   Your database url is wrong. A postgres database needs the following URL:
   jdbc:postgresql://theComputerName/thePostgresDatabaseName
   if you omit something, you get your NullPointerException

   I am having the same problem. I tried the new URL. The problem still
   continues. Is there a chance I still need to do  a make to create the
   posgresql.jar file. I have installed the postgresql rpm's for
   posdtgres6.5/. Any Ideas on how to do the make in postgresql 6.5
