Geeting exception while executing BPM webservice from webdynpro.

I have created a webservice to start BPM process.
If I am testing from webservice navigator it works fine and BPM task gets created in my UWL. But when I execute this webservice from webdynpro I get the below error
Exception on execution of web service with WSDL URL 'http://pepu56:50000/bpm/demosapcom/lngtranslationprocess/StartService?wsdl' with operation 'NewOperation' in interface 'TranslateBPMWSDLFile'
Please note that : I have deleted the output part from both binding and PortType section of this webservice.

I was doing a silly mistake. I was not running my webdynpro application from portal. I was running my application through "Deploy new archive and run" option.
I got this clue to run this app after login into portal from the fact that when I was running webservice from WSNavigator I was prompted to pass user credential to execute this service. I had not given any authentication option while creating web service, so just guessed if I run it from portal my user credentials might be taken. And it worked for me.
I really don't know why I was asked for user credentials in WSNavigator and how my user credentils would have taken when I ran this app from portal. But this is how I am not getting this error.

Starting BPM from Adobe PDF?

Hi everyone,
we want to implement a BPM scenario, which will be started by a WS call from an Adobe PDF file. Following is our development procedure:
1. Create a wsdl file, which has only input parameter. (asynchronous call).
2. Create a bpm with a start event, whose trigger is the wsdl file from step 1.
3. Deploy the bpm and configure all the service groups. Test the bpm and find out it can be started with a webservice call.
4. Create an xdp file using the wsdl file from ce as data connection. (this wsdl file is not from step 1, but the one with endpoint configuration from ce)
5. create pdf file from xdp and call the bpm, but failed.
Our questions are:
1. is it possible to start a bpm from a pdf form using ws?
2. if 1 is true, how can we do that?
thanks a lot for your time and reply in advance.
best regards
Xiang

Hi Xiang,
One more information, currently "Starting BPM From Online Adobe is supported". You have to invoke the WSDL as you do for any other online application like webdynpro.
But invoking from Adobe makes sense only if it is done via offiline form (sent through mail). For this functionality you have to wait till release of 7.3.
Hope this is helpful to you.

Debugging is not working in R/3 from WebDynpro-ABAP developed webpage input

Dear Friends,
We are facing a serious problem for debugging. Expecting valuable input for the same.
Debugging is not working in R/3 from WebDynpro-ABAP developed webpage input in Production Server.
The debugging (for WebDynpro-ABAP application) is working in Dev. Server for
1st ] Within R/3
Ex. debug for bapi within R/3. i.e. value enter as input in R/3 only.
2nd ] From webpage to R/3
Ex. Some input given on the internet web page developed through WebDynpro and external breakpoint set in R/3 it works. It directs to R/3 code through debugging.
In Prod. Server the 1st case above is working but the 2nd case is not working.
In Prod. Server the WebDynpro developed applications are running successfully through internet explorer webpage inputs. So running the application is not a problem in prod. Server but debugging of the same is the problem.
The setting which are done in Prod. server are,
1] RZ10 in parameters are set for port and host name.
2.1] In SMICM check for ICM.
2.2] Host file updated in Windows-System 32.
3] In SICF following services are active,

Error when Interative Adobe Form is called from Webdynpro ABAP.

Hi Experts,
I trying to call a Interactive adobe form from ABAP Webdynpro application but I am facing the below error.
Line: -
The following error text was processed in the system GJD : User session (HTTP/SMTP/..) closed after timeout
The error occurred on the application server az18u021_GJD_01 and in the work process 0 .
The termination type was: ERROR_MESSAGE_STATE
The ABAP call stack was:
Method: PREPROCESS_REQUEST of program CL_WDR_CLIENT_ABSTRACT_HTTP===CP

Line: -
When I uncheck the enabled property of the Interactive From in the Page of the WebDynpro I am able to execute the application successfully.But the Adobe form behaves as a Static Form when I uncheck the enabled property.
So kindly provide your valuable suggestions to avoid the above error when I am calling a Interactive adobe form from Webdynpro ABAP.
Thanks in Advance.

Hello,
Hello, are you sure you have your ADS credentials configured correctly and valid? I guess you know that is the only difference between clicking enabled on true or false. If you are not sure, you can use SE38, search for FP_* and pick some reports to check the licencing. The names of the reports are good enough to recognize the right one.
Or maybe that is a security problem? Have you checked the ADS_ERROR string? Did you use the ADS trace?
check: http://help.sap.com/saphelp_nw70/helpdata/en/2c/241a427ff6db2ce10000000a1550b0/content.htm

Update data in r/3 from webdynpro using bapi

Hi ,
i am new to webdynpro.
i want to update data say sales order in r/3 backend from webdynpro.
can i have some links for the same.
i have seen previous forums in following link, but couldn't open.do i need to register to have some extra rights.
/thread/12846 [original link is broken]
thanks in advance

