Web Dynpro connecting to ABAP trough RFC

Hello,
I created WebDynpro application using ABAP functions accordingly to relevant tutorial. But i have problems with the last step - which is "Creating the JCO Connections."
I can create and test the connection called "WD_MODELDATA...." but i have problems with "WD_RFC_METADATA....". I truthly say that i cannot locate the source of the problem.
If i create WD_RFC... as (Application Data -> Single server) it creates and the test results OK, but later on when running the application i get an exception saying that i have not defined the connection as an MsgServerConnection in CIM. When i try to create is as Dictionary Meta ... i get errors while creating it.
!There is an interesting symptome on step 4.2 in "Create
!new JCO destination" wizard - when I select a Message
!Server the "System name" and "Logon Group" fields remain
!empty and disabled - isn't it strange ?
And in the end, after i press finish i get a red exclamation icon and a following message :
"Failed to create new JCO client connection WD_RFC_METADATA_DEST: com....WDSystemLandscapeException: Error while obtaining JCO connection: com....WDRuntimeException: Failed to resolve connection parameter for WD_RFC_METADATA_DEST at com...JCOClientConnection.resolveCOnnectionParameter4MsgServerJCODestination(JCOClientConnection.java:598)."
Everything in SLD is configured corectly (at least it seems so).
May the version difference (SLD 6.20 and WAS 6.40) be a problem?
I have WAS SneakPreview patch level 4, my OS is WINXP,SP1.
R/3 server i try to connect to is version 4.6C
Marcin Galczynski

I had the same error with the Sneak preview. I followed all the steps mentioned in the used the SAP NetWeaver '04 Post-Installation Guide to set up SLD on the Sneak preview WebAS installation. You can find this at
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sapportals.km.docs/documents/a1-8-4/sap system landscape directory on sap web as java 6.40.pdf

Last step of ".... web dynpro application accesing ABAP functions" FAILED

Hello!!!
I can't run my app (Example: Creating a web dynpro application accessing ABAP functions).
I will be very grateful if someone tell me what is happening. While I'm developing I can connect to my was 6.20 to see de BAPI and other stuff, to use on my program, but once I deploy the app and try to test it... this is what it drops:

I found at "How to Use the Web Dynpro Content Administrator.pdf" a good place to look for my mistake. But a big question appeared:
Once I get in the Web Dynpro Content Administrator and found my deplyed app I found this two JCo:
WD_MODELDATA_DEST
WD_RFC_METADATA_DEST
Witch status was a little grey diamond, or something like that. ¿Can somebody tell me what is happening with this Jco?
The page 27 of the pdf mentioned before, was different in my IDE SAP Developer Studio, the only option, by default, that give me was to choose between WD_MODELDATA_DEST and
WD_RFC_METADATA_DEST. I have two fields that must be fill to pass to the next dialog box or finished the creation RFC model.
Thanks a lot !!!

Hi,
In NWDS, you should have defined your own JCo destinations when creating your model. For example:
- WD_<yourApp>_MODELDATA_DEST
- WD_<yourApp>_RFC_METADATA_DEST
Then in the Web Dynpro Content Administrator, you must create them, ie specify connection types, connection parameters...
For this, choose the button Maintain JCo Destinations, find the connetions you've created in NWDS and click the button Create. Just follow the steps of the wizard, and you're done!

Nicolas

Error - Creating a Web Dynpro Application Accessing ABAP Functions

Dear All,
we are trying to implement a web dynpro application with accessing ABAP functions.
Previous tasks:
-     insert the ABAP system into the SLD from the NWDI System (Transaction RZ70; the ABAP system is correctly insert into the SLD => technical systems)
-     equipped the JCO connections with the web dynpro content manager (ping and test = OK)
Its the standard tutorial out of the SDN called Creating a Web Dynpro Application Accessing ABAP Functions.
Some hints:
-     There are no errors after the implementation and the rebuild of the project in the NWDS
-     The auto deployment works fine to the development runtime system. The application is shown in the Web Dynpro content manager
-     The In the build log I found these entries:

