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 at org.postgresql.Connection.openConnection(Unknown Source) at org.postgresql.Driver.connect(Unknown Source) at java.sql.DriverManager.getConnection(DriverManager.java:512) at java.sql.DriverManager.getConnection(DriverManager.java:171) at pl.test.PostgresqlDatabase.getNewConnection(Unknown Source) at pl.sql.RelationalDatabase.getConnection(RelationalDatabase.java:278) at pl.PersistenceManager.getConnection(PersistenceManager.java:927) at pl.PersistenceManager.saveObject(PersistenceManager.java:289) at pl.PersistentObject.save(PersistentObject.java:133) at pl.test.Test.performTest(Unknown Source) at pl.test.Test.main(Unknown Source) End of Stack Trace
