Re: getGeneratedKeys( ) Problem in JSF

I am trying to retrieve the primary key from a newly inserted row in
an Oracle Database from a JSF application. However, when I execute
this line:

Integer x = rs1.getInt("PurchaseID");

in the code below I get an SQLException "Unsupported Feature". I'm
using Oracle Database 10g and ojdbc14.jar.
Could be a jdbc driver problem but I'm not sure. Could someone help
me out here??
...
Statement stmt2 = conn.createStatement();

SQLStatement1 = new StringBuffer("INSERT INTO Purchase (PurchaseID,
CarModelID) VALUES (");
SQLStatement1.append("PurchaseID_Seq.nextval, ");
SQLStatement1.append(ModID + ")");

stmt2.executeUpdate(SQLStatement1.toString(),
Statement.RETURN_GENERATED_KEYS);

ResultSet rs1 = stmt2.getGeneratedKeys();

if (rs1.next())
{
      Integer x = rs1.getInt("PurchaseID");

}
