SRM RFC Model Error in Webdynpro JAVA

Hi All,
When I create a model from Any R/3 RFC in Webdynpro(JAVA) and map the RFC model context to Controller Context then every thing works fine, but when I create model from SRM RFC(Model is created with no problems at all) and map the SRM Model context to Controller Context, then I get below error:
com.sap.tc.webdynpro.services.exceptions.TypeNotFoundException: type com.cnsl.srm.model.types.Bbp_Category_Id could not be loaded: com.sap.dictionary.runtime.DdException: Type com.cnsl.srm.model.types.Bbp_Category_Id does not exist
Is there any thing specific to SRM that we have to do on the Webdynpro(JAVA) side to be able to call the SRM RFC. Kindly suggest me. Also please if you can forward me to forum thread/blog in case there is any.

Error in webdynpro java interactive forms used

hello,
I have followed the installation manual to configure ADS wizzard service which is done successfully. I have also made a webdynpro java project where I use very simple smartform with FirstName and LastName as context variables. But when I run the application I see
java.io.IOException: Cannot connect to http://<server>:50000/inspection.wsil, used user to connect: administrator Check if the valid port is used or the system is not down. HTTP Message : Unable to connect to <server>:50000 - Connection timed out: connect
If I put this wsil URL it works fine. But I don't know if any thing is missing in configuration. I am quite new in smartform need help.
I have also downloaded credtional file from SDN but I am new and need help to setup in NWA if this cause the error.
If any one can recommend me step by step guide would be helpful for me.
Thanks in advance.
NK

Hello Otto,
well I have no such concrete one source to follow and setup ADS services. But some how from sap help portal, and Tutorial on Installing Credentials and Configuring ADS author Amol Gupta, and ADS configuration guide sourced: http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/30a9630b-4f89-2a10-6fab-e311b3ffd9a6
I have also tested the service in the wsnavigator AdobeDocumentServicesTestVi, but got error level 2 with Entity: ConfigurationService Error: Checking for default credential aliases - failed
Here I found creditional error. which I have to configure in NWA, I guess.
I have downloaded creditional from http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/70aa75cc-6ac3-2910-c78c-ade192ec861e
I need help to configure this creditional also.
And If you have some useful guides then please recommend me.

Error while creating a RFC model for WD for Java

Hi,
While trying out the example(TutWD_FlightList_Init.zip) for model programming in the NDS,I got the following error when I try to create a model:
Plugin Name Web Dynpro Model Editor Services
Plugin Id com.sap.ide.webdynpro.service.modeleditor
Class com.sap.ide.webdynpro.modeleditor.wizards.model.creation.ModelDialog
Method nextPressed
Message Internal error - see detail information in exception trace
Exception org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.NoClassDefFoundError)
Can anybody help?Is there any place in NDS to see the detailed error message?
thanx in advance,
Bhupesh

I modified the xml file as described in the forum.But the error persists.
One interesting thing is:
When I create model after restarting the NDS,I get the following error:
org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.ExceptionInInitializerError: JCO.classInitialize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'
JCO.nativeInit(): Could not initialize dynamic link library librfc. Found version "620.0.1237" but required at least version "620.0.1374".)
I get the NoClassDef found error next time onwards,
Where do I get the 620.0.1374 version of librfc?
thanx.

Hi Murali,
    Looks like the related RFC from backend has not been transported to the production server. Please check if the RFC is transported. You can check your named transport requests in SE09 T.code in your quality.
Hope it helps.

Model Problem In webdynpro java

Hi all,
I am facing a differnent problem with model classes in my webdynpro application.
I have a componenet where in i am using standard BAPIs.The problem here is i am getting the latest data from the bapi only when the application is loded first.
If i add a new record and want to know the size of output node it is not giving the latest one.It is showing the size it has when the application is loded,But in the backend it is getting updated everytime.
What might me the problem for this??Is it that the model proxy classes that are loded when the application is loded is not getting refreshed??
Edited by: chandrashekar chandrashekar on Dec 10, 2008 7:30 AM

Hi,
This is the code i am using...
My problem in brief is if i try to add a record it is getting updated in SAP but if i try to display the output node it is giving the size it has when the application is loded.
If i restart the application it is giving the updated sise of the output node
Bapi_Class_Getdetail_Input inputGetDetail = null;
inputGetDetail = new Bapi_Class_Getdetail_Input();
wdContext.nodeBapi_Class_Getdetail_Input().bind(inputGetDetail);
inputGetDetail.setClassnum(className);
inputGetDetail.setClasstype("300");
     try
          executeBapi_Class_GetDetail();
     catch(WDDynamicRFCExecuteException ex)
          return false;

Webdynpro ABAP or Webdynpro Java?

