[jboss-user] [Tomcat, HTTPD, Servlets & JSP] - exception thrown: passing an object from a bean to a JSP

I have a class on /lib, here is: package auxiliar; public class Tabla { public String oid; public String ip; public int frecuencia; public int inicio; public int fin; public Tabla (String oid, String ip, int frecuencia, int inicio, int fin) { this.oid = oid; this.ip = ip; this.frecuencia = frecuencia; this.inicio = inicio; this.fin = fin; } } And then I have a bean like about this: public class VerOid { ....... public ArrayList ver () { ....... ArrayList salida = new Arraylist(); ... while( rs.next() ) { salida.add(new Tabla(_oid, _ip, _frecuencia, _inicio, _fin)); ...... And at last, I have a JSP like this: <jsp:useBean id="id1" scope="session" class="bean.VerOid"/> <% ArrayList d = id1.ver(); out.println( d.size()); /////////// out.println( ( (Tabla) (d.get(0)) ).oid ); //////// ArrayList ff = new ArrayList(); ff.add(new Tabla ("1.1.","127.",3,4,5)); out.println( ( (Tabla) ff.get(0) ).frecuencia ); %> d.size no problem With ff neither. But out.println( ( (Tabla) (d.get(0)) ).oid ); thrown an exception java.lang.ClassCastException and I don't know why. I have JDK 1.4.
