302 is not an error. 302 is the HTTP status code for "Moved Temporarily" ( i.e. a redirect). It means that CAS sent you a request to do a redirect to a particular url (in this case your service url with the attached service ticket). You should read the response sent back and parse out the ticket.
The HttpUrlConnection class should have methods to retrieve the response. -Scott On 3/15/07, t ray <[EMAIL PROTECTED]> wrote:
Ok, I goofed. It actually says error 302. I am using httpurlconnection class. newurl = new URL( " http://localhost:8080/cas/login?username=aaa&password=aaa&service=http://localhost:8080/somestuff/<="+lt<http://localhost:8080/cas/login?username=aaa&password=aaa&service=http://localhost:8080/somestuff/<=%22+lt> ); Is the above format correct? I mean, the username, password, service and lt are all set correctly? I think something is wrong in the way I am passing the params. ----- Original Message ---- From: Scott Battaglia <[EMAIL PROTECTED]> To: Yale CAS mailing list <[email protected]> Sent: Thursday, March 15, 2007 3:48:41 PM Subject: Re: How to obtain a service ticket? What is doing the infinite redirect? Your browser or whatever you are using to the do the GET/POST? If you're not following redirects there is should be no way it can redirect. It should stop. -Scott On 3/15/07, t ray <[EMAIL PROTECTED]> wrote: > > I did set it to not follow redirects with the same results.
