Postgresql 7.4.1 and jdbc errors

Hi,

I am using Postgresql 7.4.1 and pg74.214.jdbc3.jar.
Postgresql is started under port 52008.
I am using a java program to connect to the database.
I am using java1.4.2_07_b05 on solaris.

I am getting the following error.

org.postgresql.util.PSQLException: The connection attempt failed
because Exception: java.net.NoRouteToHostException: Cannot assign
requested address
Stack Trace:

Please help me with this.
