Richard,

I have already tried this, its worked with me.....

here is the code..

package com.sap;

import java.util.Hashtable;

import java.util.Iterator;

try {

treeBean = new NavigationBean();

TreeNode navigation = createNavigationTree(request);

treeBean.setOutput("Navigation Component Example");

treeBean.setTree(navigation);

request.getServletRequest().setAttribute("navigationBean", treeBean);

this.setJspName("Navigation.jsp");

} catch (NamingException e) {

throw new PageException(e);

}

}

private TreeNode createNavigationTree(IPortalComponentRequest request) throws NamingException {

TreeNode rootNode = new TreeNode("rootNode", "Navigation Tree");

rootNode.setTooltip("Click the tree node to expand/collapse it.");

INavigationService navigationService = (INavigationService) PortalRuntime.getRuntimeResources().getService(INavigationService.KEY);

NavigationNodes initialNodes = navigationService.getInitialNodes(getEnvironment(request));

Iterator initialIterator = initialNodes.iterator();

recursivelyAddChildrenToParentNode(initialIterator, request, rootNode, 0);

return rootNode;

}

private Hashtable getEnvironment(IPortalComponentRequest request) {

Hashtable environment = new Hashtable();

IUserContext userContext = request.getUser();

environment.put(INavigationConstants.ENV_PRINCIPAL, userContext);

return environment;

}

private int recursivelyAddChildrenToParentNode(Iterator navigationNodeIterator, IPortalComponentRequest request, TreeNode parentTreeNode, int nodeCount) throws NamingException {

INavigationNode childNode = (INavigationNode) initialNode.getChildren(environment);

Iterator childIterator = (Iterator) childNode.getChildren(environment);

nodeCount = recursivelyAddChildrenToParentNode(childIterator, request, childTree, nodeCount);

}

return nodeCount;

}

private void createTreeEntry(IPortalComponentRequest request, TreeNode treeNode, INavigationNode node, int nodeCount) {

String title = node.getTitle(request.getLocale());

Link l = new Link("LINK_" + nodeCount, title);

String navigationAction = "EPCM.doNavigate('" + node.getName() + "',2)";

l.setOnClientClick(navigationAction);

treeNode.setComponent(l);

}

}