Hello experts.
I want to learn to develop WebDynpro's
Do you which of the two tools do you recommend? webdynpro java or webdynpro abap.
Greetings

Hi Lupe ,
Although both technologies have same functionalities but even then they are not identical.
Following are some of the differences:
Language :- First difference is the programming language used as the names Webdynpro ABAP and Webdynpro JAVA reflect. In ABAP Webdynpro, along with ABAP coding, RFCu2019s are also supported via Service call. Unlike Webdynpro ABAP, we cannot do ABAP coding in Webdynpro JAVA. Instead RFCu2019s and Web services are created and used in it to serve this purpose. In addition to Web services and adaptive RFC, Java Beans is another model supported by Webdynpro JAVA.
Design Time Environment :- Webdynpro ABAP requires ABAP Workbench (SE80) while SAP Netweaver Developer Studio is necessary for designing Webdynpro JAVA applications. So, additional installation is required. This studio reduces the development effort and utilizes some visual tools for creating components which can be reused.
Storage :- Applications developed using Webdynpro ABAP are stored centrally in ABAP server whereas in case of Webdynpro JAVA, the code remains on the client machine that is developed using a tool called Netweaver Developer studio. So, due to the powerful version control system of Webdynpro ABAP, the load removes from the development machine which is not possible in case of Webdynpro JAVA.
Skills Required :- For Webdynpro ABAP, a developer should have knowledge of ABAP programming, Development tools, Database concepts, ABAP Objects. However, Webdynpro JAVA requires skill set comprising java programming, java development tools and object-oriented concept.
Performance:- Large scale applications that involve large number of web users canu2019t work well on ABAP server. So, for robust and scalable applications, Webdynpro JAVA is preferred because of powerful J2EE server as proved by Sun Microsystems. However, small-scale or applications involving small or medium users can go well with Webdynpro ABAP. Thus, performance varies depending on the number of web users and one can choose ABAP or JAVA accordingly.
So the decession is that its totaly based on your available skillsets and your scenario to be implemented.
Thanks & Regards,
Monishankar C

Call to RFC model

I need to call the method execute() of RFC model in my webdynpro inside a task.
Input Parameters of abapi are in the context of webdyinpro that is mapped to BPM context. The problem is that when i run abapi inside wdDoInit() method of webdynpro , the context of webdynpro not yet initialized.
What webdynpro method i must use to run my abapi???

The issue is that the usage of embedded components comes with a few caveats you need to be aware of. E.g. the following:
Using Web Dynpro component usages at runtime, data is set to Web Dynpro context elements at a certain point of time in the Web Dynpro componentu2019s lifecycle. Consequently data processing of data that is set from an outside (loader) Web Dynpro component, for example from the process desk, should be done afterwards. Referring to the hook methods of a Web Dynpro component, this is after the component controlleru2019s wdDoInit() method.
Source: http://help.sap.com/saphelp_nwce711/helpdata/en/48/cae1791e774da5e10000000a421937/frameset.htm
Hence, the WD context has not yet been injected from the outside in the wdDoInit() call.

Error while importing a Adaptive RFC Model

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.

Some issues when consuming RFC2 model using WebDynpro Java CE 7.11

Hi Experts ,
I'm using Web Dynpro for Java to develop our project. I have issues when I use RFC 2 model to call BAPI function . I already create the RFC 2 model successfully to call one PO BAPI function --- BAPI_PO_GETDETAIL. The whole project build and deploy successfully. At run time, it will call the execute() function of the model object. It also works fine and get the return values.
I just want to get two return objects : PO_Items and PO_Item_Schedules .
So far, every thing works fine. But when I want to iterate the PO_Items node and get each property value of current element, the following error occurs :

I use the same way to iterate PO_Item_Schedules element. It also works fine. Therefore, I don't know why this error happens?

Hi Experts,
I continue this thread because it seems that I have the same problem as the one asked by Wester Wei.
I'm developping an application on NWDS using CE 7.11 (I've learned RFC2 with the tutorial [here|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f0b102ea-efff-2b10-b3aa-d9e84a2c6bb6?overridelayout=true] ). The problem seems to come from the RFC2 Model, but I just import it (and I can't modify it afterwards, because it is a read-only model).
So, you advise to "declare one boolean variable and assign Prnt_Price to that variable." or to "Explicity convert boolean to string.", I think you are right, but I don't know how to do that in my app (in the component controller ?). Therefore, the attribute that occurs the problem is in the context outputs, to I don't know I will be able to affect it before calling the BAPI.
Could you tell me how to fix this problem without modifying the model (because it's read-only) ?
Thank you for advance,
Louis

Error while using Adaptive RFC model

I am using adaptive RFC model to consume a function module from BI system. The function module expects a Boolean input. While executing the function module we need to give u2018Xu2019 for that input. When I consumed the function module in the webynpro java project , used it and give the input as u2018trueu2019 on runnig the application it gives the following error: u201Ccom.sap.conn.jco.ConversionException: (122) JCO_ERROR_CONVERSION: Cannot convert a value from type java.lang.Object to CHAR at field I_READ_ATTRu201D
There is corresponding dictionary type created called u2018BOOLE_Du2019 but I could not access the dictionary type in the controller java file.
Is there a way to rectify the same or any workaround condition?
With regards,
Sougato.

Hi saurabh,
I need to give the value from webdynpro. Hers is the sample code.
rssem_Cha_Values_Get_Input.setI_Read_Attr();
// It expects a boolean value but if i pass a value to the method the obove error is show.
Where as there is a simple type "Boole_d" generated when i consumed the RFC in the webdynpro.
but i couldn't access this simple type in the code.
With regards,
Sougato.
