Problem with get ResultSet from rmi jdbc method. Help.

Question

Hi,
I am writing a rmi jdbc server. I got all the rmi methods working, but I am trying to get the data from the ResultSet. After the query, I set the fields in the serialiable class and return it back to the client. However, I noticed that it does called init(), but not the setField calls. When it calls the first setField in the serialiable class, the method is never called. Can anyone give some guidance.
Thanks,
Rage
This method is called from the client to set all the data in the Serialiable class and return it to the client.
public Collection fetchResultSet() throws RemoteException
System.out.println("Entering fetchResultSet");
Collection resultSetColl = new ArrayList();
QueryResultSet recordset;
try
int rowCount = 0;
ResultSetMetaData rsmd = rs.getMetaData(); // Get data dictionary information
int columnCount = rsmd.getColumnCount();
System.out.println("got column count");
System.out.println("" + rowCount + " rows, " +
columnCount + " columns");
if (rs == null) System.out.println("rs is null");
if (rs.next())
System.out.println("Parsing RS");
recordset = new QueryResultSet();
for (int i = 1; i <= columnCount; i++)
System.out.println("set Fields = "+ rs.getString(i) );
//recordset.setField(i,rs.getString(i));
String strValue = rs.getString(i);
recordset.setField(i,strValue);
System.out.println("Added recordset" );
resultSetColl.add(recordset);
catch (Exception e)
System.out.println(e.getMessage());
closeResultSet();
return resultSetColl;
Here is my Serializable Class
import java.io.*;
import java.sql.*;

public String getField(int nField)
System.out.println("QueryResultSet getField()");
System.out.println("getField 1 = " + Field1);

return null;
public void setField(int nField, String strField)
System.out.println("QueryResultSet setField()");
System.out.println("field #" String.valueOf(nField) " = " + strField);
if (nField == 1)

You need to give us some information more. Like what rdbms are you using, what driver and how are you trying to access the resultset from java.
I do not know what are you using. One thing I can tell you for sure is that the execute method returns a boolean. If you need a resultset you should run executeQuery.
