Connect to rfc model

Hi
I have imported a sample flight test application with some adaptive rfc models in to the workspace. I also configured the jco connections? Can anyone give me information on how to link the models with the connections?
Thanks

Hi VIdyadhar,
It can be done while creating the model itself. u can check these documents
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/user-interface-technology/webdynpro/wd%20java/wdjava%20tutorials%20and%20articles%20archive/creating%20a%20web%20dynpro%20application%20accessing%20abap%20functions.pdf
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/526bd490-0201-0010-038e-d3ff7eb1d16e
In case u have already created the model, follow this link

Should I have one JCo connection per RFC model?

Hello SDN,
I got a JCo doubt.
Should I have one JCo connection per RFC model in a DC? or Can I have the same JCo connection for several models in such Web Dynpro Development Component?
I will appreciate any help.
Thank you.

Hi Gustavo,
Ideally, we use one JCo connection for all the models in all the DC's in a big project.
If you see the SAP delivered XSS/ESS/MSS solutions they are also using one JCO (SAP_R3_Human_Resources) for all the dc's in one solution.
Suppose you are not using SSO and you have different models with different JCO, now if you want to change the backend client, you have to change all the JCO connections.
So having one JCO, helps easy maintenance of connections across different applications in a big project/solution.

Shubham

Hi ,
I think SLD,s/w Catalog and Creating Logical Systems were Configured,
Go through the Following Steps Like,
-- General Data, Enter the Client of the System and Client No. (JCo Connection is Pointing to)
--J2EE Cluster, Select the J2EE Cluster you wish the JCo destination to be assigned
-- Select the Destination Type, Either Application/Dictionary data
-- Appl.Server, You may only select Servers/Logon Groups From the Drop down list that have first been defined as technical Systems in SLD.
-- Message Server, Application Data JCo destination is connected must have atleast one logon group.( if this is not done ,use SMLG transaction code to create in SAP System)
--Security, If you have selected connection Type as Application Data , then in the Security Screen you would appear Authentication Techniques and select a appropriate one .
if you have selected connection type as a Dictionary meta data then provide User Name and Password
If this is useful to you ,don't forget to award Points

Dynamic JCo Connection with Adaptive RFC Model 2

Hi gurus,
I'm trying to dinamically change a model data connector inside my web dynpro. I'm using an Adaptive RFC Model 2 to communicate with the R/3 backend. I've found that is possible to change the connector modifiyng the code inside the web dynpro. In detail I've found this example:
IWDDynamicRFCModel model1 = (IWDDynamicRFCModel) WDModelFactory.getModelInstance(Model1.class);
I put this code into wdDoInit method but I get the following error:
"<comp_name>.wdDoInit failed to create or init instance of model 'model_name' in scope NO_SCOPE with instanceId 'null'"
Furthermore I've used the deprecated Adaptive RFC Model and when I instantiate a model, ModelName m=new ModelName(), I see that the methods m.setJcoClient(client) and m.setSystemName(systemName) are visible, while when I try to do the same with Adaptive RFC Model 2, with my model m, the methods before there aren't.
So this is my question: is it possible to change data connector dinamically with Adaptive RFC Model 2?
Thanks a lot

Dear Lukinho,
You may try this ;
try {
IWDJCOClientConnection clientCon = WDSystemLandscape.getJCOClientConnection("<name of the JCO connection>");
String clientName = clientCon.getClientName();
String lang = clientCon.getLanguage();
String passowrd = clientCon.getPassword();
String sysID = clientCon.getSystemIdentifier();
String user = clientCon.getUser();
//etc...
} catch (WDSystemLandscapeException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
I got this code from the thread [Multiple Client Logon in JCO |Re: Multiple Client Logon in JCO;
Also have a look at this thread
[JCo Destination |Re: JCo Destination;
Hope it helps!!

Error in wizard to create new RFC model: connect to message server failed

Hi,
I am trying to create a new RFC model in my Web Dynpro project in NWDS. In the wizard, I reach the step where I am required to enter the SAP login information. I then enter the details in the Load Balancing tab and click Next. The error message I get is:
Connect to message server failed
Connect_PM MSHOST=****, R3NAME=*, GROUP=**
LOCATION CPIC (TCP/IP) on local host ***
ERROR service '***" unknown
(Note: the *** are client-specific and therefore confidential info so I am removing them).
The thing is, a colleague of mine is also doing the same thing, but he is not encountering this error.
Can someone help me troubleshoot this?

