Send a ResultSet object via RMI - won't work.

Question

Hi. I make a user interface to access MySQL database. The access to MySQL server is done from a remote location via RMI. The process to delete/update/create was succeed. The only problem is when I try to get(from the client computer) the ResultSet object, that come from invoking statementObject.executeQuery(myQuery) method, from the server Computer: it won't work. It said that the ResultSet object is not serialized(it is an interface). I need the ResultSet object for my client program since I will use it to set my AbstractTableModel class's object. Last goal is to put the AbstractTableModel object into the JTable constructor so I can see the result from a table.
Is anyone can help me? I can not return the ResultSet object to the client since it is not serialized.

I use the following solution using List. As List is Serlizable I can throw it across the network using RMI... it is also of course easy to access.......
For users objects you need to throw across the network just simply make them implement Serializable
In your ORM class accessing the DB:
public List getSQLResults{
Resultset SQLResults = statement.executeQuery(SQLQuery);
Vector results = new Vector();
while (SQLResults.next()){
// create class object here if needed...
results.add(SQLResults.getStrinf("COL_NAME");
return results;In your GUI class..
JTable theTable = new JTable();
DefaultTableModel theModel = new DefaultTableModel();
theModel.addColumn(SOME_COLUMN);
try{
List resultsData = ORMClass.getSQLResults();
Iterator iterator = List.Iterator();
while(iterator.hasNext()){
iterator.next();
theTableModel.addRow(SOME_OBJECT);
theTable.setModel(theModel);
catch(Exception ex){
// exception rasied...... do something!!!
}
