Calling RFC from JSP : development component

Hi everyone,
I created JSP that call RFC from SAP/R3.
I have problem with the DestinationService.
Without DCs, it worked very good.
But since I created a DC for my JSP project, I have exception at run time regarding
the java.lang.NoClassDefFoundError: com/sap/security/core/server/destinations/api/DestinationService.
Eventhough I add the specific jar, I get an excpetion.
Thanks for the help.
David

Go to the application-j2ee-engine.xml file and add following reference:
     <reference
          reference-type="weak">
          <reference-target
               provider-name="sap.com"
               target-type="interface">tcsecdestinations~interface</reference-target>
     </reference>

Calling RFC from custom connector

Hi,
I am developing a custom connector for UWL to get tasks from 3rd party system.
I need to call a RFC from backend SAP system to complete Input data for this 3rd party provider.
I assume that I have to make an RFC call from getItems() method of connector.
Any idea how to call a RFC from UWL custom connector code?
Please help.
Thanks & Regards,
Amey

Hello Karri,
Yes, I am aware of two ways of calling RFCs from Java code.
Normally, I use following approach to call RFCs from my other Portal Components (JSPDynpages): -
IPortalComponentRequest request = (IPortalComponentRequest) this.getRequest();
IPortalComponentContext myContext = request.getComponentContext();
IPortalComponentProfile myProfile = myContext.getProfile();
String sapSystem = myProfile.getProperty("SystemIdentifier");
ISystemLandscapeWrapper landscapeWrapper = (ISystemLandscapeWrapper) UMFactory.getSystemLandscapeWrappers().get(0);
ISystemLandscapeObject systemLandscapeObject = landscapeWrapper.getSystemByAlias(sapSystem);
IJCOClientService clientService = (IJCOClientService) PortalRuntime.
getRuntimeResources().getService(JCO_CLIENT);
request.getNode().putValue(LOCALE_NODE_KEY, Locale.ENGLISH);
IJCOClientPoolEntry poolEntry = clientService.getJCOClientPoolEntry(sapSystem,request);
JCO.Client client = poolEntry.getJCOClient();
client.connect();
IRepository repository = JCO.createRepository("repository", client);
IFunctionTemplate functionTemplate = repository.getFunctionTemplate(Z_BAPI_EMP_GBU_GET);
JCO.Function function = new JCO.Function(functionTemplate);
JCO.ParameterList importList = function.getImportParameterList();
importList.setValue("US", "OBJTYP");
importList.setValue(request.getUser().getUniqueName(), "USRID");
client.execute(function);
JCO.ParameterList outputList = function.getExportParameterList();
gbuCountryBean.setGbu(outputList.getString("GBU"));
gbuCountryBean.setCountry(outputList.getString("COUNTRYCODE"));
gbuCountryBean.setPersArea(outputList.getString("PERS_AREA"));
gbuCountryBean.setCompanyCode(outputList.getString("COMPANYCODE"));
When I tried implementing same in UWL custom connector, I am not able to get instance of 'request' object.
Any hints/ideas on this?
Hence as an temporary alternative, I wrote following to successfully execute RFC.
mConnection = JCO.createClient(sapclient, sapuser,
sappassword, "EN", saphost, sapsysnumber);
mConnection.connect();
mRepository = new JCO.Repository("GetLeaveRequestFlag", mConnection );
IFunctionTemplate ftemplate = mRepository.getFunctionTemplate(Z_BAPI_CHECK_LR_TO_APPROVE);
myFunction = new JCO.Function(ftemplate);
JCO.Field OBJECT_TYPE = myFunction.getImportParameterList().getField("OBJECT_TYPE");
OBJECT_TYPE.setValue("US");
JCO.Field USERID = myFunction.getImportParameterList().getField("USERID");
OBJECT_TYPE.setValue(p_userID);
mConnection.execute(myFunction);
JCO.Field leaveRequestFlag = myFunction.getExportParameterList().getField("FLAG_LEAVE_REQUEST_RECORD");
mConnection.disconnect();
But only catch here is that I need to create & maintain SAP logon credentials for a particular user manually.
It is not possible to single sign on connector user into SAP system (like its done above).
Any thoughts on this?
Thanks & Regards,
Amey

