Hi Hector
In home.jsp , you can save communities attribute in session and can use in any page.
Then in navbar-default.jsp
Use  : Community[] communities = (Community[]) session.getAttribute("communities");
any where in declare section <% ......%>

Subject: [Dspace-general] Communities list in navigation bar


I want to have a list of communities in my navigator bar in the same way
that I have in the home page. I tried to reuse the code in home.jsp page
in the navbar-default.jsp file. But the problem is that when I try to
get the communities attribute with this commands:

140: <%@ page import="org.dspace.content.Community" %>
141: <%
142:    Community[] communities = (Community[])
143:    if (communities.length != 0)
144:    {

I get a java.lang.NullPointerException in line 143. That is because the
communities attribute is not instanced in this file, but it's instanced
in the home.jsp page. Is there any way to get the communities in the
navbar-default.jsp file?
