[opencms-dev] Get all folders

[Frans Postma]

 Oliver,

Indexing refers usually to search-indexes, which you don't need for Navigation as far as I know. Could you please post the
relevant part of code you attempt to execute?

The "welcome" template in opencms6b1 is a good and simple example for this. Look at
/system/modules/welcome/elements/welcome_nav.jsp

The shortest example of navigation use I can come up with is something like this (check out the javadoc for
org.opencms.jsp.CmsJspNavBuilder method getSiteNavigation() for other call options):

//start
// must be on a jsp page, quick example.. not tested

// Create a JSP action element
CmsJspActionElement cms = new CmsJspActionElement(pageContext, request, response);

// yes you can use the static call too, 
// I prefer getNav from a known object to force-check stuff :)	 
java.util.List list = cms.getNavigation().getSiteNavigation();
java.util.Iterator i = list.iterator();

// Now build the navigation
out.println("Navigation:<br>");
while (i.hasNext()) {
    	CmsJspNavElement ne = (CmsJspNavElement)i.next();
	out.print(ne.getNavText()); // never returns null, so this is safe
	out.println("<br>");
}
out.println("end nav entries<br>");
// end example

Have fun with it and READ the javadocs, those contain the most of the opencms6 documentation! Some HowTo's and guides would be
nice yes, but all methods and such are very nicely documented in the source itself. (you might need to get 6b1 for the full
documentation, seems 6b2 doesn't have that in the zip anymore?)
