I am using version 5.3.5, but I think that this part was not changed.
You can do:

     CmsJspActionElement cms = new CmsJspActionElement(pageContext, 
request, response);
     CmsJspNavBuilder nav = cms.getNavigation();
     CmsJspNavElement current = nav.getNavigationForResource();

Here is my jsp for generating a tree menu:

<%@ page import="org.opencms.jsp.*" %>
<%@ page import="java.util.*" %>
<%@ page import="org.opencms.flex.CmsFlexController" %>
<%!
  void showFolder(CmsJspActionElement cms, JspWriter 
out,CmsJspNavBuilder nav,CmsJspNavElement ne,CmsJspNavElement current) 
throws java.io.IOException {
       Iterator i = 
nav.getNavigationForFolder(ne.getResourceName()).iterator();
       while (i.hasNext()) {
            CmsJspNavElement sub = (CmsJspNavElement)i.next();
            if(sub.isFolderLink()) {
                out.print("<li><a href=\"" + 
cms.link(sub.getResourceName()) + "index.html\">"+sub.getNavText()+"</a>");
 
if(current.getResourceName().startsWith(sub.getResourceName()))  {
                  out.print("<ol>");
                  showFolder(cms,out,nav,sub,current);
                  out.print("</ol>");
                }
                out.print("</li>");
             } else {
                if(sub.getFileName().startsWith("index.")) continue;
                out.print("<li><a href=\"" + 
cms.link(sub.getResourceName()) + "\">" + sub.getNavText() + "</a></li>");
             }
       }
  }
%>
<%
     CmsFlexController controller = 
(CmsFlexController)request.getAttribute(CmsFlexController.ATTRIBUTE_NAME);
     String locale = 
controller.getCmsObject().readPropertyObject(controller.getCmsObject().getRequestContext().getUri(), 
"locale", true).getValue();
     CmsJspActionElement cms = new CmsJspActionElement(pageContext, 
request, response);
     CmsJspNavBuilder nav = cms.getNavigation();
     CmsJspNavElement top = nav.getNavigationForResource("/"+locale+"/");
     CmsJspNavElement current = nav.getNavigationForResource();
%>
<ul>
<%
     showFolder(cms,out,nav,top,current);
%>
</ul>
