Server not found in Kerberos database while getting a service url ticket

[vpouli]

hello,
I have added to my kerberos database the following principal:
"http://localhost:8080/axis/services/test" .
(It' s in a url format instead of  being in the format:
service/host at REALM.)
So, the thing is that I would like to acquire a service ticket for that
principal.
To request a service ticket I am using gss api and follow the next
steps:

class KrbClient{
main(){
....
//I have acquired the credentials from the ticket cache
...
PrincipalName serviceName = new
PrincipalName("http://localhost:8080/axis/services/test");

// create the tgs_req to ask for service tickets
sun.security.krb5.KrbTgsReq tgs_req = new
sun.security.krb5.KrbTgsReq(credentials, serviceName);

tgs_req.send();

// get tgs_rep
KrbTgsRep tgs_rep = tgs_req.getReply();
}
}

and it gets the folllowing error:

KrbException: Server not found in Kerberos database (7)
	at sun.security.krb5.KrbTgsRep.<init>(KrbTgsRep.java:67)
	at sun.security.krb5.KrbTgsReq.getReply(KrbTgsReq.java:235)

What I see, is that when I request a ticket for a service principal
which contains "//" (like in http://localhost....) it puts an escape
character '\' between '//'  and tries to find "http:/\/localhost..."
instead of "http://localhost....".

Is there something I can do about it?
