Is there any mock Test were i can choice specific SCJP Objectives to do?

What are the most relevant improvement on Composite Component in JSF 2.0

I've been tough taht there are some bean type when it comes to JSF although the 1.2 does not make any distinction.

Model Bean
Backing Bean
Support Bean
Utility Bean

Does the current version has any annotation or something to deal with this??

well it is also very good idea if you want a easly mantainable web application..

Did they added a better way to parameterized the Method?? something like the JBoss-EL

<h:commandButton action="#{hotelBooking.bookHotel(hotel)}" value="Book Hotel"/>

or to create constructor args Bean with JSF something like Spring IoC does?

From what i see (or heard) the Bean are now created mostly with annotation... so my question what other changes will be on this JSF version?

Is the typicals <managed-bean> declaration tags will still be supported??

Thanks

<managed-bean> <managed-bean-name>myBean</managed-bean-name> <managed-bean-class>com.beans.MyBean</managed-bean-class> <managed-bean-scope>session</managed-bean> </managed-bean>

@ManagedBean @SessionScoped public class Foo { }

well mappedBy anotation is very simple let me give you this sceneraio:

I have a Vehicle and Driver POJO's both represent entities on the Database both of them are mapped like this:
@Entity @Table(name = "vehicle", catalog = "mycatalog") public class Vehicle implements java.io.Serializable { private String id; @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "id_transportista", nullable = false) private Driver transportista; private String description; private String color; private Float weight; .... }

@Entity @Table(name="driver",catalog="mycatalog") public class Transportista implements java.io.Serializable { private Integer idTransportista; private String nombre; private String direccion; @OneToMany(cascade=CascadeType.ALL, fetch=FetchType.LAZY, mappedBy="transportista") private Set<Vehicle> vehiculos = new HashSet<Vehicle>(0); .....

As you can see the mappedBy is the refering to a "transportista" object in Vehicle class which said something like this....

"This Set of Vehicle is OneToMany relationship with the class (Vehicle) and do a mapped Inverse mapping with an object named transportista"

So it goes to transportista and gets this

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "id_transportista", nullable = false)
private Driver transportista;


you'll see now hibernate does not have to guess about the reference and that is inverse mapping..............

try using the double backslash

D:\\PROJECT\\Gwt-eclips\\hibernateexample\\src\\roseindia\\tutorial\\hibernate\\hibernate.cfg.xml

try forcing the path file with an absolute path let see what happens something like this

File myFile = new File("C:\\Proyect\\src\hibernate.cfg.xml"); sessions = new Configuration().configure(myFile).buildSessionFactory();

let me put it clear you are kind of doing this

Here you can se it clearly that you cannot cast an object to an integer array

Object[] objectArray=new Object[10]; Integer[] integerArray=(Integer[])objectArray;

Because after all thats what you retrieve from your HashSet

for (int i = 0; i >< array.length; i++)

i believe you meant

for (int i = 0; i >< array.length; i++)


and the answer to your question is simple. in your code you have this HashSet wich add a series of Integer but the hasset it self just contains a bunch of Objects.

Second you instanciate a List named list with the previos set collections and called to the method toArray() wich always return Object[] then you try to cast but you can't beause the Object[] Array has nothing to do with the Integer[] array is just like saying Animal[] cast to Integer[] they have nothing.

i think that it might not finding the hibernate.cfg the you have it on your root source package??... can you handle over a eclipse proyect so i can see if i get the same error??

no problem i am also studying just finish chapter 6 send me a pm with your mail

i am also planning on doing it this year just finish Chapter 6.

Sorry about this is a reply to the thread

yes i can use blob you're right but i was asking a method or example to do it with JSF....

should i uploaded to the server first with inputFille??


and i want to use the inputFile dialog only in order to the user click on the image and pick one but i don't know how.....
