RE: JAVA400-L Digest, Vol 1, Issue 631

Hi,
Try this:

Before you can call your AS/400 pgm using CallableStatement you have to create 
stored procedure (using interactive sql ) command looks something like this:
CREATE PROCEDURE yourlib/yourpgm(IN p1 CHAR ( 10), IN p2 CHAR ( 15),
OUT p3 DEC (7, 2)) NOT DETERMINISTIC CONTAINS SQL EXTERNAL NAME   
yourlib/yourpgm PARAMETER STYLE GENERAL                             

After that you can:

   CallableStatement callStatement = connection.prepareCall("call 
yourlib.yourpgm (?, ?, ?) ");
   callStatement.setString(1, "  parm1   ");
   callStatement.setString(2, "  parm2   ");
   callStatement.registerOutParameter(3, java.sql.Types.DECIMAL);
   callStatement.execute();
   BigDecimal r = (BigDecimal)callStatement.getBigDecimal(3);

p3 is an out parm, so you can get something back from your AS/400.

Thank you all!

although I got another problem now:
When I execute 
        stmt.executeUpdate("CALL MYPGM('parm1')";
where 
        parm1="xxxxxxxxxx               "
it seems that the trailing spaces are left out at execution_time.... 

The CL/RPG program receives: "xxxxxxxxxx???????????????"
where ??...?? is 'rubbish' in stead of spaces.
Because the application checks if that part is blank
it goes wrong.

To be complete, the parameter is in fact a bit longer 
(first 15 chars are filled, next 350chars are a list
of 10-35char fields which sometimes contain data, sometimes not!
