How to get NODE properties?

Below is the sample code :

<%@page import="javax.jcr.Session,javax.jcr.Node,org.apache.sling.jcr.resource.JcrResourceUtil,
com.day.cq.tagging.Tag,
com.day.cq.tagging.TagManager,com.day.cq.tagging.JcrTagManagerFactory"
%>
<%
     //Node node;
    Session session = slingRequest.getResourceResolver().adaptTo(Session.class);
    TagManager tagManager =   sling.getService(JcrTagManagerFactory.class).getTagManager(session);
    Tag tag = tagManager.resolve("/apps/webexample_siva/components/content/contact");
    //specify the path which you want to get
    Node node = tag.adaptTo(Node.class);
    String name= node.getName();
%>
//Iterate node properties and displays node property name and value
<%
     for(PropertyIterator propeIterator = node.getProperties() ; propeIterator.hasNext();)
     {
         Property prop= propeIterator.nextProperty();
         if(!prop.getDefinition().isMultiple())
         {
             %>
             <%=prop.getName() %> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<%=prop.getString() %> <br />
             <%
         }
     }
%>
