[Former Member]

Hi all!

Hi Waldemar,

Are J2EE web application and WD running on the same server? Actually SSO ticket generated by engine automaticaly by login, so mark your WD app as reuired authentication.

Hi Waldemar,

1. Logged in portal user name should have authorization to R/3 system otherwise do user mapping for the portal user with authorized R/3 user name.

2. Login to Content Administrator using Administrator rights.

http://localhost:50000/webdynpro/welcome/Welcome.jsp

3. Navigate to corresponding application and click on JCO connection tab.

4. Click on first interface Model Data (Application data).

Select the ticket option.

5. Click on Metadata interface.

Give the Service username and password of R/3 system.

Service user name of the Destination R/3 system: Administrator has to create these users.

Make sure service user has authorizations to corresponding system.

Let me know if you need more details.

Hi Suresh

Thanks for Reply!

I created 2 destinations(Modeladata/Metadata)

Modeldata use ticket athentification.

Metadata use user and password authentification.

At the moment i'm at this point:

At EJB i want to get the JCO Connection. I do it with:

<i>IWDJCOClientConnection cc = WDSystemLandscape.getJCOClientConnection("Modeldata");</i>

When i use user and password in Modeldata of my JCO destination it works fine, but when i switch to ticket authentification i get a

WDSystemLandscapeException: Error while obtaining JCO connection.

How can i get this JCO.Destination?

Is it posible to get a JCO-Destination defined in WebDynpro Content Administrator which has a SSO ticket authentification.

Maybe i am on the wrong way!

I have allready lost much of time on this issue.

Maybe i should define one destination in J2EE Visual Administrator and use it for my J2EE web app. And define a second destination in WebDynpro content administrator which will be used for Webdynpro?

This is not the best solution, but it will work!

Anybody an Idea?

I try folowing issue now -> it was not succesfull and i don't know why

I load a J2EE Web app in the Iframe of WebDynpro app. I must login to launch WebDynpro app!

In the J2EE app i create a JCO as follows:

String user="MYSAPSSO2";

String passwd="";

try{

Cookie[] my_cockies = request.getCookies();

Hashtable htbl = new Hashtable();

for(int i=0; i<my_cockies.length;i++){

htbl.put(my_cockies.getName(),my_cockies.getValue());

}

passwd = (String)htbl.get("MYSAPSSO2");

}catch (Exception e){

passwd= "error";

}

JCO.Client cl = JCO.createClient("001",user,passwd,"DE",192.168.0.15","00","","")

cl.connect();

cl.ping();

cl.disconnect();

I start the WebDynpro application. After login i get folowing Exception:

com.sap.mw.jco.JCO$Exception: <b>User SAPSYS has no RFC authorization for function group SYST</b>

The exception occurs when JCO client try to connect.-->cl.connect();

I'm totaly confused!

Anybody an idea?

I solved it now it was a small stupid error!

I had used MYSAPSSO2 as user instead of $MYSAPSSO2$
