AS400 and Java CallableStatement woes

[StokesP@xxxxxxxxxxxxxxxx]

Hi,
I am having problems calling a RPG ILE program on AS400 from a Java class
using Java's CallableStatement (JTOpen). I have two versions of the RPG
program, one takes an input param and gives output in the second param, or
one that takes the input param and gives output in the same param space.
The only way I can seem to prove it actually calls the program is when I
hard code my policy number into the prepareCall statement and make sure
there are no "?"'s.
Though this is useless to me because I need to get the returned string from
the program.
If I do anything other than hard code my policy into prepareCall then I
always get a SQLException on the prepareCall, it generally complains about
not finding the program.
This is just a quick test class, once proven, it's going into a struts
webapp so I want to use commons dbcp and not the AS400 classes directly
like
AS400 as400 = new AS400("10.2.0.3");.
Any comments would be appreciated !
Thanks,
Pete.

public static void main(String[] args){
     CallableStatement csmt = null;
     ResultSet rs = null;
     Connection con = null;

     try{
       Class.forName("com.ibm.as400.access.AS400JDBCDriver");
     }catch(Exception e){
       System.out.println(e.toString());
     }
     try{
        con = DriverManager.getConnection("jdbc:as400://10.2.0.3; translate
         binary=true;date format=iso; errors=full;
         libraries=LIBA,LIBB,LIBC,LIBD");
         csmt = con.prepareCall("call LIBB.Y00405(?,?)");
         smt.setString(1, "'ABC/REF/POLICY'");
         csmt.registerOutParameter(2, Types.VARCHAR);
          csmt.execute();
System.out.println("++++RESULT: " + csmt.getString(2));