-     Im able to start the application out of the Web Dynpro content manager with run => only the user interface is displayed without any functionality
-     The normal start over the NWDS fails => error text

There two different URLs in use.
Start via NWDS:
http://frasapp562:50000/webdynpro/dispatcher/J08_Flugdat_Daventdcflight~xxx.com/FlightListApp
Start via web dynpro content manager:
http://frasapp562:50000/webdynpro/dispatcher/xxx.com/aventdc~flight/FlightListApp
For test purposes, we started the BAPI (BAPI_Flight_Getlist) on the ABAP system directly. It works.
Any ideas about the system behaviours (different URLs and missing functionality)?
Thanks a lot in advanced!

Web Dynpro Application Accessing ABAP Functions

I wrote the example application for Web Dynpro Application Accessing ABAP Functions, as described in the tutorials for NWDS. But when I run, it only show me a blank blue page nothing else, how to fix this issue?
Thanks,
Jawed Ali

Hi Jawed,
Again, I'll insist you to please check if your view is embeded in the Window.
write some output message in the view to ensure that not only gui's, even the messages in the view are not coming.
if there is another issue, Please share with us.
Thank & Regards,

EXCEL Web Query - load into SAP via Web dynpro or standard ABAP

Hi everybody
I was wondering if you can run an EXCEL WEB Query from abap and then upload the data retrieved from the web into SAP using either a web dynpro application or standard SAP.
For standard ABAP one could probably run the EXCEL web query by executing some code such as
call method cl_gui_frontend_services=>execute
exporting
document = 'your excel web query file'.
You could then save the data and using GUI_UPLOAD get it into sap.
I'd really like to do it via a web dynpro application.
Any ideas anyone.
For guys who've never used EXCEL web queries --quite easy.
Open EXCEL
go to Import External Data
Choose New web query
Enter URL of where you want to retrieve your data from such as YAHOO finance etc.
For example to get the components of the Dow Jones Composite Index (^DJA) use this url
http://finance.yahoo.com/q/cp?s=%5EDJA
click the yellow arrow on the table data you want to import. The arrow will turn Green and press IMPORT
Then enter the cell number where you want to start importing data
Hey presto you've got your data from the web.
Cheers
jimbo

when you create a new webquery, in the properties, you can set when the page should refresh (data fetch to happen), you can set that to refresh at file open.
then you can use either OLE or gui_upload to upload the excel to read the data.
have couple of question:
why do you want to choose excel webquery ?=> is it because the ability to get unstructured data from the web?
what sort of data you are trying to read from the web?=> most of data centric sites (forex, stock quotes) will have either RSS feeds or some web APIs to get data which can be easily consumed by ABAP

Web Dynpro Callable Object : use of RFCs

Hi All,
I've to create a callable object using Web dynpro.
In this web dynpro to display a table data populated by calling RFC and we need to select one row of the table and sent it as output parameter.
My question is how we gonna set the getDescription Method in this case for creating the Callable Object?
How we define the execute Method in the Interface Controller.
Where I should bind the Model to Controller (Component Controller / Interface Controller)
Can someone explain how we gonna use RFC in Web dynpro while calling it as Callable Object.
Thanks
Srikant

Hi,
You need to have the SCs for local development of Web Dynpro callable object.
Refer the following documents for more details:

External facing Web Dynpro - Java or ABAP

We are planning a external facing web site delivering dealer information from SAP backend. We would like to use Web Dynpro to build the site since that give us easy access to SAP data. But we are not sure if Web Dynpro is suited for such use.
Can anyone share their experience on delivering Web Dynpro application, Java or ABAP, to external facing web site? Is it required to also have a external facing portal to authenticate users? Can we apply the external facing portal scenario when delivering web dynpro iView?
Thanks
Ben

Hi Ben Liang ,
You can simulate the requirement both in webdynpro java and webdynpro abap. For botht he case an external facing portal to authenticate users is required

