JSP, Solr - How to get fields from an Interator

Hi,

I am new to Java (though not to JavaScript or JQuery). I have a standalone JSP that gets results from Solr. In the iterator, how can I break out the fields so I can display them similar to this:

<div>ItemID: <%=result.getItemID()%></div>
<div>ItemName: <%=result.getItemName()%></div>
<div>ItemImage: <%=result.getItemImage()%></div>
<div>CategoryID: <%=result.getCategoryID()%></div>
<div>CategoryName: <%=result.getCategoryName()%></div>
<div>ParentCategoryID: <%=result.getParentCategoryID()%></div>

Here's the code:

<%@page import="org.apache.solr.client.solrj.SolrQuery"%>
<%@page import="java.util.Map"%>
<%@page import="java.util.Set"%>
<%@page import="java.util.Iterator"%>

<%@page import="org.apache.solr.client.solrj.impl.CommonsHttpSolrServer"%>
<%@page import="org.apache.solr.client.solrj.response.QueryResponse"%>
<%@page import="org.apache.solr.common.SolrDocumentList"%>
<%@page import="java.util.List"%>

	solrQuery.addFacetField("cgynam");

// here I am definitely cheating!
	solrQuery.setQuery("girl");
