Web dynpro using a portal service

Hello All,
We are using the JDI.
We want to use a portal service DC from a web dynpro DC.
The web dynpro DC is part of a software component.
When the portal service is a local DC it is working fine (except failing later on the CBS build)
but when the service is part of a software component as well I get a runtime exception: a java.lang.NullPointerException.
The WD sharing reference I'm using is: PORTAL:sap.com/<dc service prefix>.<service name>
I assume that this is the right reference because without this exact phrase I get a java.lang.NoClassDefFoundError: com/sap/<name of service>
Does anybody know how to use a portal service that is part of software component?
Thanks a lot in advance, Adi.

Thanks Bharathwaj , but I already solved my problem.
The solution was to change the next code line in the service client code :
Idb_srv DB_Service = (Idb_srv) WDPortalUtils.getServiceReference(Idb_srv.KEY)
to:
Idb_srv DB_Service = (Idb_srv) WDPortalUtils.getServiceReference(""<PARFilename>.<service name>");
Regards, Adi.

Prob. exec. print job from RFC which im calling Web Dynpro java in Portal

Hi,
Ive got a problem executing a print job from an RFC which im calling in Java web Dynpro Application in Portal. Im using an Acess Method G: for Front End Printing but Order gets stuck with the Status "Waiting" "Front end unavailable".
Any help would be greatly appreciated.
Thanks in advance!!!

HI,
I dont think you would be able to do this. Instead, you need to get the content from RFC into WD java and print from the browser.

Not able to run web dynpro application from portal.

Hi portal experts,
I want to run my web dynpro application from portal.
So created a seperate iview and a role for the purpose.
Assigned the iview to the role and also mapped a abap user id to the new role created.
But when I click on 'preview' the iview , getting the following dump.
Error when processing your request
What has happened?
The URL http://mnghcmsap:8000/sap/bc/webdynpro/sap/zhr_cp_admin/ was not called due to an error.
Note
The following error text was processed in the system HRM : Die URL enthält keine vollständige Domainangabe (mnghcmsap statt mnghcmsap.<domain>.<ext>).
The error occurred on the application server mnghcmsap_HRM_00 and in the work process 0 .
The termination type was: RABAX_STATE

What can I do?
If the termination type was RABAX_STATE, then you can find more information on the cause of the termination in the system HRM in transaction ST22.
If the termination type was ABORT_MESSAGE_STATE, then you can find more information on the cause of the termination on the application server mnghcmsap_HRM_00 in transaction SM21.
If the termination type was ERROR_MESSAGE_STATE, then you can search for more information in the trace file for the work process 0 in transaction ST11 on the application server mnghcmsap_HRM_00 . In some situations, you may also need to analyze the trace files of other work processes.
If you do not yet have a user ID, contact your system administrator.

Please let me know if I am doing the process correctly and also let me know if I am missing somthing.
Thanks,
Aditya.

Are you able to run teh web dynpro application independtly i.e. without creatin an iview.
http://mnghcmsap:8000/sap/bc/webdynpro/sap/zhr_cp_admin/ by using this link.
or there also you are getting the error.
i guess there also you should be gettign the error.
this is some problem with the FQDN settings in the abap system.
in the host name of the web dynpro applciation server one .(dot) is must.
so you might have to change the host name to some thing like mnghcmsap. from mnghcmsap
thanks

Error when Creating Web Dynpro Model in CAF-Service

Hi All,
I reaaly need help. AFter updating to SPS 9, it was necessary to redeploy my Entity Service. That contains to "Create a Web Dynpro Model" in the Service Explorer,
to get an interface of the Service in my Web Dynpro Application.
Before I update to SPS 9, the Application works fine.
But now, when I want to "Create a Web Dynpro Model" in the NWDS I get the following Error-Message (its not a useful Error-Message):
Error cannot create Web Dynpro Model:
Creation of Web Dynpro model failed. Reason: null 
Thanks for helping me
Steve

Hi Aliaksei,
the problem in the thread is the same I got.
When I use only 7 letters for the operation name, the creation work. When I use more then 7 letters the creation doesnt work.
But its hard to find a methodname with only 7 letters.
In SPS 8 I didnt have problems with the length of method names. Why is it so?

Search help for Web Dynpro using the SAP-search help

Hi,
Im trying to create a generic search help for Web Dynpro using the SAP-search help. It should working so, that I construct a Web Dynpro-component, that gets the data of the search help from the SAP-system, interpreted it and creates the ui-elements and the needed context generic.
The mapping between the Input field of the customerview and the right search help is to be made with an xml-file, which contains the information: name of the view, the input field, the search-help-name and the name of the field that will be returned.
The xml-file is reading from a helper-class. That helper-class contains any information, witch need the search help-component as well as the customer-component.
The initialization takes place in the method wdDoModify of the customer. The call of the search help from the customer should be implement with an Action, witch is bound to a Button(create dynamic in the helper-class behind the input field).
In a second foot should be create a plugin for eclipse, witch insert the used files (search help component, helper class, ) in the project. In addition it should create the call in the customer generic.
It would be great if someone can give me a feedback!

