SQLException 9999:9999 getConnection - stack trace & complete program

["Steve Swett" <swett@xxxxxxxxxxxxxx>]

This short java application uses Toolbox for Java to use JDBC and SQL to
read in a result set and then load the first result set record into a
combobox.  Very easy -- just to test AS/400 db connectivity.  Surprisingly,
it won't work.  Here's the stack trace and complete source code.  Any ideas?

I'm using: OS/400 V4R4, the jt400.zip file that comes with Client Access
V4R4M0 service level SF60796, and JBuilder4 IDE.  I'm using the JRE that is
supplied with JBuilder4 (from the c:\jbuilder4\jdk1.3\bin folder).


Steve's note: * SQL Exception occurred error is 9999:9999 string is
java.sql.SQLException: 9999:9999 *
