Hi,
 
i have trouble using PostgreSQL7.1.3 via jdbc on my Windows XP System
(using the actual cygwin distribution and j2sdk1.4.0).
 
The Database sends following error message after connection:
 PacketReceiveFragment: read() failed: Connection reset by peer
 
The Java Program prints following stack trace:
 ---Single simple object test and transaction test
 pl.PlException: org.postgresql.util.PSQLException:
 Something unusual has occured to cause the driver to fail.
 Please report this exception: Exception: java.lang.NullPointerException
 Stack Trace:
 java.lang.NullPointerException
