point me in the right
direction. So what I did to get the method was to loop through each of
elements of the stack trace until I found a match on my class. I Then
found
fillInStackTrace that put my Method to the top of the stack so then I
could use the above
pce.getStackTrace()[0].getMethodName();

Thanks
