I saw a unique error on the log:
Jul 15 10:37:27 pg-mx-srv pgpool: 2011-07-15 10:37:27 ERROR: pid 23970:
pool_init_pool_passwd: couldn't open /etc/pgpool2/pool_passwd. reason:
Permission denied
Which are the permissions of this file on your system?
Which is the log directory and its permissions?
Are you using JDBC for establish the connection with your Java application?
You should read the pgpool's resctrictions with JDBC because, this
driver uses PREPARED STATEMENT and it is not supported yet by the
middleware.
