WPS - creating a breadcrumb trail

The following code snippet shows how to render a breadcrumb trail that shows the current selection path.

<%@ taglib uri="/WEB-INF/tld/portal.tld" prefix="portal" %> <%@ page import="com.ibm.portal.model.NavigationSelectionModelHome" %> <%@ page import="com.ibm.portal.model.NavigationSelectionModelProvider" %> <%@ page import="com.ibm.portal.navigation.NavigationSelectionModel" %> <%@ page import="com.ibm.portal.navigation.NavigationNode" %> <%@ page import="com.ibm.portal.ModelException" %> <%@ page import="java.util.Iterator" %> <%@ page import="javax.naming.InitialContext" %> <%@ page import="javax.naming.Context" %> <%@ page import="javax.naming.NamingException" %> <% try{   Context ctx = new InitialContext();   NavigationSelectionModelHome home = (NavigationSelectionModelHome)   ctx.lookup("portal:service/model/NavigationSelectionModel");   if (home != null) {     NavigationSelectionModelProvider provider =     home.getNavigationSelectionModelProvider();     NavigationSelectionModel model =     provider.getNavigationSelectionModel(request, response);     for (java.util.Iterator i = model.iterator(); i.hasNext(); )     {       NavigationNode node = (NavigationNode) i.next();       if (i.hasNext()) {         %>         <a href="<portal:navigationUrl type="link" varname="<%=node%>"/>">         <portal:title varname="<%=node%>"/>         </a>         <         <%       }       else       {       %>       <wps:title varname="<%=node%>"/>       <%       }     }   } } catch (ModelException mx) { %> < p> < span style="color:#ff0000">A model exception occured</span></p> <% } catch (NamingException nx) { %> < p > < span style="color:#ff0000"> A naming exception occured</span></p > < % } %>

****************************************************************

The example uses a JNDI lookup to obtain the navigation selection model. The model is then iterated and for each node a title is produced using the <portal:title/> tag. Until the last node is reached the <portal:navigationUrl/> tag is used to generate links to the referenced pages. The code can be put in
the WebSphere Portal default theme (Default.jsp)
