Not really related to WW in any way, but the way I do it is by setting a
request attribute from the "body" JSP, and then use that attribute from
the "menu" JSP:
decorator.jsp:
<table>
<tr>
<td><%@ include file="../includes/menu.jsp"%></td>
<td><decorator:body/></td>
</tr>
</table>
some-page.jsp
<%
request.setAttribute("current_view_name", "some-page");
%>
<html>
<yadda yadda />
</html>
some-other-page.jsp
<%
request.setAttribute("current_view_name", "some-other-page");
%>
<html>
<yadda again />
</html>
menu.jsp
<%!
String buildLink(HttpServletRequest req, String name, String url,
String viewName)
{
boolean isCurrentPage =
viewName.equals((String)req.getAttribute("current_view_name"));
StringBuffer buff = new StringBuffer();
if( !isCurrentPage ){
buff.append("<a href=\"").append(url).append("\">");
}
buff.append(name);
if( !isCurrentPage ){
buff.append("</a>");
}
return buff.toString();
}
%>
<ul>
<li>
<%=buildLink(request, "SomePage", "some.action", "some-page"%>
</li>
<li>
<%=buildLink(request, "SomeOtherPage", "someother.action",
"some-other-page)%>
</li>
</ul>
The "strategy" can very likely be better encapsulated in custom taglibs
or ww-actions, but IMO it's not something that WW should provide.