Hi
The user you use to connect in the RFC should have the authorization to S_RFC. In the Duet installation guide look for the section about defining a system user ID in UME. This section has details about the authorization required for the user.
Thanks

Error while creating a Adaptive RFC Model

Hi all,
I am trying to create a Model using a Adaptive RFC Model, I assign a Model name and the logical system names, enter the details in SAP Logon Information for the Single server,here it gives me a Gateway error. What could be the issue here?
NB: In the Host Name , I tried with both the Host name of the r/3 server and also with the SAProuter string ( as we have the server at other place) ,still it doesnt work. and I am able to login to the R/3 system from the SAPLogon GUI from my desktop normally.
Is there any issue of the firewall related to this, if so whats the port number that should be opened so that i can connect to the r/3 system get the list of BAPIs present there into my Webdynpro application .
Need help on this
Regards,
Vijay

Hi Lohi n Gopi ,
I have checked out with the your given suggestion of trying with the host name as well as IP address and also typing all the details,without copy pasting the details . In both the cases it gave the " Connect to gateway failed " error mesg.
But one intersting thing here that i observered when trying with hostname, IP address, or SAProuter string is as follows .
with IP address
Connect to SAP gateway failed
Connect_PM GWHOST="ipaddress",GWSERV=sapgw10,ASHOST="ipaddress",SYSNR=10
LOCATION CPIC(TCP/IP) on local host
ERROR patner not reached(host "ipaddress",service=3310)
with SAProuterString
Connect to SAP gateway failed
Connect_PM GWHOST="SAProuterString",GWSERV=sapgw10,ASHOST="SAProuterString",SYSNR=10
LOCATION SAPRouter on " some HostName"
ERROR hostname unknown
with HostName
Connect to SAP gateway failed
Connect_PM GWHOST="hostname",GWSERV=sapgw10,ASHOST="hostname",SYSNR=10
LOCATION CPIC(TCP/IP) on local host
ERROR hostname "hostname " unknown
Is there any firewall port blocking issue here ?if so , whats the port that needs to be opened ?
Appreciate your help.

Error while importing a Adaptive RFC Model

Experts,
I am trying to import an Adaptive RFC Model. Before importing I need to speciy the connection parameters in the import wizard. I am using the single server method to connect and have specified all the parameters correctly. I have not specified a SAP router as I am using a test system. when I click next on the Model import wizard I get an error.

sapgw<Inst.No>s 48<Inst.No>/tcp
where <Inst.No> = System Number of your R/3 system(00 or 01...)

ip of the server name of the server....

Login failed error while importing an adaptive RFC model

Hi there,
I am trying to import a adaptive RFC model for a BAPI from a 46D system, to which I have connected using VPN from my WAS J2EE server. I have given the login details as Single server(Not load balancing), and given the user login details. However, I am not able to proceed further because it gives me the error 'Name or password is incorrect, please re-enter'. This is strange because I am giving the correct name and password, and I am able to login to this system through SAP GUI using same logon credentials.
I am confused as to what it is expecting to move forward. I have tried changing case of the user name, restarting my WAS etc. The client is correct, and the login language is EN.
Could anybody have any clues or have you faced a similar problem?
thanks in advance,
LM

I have had the same problem.
I think whoever programmed the logon routine at that point should be fired immediately and banned from programming for life! Logging on is a very basic and well-understood task, and programmed gozillions of times since 1940s. Common sense and unwritten rules of programming dictate simply if you make something case-sensitive, then you should accept an input in its original form (i.e. password in smalls, or whatever) but not change it to uppercase and then work case-sensitively. Either this, or you program everything case-insensitively.
Fire that programmer or give him to us gollumvoice

How to find out the destination of an "Adaptive RFC Model - DEPRECATED"

Hi All,
How to find out the destination of an "Adaptive RFC Model - DEPRECATED" of an running application
and Where is the destination created in the server .
I have got the code of the running project from NWDI .
Thanks in Advance
Regards
Piyas Kumar

