[daisy] Changing the access denied page for guest

[Parisi, Lou]

This message from 2005 has information about changing the access denied
page message for the guest or logged in user.

http://lists.cocoondev.org/pipermail/daisy/2005-October/002399.html

 

I found that the reference in the old message

 
<xsl:when test="exceptionChain/throwable[1]/@class =
'org.outerj.daisy.repository.DocumentReadDeniedException' and
$httpMethod = 'GET'">

 

is no longer accurate.  In my daisy version 2.1 the installed file has
throwable[2] but this does not work.  Through trial and error I found
throwable[3] gave me the ReadDeniedException class.

 

I updated this and changed error.xsl to give one message for the guest
role and another for any other role like this:

 

<xsl:variable name="onlyGuestRole"
select="boolean($user/activeRoles/role[@name='guest']) and
count($user/activeRoles/role) = 1"/>

 

    <xsl:choose>

      <!-- special treatment for accessexceptions: let user change login
and return to original page. -->

      <xsl:when test="exceptionChain/throwable[3]/@class =
'org.outerj.daisy.repository.DocumentReadDeniedException' and
$httpMethod = 'GET'">

        <xsl:value-of select="exceptionChain/throwable[3]/@message"/>

 

        <xsl:choose>

                <xsl:when test="$onlyGuestRole">

                   <p>

                       <xsl:text>Guest role does not have access to view
project pages.  Please login.</xsl:text>

                   </p>

                   <p>

                       <a
href="{$mountPoint}/login?returnTo={urlencoder:encode($pageURI,
'UTF-8')}"><i18n:text key="error.change-login"/></a>

                   </p>

                </xsl:when>

                <xsl:otherwise>

                   <p>

                      <i18n:translate>

                      <i18n:text key="error.login-info"/>

                      <i18n:param><xsl:value-of
select="$user/name"/></i18n:param>

                      <i18n:param>

                        <xsl:call-template name="roleList">

                        <xsl:with-param name="roles"
select="$user/activeRoles"/>

                        </xsl:call-template>

                      </i18n:param>

                      </i18n:translate>

                   </p>

                </xsl:otherwise>

        </xsl:choose>
