Inserting multiple datas in 1 entity in a page

i have a CRUD generated create form:

<div class="create-form">
    <h:form>
        <h:inputText id="name" value="#{pointController.selected.name}" title="#{bundle.CreatePointTitle_name}" required="true" />

        <h:inputText id="term" value="#{pointController.selected.term}" title="#{bundle.CreatePointTitle_term}" required="true" />

        <p:commandButton styleClass="btn" action="#{pointController.create}" value="#{bundle.CreatePointSaveLink}" />
    </h:form>
</div>
<button>add new form</button>

i have a button that if clicked it will create another form same as above using javascript. (2 inputText, name and term)

my goal is, with 2 or more forms, depending how many forms the user wants, with 1 commandButton that is clicked it will insert everything in the database.

example:

first form: name = first form test, term = first form testterm
2nd form: name = 2nd form test, term= 2nd form testterm

after clicking the command button

2 rows will be inserted in the same table in the database.

but i'm not sure what would be the structure for page for this.

You can't send data from many forms in a single request using JSF components, you should serialize all the data and send it manually. It would be better to have a List<Item> and every time you click in the button it will create a new item on the list and update an UIContainer that will display the items of the list.

This would be a start example of the above:

@ManagedBean
@ViewScoped
public class ItemBean {
    private List<Item> lstItem;

    public ItemBean() {
        lstItem = new ArrayList<Item>();
        addItem();
    }
    //getters and setter...

    public void addItem() {
        lstItem.add(new Item());
    }

    public void saveData() {
        //you can inject the service as an EJB or however you think would be better...
        ItemService itemService = new ItemService();
        itemService.save(lstItem);
    }
}

JSF code (<h:body> content only):

<h:form id="frmItems">
    <h:panelGrid id="pnlItems">
        <ui:repeat value="#{itemBean.lstItem}" var="item">
            Enter item name
            <h:inputText value="#{item.name}" />
            <br />
            Enter item description
            <h:inputText value="#{item.description}" />
            <br />
            <br />
        </ui:repeat>
    </h:panelGrid>
    <p:commandButton value="Add new item" action="#{itemBean.addItem}"
        update="pnlItems" />
    <p:commandButton value="Save data" action="#{itemBean.saveData}" />
</h:form>
