Hello, if i remember me correctly, this was an problem with mime type.
you need to override CASFilter.getTicketValidator() and add following
extended url connection factory
// we need own connection factory enriching the connection by Accept:
application/xml header
HttpURLConnectionFactory urlConnectionFactory = new
XmlTypedURLConnectionFactory();
cas30ProxyTicketValidator.setURLConnectionFactory(urlConnectionFactory);
// replaces url connection factory also by proxy retriever
cas30ProxyTicketValidator.setProxyRetriever(new Cas20ProxyRetriever(serverUrl,
null, urlConnectionFactory));
/**
* Enriches the default {@link HttpsURLConnectionFactory}
* by adding the "Accept: application/xml" header to {@link URLConnection}
*/
private static class XmlTypedURLConnectionFactory implements
HttpURLConnectionFactory {
private final HttpURLConnectionFactory delegate = new
HttpsURLConnectionFactory();
@Override
public HttpURLConnection buildHttpURLConnection(URLConnection url) {
url.setRequestProperty("Accept", "application/xml");
return delegate.buildHttpURLConnection(url);
}
}
Good luck!
Regards, Gena
