Hi i cant seem to export using RTF & Excel. I recently downloaded DisplayTag 1.1. Im fairly new with the Display tag.

Details are given below -

The displaytag.properties file has the following details -

sort.behavior=list
sort.amount=list
basic.empty.showtable=true
basic.msg.empty_list=No results matched your criteria.

paging.banner.placement=top

paging.banner.onepage=<span class="pagelinks"></span>

export.types= csv excel xml rtf
export.excel=true
export.csv=true
export.xml=true

export.pdf=true

export.rtf=true
export.excel.class=org.displaytag.export.excel.DefaultHssfExportView

export.pdf.class=org.displaytag.export.DefaultPdfExportView

export.rtf.class=org.displaytag.export.DefaultRtfExportView

if set, file is downloaded instead of opened in the browser window

export.[mymedia].filename=

Do I have to implement the classes - DefaultHssfExportView & DefaultRtfExportView or is it available in the displaytag.jar?

Also catalina.out has the info :

INFO ExportViewFactory(<init>:61) - Initializing ExportViewFactory with type={csv,excel,xml,rtf}
INFO TableProperties(getLocaleResolverInstance:456) - No LocaleResolver configured.
INFO TableProperties(geResourceProvider:1015) - I18nResourceProvider initialized to

org.displaytag.localization.I18nJstlAdapter.

The displaytag in the jsp is :

<%@page import="org.displaytag.sample." %>
<%@page import="org.apache.commons.beanutils."%>
<%@ taglib uri="http://displaytag.sf.net" prefix="display" %>

//code and other HTML

<display:table pagesize="50" style="vlink:#3F6F9A;link:#3F6F9A;border:none;cellspacing:2;font-family:

Verdana;font-size:12;background:#D7D7D1" name="requestScope.results" id="row" export="true" >
<display:setProperty name="export.rtf.decorator" value="org.displaytag.sample.decorators.ItextTotalWrapper" />
<display:setProperty name="export.rtf.filename" value="example.rtf" />
<display:setProperty name="basic.empty.showtable" value="true" />
</display:table>

I get the following exception when I try to access the excel or rtf exports -
