Getting ClassCastException in client
Am getting an ClassCastException when I try to parse Object to File and I really dont know why? This is the find method in BMP bean:
public Enumeration ejbFindAll()
{
Vector l = new Vector();
Connection con = null;
ResultSet rs = null;
try
{
con = getConnection();
Statement s = con.createStatement();
rs = s.executeQuery("SELECT * FROM file");
while (rs.next())
{
File f = new File(rs.getInt("id"),
rs.getString("title"),
rs.getInt("length"),
rs.getDate("startDate"),
rs.getDate("endDate"),
rs.getString("description"),
rs.getDate("created"),
rs.getString("userName"),
rs.getInt("typeId"));
l.add(f);
}
}
catch (SQLException e)
{
e.printStackTrace();
}
finally
{
try
{
if (rs != null)
{
rs.close();
}
if (con != null)
{
con.close();
}
}
catch (SQLException e)
{
}
}
return l.elements();
}This is the method where I want to retrieve the data from Enumeration:
public void getDataBMP()
{
setRowCount(0);
Iterator it=null;
Enumeration col=null;
try
{
Context ctx = new InitialContext();
Object temp = ctx.lookup("ejb/entity/BMP/FileBMP");
FileBMPRemoteHome fileRemoteHome = (FileBMPRemoteHome) PortableRemoteObject.narrow(temp,FileBMPRemoteHome.class);
col = fileRemoteHome.findAll();
}
catch (ClassCastException e)
{
e.printStackTrace();
}
catch (NamingException e)
{
e.printStackTrace();
}
catch (FinderException e)
{
e.printStackTrace();
}
catch(RemoteException e)
{
e.printStackTrace();
}
while(col.hasMoreElements())
{
File obj = (File) col.nextElement();//EXCEPTION HERE*******
addRow(obj.getVector());
}
}The exception I get:
