Adaptive RFC in webdynpro

Hi, I developed a custom application in webdynpro and made it to work and in the mean time the sneak preview license expired. I have reinstalled the sneak preview but cannot get the application to work. I had saved the old application in my hard drive and the cannot reimport the model. Any help in this regard is highly appreciated.
Best regards,
Srini.

I found one problem was missing object in the SAP system. Once I got that in place I was able to make the application work. I still have a problem with the Adaptive RFC import. This is the error I get.
I get this exception in a pop up.
"An internal error has occured. See error log for more details. "
Plug in Name - Web Dynpro Model Editor Services
Plugin Id    - com.sap.ide.webdynpro.service.modeleditor
Class - com.sap.ide.webdynpro.modeleditor.wizards.model.
        creation.ModelDialog

          exception trace.
Exception - org.eclipse.swt.SWTException: Failed to
            execute runnable
            (Java.lang.NullPointerException)
Where can I see more information? what is possiblit=y wrong.
Also I cannot connect to SAP system from the IDE. So I am missing something. But I could run the old application that accesses SAP without problem.
Any help in this regard is highly appreciated.

Why we call adaptive RFC in webdynpro java..

Hi,
I want to know why we call adaptive RFC connection in webdynpro java whenever we import new rfc in our java web dynpro project. why name ADAPTIVE RFC is used
if we make any structure changes in the model which we imported in web dynpro project , like adding a new field, or changing the length/datatype of the existing field, then we always have to reimport the model in our webdynpro project so why adaptive name used. wats especial in the word ADAPTIVE RFC

Issue with adaptive RFC model - BAPI

Hello,
I created a simple web dynpro application (as a DC project in NWDS) which is using a bapi in an adaptive RFC model. I based my developments on the official tutorial from SAP and followed each and every step.
The first view shows a single field and an action button to trigger the bapi call. Based on the value entered (employee number), the other view should display a list of data (addresses).
The problem is that after I press the action button, it doesn't make it to the next view. The animated web dynpro icon shows up briefly but the page stays on the first view.
I've monitored user activity on the back-end (SM04) and noticed some activity for my user after the button is pressed so I assume, there is no connection issue.
Any help to solve that issue will be greatly appreciated!
Thanks,
Laurent

Problem in displaying a field in webdynpro using Adaptive RFC model

HI,
I created a webdynpro application using adaptive RFC model and i have a problem in displaying one of the output fields.
When i execute the function module it is giving the exact value for my output field in this case telephone number (of type STEXT which is char with length 40).But when i am trying to display that telephone number in webdynpro application it is taking only first 4 digits.
i deleted the model and recreated it still it doesnot work.
please let me know how to resolve it.
points will be awarded for sure
Bala

Hi Bala,
Whenever you reimport the model server restart is necessary otherwise the changes will not get reflected. You will get an error when you deploy the application.There is no go around except restarting the server as the meta data gets cached in the server as long as the server is runnig.So, Once you restart the server the cache will be cleared.
Check once again whether you are fetching data from correct BAPI field. Still problem persist try debugging.

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 creating adaptive RFC model

Dear All,
I am trying to create Adaptive RFC model by which i can fetch data from R/3 trough BAPI and display on the webDynpro UI.
I am getting error
Exception: org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.ExceptionInInitializerError: JCO.classInitialize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'

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

Adaptive RFC model connectivity to SAP R/3 4.6 B

We are developing a new webdynpro application which uses the backend R/3 version is 4.6B using Adaptive RFC model.
We are able to connect to Web As systems without any issues but getting error messages while creating the Adaptive RFC model to R/3 4.6 B system as backend.
Appreicate your help.

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

Reg: Calling RFC in webdynpro

Hi,
I am supporting some webdynpro application. In the application we are connecting to R3 systems using RFC. But in my application the developer had created different models for each Bapi instead of dumping them into one model. I just wanted to know the logic behind that. Is it just logical seperation or there is any performance considerations.
Thanks in advance.

