Invoking the Portal Service DC from Webdynpro Java DC

Hi experts,
I am trying to Call a dc Portal Service from within a Web Dynpro DC
following the steps I did,
1. Created a DC "Portal Application Standalone" project by the name "portappstd".
2. Created a portal service inside "portappstd" dc by the name "DemoPortalService".
3. Exposed ITestService.class in the public part.
4 Build and deployed the DC on server!!
Now..
5. Created anoter DC of type WebDynPro named "demoportaldc".
6. Added SAP_JTECHS -> epbc.prtapi._api as a "Used DC" with dependency build time and runtime
7. Added IDemoPortalService.class from the public part of portal Service as Used DC
8. Tried to reference the service using the following code..
IDemoPortalService service=(IDemoPortalService)WDPortalUtils.getServiceReference(IDemoPortalService.KEY);
9. Build and deployed the DC.
10. When I run the application I am getting the following error
Processing HTTP request to servlet dispatcher finished with error.
The error is:
application [webdynpro/dispatcher] Processing HTTP request to servlet [dispatcher] finished with error.
The error is: com.sap.tc.webdynpro.services.sal.core.DispatcherException: Failed to start deployable object com.arteriatech/demoportaldc.
so, please do the needfull ASAP,..
Thanks & Regards,

I need to set a proxy to visite internet, when i invoke the firefox 3.6 from my Java code, my setting would be disappeared. So i wonder whether the fire fox has the start up parameter to control this, thanks!

1: I need to set aproxy in firefox 3.6, which allow me to access the internet.
2: Currently i am using some Java code to invoke the firefox, the path is D:\Program Files\Mozilla Firefox\firefox.exe. When the firefox launched by Java code, I found the proxy is missing.
3: looks like the Java code make the firefox go back to the orininal status, just like the fresh installation.
I wonder whether there are some parameters or files that can be used to control the firfox starting.

Thanks for your reply, here is what i tested:
1: Upgrade my Firefox version to 3.6.8
2: The installation path is D:\Program Files\Mozilla Firefox\firefox.exe
3: For the ProfileManager, I tried to run the firefox.exe -ProfileManager in command line, the firefox was started up but not the profileManager. No sure why this happened. :-(
4: I updated some features after the installation, like add some bookmarks, delete some default bookmarks and added the proxy. When the firefox is started from my code, the profile would be the default one(No new bookmarks, no proxy).
5: Start the firefox from the command line and by double click is ok, my adding bookmarks and proxy is here...
Thanks!

Reg: calling default desktop page of enterprise portal from webdynpro java

hi Experts
Here is an scenario where i need to call enterprise portal desktop from webdynpro java application.
Actually i have designed a custom Home page in WDJAVA and this page i have assigned as default frame work page in enterprise portal ,so once we logon through the portal URL wewill be getting this custom home page as default page and when i click on next button it should connect to the predefined SAP given default frame work page.
The thing is i am able to see the custom page and the button but when i click on the button it is opening the same custom home page only not able to log on to portal default frame work page.
My question is how can we connect to the predefined page from the custom home page.
please share your regarding this scenario...
regards & Thanks

hi Experts
you didnt get my point i vl give in brief
1) that at first we are going to enter the portal URL.
2)we are going give userid and password and click logon button.
3)so once we click on that button it should open custom page what we have designed in by using web dynpro java.with in this application we will have next button which should connect to the sap given predefined default desktop page.
i hope you have got my point.
and more over where can we get the logon action coding in which par file,if so can you give brief information related to it.
i changed the themes master rule collection there i have assigned this custom home page ,but when i click on next button it is opening the same custom it is not connecting to the default desktop.i think this is not the write approach.
please share your knowledge and document also related to it.
Thanking you

Call stateless session bean EJB 2.0 from Webdynpro Java UI

Hello,
Can someone please tell me asto how to call a stateless session bean EJB 2.0 from Webdynpro Java UI?
The NWDS version is 7.0.
Thanks and Regards,
Arya

