Help With the JDBC driver

Hello I am on a SCO UNIXWARE 7.1.1 box using java version 1.1.7b with the
jdk being 1.2. I am trying to connect to an Postgres database which is in
my network. I am using the pg73jdbc1.jar and have also tried to use the
pg73jdbc2.jar to connect. The following line of code works.
<<...OLE_Obj...>> Then I try to run the next line and I get an error.
<<...OLE_Obj...>>
The error is as follows
Something unusual has occured to cause the driver to fail. Please report
this exception: Exception: java.lang.IllegalArgumentException:
