Question

I have a problem related to JSF 2. I’m using the 2.1.4 version with a Tomcat 6 server. I’m migrating an application that was originally written for jsf 1.2. According that, every JSF managed bean for the application is declared in the faces-managed-beans.xml file. The problem comes when I try to set a property using new JSF 2 @ManagedProperty annotation. For example this code works for me.

<managed-bean>
    <managed-bean-name>navegableSessionParamsManager</managed-bean-name>
    <managed-bean-class>com.tesicnor.system.view.beans.navegable.NavegableSessionParamsManager</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>

    <managed-property>
        <property-name>_LoggedBean</property-name>
        <value>#{loggedBean}</value>
    </managed-property>
    <managed-property>
        <property-name>_LocaleBean</property-name>
        <value>#{localeBean}</value>
    </managed-property>

</managed-bean>

The session scoped navegableSessionParamsManager bean is receiving both loggedBean and localeBean values, which also are session scoped beans. However, if I use annotations I declare the three @ManagedBean and @SessionScoped, and I use @ManagedProperty(“#{loggedBean}”) and @ManagedProperty(“#{localeBean}”), but properties are not being set.

LoggedBean class.

@ManagedBean
@SessionScoped
public class LoggedBean extends BaseBean implements Observer {

 /**
 * 
 */
private static final long serialVersionUID = 1L; 
...

NavegableSessionParamsManager class

@SuppressWarnings("serial")
@ManagedBean
@SessionScoped
public class NavegableSessionParamsManager extends SystemNavegable {

@ManagedProperty("#{loggedBean}")
private LoggedBean _LoggedBean;

public void set_LoggedBean(LoggedBean _LoggedBean) {
    this._LoggedBean = _LoggedBean;
}
...

That’s my web.xml file

I don’t know what kind of advantages using annotations in JSF 2 has, but everybody is doing that. Also, can I be in trouble if I use annotations and also xml bean mappings for the same bean?

Answer 1

Finally after a while I have solved it adding *.faces and *.xhmtml servlet-mappings in my web.xml, which where not required before.

With that:

<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.faces</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>

Now annotations are working.
