IPv6 patch doesn't work fine

Hi all.

I have a Java application that it connects to the PostgreSQL database with IPv6 patch installed.

I obtain the following error:

   Something unusual has occured to cause the driver to fail.
   Please report this exception: java.lang.NullPointerException
      at org.postgresql.Driver.connect(Driver.java:125)
      at java.sql.DriverManager.getConnection(DriverManager.java:512)
      at java.sql.DriverManager.getConnection(DriverManager.java:171)
      at piscis.pki.ca.database.DBManager.connect(DBManager.java:78)

In my class DBManager I have the following connection method:

   class.ForName("org.postgresql.Driver");
   Connection connect = DriverManager.getConnection(<dir. IPv6>,<user name>,<password>);

Which is my error?? Need I a special postgresql.jar??


Regards...
