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.

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'

Kindly suggest.

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

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.

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
Bala Duvvuri

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();

Error while creating Adaptive WS model(SP17) using local WSDL file

Hi,
I am trying to create a model with the wizard for adaptive Web Services, without using logical destinations. I have download the file from PI Server. This WSDL file is not registered in UDDI. But when I try to upload my WSDL from local disc I get an error message, which defines in the .log file like this:

Do help me how to reslove this problem.

Did u use "webservice model" or "adaptive webservice model".
Earlier i used with "wenservice model" and it was working fine. Now that with SP17, "WebService model"is depricated and we are forced to use "adaptive webservice model" and it is giving the problem. the detailed error is :

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

Sandip sir,
If u can access the webservice in webdynpro in this server,u can check the webservice in wsnavigator also.If its working on some other server,may be its not deployed properly on the server u r using.
If the service is deployed on the server,it will be available on wsnavigator also.
note: If u can't see the service in wsnavigator,how do u check whether the service is working properly?If there is any other method to check the service,do let me know also,so i can try.

Getting 'File not found' error while using server object model code

Hi,
I am using server object model code to pull list data in a console application. My machine has standalone installation of SP 2010. I am getting error 'File Not Found', however the same operation is working fine with client object model code.
Code I am using:
string strURL=http://servername/sites/sitename;
SPSite siteObj=new SPSite (strURL); //getting error here.
I have already checked the below,
1. Framework being used is 3.5.
2. I have proper access to site.
3. Running visual studio as admin.
Any help is much appreciated.
thanks
Tarique
thanks and regards Tarique Aslam

Hello Tarique ,
Couple of pints need to check:
1. User running the console application needs to have at least read permission to the SharePoint databases
2. Set application by changing the "Platform target:" option on the "Build" to "Any CPU"
Also refer this similar thread:

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

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'

I get the NoClassDef found error next time onwards,
Where do I get the 620.0.1374 version of librfc?
thanx.

Hi Dhrruv,
You can check your SAP R/3 username and password with the BASIS person or Security person.
Once it is confirmed, give the following details:
Host Name : abcdefg.hij.xyz (ie.give the alias of the server )
System Number : 00

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

Adaptive RFC Model - disconnectIfAlive()

Hi,
In my Web Dynpro application, I am using Adaptive RFC model and executing the RFC as below
ZRfc_Test_Input input = new ZRfc_Test_Input();
// set input
input.setParam1("xxx");
input.setParam2("xxx");
input.execute();
My application works fine for couple of days and suddenly I get an error that
"com.sap.tc.webdynpro.modelimpl.dynamicrfc.WDDynamicRFCExecuteException:Could not create JCOClientConnection for logical System: WD_TEST_MODELDATA_DEST - Model: class com.test.TestModel. Please assure that you have configured the RFC connections and/or logical system name properly for this model!"
Our basis guys are unable to figure out why the SLD is misbehaving suddenly. If we restart the SLD, everything will be fine for next couple of days.
I just want to make sure that it is not happening due to my application or due to the way the RFCs are being executed.
After I execute my model, do I have to explicity disconnect the connection using below statement?
input.modelInstance().disconnectIfAlive();
Do I have to do this even when I am using Adaptive RFC model?
Default min and max number of connections are used while creating JCO destinations.
Appreciate your input.
Thanks
Kumar

Hi Siva,
>>> It is always better to close the connection after executing the RFC<<<
Thanks for the response. I am sorry for being adamant, I agree that it would be nice to disconnect but IS IT MANDATORY? If the pool size is increased appropriately, doesn't web dynpro runtime takecare and disconnect the connections after the execution.
In SAP tutorials and help.sap.com (at least the ones I have gone through), it is never mentioned any where that one MUST close the connections EXPLICITLY after the execution. All these days I am under the impression that it is not needed for Adaptive RFC models. I may be wrong.
Could you please confirm if we should close the connections explicity?
Thanks
Kumar
