Hi!

I get an obscure SQLException message when I try to call
stored procedure in MS SQL Server 7.0. The message is
as follows:

java.sql.SQLException: Protocol confusionFound a

The Java method that handles calls to stored procedure is 
following:

 public static int MyCallable1(String sp,Object[] array, String dbname) 
throws Exception {

                connMgr = DBConnectionManager.getInstance();
                Connection conn = connMgr.getConnection(dbname);

                if ( conn == null) {
                       Logging.log( new Exception(), "DB:int MyCallable1 -- 
conn==null");
                       throw new Exception();
                }
                if (sp == null) {
                        Logging.log( new Exception(), "DB:int MyCallable1 
-- sp==null");
                        throw new IllegalArgumentException("stored 
procedure not specified");
                }
                 
                int iReturned = -1;
               
                CallableStatement cst = conn.prepareCall("{ "+sp+" }");

                if ( array != null ) {
                    String className = null;
                    for (int i=0; i< array.length; i++) {
                         className = array[i].getClass().getName();
                         if ( className.equals("java.lang.String") ) {
                                cst.setString(i+1, (String) array[i]);
                         } else if ( className.equals("java.lang.Integer") 
) {
                                cst.setInt(i+1, ((Integer) 
array[i]).intValue());
                         }
                    }
                }
                try {
                        iReturned = cst.executeUpdate();
                } catch (SQLException e) {
                        Logging.log(e, "DB: int MyCallable1" );
                }
                 
                connMgr.freeConnection(dbname, conn);

                return iReturned;}

Probably it's an idiotic mistake, but I can't figure it out
what's the catch with this :-) So if anybody got any 
idea please do not hesitate to come up with your opininion.

Tnx in advance.
