bean call in jsp

[sj...@stradefi.com]

Hi!

I am looking to call a function from my bean into my jsp page.
For example:
- Bean class: Users
- Bean class: X
- in this class X I have the function: getHobbies(username)
- in my jsp page I get all users nodes and I want to display each user with
the list of his hobbies thanks to this function getHobbies, please would you
mind telling me if it is possible? I was thinking of something like this:

<a:richList id="users-list" binding="#{UsersBean.usersRichList}"
viewMode="details" pageSize="10"
styleClass="recordSet" headerStyleClass="recordSetHeader"
rowStyleClass="recordSetRow" altRowStyleClass="recordSetRowAlt" width="100%"
value="#{Users.users}" var="b" initialSortColumn="userName"
initialSortDescending="true">

<h:selectOneMenu id="hobbies" style="width:150px" >
   <f:selectItems actionListener="#{X.getHobbies(b.username}" />   
						-->how to call the function
here
</h:selectOneMenu>

Thanks
Best
Sophie

It's not possible to call methods with functions in JSF EL, but you
should be able to use #{X.hobbyMethod}

and then use

public void hobbyMethod(ActionEvent e)
{
    b = UsersBean.getUsersRichList().getRowData();
    ...b.username.....
}

in your java code.

UsersBean.getUsersRichList() returns a UIData, not a List, by the way.



I still don't think this will do what you want as this isn't the
correct way to initialize a selectOneMenu.

Instead, you should create a getHobbies() method which returns a
SelectItems[] array.    In it, you'd iterate over your #{Users.users}
list, assigning the b.hobbies value to each label, and b as the
SelectItem value.

You might need or want to create a HobbyConverter (assuming Hobby is
the data type of B).
