Client independent JCO connection

Hi,
as far as I understand creating a JCO connector via the WebDynpro content administrator requires a specific R/3 client.
Is there a way I can set the client dynamically during runtime of my WebDynpro application ?
Regards
Metin

Hello Metin,
It is possible even to pass JCo destination through URL parameter (sap.wdarfc.useSys). So, you have many options there to manage multiple data sources.

client:- A
now i want to connect the same Webdynpro application to
Client:- B which is again in the same server as the client A.
Please help me how to handle this.
how it possible to connect a single Webdynpro application to two different clients using JCO Connection.
Please help.
Points would be rewarded to helpful answers.

Hi experts
                    We have to use wd application for both client at a same time e.g. as follow
Client A -
> Travel app--->Featches data from A for   employee hired in client A ,in same server as B
Client B -
> Travel app--->Featches data from B for   employee hired in client B , in same server as A
we are using same EP for both client but using diffrent roles for employees of both client.

How to use multiple clients within JCO?

Hi,
I'm pretty new to configuring Web Dynpro's with it's JCO connections. I have the following question.
We are using one portal (SAP EP 6.0_640 SP15) and one R/3 system (SAP ECC 5.0) with multiple clients (multiple customers who are all using the same portal).
Do I have to deploy a web dynpro for each client and maintain it's JCO connection for each client?
Or is there another way how I can set this up?
Thanks in advance.
Kind regards,
Dave Arends

Hi Dave,
Do I have to deploy a web dynpro for each client and maintain it's JCO connection for each client?
Or is there another way how I can set this up?
You dont need to deploy a web dynpro for each client . You can use same JCO connection for multiple User ID's ( multiple Clients mean multiple user ID's on the same portal ).
If this is the case then single JCo connection is enough to pull data from R/3 and show on portal page .
Thanks,
Nanda

Error while obtaining JCO connection when creating JCO connection

Hey,
im having a problem when creating a JCO connection in the Web Dynpro Content Administrator. Creating the Modeldata (Application Data Data type) JCO Worked but when creating the JCO for the RFC Metadata (Dictionary Meta data) there is a problem:
In step 3.2 Msg server connection I cannot specify a system name and logon group, only the message server can be selected with the dropdown box.
After pushing the finish button i get the following stacktrace:

Hi
Please configure your SLD. Your SLD holds the system definition. Define a SAP WebAS abap system and then try to create a Metadata connection using WebDynpro content administrator. Now you will be able to see the msg server defined in the dropdown. Also ensure that you have the message server entry in your services file.
Refer these links for SLD

Hello Rajendra,
Good to hear from u. Let me try to give a soln for this problem of yours.
I think probably the logon group has not been specified in the backend.If thats the case then do the following:
Connect to the backend server for which you are trying to create the JCO. Run the transaction SMLG. It will show u the existing logon groups. carry out the following steps if the 'PUBLIC' group is not present in the list of logon groups.
Click on the create button. In the pop-up, type the logon as 'PUBLIC'. For the instance, select the F4 help and choose the existing instance number. Click on copy and click save. Try running the transaction /nsmlg and now it should show the logon group 'PUBLIC'.
When you create the JCO connection, it should now show the logon group 'PUBLIC'.
Regards,
Prathamesh.

Thank you.

Hi Nutida,
Check your JCO connections are working properly or not.
For that go to http://<Auto-id's IP>:50000/webdynpro/welcome
there, click on content administrator.
here you can find your JCO connections by clicking on Maintain JCO connections.
Test your JCO connections here.

Can't create JCO connection in Portal7 for ESS1.0

Hi,
I am in the Process of setting up ESS/MSS Rel 1.0 in Portal 7. The Portal is a WebAS ABAP+JAVA system.
First step after installing Portal, I configured the SLD and created the Technical systems. The sld is running and I have tested the sld from the Content Administrator->WebDynpro-> check SLD. It results sld successfully tested and I am able to start the sld also.
After that I deployed the Business packages for ESS/MSS and selfservices via SDM.
Now I am trying to create the JCO connection in the Content Administrator->WebDynpro->create/maintain JCO Connections, it throws the following error

How to create a model and JCO connection

Hi all,
The Userid and Password given while creating new model at Singleserver/Load balancing tab should be same as the userid and password given while creating JCO connection. i.e in JCO creation while mapping modeldata to Application data and Metadata to metadata we will give some userid and password.
will those 2 userids and passwords should be same.
the error which i am getting is
com.sap.tc.webdynpro.modelimpl.dynamicrfc.WDDynamicRFCExecuteException: Error connecting using JCO.Client: null
Regards
Padma N

2 userids and passwords need not be same
i got similar problem and this is how i resolved
this is because jco connections are Using SSO and the user who is accessing that webdynpro application is not present in the backend system.
please make sure user is there in the backend system from which you are getting data

Model and MetaData configarations in JCO Connection

Hi all,
while creating new model i used Load Balance option instead of Single Server.So while creating JCO connection what should be selected for ApplicationData and MetaData radio buttons.The error which i am got aftet deploying and running is
com.sap.tc.webdynpro.modelimpl.dynamicrfc.WDDynamicRFCExecuteException: Error connecting using JCO.Client: null
Is this error is because of LoadBalance configarartion while creating JCO for Destinations or at the client num which we gave at the starting step of creating JCO
Regards
Padma N

Hi,
First You Configure SLD Correctly.If You Have ECC And BW.You Maintaing Two WEBAS ABAP Systems.
You Create WEB AS ABAP System In SLD And Maintain Connection Properties Of ECC.And
Similarly For BW Also.

JCO Connection Problem

Hi Experts,
This is not related to Java Web Dynpro directly.
We are encountering strange behavior with respect to JCo Destination.
Up to yesterday we had no problems with JCo. But when we tried to run run a Web Dynpro application, it
was not able to extract data from SAP backend.
On further investigation it was found out that JCo Destination test is failing. Following is the error when we
tried to test JCo Destination:
com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: Client 100 is not available in this system
Backend is working fine with username and password in the client. Connection from ABAP server to
the the problematic ABAP server is also working (SM59). But connection from any Java portal to ABAP
server is not working.
Has anybody encountered this problem?
Best Regards,
Pramod

Hi Promod,
It would be some Username and password issue. If you manage to change them you issue will be resolved. Have a look at the the following useful discussion. It would be helpful for you.
JCO Connection Error
Also have a look at the following Wiki for troubleshooting the RFC Communication problems with Java Connectors.
https://www.sdn.sap.com/irj/scn/wiki?path=/display/ep/troubleshooting%252bsap%252bjava%252bconnector%252b(JCo)
I hope this helps you.

Gopal.