Hi,
I am not sure I fully understand the question, but as per the guide
http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/50f7192d-2808-2d10-189b-df3fa5f71abf
Excerpt from Page 7
Caveat Confector!1
ARFC1 destinations were created using the Web Dynpro Content Administrator tool. This tool is
still available for compatibility reasons, but the destinations it creates are not used by ARFC2
models!
Instead, you should use the u201CDestinationsu201D tool found on the Configuration Management screen of
the NetWeaver Administrator.
Therefore I think if you look up the application in the WD content Admin, there you can find out what kind of JCO/RFC connections are belonging to it. You can find it on http://<host>:<port>/webdynpro/dispatcher/sap.com/tcwdtools/Explorer
Browse your application here, and then select the JCO Connections tab on the right hand side.
I hope this helps.
Best Regards,
Ervin

Importing adaptive RFC model in NWDS CE 7.1 doesn't work

Dear all,
I am unable to create an adaptive RFC model in my Web dynpro DC in NWDS CE 7.1.
This is what happends:
I select create model from the web dynpro, fill in name and jco destinations on the first page and move to the second page where I fill in SAP login information.
After clicking next I come to "Select RFC modules", but I never see the studio logging in to the server system. The result is that I dont find any function modules when i click search.
I am new to NWDS 7.1 so I suppose there is a setting that I have missed.
Have anyone else experienced the same problem and solved it?
I currently have an old SAP system (NW04) and a new system (NWCE7.1). On my PC I have installed NWDS 04 and NWDS CE7.1. The old studio can connect to both the new and old backend system just fine but the new studio cant connect to any of them.
I am very grateful for any help or pointers in the right direction.
Sincerely,
Richard Linnander

Never mind. I solved this myself.
It was caused by DLL-hell. I was running an old version of librfc32.dll that was for NWDS 04. Works fine with the version that comes fresh with install of NWDS CE 7.1

Error in Import Adaptive RFC Model

Hi SDN,
I am trying to develop an application using Import Adaptive RFC Model, while creating a model i could not able to connect to the backend system after giving the single server parameters. When i click on the next button a pop up is displayed with an error message *"User Name or Password wrong" *.
But i could able to login to R/3 with the same userid and password from SAP logon pad.
Really i am at Six and Seven's to trace out this error. Please suggest me how to overcome this error and create the model succesfully.
Regards
Basha

Hi Praveen & Chaitanya
Thanks for your quick response and informative threads.
Actually in order to import an adaptive rfc model
I have right clicked the model node to create a model and given the model name,package name,model data and metadata names and clicked next button. Then in the next screen
Tab Strip -> Single Server:
Host name :
System Number :
client details:
Tab Strip -> Load balancing:
System :
Message Server:
System Name:
Group:
(in Tcode: SLMG i have added the group public also)
client details:
After entering the required details either in Single Server or Load balancing and clicked the next button I could not able estabilish a connection to the backend R/3 and get the list of Bapi's or RFc's. Instead i am getting a pop up message "User Name or Password Wrong". I could not able to proceed from here.
But with the same above parameters i could able to logon to R/3 from SAP Logon Pad. I have tried by giving the user name in Cap's and small letters but no use.
As i was strucked at the intial step while creating the model but not during the execution of the program, as far as my knowledge is concerned i think we no need to worry on SLD or JCO connections during the creation of the model. Please correct me if i am wrong and suggest me to rectify the error.

Basha

Access rfc-model over an scheduled message-driven-bean

Hi there
The problem is, that I've got a WebDynPro Project in which one a RFC-Model exists.
In this project I do also have my singleton-classes which one hold the data of the rfc-model
during the period of their lifetime. I did publish the singleton-pointer/reference in the jndi.
Within the SAP Java Scheduler (there is a tutorial @ sdn) I've created a ejb which
should run for example every hour. This one is of course in an other container (because of that i do use the jndi)
So i run the ejb and get the reference of my singleton over the jndi. Till here every
thing works fine!
Now I do call a method of the singleton (in the ejb) which should open an jco-connection over the existing model and the following error appears:
Couldn't load new data! Problem found:
Unable to access Task Scope in DynamicRFCModelClass. Either run in Engine, or turn Test mode on in WDModelFactory!
I read already something about this test-mode, but it isn't recommended at all to activate this mode!
So the J2EE has the reference but can't access the task scope. I tried to select the task-scope with the ejb, but
i didn't found any solution till now.
Has anybody an idea?
Regards Marco

