In addition to the other resources I listed, you should take a look at JSTL: http://java.sun.com/products/jsp/jstl/
The reference implementation for JSTL is at Jakarta taglibs: http://jakarta.apache.org/taglibs/doc/standard-doc/intro.html In particular, look at the iteration tag <c:forEach> which is roughly equivalent to Struts <logic:iterate> tag. Both can be used to generate your result table by iterating over a collection. For example, using JSTL: If 'widgetResults' is the name of a Collection of Widgets in some scope (page, request, session, application) then you could use the JSTL tags in the following extract to display a table containing the Widget details: <%@ taglib uri="http://java.sun.com/jstl/core"; prefix="c" %> <%@ taglib uri="http://java.sun.com/jstl/fmt"; prefix="fmt" %> ... <c:if test="${empty widgetResults}"> <p>No widgets found.</p> </c:if> <c:if test="${not empty widgetResults}"> <table> <tr> <th>SKU</th> <th>Color</th> <th>Size</th> <th>Description</th> <th>Price</th> </tr> <c:forEach var="widget" items="${widgetResults}"> <tr> <td><c:out value="${widget.SKU}"/></td> <td><c:out value="${widget.color}"/></td> <td><c:out value="${widget.size}"/></td> <td><c:out value="${widget.description}"/></td> <td><fmt:formatNumber type="currency" value="${widget.price}"/></td> </tr> </c:forEach> </table> </c:if> ... This will print out a row in the table for each Widget in your Collection. JSTL requires JSP 1.2 or later and you should use it in preference to the Struts tag libraries where you can.
