Front-end
#1

Olá pessoal,
eu tenho uma pagina no meu sistema assim…


<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:ui="http://java.sun.com/jsf/facelets"
      xmlns:f="http://java.sun.com/jsf/core"
      xmlns:p="http://primefaces.org/ui">
    <ui:decorate template="/tema/padrao.xhtml">
        <ui:define name="centro">
                       <h:form enctype="multipart/form-data" id="envia">

                           <p:fileUpload fileUploadListener="#{fileUploadController.upload()}"  
                                 allowTypes="/(\.|\/)(mdb|sqlite|)$/" mode="advanced" sizeLimit="9999999" auto="true"/>
                          
              <p:growl id="messages" showDetail="true"/>  
            </h:form>
        </ui:define>
    </ui:decorate>
</html>

Quando eu adiciono essa configuração no web.xml da erro e eu não consigo executar a aplicação, mas quando tiro eu executo a aplicação normalmente mais não faz o upload…

<filter>

<filter-name>PrimeFaces FileUpload Filter</filter-name>

<filter-class>

org.primefaces.webapp.filter.FileUploadFilter

</filter-class>

<init-param>

<param-name>uploadDirectory</param-name>

<param-value>D:/temp</param-value>

</init-param>

<init-param>

<param-name>thresholdSize</param-name>

<param-value>10000</param-value>

</init-param>

</filter>

<filter-mapping>

<filter-name>PrimeFaces FileUpload Filter</filter-name>

<servlet-name>Faces Servlet</servlet-name>

</filter-mapping>

Eu já tenho um filter no meu web.xml… ele sem o código ai em cima ele funciona, mas porque com esse código ele não funciona ?
Meu web.xml está assim… essa configuração acima.