JCO$Exception when creating RFC model

Hi all,
I'm getting this fatal error when creating an RFC model in Web Dynpro for Java (connecting to a BW system):
com.sap.mw.JCO$Exception: Missing R3NAME=... or ASHOST=... in connect_param in RfcOpenEx
I have absolutely no clue what's going wrong...
The RFC model gets created, but when running the application it doesn't work...
Any help appreciated!
Jeroen

Raj,
Thanks for your reply.
I had already solved the problem... After a long time I found out it was due to the language: when creating an RFC model one should use the language of SLD.
kind regards,
Jeroen

Problem in using the RFC model in webdynpro aplication

Hi,
I am trying to access FM CRIF_GET_EMPLOYEE_FOR_USER from the backend system in webdynpro application in two different ways
1.By using JCO classes in a java class
IRepository repository;
public int getPernr(String user)
int ret = 0;
String user = "SRESP5";
double pool = Math.random()*100000000;
//     the repository we gonna be using
try{
//      Add a connection pool for the specified system
     wdThis.wdGetAPI().getComponent().getMessageManager().reportSuccess(""+pool);
JCO.addClientPool(
"DE1", //alias for this pool

//      Create a new repository
repository = JCO.createRepository(
"MYRepository", "DE1");
wdThis.wdGetAPI().getComponent().getMessageManager().reportSuccess(
     "ExceptionwwwwwwxSS");
catch(JCO.Exception ex) {
wdThis.wdGetAPI().getComponent().getMessageManager().reportSuccess(
"Exceptionwwwwwwx"+ex.getMessage());
JCO.Client client =
null;
try{
//      Get a function template from the repository
     wdThis.wdGetAPI().getComponent().getMessageManager().reportSuccess(
     "SSS");
//     wdThis.wdGetAPI().getComponent().getMessageManager().reportSuccess("ExceptWWWW");
JCO.Function function = repository.getFunctionTemplate(
"Z_CRIF_GET_EMPLOYEE_FOR_USER").getFunction();
wdThis.wdGetAPI().getComponent().getMessageManager().reportSuccess(
     "ddd"+function);
     wdThis.wdGetAPI().getComponent().getMessageManager().reportSuccess("ExceptioWWW");
//      Fill in input parameters
JCO.ParameterList input = function.getImportParameterList();
input.setValue(user,

//     input.setValue(String.valueOf(new Date()), "BEGINDATE" );
//     input.setValue(String.valueOf(new Date()), "ENDDATE" );
//      Get a client from the pool
     wdThis.wdGetAPI().getComponent().getMessageManager().reportSuccess("ExceptionQQ");
client = JCO.getClient(

//     wdThis.wdGetAPI().getComponent().getMessageManager().reportSuccess("Exception");
//      Execute function the remote system
try{
   client.execute(function);
}catch(Exception e){

finally{
//      Always release client !!!
//JCO.releaseClient(client);
JCO.removeClientPool("DE1");
//     try
return ret;
it is returning the PERNR of the username passed as an input parameter.
2.But when I am trying to use an adaptive RFC model and it is giving NO_EMPLOYEENUMBER_FOUND
here is the code

Hi,
Change this line of code:
wdContext.nodeZ_cr().bind(input);
to
wdContext.nodeZ_Crif_Get_Employee_For_User_Input().bind(input);
Try executing your application now.

RFC model creation problem in NDS

Hi All,
I am facing a strange problem while creating a RFC model in NDS.
After providing all the logon informations to server, the editor says "Connect to SAP gaetway failed. Unknown hostname..."
Where as I can connect to SAP system through the SAP gui using the same logon details.
The Hosts file does have entry for the hostname.....Tried using a newer 7.0.10 version, but problem still persists.......
What might be the loose end here!!!!!!!!
As far I know, NDS uses tcp/ip protocol to connect to servers & the Host file entries should help it in getting connected to SAP.....
Does it use some other layer to connect??? HTTP???
Any pointers are welcome. Thanks in advance..

Hi Sandip,
It fetches and populates values from SAPLOgon.ini file stored on you machine.
Same file is used to show system list in SAPGUI logon pad.
So, If you are getting system on logon pad then it should show same in the dropdown.
One more point:
Is you backed system uses message server to rought to hte server? If so, then provide Host or IP of the message server instead oh Application server.
