Question

I’m very new to JSF and Hibernate, I found some tutorials and I understood almost everything but there is something very simple I didn’t understand yet and I can`t realize by myself how to do it;

1.This is my html page

 <h:panelGrid columns="2">
   <h:outputLabel value="Title:"/>
   <h:inputText value='#{Activity.title}' />
 </h:panelGrid>

2.This is my save method at activityController

public void saveActivity(String title){
    Session session = HibernateUtil.getSessionFactory().openSession();
    Transaction transaction = null;

    try {
        transaction = session.beginTransaction();
        Activity activity = new Activity(title);
        session.save(activity);
        transaction.commit();
    } catch (HibernateException e) {
        transaction.rollback();
    }finally{
        session.close();
    }
}

My doubt is: How do I get what my user types at the OutputText in the HTML page and send it to my saveActivity method?

Answer 1

You need a Form and an Submit Button:

<h:form>
<h:panelGrid columns="2">
   <h:outputLabel value="Title:"/>
   <h:inputText value='#{activityBean.title}' />
 </h:panelGrid>
<h:commandButton action="#{activityBean.saveActivity()}" value="Save" />
</h:form>

Then, either make your Controller a Managed Bean with Annotation @SessionScoped
@ManagedBean(name = “activityBean”) or use a Class for it and give it a reference to your Controller.

Good Luck 🙂
