I keep getting the attached stack trace when I try to forward the ticket
returned by
principal.getProxyTicketFor("https://phobos.callutheran.edu:8443/cas/clearPass";)
to clearPass. My servlet is almost identical to
http://www.ja-sig.org/wiki/display/CASC/JA-SIG+Java+Client+Simple+WebApp+Sample
( http://www.ja-sig.org/wiki/download/attachments/13569483/mywebapp.war
) except instead of trying to display the proxy ticket in getpt.jsp I am
doing the following:
URL clearPassUrl = new URL(targetService + "?ticket=" + ticket +
"&service=" + URLEncoder.encode(targetService, "UTF-8"));
URLConnection clearPassConnection = clearPassUrl.openConnection();
BufferedReader in = new BufferedReader( new
InputStreamReader(clearPassConnection.getInputStream()) );
String inputLine;
String message = "";
while ((inputLine = in.readLine()) != null) {
message += inputLine + "\n";
}
in.close();
I am not sure of the code above is correct but its the only example I
was able to find (
http://github.com/wgthom/CasOwa/blob/master/CasOwaAuthHandler.cs ) for
interfacing with the clearPass service. Does anyone know what I might
be doing wrong or a better way to work with clearPass?
