there is a way to change the locale for especific view in jsf?
i can try the locale via faces-config.xml, but i just wanna a specific view.
faces-config version="1.2" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xi="http://www.w3.org/2001/XInclude"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd">
<application>
<view-handler>com.sun.facelets.FaceletViewHandler</view-handler>
<locale-config>
<default-locale>es</default-locale>
<supported-locale>ca</supported-locale>
<supported-locale>en</supported-locale>
</locale-config>
You can set the locale on a per-view basis by nesting your content in a <f:view> tag that has one of its attributes, locale, for exactly this purpose:
<f:view locale="#{localeBean.selectedlocale}">
For more information consult Localization in JSF, how to remember selected locale per session instead of per request/view.

I'm new to JSF. Right now I am developing a JSF project. I have 2 properties files, configured correctly. (tested on previous Servlet/ JSP proj.)
The problem is when I try to get the value from the property file, I get just a code typed in my browser like this:
Welcome, "#{bundle.dude}"
But it should be like:
Welcome, dude
That's my problem.
My faces-config.xml:
<?xml version='1.0' encoding='UTF-8'?>
<faces-config version="2.1"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_1.xsd">
<application>
<locale-config>
<default-locale>en</default-locale>
<supported-locale>en</supported-locale>
<supported-locale>ru</supported-locale>
</locale-config>
<resource-bundle>
<base-name>i18n.MediaPortal</base-name>
<var>bundle</var>
</resource-bundle>
</application>
</faces-config>
i18n property files are located at src/main/resources/i18n/ dir
Every answer is appreciated.
Thanks in advice.

I am using Mojarra 2.1.2 and want to configure the facelet cache factory. I tried the following in my WEB-INF/faces-config.xml but it does not seem to work.
<factory>
<facelet_cache_factory>org.valuesource.custdb.web.extension.SimpleFaceletCacheFactory</facelet_cache_factory>
</factory>
You shouldn't use underscores. Use hyphens.
<facelet-cache-factory>
No one XML element of faces-config.xml uses underscores. Note that the FaceletCacheFactory was introduced in JSF 2.1, so ensure that your faces-config.xml root declaration conforms JSF 2.1:
<faces-config
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_1.xsd"
version="2.1">
How do I render JSF components based on a logged in user's role? I know the external context exposes the principals, but how should I do the rendering properly in JSF? In JSP it would be something like
<% isUserInRole(Roles.ADMIN) { %>
<button>Edit!</button>
<% } %>
How do I write this in JSF the best possible way? My best guess is the rendered attribute tied to a backing bean's method that returns a boolean, but that would introduce an irrelevant backing bean if I have to render some navigation items only for admins...
Glassfish V3.1, JSF 2.x
If your web.xml is declared as Servlet 3.0 (which implicitly relates to JSP/EL 2.2)
<?xml version="1.0" encoding="UTF-8"?>
<web-app
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">
then you can take benefit of being able to invoke methods with arguments in EL like as ExternalContext#isUserInRole():
rendered="#{facesContext.externalContext.isUserInRole('ADMIN')}"
Note that this requires a Servlet 3.0 capable container, but since you're using Glassfish 3 (which supports Servlet 3.0), it should work without any issues.
Also note that if you're using Facelets instead of JSP, then you've the HttpServletRequest available as #{request} in EL, allowing you the following shorter expression:
rendered="#{request.isUserInRole('ADMIN')}"
Conditionally displaying JSF components
Conditional rendering of non-JSF components (plain vanilla HTML and template text)
JSF: How control access and rights in JSF?
In response to #wasimbhalli, there are two reasons I have found that the expression would always return false:
The role name is case sensitive.
rendered="#{facesContext.externalContext.isUserInRole('ADMIN')}" may return false, but try
rendered="#{facesContext.externalContext.isUserInRole('admin')}", or rendered="#{facesContext.externalContext.isUserInRole('Admin')}".
