I was able to get a work-around operational by testing on the attribute
key, but can anyone shed light on why the following test wouldn't work in
the JSP?
<c:when test="${attr.value.class.simpleName == 'String'}">
When I try this I get a JasperException
(stacktrace<http://community.middlebury.edu/~afranco/notes/attr-value-class-simplename_stacktrace.txt>)
that seems to indicate that the attra.value isn't a string, but rather an
array of characters. Shouldn't the SimplePrinciple be returning typed
attributes? Here's what I'm seeing in SimplePrincipal.getAttributes():
http://community.middlebury.edu/~afranco/notes/SimplePrinciple-attributes.png
Here is the full casServiceValidationSuccess.jsp I'm trying to use, but is
failing:
<%@ page session="false" %><%@ taglib prefix="c" uri="
http://java.sun.com/jsp/jstl/core"; %><%@ taglib uri="
http://java.sun.com/jsp/jstl/functions"; prefix="fn" %><cas:serviceResponse
xmlns:cas='http://www.yale.edu/tp/cas'>
<cas:authenticationSuccess>
<cas:user>${fn:escapeXml(assertion.chainedAuthentications[fn:length(assertion.chainedAuthentications)-1].
principal.id)}</cas:user>
<c:forEach var="auth" items="${assertion.chainedAuthentications}">
<c:forEach var="attr" items="${auth.principal.attributes}" >
<c:choose>
<c:when test="${attr.value.class.simpleName ==
'String'}">
<cas:attribute name="${fn:escapeXml(attr.key)}"
value="${fn:escapeXml(attr.value)}"/>
</c:when>
<c:otherwise>
<c:forEach var="attrVal" items="${attr.value}">
<cas:attribute name="${fn:escapeXml(attr.key)}"
value="${fn:escapeXml(attrVal)}"/>
</c:forEach>
</c:otherwise>
</c:choose>
</c:forEach>
</c:forEach>
<c:if test="${not empty pgtIou}">
<cas:proxyGrantingTicket>${pgtIou}</cas:proxyGrantingTicket>
</c:if>
<c:if test="${fn:length(assertion.chainedAuthentications) > 1}">
<cas:proxies>
<c:forEach var="proxy" items="${assertion.chainedAuthentications}"
varStatus="loopStatus" begin="0"
end="${fn:length(assertion.chainedAuthentications)-2}" step="1">
<cas:proxy>${fn:escapeXml(proxy.principal.id)}</cas:proxy>
</c:forEach>
</cas:proxies>
</c:if>
</cas:authenticationSuccess>
</cas:serviceResponse>
In case there really isn't a way to differentiate the attribute types in
the JSP, I was able to hack around it by testing for certain attribute keys
I know to be multi-valued. It's not elegant, but in case it helps someone
with a similar problem, here it is:
<%@ page session="false" %><%@ taglib prefix="c" uri="
http://java.sun.com/jsp/jstl/core"; %><%@ taglib uri="
http://java.sun.com/jsp/jstl/functions"; prefix="fn" %><cas:serviceResponse
xmlns:cas='http://www.yale.edu/tp/cas'>
<cas:authenticationSuccess>
<cas:user>${fn:escapeXml(assertion.chainedAuthentications[fn:length(assertion.chainedAuthentications)-1].
principal.id)}</cas:user>
<c:forEach var="auth" items="${assertion.chainedAuthentications}">
<c:forEach var="attr" items="${auth.principal.attributes}" >
<c:choose>
<c:when test="${attr.key == 'MemberOf'}">
<c:forEach var="attrVal" items="${attr.value}">
<cas:attribute name="${fn:escapeXml(attr.key)}"
value="${fn:escapeXml(attrVal)}"/>
</c:forEach>
</c:when>
<c:otherwise>
<cas:attribute name="${fn:escapeXml(attr.key)}"
value="${fn:escapeXml(attr.value)}"/>
</c:otherwise>
</c:choose>
</c:forEach>
</c:forEach>
<c:if test="${not empty pgtIou}">
<cas:proxyGrantingTicket>${pgtIou}</cas:proxyGrantingTicket>
</c:if>
<c:if test="${fn:length(assertion.chainedAuthentications) > 1}">
<cas:proxies>
<c:forEach var="proxy" items="${assertion.chainedAuthentications}"
varStatus="loopStatus" begin="0"
end="${fn:length(assertion.chainedAuthentications)-2}" step="1">
<cas:proxy>${fn:escapeXml(proxy.principal.id)}</cas:proxy>
</c:forEach>
</cas:proxies>
</c:if>
</cas:authenticationSuccess>
</cas:serviceResponse>
