I try every solution but still have this problem:

I use tomcat 7 as server.
Can you help me to find the problem?

My code below doesn't work, I'm using primefaces picklist and postconstruct annotation to init method with try catch block.
However my picklistbean is empty, I tried all the ways to make it work but none of them worked.
Can anyone provide me working example for picklist, or in my code am I missing something ?
I'm stuck to this problem for so long, I'll be glad if someone helps me.

In PostContruct,your dao class doesn't inject in your bean.Try preRenderView when you want to initialize somethings in your bean.
Also dont use tanidao = new TrvrTaniDAO(); in your bean.TaniDao should be injected by spring with Autowired.
PreRenderView Example
EDIT
Also if you should inject TrvrTaniDAO with jsf managed property.
#ManagedProperty(value = "#{TrvrTaniDAO}")
private TrvrTaniDAO tanidao;

How can I solve it?
In view you invoke saveComplexe
action="#{ComplexeController.saveComplexe}"
ComplexeController has only SaveComplexe method.
Either change to
action="#{ComplexeController.SaveComplexe}"
or rename method in ComplexeController to saveComplexe
2 Solutions:
Solution 1.
Change in test.xhtml : complexeController.saveComplexe [Notice first letter in complexeController is in smaller case]
<h:commandButton action="#{complexeController.saveComplexe}" value="Insérer un nouveau complexe"/>
<h:commandButton action="#{complexeController.updateComplexe}" value="Modifier un complexe"/>
Solution 2.
Change in ComplexeController.java:
#ManagedBean(name="ComplexeController ")
#SessionScoped
public class ComplexeController {
....
}
Read the Following Info about Configuring ManagedBeans in JSF:
There are 2 ways to use #ManagedBean to expose a Java Bean class to Managed Bean class.
Way 1.
#ManagedBean
public class ComplexeController{
....
}
In this case the bean exposed with same name but the first letter is smaller case, i.e., you can access the bean in Facelet as
#{complexeController}
Way 2.
#ManagedBean(name="myBean")
public class ComplexeController{
....
}
In this case the bean exposed with same name but the first letter is smaller case, i.e., you can access the bean in Facelet as
#{myBean}
Try to access the ManagedBean with first char to low case
e.g.
action="#{complexeController.saveComplexe}"
instead of
action="#{ComplexeController.saveComplexe}"
My JAXB parser suddenly stopped working today. It was working for several weeks. I get the following message. I haven't changed this code for several weeks. Wondering if this set up is good.
EDIT 2: Please could somebody help me! I can't figure this out.
EDIT 1:
My acceptance tests running the same code below are working fine. I believe this is a
classloading issue. I am using the JAXB and StAX in the JDK. However, when I deploy to jboss 5.1, I get the error below. Using 1.6.0_26 (locally) and 1.6.0_30 (dev server). Still puzzling over a solution.

elements are

Thanks, this is classloading issue I couldn't overcome so I abandoned JAXB.
Your PartialUnmarshaller code worked for me. Below is an alternate version that changes the skipElements method that may work better.

this.unmarshaller = JAXBContext.newInstance(clazz).createUnmarshaller();
unmarshaller.setEventHandler(new ValidationEventHandler() {
#Override
public boolean handleEvent(ValidationEvent event) {
System.out.println(event.getMessage());
return true;
}
});
this.reader = XMLInputFactory.newInstance().createXMLStreamReader(stream);
/* ignore headers */
skipElements();
/* ignore root element */
reader.nextTag();
/* if there's no tag, ignore root element's end */
skipElements();
}
public T next() throws XMLStreamException, JAXBException {
if (!hasNext())
throw new NoSuchElementException();
T value = unmarshaller.unmarshal(reader, clazz).getValue();
skipElements();
return value;

my question is when i use method isAdmin from loginController for userController to check if he is admin he can choose user groups, if he isn't admin he add default groups is member. but isAdmin from loginController return false why? why it not still data when user login?
You need to inject the bean as a managed property.
#ManagedProperty(value="#{loginController}")
private LoginController loginController;
And get rid of the new LoginController() line in the constructor. It would construct a completely separate instance of the bean, not reuse the already-created one in the session scope.
