Help needed using JDBC with MS SQL Server 2000

I've probably used stored procedures a 1,000 times before with other JDBC drivers and had no problems.  Now I'm building an application that interfaces with SQL Server 2000 and need to use some stored procedures that return not only a ResultSet, but a out parameter as well.  My Java method starts off like this:

    public synchronized ArrayList getValuationEOD(String accountName, Date date) throws SQLException
    {
        valSummaryStmt.clearParameters();
        valSummaryStmt.setString(2, accountName);

        String dateYMD = Utils.formatDateYMD(date);
        valSummaryStmt.setString(3, dateYMD);

        valSummaryStmt.registerOutParameter(1, BaseData.INTEGER);
        ResultSet rs = valSummaryStmt.executeQuery();
        int rowCount = rs.getInt(1);

        // Create ArrayList of ValuationSummary objects (with ValuationContractDetail object)
        ArrayList list = new ArrayList();

        // return with an empty ArrayList if there were no records returned; DO NOT PROCESS
        // FURTHER!!!
        if (rowCount == 0) return list;

        ValuationSummary vs = null;
        while (rs.next()) {
           // ... do something with the data
        }
        rs.close();

        return list;
     }

where BaseData is in the package com.microsoft.jdbc.base
and the property valSummaryStr is defined as:

    private final String valSummaryStr = "{?=call dbo.LOTS_GetValuationEOD(?, ?)}";

NOTE: I did a prepareCall(valSummaryStr) before I call the method above.

Upon executing the query, I get the following error:

java.sql.SQLException: [Microsoft][SQLServer JDBC Driver]Invalid parameter bindi
ng(s).

        at weblogic.kernel.ExecuteThread.run(ExecuteThread.java:129)

Where are the JDBC Types defined for the MS drivers? Are there any other problems with the way I'm doing this?  

All help will be greatly appreciated.

I'm now trying to declare the call String as
    private final String valSummaryStr = "{?=call dbo.LOTS_GetValuationEOD(?, ?, ?)}";

where the third parameter is the parameter that I want to retrieve as my out parameter (the third parameter to the stored procedure is declared as an OUTPUT parameter).

Thanks again for any help.

Try this:

private final String valSummaryStr("{begin call dbo.LOTS_GetValuationEOD(?,?,?); END;}");

I had the same problem with u earlier...
