Accessing a nested JPanel

Question

The format:
JFrame that contains 2 JPanels that I want to switch depending on user input.
I've tried from with the JFrame code:
JPanel jpanel1 = new JPanel();
The constructor in JPanel1 creates an instance of jPanel2 & jPanel3.
jPanel1.jPanel2.setVisible(true);
jPanel1.jPanel3.setVisible(false);
This doesn't work - any ideas on how to accomplish the task?
Thanks,
Michael

Answer 1

What jdbc driver and database version are you on? What happens if you do not cast to Status? Does it return a STRUCT? What is the stack trace?
The following seems to work:
create or replace type status_typ is object(
attribute1 varchar2(50),
attribute2 varchar2(50),
attribute3 varchar2(50)
create or replace type status_tab is table of status_typ
create or replace procedure get_status(
  s out status_tab
) is
begin
s := status_tab(status_typ('a','b','c'));
end;
show errors
  // Status.java
  public class Status implements SQLData {
    protected String
      attribute1, attribute2, attribute3, sql_type;
    public String getSQLTypeName() {
      return sql_type;
    public void readSQL(SQLInput stream, String typeName) throws SQLException {
      sql_type = typeName;
      attribute1 = stream.readString();
      attribute2 = stream.readString();
      attribute3 = stream.readString();
    public void writeSQL(SQLOutput stream) {
    OracleCallableStatement cs = (OracleCallableStatement)conn.prepareCall(
    "{call get_status(?)}"
    cs.registerOutParameter(1, OracleTypes.ARRAY, "STATUS_TAB");
    cs.execute();
    Map map = conn.getTypeMap();
    map.put("STATUS_TYP",Class.forName("Status"));
    int i = 0;
    ResultSet rs = cs.getArray(1).getResultSet();
    while(rs.next()) {
      Status s = (Status)rs.getObject(2);
      System.out.println("Row " + i++ + " " + rs.getObject(2) + " " + s.attribute1 + "," + s.attribute2 + "," + s.attribute3);
Row 0 Status@b01d43 a,b,c