Hi Mike,
The BlanketAgreement.exe is a reference to the executable that will be created when you compile the solution you created in Part II - Part III. I think there is a mistake in the tutorial because it asks you to name the project 'Blanket' which means that by default the executable will be called Blanket.exe and not BlanketAgreement.exe. The tutorial also misses the step asking you to compile the Blanket project before you go on to create an installer. You should compile your Blanket project in Release mode before creating an installer. By compiling the project you'll get a Blanket.exe file in the bin folder of your Blanket project which you then need to add to the installer per the instructions.
SAP do offer development courses in some areas and there is training material here on the SDN and on the SAP partner portal (and maybe the customer portal as well). Try searching this forum for 'training' or 'tutorial' and you should get a few links. There's also a development certification.
Personally I'd recommend you give yourself a little project to work on and just get stuck in
Kind Regards,
Owen

Hi,
I think ur webdynpro service is not active after upgradation.
You have manually activate it.
Go go Tcode SICF,Execute the Initial screen,
and in this new screen give service as your application name and click on filter.
You will get your service below which will be ur application name .
right-Click on the deactivate and activate it or just activate it,.

Using a Portal Service

Hi,
Am trying to use a portal service in my application and calling a method,it should return me the IResourceList which am going
to iterate and publish the Resource.
Interestingly,am getting the error "Build of the project Failed" Pls Note am working on JDI or NWDI & no compilation errors
at my end.
Please find the Code below :
user =(IUser) UMFactory.getUserFactory().getUserByLogonID(request.getUser().getLogonUid());
IPortalRuntimeResources runtimeResources =PortalRuntime.getRuntimeResources();
IService aService = runtimeResources.getService("customer.MyService");
customer.MyService tmp = (customer.MyService) aService;
IResourceList list=(IResourceList)Util.getMethod(filterbasepath,arraylist,user);
Any help in this direction would be highly appreciated,kindly be specific as where have i gone wrong.
Regards
Manoj

Hi Harish,
1.Other components in the par file do not have classes with syntax error.
2.deployement descriptor has correct syntax.
3.deployement descriptor has services reference to the Portal Service am using.
if i comment some part of the code say
user =(IUser) UMFactory.getUserFactory().getUserByLogonID(request.getUser().getLogonUid());
IPortalRuntimeResources runtimeResources =PortalRuntime.getRuntimeResources();
//IService aService = runtimeResources.getService("customer.MyService");
//customer.MyService tmp = (customer.MyService) aService;
//IResourceList list=(IResourceList)Util.getMethod(filterbasepath,arraylist,user);
i can upload the par file,that clearly indicates that
theres some problem in using the service "customer.MyService",though there are no compilation errors.
I have even tried the alternative
IService aService = runtimeResources.getService("IMyService.KEY");--->where IMyservice is the Interface Class.
Regards
Manoj

How to make use of Portal service in the web dynpro application

hi
I have some portal service and how to use that in the web dynpro application.
and also what is the main diff between Portal Component and web dynpro application.
do we required portal to run web dynpro application.
thanks
mmukesh

Hi,
>> I have some portal service and how to use that in the web dynpro application.
Yes. U can use Portal service in webdynpro. Check the link given by subathra.
>> and also what is the main diff between Portal Component and web dynpro application
Portal Components are components designed to run in portal server while webdynpro application can run in J2EE WebAS.
>> do we required portal to run web dynpro application.
No for general cases. Just WebAS is sufficient to run webdynpro appl. But if u use portal service in ur webdynpro appl, then make sure both (portal service and webdynpro appl) run on same J2EE engine. That is mandatory.

When to use WEb Dynpro application and Portal application in NW dev studio

I would like to know what is the difference between
webdynpro application and EP Application using PDK.
Are they comaparable ...Which one has an edge over the other specific to any applications.
I want develop an application related to e-commerce using the SAP R3 as backend for an industiry(where in a registered user can place an order and query on the staus of order. All the data will be stored in R3 ).
I am planning to dev this using NW dev studio , but have an appehension about which application is useful for this kind of application either webdynpro or EP application .
can anybody explain which one has edge over the other ( Webdynpro or EP applcations in context with NW Dev studio) and why.
thanks

Hi,
Webdynpro is used when requirements ask for a prototype using minimal time n effort.
Highly skilled programmers are not necessary to write a webdynpro application
It uses dynamic controls without reloading the page.
Portal components esp Abstract portal component provides a lean method to write HTML command to web client
Large interactive components requires more programming.
WebDynpro is a highly declarative, tool-based programming model. It minimizes platform-dependent "plumbing" code for building UIs and maximizes declarative metadata describing huge portions of a typical application in a platform-independent way.
Web Dynpro follows a "top-down" approach in order to consistently support multiple runtime platforms.
In Web Dynpro you just have to drag & drop the UI components.
Portal components has followed a "bottom-up", programming-driven approach to Web development.
Regards,
Pooja.

Hi Mahesh,
You need to setup a Single Sign On between SAP Portal and ECC system where yoy are doing the development.
Ask basis team to setup the single sign on and usually this is the job done by Basis teams. Refer the below link to get some idea on SSO setup:
