Question

hello,
i'm using ms access database and i'm trying to retreive data from it,
i'm using sql queries and it work well, but my last quesry won't execute and i got an error message sql exception error "invalid handle"
here's my code
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String filename = "C:/base.mdb";
String database = "jdbc:odbcriver={Microsoft Access Driver (*.mdb)};DBQ=";
database += filename.trim() + ";DriverID=22;READONLY=true}";
Connection con = DriverManager.getConnection(database, "", "");
Statement s = con.createStatement();
s.execute("select * from domaine");
ResultSet rs0 = s.getResultSet();
if (rs0 != null) // if rs == null, then there is no ResultSet to view
while ( rs0.next() ){
jComboDomaine.addItem(rs0.getString(2));}
s.execute("select * from population");
ResultSet rs1 = s.getResultSet();
if (rs1 != null) // if rs == null, then there is no ResultSet to view
while ( rs1.next() )
{jComboPopulation.addItem(rs1.getString(2));}
s.execute("select * from Spopulation");
ResultSet rs2 = s.getResultSet();
if (rs2 != null) // if rs == null, then there is no ResultSet to view
while ( rs2.next() )
{jComboSpopulation.addItem(rs2.getString(3));}
s.execute("select id_cas,TitreCas from CasN2");
ResultSet rs3 = s.getResultSet();
if (rs3 != null) // if rs == null, then there is no ResultSet to viewew
while ( rs3.next() )
{ cache.add (rs3.getString(2));
cache_Id.add (rs3.getString(1));
jListCas = new JList(cache);
new View1(jComboPopulation,jComboSpopulation,jComboDomaine,jListCas,jListSolution,s,cache,cache_Id);
main
public Vector action(int c){
System.out.println("OK");
Vector temp = new Vector();
try{
s.execute("select DescriptionS from CasN2 where Id_cas= ' 120 '");
ResultSet rs4 = s.getResultSet();
temp.addElement(rs4.getString(1));
catch (Exception e) {
System.out.println("Error: " + e);
return temp;
thank you.
