Html output

I know when you use psql you can set the output of a query to html with a
"\H".  Is there a way in Java's JDBC to instruct postgres to return it's
results in this format?  If not, can I set postgres up to use html as it's
default response to queries?  If I can get this to work all I need to do
inside my program is send the result to the PrintWriter and display the
result.