Call RFC from DELPHI Windows Services Program

Hi all,
Are there any way to call RFC from DELPHI Windows Services Program?
Best regards.
Munur EBCIOGLU

Hi again Bhagat,
1. Yes, it's included on 7.4 ABAP Stack (SAP NetWeaver 7.4 SP8 - Optimized for SAP HANA, Cloud and Mobile - Service Release 2 available now!). In a recent customer, SAP licences GW by user but there are other license model like session licensing: https://store.sap.com/sap/cp/ui/resources/store/html/SolutionDetails.html?pid=0000009470&catID=&pcntry=US&sap-language=EN&_cp_id=id-1385059687642-0
2. You could install as an AddOn on your 7.3 system, there are many options depending on your desired infrastructure: SAP Gateway deployment options in a nutshell For example our customer have deployed Central Hub Gateway in a standalone stack ABAP to act as an standalone oData bridge between ABAP/nonAbap systems.
3. You could deploy SAPUI5 apps in 7.x, Java Web Servers or HTTP Web Servers. You must consider your SSO scenario:
- SSO Logon Tickets. You will need to configurate SSO Logon Tickets between SAP NW Portal & SAP NW Gateway & your backend (ECC, etc). In order to pass SAP session cookie you will need setup SAP Web Dispacther and access portal & gateway throught SAP WD with the same domain.
- SAML2 Tickets. This scenario lets you provide portal & gateway on different domains enabling SSO. You could configure SAP NW Portal as an Identity Provider and other systems must trust SAP Portal as IdP.

Thanks for ur reply

Hi,
Although I have not worked with Powerbuilder, I am sure if you have a certain level of proficiency with it, you will be able to code your logic that will call your wrappers written in VB/C/.NET etc. Check out the wonderful weblog by Thomas Jung on integrating ActiveX controls with ABAP Control Framework at https://www.sdn.sap.com/sdn/weblogs.sdn?blog=/pub/wlg/995.

Calling RFCs from Web through XI

We have used SAP.NET connector in the past to call RFCs from ASP.NET pages from our public website. We have now decided to use XI as the enterprise integration engine going forward.I am interested to know whether anybody has used XI to call RFCs from ASP.NET webpages. I do know that the XI to SAP calls would be made through RFC adapter.Will the communication from ASP.NET page to XI be thourgh the HTTP adapter ? or is there any other smarter way. Can somebody point me to sample code for the calls through http adapter or a how to guide?
cheers
Ramesh

Hi
U have scenario like this ASP.NET->XI->RFC, that means u will send a value from the ASP.NET page to RFC thru XI and then this RFC will give result which will come to ASP.NET frontend.
For this go thru this blog it will help u to understand how to communicate from ASP.NET to XI

Calling RFC from view/component controller

I've got a model node in the component controller's context which is mapped to a node in a view controller. Now, when binding the model's input node with an array and executing the RFC from within an event handler in the view controller, everything goes just fine.
Now, I want to put this functionality in the component controller, so I created a method there, copied the code and call it from the view controller's event handler. When the RFC is called, the input table always contains just 1 element, of which the fields are all initial.
Any thoughts on what might be going on here?

Hi friend,
I too faced the problem what you faced.
Near to it.
Ill explain you .
YOu have your model node.
1st you will map that to component controller And from there to view controller.
After that you will bind the elements in this node to some elements in your view after that .
For example
Model class name:-Lok_model.
In the DOINIT method:-
write this code.
Lok_model k = new Lok_model(); wdContext.nodeLok_model().bind(k);
Suppose you have a button in the onaction you write this code.
wdContext.nodeLok_model().currentLok_modelElement().modelObject().get_details();
Ill expalin you about this statement Lok_model() is the node in my view which is mapped from the model and by using that i am calling the method get_details() which is in my model class Lok_model.By this data will be automatically populated into the view elements which are being binded to the model attributes.
Hope this helps you,
Lokesh
