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.

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

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

Can not create an new rfc model, NW DevStudio SP11

Hi,
I have installed the NetWeaver Developer Studio SP11
and now if I create a ref model I get this exception:
org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.NoClassDefFoundError: com/sap/tc/logging/LogController)

Fran,
it's in SAP Service Marketplace at http://service.sap.com/notes. Some Notes are replicated to SDN, unfortunately not all of them. What's missing are most of the Notes under component BC-*, which is the one for Web AS.
In case you can't get into the Marketplace, here's the text:
SAP Note No. 832994
Short text          NoClassDefFoundError during adaptive RFC model
import
Component           BC-DWB-WD-JAV
                    Web Dynpro Tools - Java
Long text
Symptom
You import an adaptive RFC model with Web Dynpro tools, and the system
issues the following error message:
org.eclipse.swt.SWTException: Failed to execute runnable
(java.lang.NoClassDefFoundError: com/sap/tc/logging/LogController)
Other terms
Reason and Prerequisites
You use SAP NetWeaver Developer Studio with Support Package 11.
Solution
The Eclipse installation directory contains a "plugins" folder. This
folder, in turn, contains the "com.sap.mdi" plug-in folder. Open the
"plugin.xml" file located in the relevant plug-in directory in an
editor.
Insert the following line in the list of required plug-ins:
<import plugin="com.tssap.sap.libs.logging" />
The contents should look as described below. The change becomes
effective once you have restarted the IDE.
<?xml version="1.0" encoding="utf-8"?>
<plugin id="com.sap.mdi" name="%pluginName" version="2.0.0"

Import RFC Model

All,
I'm using Sneak preview full java version. When I try to call SAP Function module from webdynpro Java via RFC Model, it's asking me to specify the SAP Server detail logon information.
Can anyone help me what information i should give becos im using Sneak preview Java version...
Thanks..

Hi Bharathi
If u want to import Adaptive RFC Models from ABAP backend u have two ways for importing the model
1) single server : where u need to specify ABAP system creditials such as Application server name,client,system number for ABAP system available in ur Local Area Network
2) Load Balancing : Here DropDown List is automatically populated with list of ABAP servers which are defined in ur SAP LOGON PAD . Actually NWDS picks up names of these servers from <b>saplogon.ini</b> file which stores all ABAP servers defined in ur SAP LOGON PAD
so if u have entry for the required ABAP backend in ur SAP LOGON PAD then u can go for Load Balancing method in which most of the entries will be automatically populated from saplogon.ini file
If u donot have SAP LOGON PAD or saplogon.ini file doesnot have entry for the ABAP server then u should go for single server mode for Importing RFC models
Hope u Got the difference between the two methods now

Why We Call Adpative RFC MODEL?

Hi ,
Why We Call Adaptive RFC MODEL?
What is RFM?

Hi Subbarao,
The Adaptive Remote Function Call (Adaptive RFC) is a technology that enables the Web Dynpro application developer to use the business functions encapsulated in Business APIs (BAPIs) even after a structure modification, without having to provide the new data using a second back end or a new structure with subsequent regeneration of the proxies.
This new RFC model shows adaptive behavior. This means that the RFC proxies do not use the original design time structure definition at runtime. Instead, this Web Dynpro model automatically adapts the data of the structure passed in the Java proxy generation to the current data that is, a structure definition in the back-end system that may have been modified
For more info go through this link..
[Adaptive RFC|http://help.sap.com/saphelp_nw70/helpdata/en/6a/11f1f29526944e8580c5e59333d96d/frameset.htm]
Importing RFC's
__http://help.sap.com/saphelp_nw70/helpdata/en/6a/11f1f29526944e8580c5e59333d96d/frameset.htm__
RFM - stands for Remote-enabled Function Modules, amd you can learn more about it from
http://help.sap.com/saphelpnw70/helpdata/en/22/0427c0488911d189490000e829fbbd/frameset.htm_
Difference between BAPI and RFM --
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects.
You create business objects and those are then registered in your BOR (Business Object Repository)
which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA.
In this case u only specify the business object and its method from external system
in BAPI there is no direct system call. while RFC are direct system call.
Hope this helps,

We have an existing application with few custom BAPIs are called. However we added few fields added to the custom BAPI. We could not figure out how to bring the new fields show up in used Model and context.
Any Help greatly appreciated.
Thanks.

