[opencms-dev] SiteMap / Navigation

[Pedro Huitema]

Here is a script that is in use on our instance of OpenCMS (we're still
running 5, but the code should work fine under 6). This will output a
site map to the screen:

<%@ page session="false" import="com.opencms.flex.jsp.*" %>
<%@ taglib prefix="cms" uri="http://www.opencms.org/taglib/cms" %>
<%
	
	// Change this variable to the root folder of the project
	String rootFolder = "/WWU.CS/";

	// Obtain some page information
	com.opencms.flex.jsp.CmsJspActionElement cms = new
CmsJspActionElement(pageContext, request, response);
	String filename, foldername, filenameparam;
	filename = cms.getRequestContext().getUri();
	
	// Retrieve the folder that the file is stored in
	if ((filenameparam = request.getParameter("filename")) == null)
{
		foldername = com.opencms.file.CmsFile.getPath(filename);

	} else {
		foldername =
com.opencms.file.CmsResource.getPath(filenameparam);
		String foldernameprop = cms.property("target",
filename);
		if (foldernameprop != null) foldername = foldernameprop
+ foldername;  
	}
	
	// Setup some page constants
	String moduleFolder = "/system/modules/wwutemplates/";
	String showsource = cms.property("showsource", filename, "no");
	String targetframe = request.getParameter("targetframe");
	if (targetframe == null || "".equals(targetframe) ||
"null".equals(targetframe)) {
		targetframe = "_self";
	}
	
%>

<%!	

	String printNavigation(String navFolderName,
com.opencms.flex.jsp.CmsJspActionElement cms) {

		String returnString = "";

		java.util.ArrayList navList =
cms.getNavigation().getNavigationForFolder(navFolderName); 
		java.util.Iterator n = navList.iterator();
		
		returnString = "<ul>";
		
		while (n.hasNext()) {
		
			CmsJspNavElement ni =
(CmsJspNavElement)n.next();
			
			if (ni.getResourceName().indexOf("index.html")
== -1) {
				returnString += "<li><p><a href=\"" +
cms.link(ni.getResourceName()) + "\">" + ni.getNavText() + "</a></p>";
		
				// Display a folder   
				if (ni.isFolderLink()) {
			
					returnString +=
printNavigation(ni.getResourceName(), cms);
				
				}
			
				returnString += "</li>";
			}
			
		}		
		
		returnString += "</ul>";

		return returnString;
	
	}
%>
<%
	
	out.println("<ul><li><p><a href=\"" + cms.link(rootFolder) +
"\">Home</a></p>" + printNavigation(rootFolder, cms) + "</li></ul>");
	
%>

I hope this helps...

Hi,
    I'm not and expert in OpenCms yet but i think the api only returns 
the current navigation level. You have to recursivelly browse the tree. 
Create a java class for that propose, or (i do not recomand) make a 
metod in jsp.

Regards