Hi Aryadipta
Please check this pdfs
https://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/b00917dc-ead4-2910-3ebb-b0a63e49ef10&overridelayout=true
Steps for calling stateless session bean in Webdynpro java
Go to NWDS -> open perspective ->j2ee
select EJB Module Project ->create a project with name
Open the Project -->RC on ejb-jar.xml -> Select new --> EJB
Give name to EJB Bean (First letter should be in capital letters)
select the type of bean as Stateless session bean and give the package name to store that EJB bean.
After that Expand ejb-jar.xml and then select the <projectEJB>
Double click on this on method tab double click you will get business method where we will create the methods for business logic
Double click on projectEJB and then RC on bean tab and write required business logic in bean window as follows(based on requirement we will design a business logic).
After writing the business logic go to project -> rebuild
Till now we have created one EJB jar file
then go to File-->Enterprise Application Project -->create a project (projectEAR)
After creating a project click on next-> here we will have ear projects and then we select specific project required for our application.(here select projectEJB)
After that Calculate EAR project will be available on j2ee explorer.
Right click on <Bean> here
select New->Web Service->give a name to webservice and select Default configuration type as simple SOAP
-->click next -> Finish.
That webservice and related are created in ejb-jar.xml .
Expand the ejb-jar.xml.and double click on < webservice>
RC ProjectEJB -> Build EJB Archive RC on CalculateEAR ->Build applicationarchive.
Expand the projectEAR->RC on CalculateEAR.ear->Deploy to J2EE Engine
Double click on calculateEAR.ear ->Webservice navigator tab ->we eill servers expand the node
select the specific WebService
Here we test the webservice by click on Test and test it.
After that go to Web dynpro perspective ->create one webdynpro Project and one component
RC on model> Select import Web Service model(last)>give model name and package
and select radio button as local file system or URL
Go to WSnavigator->copy the WSDL path and paste it in model WSDL path and click on finish.
from here onwards steps are same as that adaptive RFC model
Hope it helps
Thanks

Consuming PI Webservice from Webdynpro Java Not working

Hello SAP,
Environment: CE 7.2.
Resolution expected immediately, Helpful answer is highly appreciated.
Is the namespace should not exceed 60char for PI Webservice, for executing the webservice from Webdynpro Java.
I tried with all the options in executing the PI Service from Webdynpro Java, None of the options worked. I am facing the below error while I was calling the PI Webservice.
I don't see any problem from Webdynpro Java, what ever the procedure I have followed is the standard procedure.
Fortunately when I execute the service from Webservice Navigator, it is working as expected. The same webservice when I consume it from Webdynpro Java it is not working
Options tried so far:
1) Published the Services to Service Registry and there by consuming the PI Service from Service Registry - Not worked
2) Tweaked the URL with few options - Not worked (Tweaking the URL, ex: portType, Binding)
3) Changing the Business Systems in PI and there after calling the service - Not worked
4) Initializing the code, instead of creating Service Controller and calling the PI Service - Not worked.
5) Created a Provider System and tried to call the PI Webservice from Provider System - Not Worked
For all the Options, I am facing the same error which is provided in the screenshot.
Below procedure which I have followed for calling the PI Webservice:
1) Created Adaptive Webservice Model
2) Provided PI Webservice URL (It prompts for PI System UserId and Password)
3) Selected Option - No Service Group Configuration
4) Provided Logical Destination
6) Completed creation of Model
7) Added the model as a UsedModel
8) Right Click on Comp Contr. and selected Apply Template and Created a ServiceController for the model (Entire mapping to comp contr, Initializing the nodes is taken care by Service Contr.)
9) Created an Template Action button and there by calling execute method which is auto rendered from CompContr..
10) Build the project.
11) Activated the code and Run the Application.
12) Getting the below error which is showed in the message.
ERROR MESSAGE:
Exception on execution of web service on destination 'GetPIHRPeopleData' for operation 'SI_CreateHRPeopleData_OS' in interface 'SI_CreatePeopleCompany_OS'

Hi Sankar,
If the webservice is working fine in the Wsnavigator then there is some problem with importing the webservice in webdynpro for Java. Please check the required parameter for creating the Adaptive Webservice Model. After adding in the used model and compoent controller binding, you need to write code for to execute the webservice model.
Please check the code for initialization and execution for the webservice and then test it.