Hi ,
The following link help you.
Importing Models Using the Search Console - Developing Java Web Dynpro Applications - SAP Library
SAP Library - Development Manual
Now to call the FM you have to follow the steps:
1)In NWDS click on models->then right click it select import Adaptive RFC model
2)Here gave the name of the Model , package etc and the names of the JCo Destinations tht will be needed to call from R/3.
3)Give the Information abt the R/3 Host and username password of the R/3.Press Next
4)Now search for the Bapi you want to Use. Select it Press Next
5) press Finish. You have imported a Bapi from R/3.
Now you can play around with it according to your requirement..
You need to create the Context, Views to show the Data of the Bapi.
Hope this helps you out.
Thanks & Regards,

Problem in import adaptive RFC

Hi,

Problem is output is not getting displayed. The output field is blank.
Note:
RFC while importing, is in warning state(yellow triangle). But no error or warning in back-end.
Please let me know what is the mistake.

Export of RFC Model to Java Project DC ?

I've got a Web Dynpro project where I used the Wizard to import an RFC Model. Now my client has this requirement that all Web Dynpro Models should be based on Command Beans that reside inside their own separate java DCs.
My question : is it possible to export my RFC Models packages and folders (along with my other Model classes) to a java DC project - to be later reimported back into the Web Dynpro project ?
Thanks for any input on this

Hi Romeo,
To answer your question first there is no standard supported way in which you could expose RFC Model in seperate Java DCs.
If the question is just to have the classes (proxy) created for RFC to connect to r/3 and get the data then you could use SAP Enterprise Connector, but i would not recommand that as you loose out the complete declarative way of using RFC and so called CMI Model support for Web Dynpro.
Secondly if RFC Model which you are planning to expose as part of java dc has to be consumed in Web Dynpro then i do not understand the need why some one will require to expose the RFC Model in Java DC and the inherit concept of RFC Model is related to Web Dynpro and not with normal Java DC thus its a matter of choice do you want to use plaiin java classes without Model driven approach or more declarative way as in case of Web Dynpro.
Thanks

Using an Adaptive RFC Model from JSP

I'm trying to use an Adaptive RFC Model I created for use in our Web Dynpros from a Portal Application project. I've created 2 DCs:
1. A Web Dynpro DC, only containing the imported Adaptive RFC Model. The model has been added to the public parts.
2. A Portal Application DC, with the model DC added as a DC usage (along with the other required DCs)
Now, everything appears to work from inside NWDS. The dot operator works while editing my JSPDynPage class, and everything builds fine, but when I deploy and test in the portal, I get "package not found" errors on the actual JSP. I assume this is because the JSP is compiled at run-time. How do I expose these classes to the JSP compiler?
It's seems like using the same method to call BAPIs in Web Dynpros and Java iViews would be a good practice following SAP's "reusable code" policy, so there must be a way to do it...

Jonathan,
Adaptive RFC Model works correctly only when running inside WebDynpro container. JSP runs outside container (in regular J2EE WebApplication container).
The error you receive is due to missing run-time references to container classes.
Actually, what you are trying to do is dead end, sorry.
Use SAP Enterprise Connector instead of Adaptive RFC model. Generated connector classes works from any environment. Also they are sooo similar to Adaptive RFC that you'll even not mention a difference.

BAPI Name in RFC model

Hi
I imported an RFC model, specifying a BAPI in doing so. I now cannot remember the name of the BAPI and cannot seem to fine where it is specified in the imported model or the content administrator. Can anyone tell me where I might find this info ?
Cheers
Damien

Hi,
You can find all Adaptive RFC names in folder
Drive:\username\digit(0...)\DCs\package\p1\comp name\_comp\bin\p2\p3\p4\p5\p6\mdl
like
BapiName_Input.class
BapiName_Output.class
PS: p1...p6 all are package names which may differ.
