See DatabaseMetaData.getColumns

All the code you've showed us does is create a connection, open a result
set and print it.  You also note that this code works.  The
interesting code would be: the table definitions, the sql query, and
the actual printing code used.  Depending on how crystal reports works
these may not be easy things to get to, but you'll have to give us
something more to work with.
