Are you sure about the IP 192.168.1.1? Normally that would be the default gateway of your subnet. – Ralf
Look further down the exception tree for the real error. You're probably looking for a JDBC driver error. At a guess, it's failing to connect, probably because that IP isn't running PostgreSQL, is firewalled off, or has Pg only listening on the loopback interface. (In future please format exceptions with the "{}" button, so they're readable, too). – Craig Ringer
Also check your pg_hba.conf – Konstantin V. Salikhov
Ya ip is correct i checked it by using ipconfig in server & What to do in pg_hba.conf – Sumeet
@Sumeet I'm willing to bet it's still not correct. Post the output of ipconfig. – chrylis -cautiouslyoptimistic-

First you need to gain some basic knowledge of networking. Test if the database server if accessible and no firewall is blocking it (eg: using telnet).

Then if you look down your exception trace, it complained about the lack of hibernate.dialect. Typically this is set on META-INF/persistence.xml like following:

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
             version="2.0">
   <persistence-unit name="sample">
      ..
      <properties>
         <property name="hibernate.dialect" value= "org.hibernate.dialect.PostgreSQLDialect"/>
         ...
      </properties>
   </persistence-unit>
</persistence>
