how can I make a conection to informix

first create an entry in sqlhosts or modify. $INFORMIXDIR/etc/sqlhosts os whereever INFORMIXSQLHOSTS points to myserver sesoctcp <yourhostname> <someserverice or 1533> #----------^^^^^^^^ or setlitcp check rel notes. if you use someserverice add someserverice to /etc/services with portno 1533. then as root with env var INFORMIXDIR set correctly and INFORMIXSERVER=myserver $INFORMIXDIR/lib/sqlexecd $INFORMIXSERVER then check if you can connect with dbaccess. when this is ok try your java stuff Superboer.