ESS - Web Dynpro Java or ABAP

Could anyone pls tell me about the Web dynpro part of ESS/MSS. In which language it's written, i mean in Java or ABAP. Pls send me some links for the starter to learn ESS/MSS.
Thanks,

Hi Experts
We have a customer which are currently running a SAP NW Portal (7.0) and are
Currently upgrading to ECC. 6.0 enh.3. They would very much like to use the org.plan iview in the current ESS business package to the portal, based on Java. But we have heard that the ESS business package should be converted to web dynpro for ABAP in the future releases. Does that also applies to the current org.plan Iview?
Should we advise the customer to wait until the business package is available in Web Dynpro for ABAP, or will the org. plan Iview stay in Java?
Thank you for taking your time..
Regards CC

RFC/BAPI Call (ABAP Web Dynpro)- DYNPRO_SEND_IN_BACKGROUND

Hi all,
I'm developing an ABAP Web Dynpro application which utilise a RFC enabled function module. When I tried to execute the function module through the browser it terminated with an abap dump. I checked ST22 and found the following dump: 'DYNPRO_SEND_IN_BACKGROUND'. However when I tried executing it using SE37, the function module works fine.
Any ideas?
Ricky

Hello Ricky,
to my guts feeling that should be fine, but I have never used call dialog in such a scenario. If I were in your shoes I would try to break down the problem:
- Is it of general nature?
- Is it specific to this dialog?
To distinquish that I would write the most basic dialog and use it the same way as the target one. If this fails too, using FuBa´s with call dialog seems to be not possible => try to avoid that situation. If the test succeeds, well the hunt for the needle in the haystack is open.
Good Luck
Klaus

Connecting to R/3 System through Java Web Dynpro forms.

Hi,
I have a requirement in which I have to send data to R/3
from Java Web Dynpro screens.
I will design the Java Web Dynpro screens and write a RFC Model.
I will write a RFC in se37 which will connect to the RFC Model.
Before creating the RFC in se37, I will create ztables in se11.
I will write a ABAP Report to see that all data enters the ztables.
I need some guidance with regard to this.
Do, the RFC Model have the access of the ECC(R/3) System.
What are tasks to be told the Basis guy so, that RFC being called from through Java Web Dynpro?
Please provide me some documents with regards to this scenario.

The steps you provided is clear enough to connect to a R/3 system through the WD forms.
On creating the model you need to give two inputs such as
logical system name for model instance
logical system name for RFC metadata
there will be 2 default values, also you can create your own JCOs in the <servername>:<port>/devinf of the server or u can ask your basis team also.
Before creating the JCO , the SLD (System Landscape Directory) needs to be configures, that your basis team will know.
other than that once you create the functional module in se37 make it RFC enabled , and once you import the RFC model , you can give your ECC system user name and password and search for RFC you have created from the list of RFC.

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:
com.sap.tc.webdynpro.services.exceptions.TypeNotFoundException: type extern:mypackages.com.types.BapiModel:mypackages.com.types.Zmbs_Bapi_Dispo_Orderdata could not be loaded: com.sap.dictionary.runtime.DdException: TypeBroker failed to access SLD: Error while obtaining JCO connection.

........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.

J2ee_admin is used as the user when RFCs are run on the web dynpro appln.

I have created a web dynpro application which has some RFCs on the model.
View is an adobe form which send the data to the RFC and upon submit executes the RFC to create an item in SAP (xRPM).
When the RFC is run, user is taken as J2EE_ADMIN even when authentication is enabled on the application and
a different user is used.
Is it due to the adobe form or the web dynpro application?
Is there anyway we can change this default and capture the user logged in accordingly.
Versions used:
NWDS 7.0
SAP NW 2004s SP 15
Adobe Live cycle designer 7.0
Thank you,
Vasu

Hi Subramanya,
Please check the user Id, what your given for JCO connection (MODELDATA & METADATA).
