How to connect to R/3 via JCo using MYSAPSSO2?

Question

Hello!
I'm developing a J2EE application who resides in an EP with Single Sign On. I have to retrieve some data from R/3, the way I want to connect is via JCo using MYSAPSSO.
I have read that is possible to connect passing MYSAPSSO2 as <i>user</i> and its value as <i>password</i>. The java code in the jsp is something like this:
javax.servlet.http.Cookie [] my_cookies = request.getCookies();
java.util.Hashtable cks = new Hashtable();
for(int i=0;i<my_cookies.length;i++){
     cks.put(my_cookies<i>.getName(),java.net.URLDecoder.decode(my_cookies<i>.getValue()));
String user = "$MYSAPSSO2$";
String pass = (String)cks.get("MYSAPSSO2");
JCO.Client conex;
JCO.Repository rep;
boolean ok=true;
conex = JCO.createClient("000",user,pass,"es","192.168.0.1","00","","");
try{
     conex.connect();
     rep = new JCO.Repository("mirep",conex);
} catch (Exception e){
     out.write("<br>"e"<br>");
     ok = false;
if (ok)
     conex.disconnect();
We are working with EP6 SP2, WAS 6.20.
The error is:
com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: Se ha recibido un ticket SSP que no se puede interpretar
(I translate you:)
RFC_ERROR_LOGON_FAILURE: unable to interpret a retrieved SSP ticket
Thank you all!!

Ok!
I have solve the problem. So, I was trying to connect via SSO within an user that was not registered in R/3 and I forgot it.
Sorry for the inconvenience.
