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??

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

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:




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

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



Because after all thats what you retrieve from your HashSet

i believe you meant




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.
