Enterprise Data Acces Block with Oracle and Stored Procedures   

Hi all,

Does anybody have an example or know where I can find one that shows the use 
of .NET Enterprise Data Acces Block with Oracle and Stored Procedures.  I am 
trying to  fill a dataset, but I cannot do it.

The SP is:

PROCEDURE GetCustomerList(cursor OUT endaab.refcur) IS
  BEGIN
    OPEN cursor FOR
    SELECT *
    FROM
           "CUSTOMERS";
  END GetCustomerList;

And the function call is:
                        //Create database instance
                        Database db = 
DatabaseFactory.CreateDatabase(instanceName);
                        //Initialize the stored procedure
                        DBCommandWrapper dbCommandWrapper = 
db.GetStoredProcCommandWrapper("endaab.GetCustomerList");
                        //Generate DataSet object
                        DataSet ds = null;
                        ds = db.ExecuteDataSet(dbCommandWrapper);
                        //Fill datagrid
                        if (ds.Tables[0].Rows.Count > 0)
                        {
                              //Supposing we have a datagrid whose id is 
DataGrid1
                              DataGrid1.DataSource = 
ds.Tables[0].DefaultView;
                              DataGrid1.DataBind();
                        }
                        else
                              Response.Write("No rows were selected");

But....the following error is arising:

System.Data.OracleClient.OracleException: ORA-06550: line 1, column 7: 
PLS-00306: wrong number or types of arguments in call to 'GETCUSTOMERLIST' 
ORA-06550: line 1, column 7: PL/SQL: Statement ignored at 
System.Data.OracleClient.OracleConnection.CheckError(OciErrorHandle 
errorHandle, Int32 rc) at System.Data.OracleClient

Could you please help me with this issue?

Thank you very much in advance,

Marco
