boa tarde pessoal, to com o seguinte problema com o DisplayTag:
antes de tudo quero dizer que ja procurei muito sobre isso, inclusive aqui no forum e nesse link que tem aqui no GUJ.
http://forum.mentaframework.org/posts/list/0/1371.page#15975
dito isso:
Fiz as configurações que essa mensagem acima recomenda…mas mesmo assim está apresentando o seguinte erro
Server Error
--------------------------------------------------------------------------------
O servidor encontrou uma condição inesperada que o impediu de cumprir o pedido: 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).
alguma luz?..
Você ta utilizando o atributo para exportar, para excel, xml … ?
Poste o código da sua displayTag caso possível.
[]'s
<display:table requestURI="" pagesize="15" id="item" name="itensGrupoConta"
export="true" style="width: 100%; ">
<display:column property="descricaoGrupo" title="Grupo"
class="defaultTdSemCor" headerClass="label" />
<display:column style="width:330px" property="codigoDescricaoConta"
title="Conta" class="defaultTdSemCor" headerClass="label" />
</display:table>
ai…
no meu 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>*.do</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>ResponseOverrideFilter</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
Então no meu caso, eu sempre usei a displayTag sem mapear o filtro no web.xml
<filter-class>org.displaytag.filter.ResponseOverrideFilter</filter-class>
Você tem a real necessidade de passar por esse filtro ?
Segue minha displayTag usando export para vc comparar:
<display:table name="${clientes}" id="cliente"
defaultsort="1" pagesize="5" width="100%" export="true">
<display:setProperty name="export.types" value="excel"/>
<display:setProperty name="export.excel" value="true"/>
<display:setProperty name="export.csv" value="false"/>
<display:setProperty name="export.xml" value="false"/>
<display:setProperty name="export.excel.include_header" value="true"/>
<display:setProperty name="export.excel.filename" value="ListaAniversariantes"/>
<display:column property="id" sortable="true" title="ID" style="text-align: center"/>
<display:column sortable="true" title="Nome" property="nome" style="text-align: center">
</display:column>
<display:column sortable="true" title="Média de Compra" sortProperty="mediaCompra" style="text-align: center">
<fmt:setLocale value="pt_BR" />
<fmt:formatNumber currencySymbol="R$" maxFractionDigits="2"
value="${cliente.mediaCompra}" />
</display:column>
<display:column sortable="true" title="Data Cadastro" style="text-align: center">
<fmt:formatDate value="${cliente.dataCadastro}" pattern="dd/MM/yyyy" />
</display:column>
</display:table>
E no meu web.xml contém apenas os mapeamentos para o Struts.