pls help in resolving this

Assuming this is for Oracle BPM 11g.
I'm a novice at this and sure others will have infinitely better ideas (have I lowered your expectations enough?), but here are two thoughts. Both of these ideas assume that your child process was invoked by an Oracle BPM parent process.
When you expose a process as a web service and invoke it asynchronously from a parent process, there is a call back service available. I've yet to figure out exactly how to get it to work, but if you look at the "Start" event's property in the composite (it's the service) you will see the callback information in the bottom dropdown. I believe what this means is that from your child process, you can use a Service activity to invoke a service that invokes the callback service back to the parent process's Service activity.
My other idea (you're not going to like this one) would be to to invoke the subprocess using a Message Start Event activity instead of the Service activity you're currently using. If you go this route, then you could have your parent process kick off the child subprocess using a Message Start Event activity and then immediately after this have a Message Catch Event activity. The child process could have a Message Throw Event activity immediately after its Start Message Event activity that sends a notification to the parent process. The good part about this is that I've actually gotten this to work.
You can send argument information back to the parent process, but (sorry) I don't yet know how to capture the process id.
Wish I could be of more help and hope this helps a little.

How to specify file name while invoking the GET_ZIP_BUNDLE service

Hello.
The GET_ZIP_BUNDLE service by default generate zip file with name "Bundle". I wanted to change this name runtime, that is while invoking this service. How can I do it?
The class ziprenditions.ZipRenditionsHandler most probably handle this service by the method createRenditionBundle.
There I saw a line:
downloadName = LocaleResources.getString("csZipRenditionBundleName", this.m_service);I have tried to print the value of csZipRenditionBundleName and I got "Bundle". I am wondering is there any way to set a value to this message key?
I have tried this idoc function:
<$createRenditionBundle='some_name'$>before invoking the service. But this didn't work.
Also I have tried to change it from Java class, and for that I have defined a custom service and did:
LocaleUtils.encodeMessage("csZipRenditionBundleName", null, "JYM");But this also not working.
What I want is to get the zip file with the name which is the same to the files it is archiving.
For more information, here is how I am invoking the GET_ZIP_BUNDLE service:
I have defined a form element:
<form action="/cs/idcplg" method="POST" id="zipBundleForm" name="zipBundleForm">
   <input type="hidden" value="GET_ZIP_BUNDLE" name="IdcService">
   <input type="hidden" value="pkg:dDocName,pkg:dID,pkg:Rendition,pkg:RevisionSelectionMethod,pkg:AuxRenditionType" name="bundleKeys">
</form>And I have a button with id downloadContent and I have attached the following JavaScript with it:
$('#downloadContent').click(function (event){
   event.preventDefault();
   var formId = "zipBundleForm";
   var counter = 0;
   var renditionType = "";
   $("#zipBundleForm").find(":hidden").each(function() {
      if($(this).attr("name").startsWith("pkg:"))
         $(this).remove();
   $("#downloadContentForm").find('input:checkbox:checked').each(function() {
      renditionType = $(this).val();
      $(".thumbnails").find('input:checkbox:checked').each(function() {
         if($(this).attr('data-type') == 'image'){
            createHiddenInputElement(formId, "pkg:dDocName" + counter, $(this).attr("name"));
            createHiddenInputElement(formId, "pkg:dID" + counter, $(this).attr("id"));
            createHiddenInputElement(formId, "pkg:Rendition" + counter, renditionType)
            createHiddenInputElement(formId, "pkg:RevisionSelectionMethod" + counter, "Specific");
            counter++;
   $("#zipBundleForm").submit();
var createHiddenInputElement = function(formId, elementName, elementValue){
   var newElement = document.createElement("input");
   newElement.setAttribute("type", "hidden");
   newElement.setAttribute("name", elementName);
   newElement.setAttribute("value", elementValue);
   $("#"+formId).append(newElement);
}Thanks in advance.

if you want a fixed bundle name other than "bundle", you can override the localization string entry 'csZipRenditionBundleName' in a component.

Access "Business Intelligence Consumer Services (BICS)" over WebDynpro Java

Dear all
I have to access the SAP BI from WebDynpro Java.
At the moment I do this over the BI-JAVA-SDK which has unfortunately no integration with the BEx-QueryDesigner.
Therefore my question:
1. Is it possible to access the SAP BI over the "Business Intelligence Consumer Services (BICS)"? And if yes, where can I find the corresponding documentation? (I have not found it by myself)
2. What is your preferred way to get data from the SAP BI in WebDynpro Java?
Greetings

Has anybody created Iview from "Webdynpro Java" component in CE7.1 ?

