Hello, I'm trying to create a rest java client to authenticate in the cas. I followed the example of the documentation but it is not working. I'm trying to use a web application with jsf, what's my error. Below is my source code:

String casUrlPrefix = "http://localhost:8080/cas";

CasRestAuthenticator authenticator = new CasRestAuthenticator(casUrlPrefix);

CasRestFormClient client = new CasRestFormClient(authenticator);

// The request object must contain the CAS credentials

HttpServletRequest request = (HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();

HttpServletResponse response = (HttpServletResponse)FacesContext.getCurrentInstance().getExternalContext().getResponse();

@SuppressWarnings("unused")

Map<String,String> requestParams = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap();

final WebContext webContext = new J2EContext(request, response);

final HttpTGTProfile profile = client.requestTicketGrantingTicket((WebContext) FacesContext.getCurrentInstance().getExternalContext());

// Requisita o service ticket

final CasCredentials casCreds = client.requestServiceTicket("<SERVICE_URL>", profile);

// Valida o ticket e obtem atributos do ticket

@SuppressWarnings("unused")

final CasProfile casProfile = client.validateServiceTicket("<SERVICE_URL>", casCreds);

client.destroyTicketGrantingTicket(webContext, profile);

Hi,

What do you mean by "it is not working"? I guess you pass the CAS credentials via a basic authentication header. Where does the process stop?

Thanks.

Best regards,

Jérôme

I can not get the WebContext. In the following line in the final source code WebContext webContext = new J2EContext (request, response);

Hi,

What's the error exactly? Can you copy/paste the stack trace?

Thanks.

Best regards,
