pg_hba.conf issue

I wanna connect froma remote host to the Database via JDBC.
I modified the pg_hba.conf  to this :
<snip>
# In the absence of preceding "host" lines, these two lines will reject
# all connection attempts from 192.168.54.1 (since that entry will be
# matched first), but allow Kerberos V5-validated connections from anywhere
# else on the Internet. The zero mask means that no bits of the host IP
# address are considered, so it matches any host:
#
  host       all        192.168.1.0    255.255.255.255    trust sameuser
</snip>

I got the following trace :
<snip>
94 [main] WARN org.test.JDBCPostgres.TestJDBCPostgres  - Message : Something

sual has occured to cause the driver to fail. Please report this exception:

My internal network is of course a 192.168.1.x
DB is
<snip>
[postgres@stackanov data]$  ifconfig

While client is : 192.168.1.101

Could some one hint me on what I should do ?
