Extend NavigationBean.java

[mesa2e]

Hi,

I've extended the class NavigationBean, because I don't want the final user could see 'Guest Home' Panel, in that way:

public class MyNavigationBean extends NavigationBean{
   public boolean getGuestHomeVisible()
   {
    if(authService.guestUserAuthenticationAllowed())
    {
        Node guestHome = getGuestHomeNode();
       // return guestHome != null && guestHome.hasPermission("Read");
       // Show Guest Home only to admin user
        User user = Application.getCurrentUser(FacesContext.getCurrentInstance());
        return user.isAdmin();

    } else
    {
        return false;
    }
   }
}

My question is:
If I include my class in the alfresco-web-client.jar, how can I say to Alfresco that it should use the new class?
I need to extend more classes and I wanted to know how can I configure Alfresco.

Thanks in advance,
Elena.

- Extend the class NavigationBean with your custom class (CustomNavigationBean.java)
- Compile and deploy this class in a jar placed in WEB-INF/lib
- Override the bean named "NavigationBean" with your custom bean, by inserting something like this in faces-config-custom.xml :

   <managed-bean>
      <description>A customization of default NavigationBean bean</description>
      <managed-bean-name>NavigationBean</managed-bean-name>
      <managed-bean-class>be.cediti.alfresco.web.bean.CustomNavigationBean</managed-bean-class>
      <managed-bean-scope>session</managed-bean-scope>
      <managed-property>
         <property-name>nodeService</property-name>
         <value>#{NodeService}</value>
      </managed-property>
      <managed-property>
         <property-name>searchService</property-name>
         <value>#{SearchService}</value>
      </managed-property>
      <managed-property>
         <property-name>namespaceService</property-name>
         <value>#{NamespaceService}</value>
      </managed-property>
      <managed-property>
         <property-name>cifsServer</property-name>
         <value>#{cifsServer}</value>
      </managed-property>
      <managed-property>
         <property-name>ruleService</property-name>
         <value>#{RuleService}</value>
      </managed-property>
      <managed-property>
         <property-name>userPreferencesBean</property-name>
         <value>#{UserPreferencesBean}</value>
      </managed-property>
      <managed-property>
         <property-name>authenticationService</property-name>
         <value>#{AuthenticationService}</value>
      </managed-property>
        <managed-property>
            <property-name>permissionService</property-name>
            <value>#{PermissionService}</value>
        </managed-property>
   </managed-bean>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hi Denis, Thanks for your response.
I'm try it, and i got the following errors:

javax.faces.FacesException: Could not retrieve value of component with path : {Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId: /jsp/login.jsp][Class: javax.faces.component.html.HtmlForm,Id: loginForm][Class: javax.faces.component.html.HtmlInputText,Id: user-name]}

Do I have to include the .class in the original .jar?

Thanks in advance,
Elena.

Your class (org.web.bean.MyNavigationBean) is not found.
The cleanest solution is to create your own jar and place it in a location where it will be found by the tomcat classloader (typically WEB-INF/lib).

Denis,

I had a mistake in the class package. I set the correct one, but now I get errors when I restart tomcat:

Looks like a previous Alfresco process was not fully terminated.
To be sure, try rebooting your machine…

[mesa2e]

It works!!!!

Thanks Denis, I really appreciate your help!!

Other question I have related with it would be…

What would I have to include in faces-config-custom.xml if I have to extend methods like:
UINavigator or PageTag? How can I know that?

Thanks a lot,
Elena.
