Your English is fine, but you haven't actually described what it does
wrong. A few things though:
o Your URL looks wrong. I think it should be "jdbc:postgresql://BDPrueba".
o I think it fairly unlikely, although possible, that no username and
password are required, but I guess you know what's correct for your
instance.
o Make sure you start the postmaster with the -i switch so that it listens
on tcp sockets, not just UDP. I think this is necessary for JDBC; it is
certainly necessary for ODBC, and it took me four or five hours to work
out that this was my problem.
Send us some more details of what actually goes wrong, like 'it throws
exception x' or 'this statement just sits there doing nothing,' rather
than, 'I'm having problems using JDBC driver.' Code snippet is good,
though - wish more people would do that!