Hi,
I Just can say, in some of the documents that I have founded in SDN about Web dynpro best practices,
the recommendatios is "Put as many RFCs in a single Adaptive RFC model as possible".
Take a look in the followinf presentation page 41
http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/604ddc2f-ec9c-2b10-1682-be37e1c62dee&overridelayout=true

Looking for a beginner guide - Adaptive RFC call BAPI in Web Dynpro Java

Hi,
im new in SAP Developeing. I developed some basic web Dynpro applications (after some tutorials) and they are all working.
Now i want to build an Web Dynpro application with an adaptive RFC Model.
I already imported the adaptive RFC Modell with a function Model (BAPI Z_...) from the R3 System successfully.
But if i deploy the application i will get following error:

........Looks like a have a Problem with JCO.
Is there a good guide, which explains the Basic steps in developeing Web dynpro applications and BAPI ?!

thank you guys for all the answers.I have to read all the documentations.
to my szenario:
I installed on my notebook the Trial Versions of:
SAP NetWeaver Application Server 7.00/Java AS 7.00
SAP NetWeaver Developer Studio Version: 7.0.14
All my basic Web Dynpro Applications in Java are running (even with Adobe Interactive Forms) on the local NetWeaver Trail- Web AS Trail perfectly.
Now i want to connect per RFC to another SAPERP Server, which is in the intranet.
I did the whole RFC tutorial with the flights -
http://help.sap.com/saphelp_nw04/helpdata/en/c3/76b45d9688e04abe1a1070410ddc1e/content.htm (also with the JCO codeing etc)
so my web dynpro application should work.
I think I have to configure - like ramesh said something on the NetWeaver Trail.
So what do i need and configure excactly on my Netweaver Trial to work with RFC - to call the BAPIS in the other System?
- SLD ? JCO ?
If i over Web Dynpro - Content Administrator - >
it says "Connection to System Landscape Directory (SLD) could not be opended successfully." and all the buttons
create Jco destinations etc. are greyed out.
I didn´t configured the SLD and JCO in the Netweaver yet.

How to set the tables parameter to a BAPI using adaptive RFC model

Hi,
I have a BAPI ZBAPI that has a tables parameter ZPernr of type ZTable with two elements pernr and name.
I used adaptive RFC model and created model classes for the BAPI.
My question how do i set list of pernr and name to the tables parameter in the webdynpro for java.
I have the following methods available
ZBAPI input = new ZBAPI();
1.ZTable table = new ZTable();
table.setPernr(pernr);
table.setname(name);
input.addZPernr(table);
how do i set the table parameter for multiple pernr and name
2.
add all the pernr and name to list and set that list to input in the following way
input.setZPernr(list) and list of typecom.sap.aii.proxy.framework.core. AbstractList
out of two methods mentioned which one is correct.
Please let me know the solution
Thanks

Hi Bala,
 In your code:
List pernrList = new ArrayList();
pernrList should be declared as the type of class HROBJECT ( The structure name in the model e.g. the node PERFWARN type is Zhrecmfm_002_Perfrat_Warning_Input )
Try this:
HROBJECT pernrList = new HROBJECT();
pernrList.setPernr(pernr);
input.setPernr_List(pernrList);
// call BAPI execute method
If you want to pass list of pernrs, you can pass in alternate way
IPrivate<viewname>.I<nodeame>Node prNode = wdContext.node<node>();
IPrivate<viewname>.I<nodeame>Element prEle;
for (int i = 0; i < table.size(); i++) {
HROBJECT pernrList = new HROBJECT();
pernrList.setPernr(pernr); // Set the pernr from current record
prEle = prNode.create<nodeame>Element(pernrList);
prNode.addElement(prEle);
// call BAPI execute method
Once I execute the BAPI how do i iterate thru second table parameter PERNR_PERFRAT to get pernr and performance rating text
Say your node name is PERNR_PERFRAT
for (int i = 0; i < wdContext.nodePERNR_PERFRAT().size(); i++) {
wdContext.nodePERNR_PERFRAT().getPERNR_PERFRATElementAt(i).getPernr();
wdContext.nodePERNR_PERFRAT().getPERNR_PERFRATElementAt(i).getPerfrat();

Siva

What is adaptive RFC and How to Use it

hi friends
what is the adaptive RFC
what is the use of it
how we can use it
explain me anyone
and send pdf also
thanks
ramu.

Hi,
To give u a brief idea.
rfcs are used to call data from the backend that is R/3.We use the Bapis from the R/3 system which have some pre defined functionality and data is populated in the correspoding ui elements in webdynpro interface.earlier Rfcs were used but now we have adaptive rfcs in which
if there are changes in the backend(R/3 system) such as changes in the datatype,structures,fields would be automatically be refllected in the rfcs and there would be no errors in web dyn pro even if there is a change in the back end
to be more specific folow this link
http://help.sap.com/saphelp_nw70/helpdata/EN/41/38bc8f813719488ddc9d9b21251ec3/frameset.htm
and try out this application
to use the rfcs firstly check out this document for configurations

Problem in import adaptive RFC

Hi,
I am trying to import a simple RFC using Import adaptive RFC model.
There is no problem in the RFC execution, since i have tested it.
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.
Thanks & Regards,
Krish.

Any help would be really appreciated...