Hi All,
Has anyone created Iview from Webdynpro Java component in CE7.1.
Because the wizard that appears for creation of Iview has only "Webdynpro ABAP"
component.There is no option to create iview from "Webdynpro Java" component.
Althought in portal content--->Template folder i can see there is also
another template for "SAP Webdynpro iview" which i think is for the Java scenario.
But issue is, its not coming in the wizard.Can anyone tell me how to make it appear in the wizard ? It will be of great help to me.
Thanks and Regards
Ashis

Hi Ashis,
your deployed webdynpros are published under "web dynpro applications". just copy the webdynpro from there and paste it into the portal content section.
http://help.sap.com/saphelp_nwce10/helpdata/en/ce/e0d6f54ae641fc9566501cffaa8c6c/frameset.htm

Can we access PI tables from WebDynpro Java via PI 7.1?

Hi Experts
Is it possible to fetch PI Tables (to display monitoring and alerts as dashboard on portal) from Java Stack. I got some javadocs API SAP Netweaver for PI 7.1 but i don't know how far it can help me in solving my purpose of fetching and displaying the PI monitoring data on Portal.
https://www.sdn.sap.com/irj/sdn/javadocs
Please advise if J2EE access to PI Tables is possible or RFC is the suggested solution to fetch PI Monitoring data.
Thanks
Neha

Hi Neha,
You can access PI tables from Webdynpro Java application using RFC or Webservices. Create RFC or Webservices which will fetch data from the PI tables.Create the required JCO's and the Webdynpro java application which uses the Adaptive RFC model or Adaptive Webservice Model to connect to the ECC system.
I found a document that speaks about fetching data from SXMB_MONI Standard Table https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/b050ff4f-84c3-2b10-3d99-8f9c44f57a17

Trigger MDM workflow from Webdynpro Java

Hi All,
After updating records in MDM, I want to trigger an MDM workflow from Webdynpro Java and pass those updated records to workflow. Any inputs on how to accomplish this. Workflow has already been developed using MSVISIO by the MDM team.
Thanks,
Tom

By following steps, it is possible to integrate workflow (or any workflow designed in MDM) within portal:
1. UWL (Universal Worklist): The UWL gives users unified and centralized way to access their work and the relevant
information in the portal. It collects tasks and notifications from multiple provider systems. One can expose MDM
workflow functionality on Portal using UWL.
2. JAVA APIu2019s: MDM Java API consists of set of classes related to MDM workflows through which one can create an
application that provide the MDM workflow functionality and expose the application as an iView in the portal.

Passing Parameters via Post Method from Webdynpro Java to a web application

Hello Experts,
I want to pass few parameters from a web dynpro application to an external web application.
In order to achieve this, I am referring to the below thread:
HTTP Post
As mentioned in the thread, I am trying to create an additional Suspend Plug parameter (besides 'Url' of type String) with name 'postParams' and of type Map.
But when I build my DC, I am getting the same error which most of the people in the thread have mentioned:
Controller XXXCompInterfaceView [Suspend]: Outbound plug (of type 'Suspend') 'Suspend' may have at most two parameters: 'Url' of type 'string' and 'postParams' of type 'Map'.
I am using SAP NetWeaver Developer Studio Version: 7.01.00
Kindly suggest if this is the NWDS version issue or is it something else that I am missing out.
Also, if it is the NWDS version issue please let me know the NWDS version that I can use to avoid this error.
Any other suggestion/alternative approach to pass the parameters via POST method from webdynpro java to an external web application apart from the one which is mentioned in the above thread is most welcome.
Thanks & Regards,
Anurag

Hi,
This is purely a java approach, even you can try this for your requirement.
There are two types of http calls synchronous call or Asynchronous call. So you have to choose the way to pass parameters in post method based on the http call.
if it is synchronous means, collect all the values from users/parameters using UI element eg: form and pass all the values via form to the next page is nothing but your web application url.
If it is Asynchronous means, write a http client in java and integrate the same with your custom code and you can find an option for sending parameters in post method.
here you go and find the way to implement Asynchronous scenario,
