[displaytag-user] Export in WebSphere Portlet

[Paslaru Narcis]

Hi all,

I thought I would give you more details on my current problem, maybe
somebody knows a solution.
I have

factory.requestHelper=org.displaytag.portlet.PortletRequestHelperFactory

in displaytag.properties

In web.xml :

    <filter>
        <filter-name>ResponseOverrideFilter</filter-name>

<filter-class>org.displaytag.filter.ResponseOverrideFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>ResponseOverrideFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

In my jsp :

<portlet:renderURL var="url">
    <portlet:param name="action" value="RaportAnalitic.do"/>
</portlet:renderURL>

  <jsp:scriptlet> request.setAttribute( "test", new ReportList() );
</jsp:scriptlet>

  <h2>Column grouping</h2>

  <display:table name="test" class="simple" export="true"
requestURI="<%=url.toString() %>" requestURIcontext="false">
    <display:column property="city" title="CITY" group="1" />
    <display:column property="project" title="PROJECT" group="2" />
    <display:column property="amount" title="HOURS" />
    <display:column property="task" title="TASK" />
  </display:table>

I am developing Struts Portlets JSR-168 under IBM WebSphere Portal.

My current error, when I click the export links is :

[9/25/09 17:11:34:199 GMT+02:00] 00000082 ServletWrappe E   SRVE0014E:
Uncaught service() exception root cause
/pagesAudit/raportanalitic/RaportAnaliticBody.jsp: Exception: [.TableTag]
Unable to reset response before returning exported data. You are not using
an export filter. Be sure that no other jsp tags are used before
display:table or refer to the displaytag documentation on how to configure
the export filter (requires j2ee 1.3).



Cheers,
Narcis
