//Ofer,
//Take a look at #1. Test this to see if we have a problem in dispose. If we do, add a test for this to make sure we catch it in next rounds.

//Subject: 2 problems from Synergy
//Please check those 2 problems reported by Synergy and tell me what do you think.
//1) The following code works in dotnet but doesn//t work in j2ee.
//// Oracle Drivers
//OleDbConnection Connect;
//OleDbDataReader DbReader;
//OleDbCommand DbCommand;
//IDataReader DR;
//string sSQL;
//int iField;
//bool bFound;
//try
//{
//Connect = new OleDbConnection("Provider=\"MSDAORA.1\";User
//ID=COM;Password=SQL;Data Source=LLO1;HostName=WS10359;Port=1521");
//Connect.Open();
//sSQL = "SELECT * FROM PRODUCT WHERE PRO_SKU = //SKU_208//";
//DbCommand = new OleDbCommand(sSQL, Connect);
//DbReader = DbCommand.ExecuteReader(CommandBehavior.SingleRow);
//DR = DbReader;
//DbCommand.Dispose(); // comment out
////DbCommand = null;
//bFound = DbReader.HasRows;
//DR.Read();
//// Get Column Ordinal
//iField = DR.GetOrdinal("PRO_DESCRIPTION");
//string sDesc = DR.GetString(iField);
//}
//catch(Exception e)
//{
//this.WriteErrorLog(e.Message);
//}
//i have identified the problem as being "DbCommand.Dispose()". If you comment this line out or make it
//"DbCommand = null", then its okay. So this instruction doesnt work the same in both in .net and j2ee.
