Using ResourceBundle with JSF Tags and loading/using locale specific
properties file.
Extending an already hosted example on JSF (version 1.0), we are going to see how to
use locale specific text in properties files and loading appropriate
properties file by using loadBundle tag from JSF core tags.
For example, if locale is set as "en_US" then by using filename/basename
as "sample", we should be able to load "sample_en_US.properties" file.
And by setting locale as "hi_IN", then automatically
"sample_hi_IN.properties" file will be loaded.

Software environment I have used for this example, so far as follows:
1. JDK 5.0.x
2. Tomcat 5.5.x
3. Eclipse 3.2
4. Apache Tomcat 6.0.18
5. List of JAR files used for this example as as follows:
5.1. commons-beanutils.jar
5.2. commons-collections.jar
5.3. commons-digester.jar
5.4. commons-logging.jar
5.5. jsf-api.jar
5.6. jsf-impl.jar
5.7. jstl.jar
5.8. standard.jar
There are two properties files "sample_en_US.properties" and
"sample_hi_IN.properties" files are placed in folder "/WEB-INF/classes".
By setting locale="en_US" as shown below in the index.jsp file,
and using loadBundle JSF Core Tag, we shall be loading "sample_en_US.properties"
file only out of these two and many more properties file (if exists).
index.jsp
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="sampleHtml" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="sampleCore" %>
<html>
<body>
<sampleCore:view locale="en_US">
<sampleCore:loadBundle basename="sample" var="s"/>
<h4><sampleHtml:outputText value="#{s.title_text}"/></h4>
<sampleHtml:messages layout="table"/>
<sampleHtml:form>
<table>
<tr><td><sampleHtml:outputText value="#{s.name_text}"/></td>
<td><sampleHtml:inputText value="#{SampleMGMTBean.txtName}"/></td></tr>
<tr><td><sampleHtml:outputText value="#{s.pass_text}"/></td>
<td><sampleHtml:inputSecret value="#{SampleMGMTBean.txtPass}"/></td></tr>
<tr><td><sampleHtml:commandButton value="Submit"
action="#{SampleMGMTBean.submitButton}"/></td>
<td><sampleHtml:commandButton value="Cancel"
action="#{SampleMGMTBean.cancelButton}"/></td></tr>
</table>
</sampleHtml:form>
</sampleCore:view>
</body>
</html>
|
sample_en_US.properties
title_text=Enrollment form:
name_text=Please enter your user name
pass_text=Pass code
and the other locale specific properties file as follows:
sample_hi_IN.properties
title_text=Likhen
name_text=Apka Naam
pass_text=Apka pahachan sankya
By changing locale="en_US" to locale="hi_IN", we should see all the
text on screen changing to those from the sample_hi_IN.properties file.
In order to run this example using browser, the URL is
for my local developent environment is as follows:
http://localhost:8080/JSF-Sample/index.
jsf
Here the web address is localhost, web application name is
JSF-Sample, If you try to use index.jsp or / at the end of this URL,
you may encounter error on page, as mentioned in the web.xml
file, the servlet URL mapping refers to
*.jsf