You have to define your roles in both web.xml (or as annotations) and map it in glassfish-web.xml.
The following is how to specify a role in web.ml
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
<security-role>
<role-name>admin</role-name>
</security-role>
</web-app>
The following is how to map the authentication group to the role in glassfish-web.xml.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE glassfish-web-app PUBLIC "-//GlassFish.org//DTD GlassFish Application Server 3.1 Servlet 3.0//EN" "http://glassfish.org/dtds/glassfish-web-app_3_0-1.dtd">
<glassfish-web-app>
<security-role-mapping>
<role-name>admin</role-name> <!-- name defined in web.xml or annotations -->
<group-name>admin</group-name><!-- name from authentication mechanism -->
</security-role-mapping>
</glassfish-web-app>
In my testing it was necessary to do the mapping even when the names were the same, as I show in my example code. Also in my testing, I tried to only define the mapping and only to define the role in web.xml, and neither worked. I needed both, as specifying the role name in the correct case.
Store role in session attribute and just compare that using rendered attribute.
e.g. rendered="#{yoursessionbean.userRole == Roles.ADMIN}"
when you use a component from extarnal libraries (or custom component) in JSF page you add the xmlns declaration, for example:
xmlns:util="http://java.sun.com/jsf/composite/component/util
I would like to know what I have to do to use a private address in the Namaspace like this below:
xmlns:p="http://primefaces.prime.com.tr/ui"
It is something related to packages? Or it depends from the name of the .JAR that contains the components?
Thank you!
For Facelets this is definied in .taglib.xml file. In case of PrimeFaces it's /META-INF/primefaces-p.taglib.xml:
<?xml version="1.0" encoding="UTF-8"?>
<facelet-taglib xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facelettaglibrary_2_0.xsd"
version="2.0">
<namespace>http://primefaces.prime.com.tr/ui</namespace>
...
Note the <namespace>. For JSP this is definied in the .tld file, for PrimeFaces it's the /META-INF/primefaces-p.tld
<?xml version="1.0" encoding="UTF-8"?>
<taglib xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-jsptaglibrary_2_1.xsd" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.1">
<tlib-version>1.2</tlib-version>
<short-name>p</short-name>
<uri>http://primefaces.prime.com.tr/ui</uri>
...
Note the <uri>.
Defining custom components in Facelets is easy and quick but there's one thing I can't figure out.
Is it possible with Facelets to define what attributes my custom component has? I.e: I've created a component which is used in such a way:
<blue:modalWindow id="editFeesWizard" width="500" height="440" title="Wizard">
and is defined in taglib.xml as follows:
<!DOCTYPE facelet-taglib PUBLIC
"-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN"
"http://java.sun.com/dtd/facelet-taglib_1_0.dtd">
<facelet-taglib>
<namespace>...</namespace>
<tag>
<tag-name>modalWindow</tag-name>
<source>components/modalWindow.xhtml</source>
</tag>
</facelet-taglib>
Taglib doesn't contain any information on component's attributes (id, width, height, title) and IDE cannot therefore check my syntax nor can it suggest attributes while I'm typing.
I cannot find anything on this subject in Facelets documentation. Thought you could help. Thanks!
It seems there isn't a way. But even if there was, I don't think Eclipse (for example) would be able to handle it and offer autocomplete. That's why you can define a .tld, containing the attributes:
<?xml version="1.0" encoding="utf-8"?>
<taglib
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-jsptaglibrary_2_1.xsd"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.1">
......
</taglib>
Just for the sake of autocompletion. Ugly, I know.
I don't know about before, but it is possible now. Just add:
<tag>
<tag-name>mycustomtag</tag-name>
<source>tags/mycustomtag.xhtml</source>
<attribute>
<description>What does this do?!</description>
<name>attribute</name>
</attribute>
</tag>
I'm looking forward to being able to create composite components using JSF 2 and facelets; from what I've read, it seems very quick and easy, and you define what attributes your composite component accepts.
