Hi,
i am trying to develop a simple JEE6 Application with JSF 2.0 as presentation layer.
The Model includes a simple inheritance association: The entity classes "Van" and "Motorbike" both extend the class "vehicle".
In order to cover this inheritance in the View, i use JSF Composite Components. I´d like to build an input form which contains the input text fields for all the attributes of the vehicle class which the derived classes have in common.
Problem #1:
My Composite File looks like this:
??<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:cc="http://java.sun.com/jsf/composite">
<!-- INTERFACE -->
<cc:interface>
<cc:attribute name="vehicle" required="true"/>
<cc:attribute name="style" required="false"/>
</cc:interface>
<!-- IMPLEMENTATION -->
<cc:implementation>
<tr>
<td>Manufacturer: </td>
<td>
<h:inputText value="#{cc.attrs.vehicle.manufacturer}"></h:inputText>
</td>
</tr>
</cc:implementation>
</html>
??
The problem occurs in the line
<h:inputText value="#{cc.attrs.vehicle.manufacturer}"></h:inputText>
when I type the "attrs." element within the expression, a "no suggestions" popup appears. But in my opinion there should appear a popup offering the elements "vehicle" and "style" as they are noted in the interface area. I googled it extensively but found no real solution. But I guess this behaviour is just the appearance of a bigger problem which i dont understand.
Problem #2: Referencing the Composite File in an JSF Page
Next, I want to use the composite component in an JSF Page, i.e. for building the input form for the "van" objects.
so i register the namespace and reference the project folder in which the composite file is contained:
?<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:rzcomp="http://java.sun.com/jsf/composite/rzcomp">
The line marked bold causes a error: "No library found for this namespace". rzcomp is the folder in the resources folder of my WAR-Module, which contains the composite file.
I googled that problem too and found something about editing the web.xml with an additional context parameter, but I did´nt really understand where the problem is.
I really hope for your help, i´m quite frustrated already :-(
P.S. I Use NetBeans 6.9.1
