MSSQL Stored Procedure has duplicate OUT parameter

Question

Hi All;
I am using the WLS MSSQL jdbc driver (mssqlserver4v70rel510sp8) for wls
5.1 sp 12. The following code generates a duplicate OUT parameter.
Parameters 4 and 5 are duplicated. I went over the stored procedure in
ISQL, and the problem is not occurring there. Has anyone seen this sort of
problem? I noticed this problem does not occur when I have the "?=" in
front.
stmt = con.prepareCall("{ ?= call webactivate..ValidatePromoCode(?, ?,
stmt.registerOutParameter(1, java.sql.Types.INTEGER);
stmt.setString(2, marketingCode);
stmt.setString(3, activationData.getRawServiceNumber());
stmt.registerOutParameter(4, java.sql.Types.VARCHAR);
stmt.registerOutParameter(5, java.sql.Types.INTEGER);
stmt.registerOutParameter(6, java.sql.Types.INTEGER);
stmt.execute();
Log.putDebug("#1="+stmt.getString(1));
Log.putDebug("#4="+stmt.getString(4));
Log.putDebug("#5="+stmt.getString(5));
Log.putDebug("#6="+stmt.getString(6));

Thanks Joseph. I was hoping you would get back to me on this. You are the
king of this newsgroup. Here's what I got, which indicates some type of
problem on my end:
Update count = 1
Update count = 1
Update count = 1
Update count = 1
Update count = 1
Output status: 4
Output param 1: 4
Output param 2: marketingCode activationData.getRawServiceNumber()
Output param 3: 2

let me know the output. it works with the latest driver I have. I get:
C:\joe\70bugs>java foo
Update count = 1
Output status: 4
Output param 1: marketingCode activationData.getRawServiceNumber()
Output param 2: 2
Output param 3: 3
The code:
import java.sql.*;
import java.util.*;
class foo {
public static void main(String[] args) throws Exception
Properties props = new Properties();
props.put("user", "sa");
props.put("password", "");
props.put("server", "natoma");
try {
Driver myDriver = (Driver)
Class.forName("weblogic.jdbc.mssqlserver4.Driver").newInstance();
Connection con = myDriver.connect("jdbc:weblogic:mssqlserver4",props);

System.out.println("Get first resultset col by id:" +rs.getString(1));
rs.close();
} // Otherwise, there will be an update count
else {
System.out.println("Update count = " + updateCount);
stmt.getMoreResults();
// Best to retrieve status and output parameters