Hi Satya
In order to update data in R/3 from web dynpro you need to use RFC or BAPI
The Adaptive Remote Function Call (Adaptive RFC) is a technology that enables the Web Dynpro application developer to use the business functions encapsulated in Business APIs (BAPIs) even after a structure modification, without having to provide the new data using a second back end or a new structure with subsequent regeneration of the proxies.
Procedure for Importing Adaptive RFC model is as follows
1. Choose the context menu entry Create Model on the Models node of the relevant Web Dynpro component.
2. In the model wizard, choose Import Adaptive RFC Model followed by Next.
3. Make the required entries for example, to specify where the generated RFC model instances and RFC metadata are to be stored.
4. In the next wizard window, you enter your user data for the SAP System that contains the BAPIs from which you want to generate the proxies. You use it to log on to the SAP System online.
To be able to log on to the SAP System, it must be entered in the logon group.
5. Next select the BAPIs for which you want to create Java proxies in a generation process. Then choose Next to proceed to the next wizard window.
6.The import log provides information about the generated model classes, properties, and model relations. Choose Finish to start the generation process.
Now add this model in "Used Model" for your application
Now for graphic display you create view,for the progarm control create controller and used this model to retrieve & update data.

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,

Hi Gareth,
I was not getting enough time to reply, so replying late.
Actaully the problem was with r/3 BAPI Code itself.
There was condition in the begining of the code to check the data in the workare of R/3, so this condition was failing here.
But when we try to invoke that bapi from r/3 workbench it works fine because the data first comes to R/3 workarea then to R/3 Tables.
But when we insert data from Webdynpro framework , the data directly goes to R/3 Tables rather than the R/3 Workarea. So in Bapi the first condition was failing and no data was getting inserted.
So this was the problem, and we solved it.
Thanks,

How to get the complete data from Webdynpro using a RFC

hi guys,
A form is created in the webdynpro, when that pdf form is called the user have to provide the key field ie the employee number in the form and then when he press the 'go' button a rfc is called and it gives all the details of the employee in the form. Then the user have to input some fields in the form and he have press the submit button. My problem is here, when the user is going to press the submit button that form will be converted to a stream (binary) of data and it is sent to one of the import parameter used in the RFC.
I have created a RFC and created a import parameter of data type XSTRING, since i want to see what exactly R3 is receiving from web dynpro i am writing this contant in the sever as a text file. When i saw that text file i cant see the complete data.
And when i searched in R3 the capacity of xstring is 1024 CHAR, so i dont know how to capture the entire data from webdynpro into my R3.
I give the code what i worte please tell me am i missing anything in my code, or is there any data type which can hold more than 500kb of data which is coming from webdynpro.

You have to convert your long string to a table of shorter strings.
There may be other ways, but one possibility is to use a loop to process you string.
while (there is something left)
   put the next e.g. 1024 characters in a new row of your table
endwhile
If you need to reconstruct your string from the table, don't use simple concatenation since it will remove blanks at the end of lines. Believe me (from experience) sooner or later this will happen.
Instead you need to either set the subsections of your long string, or insert from the end of your table and keep shifting the contents (probably less efficient) right

Hi,
I think the binary file conversion was not done properly( you haven't filled bin_pdfx, its the otf_data ). OR, Use CONVERT_OTF FM and pass format as PDF. Check this document for reference: Opening a Smartform in Web Dynpro ABAP

Adobe form from webdynpro : Getting a single row in the table

Hello,
I have a scenario in which I have to create a adobeform from webdynpro application.
I have created the form and have the context designed in place.
I am facing a problem in the table I have in my adobeform.
I am adding rows to this table dynamically using a button using "addInstance"
Now on the webdynpro side , when I try to read this table I get a single row from this table.
This row is always the first row of that table.
I checked the following things from blog   /people/juergen.hauser2/blog/2006/09/12/avoiding-common-mistakes-when-using-tables-on-sap-interactive-forms , i.e. :
Cardinality of the node.
Tick on the option "Repeat Row for Each Data Item".
But still no success.
With deadlines to catch I had to post this question after trying a lot.Please help.

Hello Otto,
I had found this link before and used the same solution , but unfortunately is taking a long time.
Now what I am doing is :
1. I append 10 rows into the table then bind it to the node
2. Then on the adobe form I have removed the check on "Add row for each line item" because of which it shows only 1 row
     on the form.
     Now I add rows dynamically, but this puts a limit on the number of rows can be added to the table i.e. 10.
But this again has added problems like while displaying the form or modifying I hav to handle it seperately and cannot use the same form as it is.( as I have removed the tick for "Add row for each line item" ).
Thanks,
Omkar Mirvankar

Calling a method in Class from webdynpro

Hi All,
I have to perform some action when i click the button created in my webdynpro screen.
However I must not write the code for the button action inside the button event. But I have to create a class and inside the class i have to create the method for this button event.
Can anyone tell me how to call a method in a class created in SE24 from webdynpro on clicking the button.
Thanks in advance.

hi..
When you want to perform some action after clicking a Button, then you have to write the code only in 'Events' - 'On Action' event. From your question, i assume that, you wanna use Assistance class in your webdynpro so as to increase better performance. Here is the link which will guide yuo with screen shot for using assistance class in WD-ABAP.

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.
Best Regards,
