set and get those attributes. We will explain
more about Managed Bean later in this section.
<h:commandButton action=”result” value=”#{message.button_text}” />
commandButton tag represents command
button component. Here again the value
attribute gets value of button_text param from “messages.properties” file. So in this example
this line prints “Submit” on button component .The action attribute is used to see which page
will be displayed next when we will press this
button. This “result” value is matched in facesconfig.
xml file in WEB- F folder where
navigation rules are defined. How to define
navigation rules in faces-config.xml file will be described later in this section. Here in this
application the next page is “result.jsp” when
submit button is pressed.
The collective output of tags used in
inputname.jsp will give rise to the first page
appeared in front of the user: Output of the
page is given below:
When above page appears to the user, user
enters name to the input text field and submits
the button, a new page “result.jsp” is
generated that welcomes the user with the user
name. The code for “result.jsp” is:
3-result.jsp:
<%@ taglib uri=”http://java.sun.com/jsf/
html” prefix=”h” %>
<%@ taglib uri=”http://java.sun.com/jsf/
core” prefix=”f” %>
<f:loadBundle
basename=”javajazzup.messages”
var=”message”/> |
|
<html>
<head><title>greeting page</title></
head>
<body>
<f:view>
<h3><h:outputText
value=”Hi,#{StoreNameBean.personName}!”
/>
<br/><h:outputText
value=”#{message.greeting_text}” /></h3>
</f:view>
</body>
</html>
Description:
First three lines are same as in “inputname.jsp” file.
<h:outputText value=”Hi, #{StoreNameBean.personName}!” />
The above line is used to access the value of personName attribute from Java Bean named “StoreNameBean” and prints this value (i.e.
person’s name) on the page.
<h:outputText
value=”#{message.greeting_text}” />
This line looks the value of greeting_text in “message.prorerties” file and prints this value
to the page Here this line prints “Welcome In
Java Jazz Up”.
Output of result.jsp:
So output will be like this (if “rose” is entered
in the text field of “inputname.jsp” page):
