I would like to use displaytag in an included page but I have difficulties. I have got a main page which includes a header jspf, a menu jspf and an other jspf depending on the selected menu (on menu.jspf)
main.jspf
<html><body>
<table border="0">
<tr>
<td colspan="2"><s:include value="header.jspf"/></td>
</tr>
<tr>
<td><s:include value="menu.jspf"/></td>
<td><s:include value="%{page}"/></td>
</tr>
</table>
</body></html>
the "other" jspf (I change the value of 'page' variable in a Struts2 action)
<%@ taglib prefix="display" uri="http://displaytag.sf.net" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<link rel="stylesheet" href="./css/screen.css" type="text/css"/>
<link rel="stylesheet" href="./css/displaytag.css" type="text/css"/>
<body>
<display:table name="${usageList}" pagesize="2" requestURI="menu_admin_freq.action" sort="list" class="mars">
<display:column property="nameBackendService" title="BackendService" sortable="true"/>
<display:column property="frequency" title="Frequency" sortable="true"/>
</display:table>
</body></html>
As you can see I include a full JSP page which I think is not a good idea... However when I tried to include only a fragment (without the <html> and <body> elements) and put the taglib elements into the main.jsp the displaytag table did not appear... When I removed the <html> and <body> elements and left the taglib one then I could see a text on the webpage : "<%@ taglib prefix="display" uri="http://displaytag.sf.net" %>"
At the moment I have got a working solution (by using <html>, <body> a <%@ taglib> elements in the page that must be included) but I think mine is quite a bad design pattern. How should I sort out this?
Thanks,
Viktor
Struts2
<s:include>tag includes a result of servlet or a JSP page. If you want to include JSP fragments use JSP include directive<%@ include file="..." %>.For using
<s:include>tag rename your pages to.jspand put only taglib directive (w/o<html>,<body>) along with your table to the included pages.You should use
where
mySnippet.jspis a partial Jsp, with no DTD, no head, no body, and only the HTML fragment you need.When needed, declare in it the tag-libraries (struts-tags, etc)...
