Convert Webdynpro Java WebService

Hello,
I have a Webdynpro Java Application deployed on the Portal Server. I want to convert this Application to a WebService and call it from a BSP Application . How can I achieve the same ?
Any help would be highly appreciated.

Hi,
As John rightly pointed out, you cant convert a webdynpro java app to webservice. as wd java is meant for UI developing. But you can convert a RFC to webservice and can use it in your application.
Kindly refer this link for more information:
Converting a RFC enabled function module to a webservice
Hope this will help you.

JIthin

Hello Expert,
Any idea if there is any simplest way available to export view format(data ,layout) in PDF without writing much code or using opensource apis or ADS.
Any suggestions will be useful.

Things like that are normally done with the "Interactive Form" UI Element with which you can use the integrated Adobe Forms environment. For more information have a look at the Integrate Online Interactive Forms by Adobe

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.

Formating the response of Java webservice to table structure in webdynpro

Hi All,
I am stuck at a point where I have a Java Webservice resulting an ArrayList Response.
My webdynpro will have to populate the ArrayList response into a table.
Below is the piece of code am using to execute my webservice.
CODE :
JavajdbcModel md = new JavajdbcModel();
    Request_Display reqDisp= new Request_Display(md);
    try
    reqDisp.execute();
    wdComponentAPI.getMessageManager().reportSuccess("Str: "+reqDisp.getResponse());
RESULT :
<modelObject class="Response_Display"><target roleName="DisplayResponse"><modelObject class="DisplayResponse"><attribute name="Response" value="[[i01111, USSS, DSGTechTwo, DEF], [i012345, USSS, DSGTechOne, ABC], [i067890, USSS, DSGTechTwo, DEF], [i07777, USSS, DSG, ggg], [i08888, cccc, vvvv, bbbb], [io3333, USSS, DSGTechOne, abc]]"/></modelObject></target></modelObject>
The required output are the values that are with the blue font above.
I have tried with methods like :
getAttributeValue, getResult - but are of not much help.
Could you please help me out in this.
Thanks & Regards,
Suyukti. B N.

Dear Suyukti,
Since your web service returns an arraylist,
you need to retreive the response into an arraylist. Then you can you this arraylist to populate the node for the table as required.
Your code will be something like
ArrayList al = (ArrayList)reqDisp.getResponse();
Now that you have the response, then use the get function of the arraylist to set the context.
al.get(index);
This function returns java.lang.Object, so you need to to cast into the required type.
e.g. String str = (String) al.get(0);
Hope that works.
Regards,
Mayuresh.

How to Consume a WSDL file in Webdynpro JAVA Application 7.30

Hi Experts,
My requirement is,I have a wsdl file(Provided by the SAP PI) which i need to consume in Webdynpro Java 7.3(NWDS 7.30).
I has been tried in the follwing way
1.First click on the Model --> Adaptive Web Service Model -->Model Name--Package Name
2.Choose Remote Location/File System.
3.After that choose the WSDL file from my project which i added earlier.
4.After that I get the node in the context menu.But I am uneble to set some data into the node and also uneble to get data data from the node
After deploying my project I get the following error.
Error ::
The initial exception that caused the request to fail, was:
com.sap.esi.esp.service.server.query.discovery.ExtendedServiceException: Configuration not found for service reference with ID: c73e38ff-a4d8-4e4c-89c2-827fd5cf17ac from application demo.sap.com/mwebsrvc.

Please help me about this.
Thanks and Regards,
Amit Basak

Hi Amit,
Create provider system in NWA -> SOA management -> System Connections. After ping is successful go to NWA -> Application Communication and select your DC and assign the provide system for your service configuration group.
I hope it will works fine as we also did the same.

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

Com.sap.tc.webdynpro.model.webservice.exception.WSModelRuntimeException

Hello Team,
We have a scenario where we have a PI web service and we are importing the WSDL into our WD Java application.
While running the test scenario we are getting the below 2 exceptions in the stack trace.
20111222:Exception trace: com.sap.tc.webdynpro.model.webservice.api.WDWSModelExecuteException: Exception on execution of web service on destination 'WS_CUST_**' for operation 'GetCustomer*' in interface 'GetCustomer**'

By running through few posts on SDN a probable solution for this was proposed as: blank the "designtimeWsdlUrl" properties of the model in NWDS and re-deploy the application
Any help on this would be great.
Regards,
Shailesh

Dear Shailesh,
Did you try to check the blank the "designtimeWsdlUrl" properties of the model in NWDS and re-deploy the application? please try to check and test.
Also try to import fresh in new DC and check whether it is working or not.
Best Regards

Using Java Webservices provided by xRPM 4.0 in PPM 5.0

Hi,
We have developed some custom WD ABAP applications in PPM 4.5 which were using Java webservices provided by xRPM 4.0 to get the UI context.
The details are provided in the document
https://websmp109.sap-ag.de/~sapidb/012006153200000315412008E/How_to_xRPM_custom_iView.pdf
We have upgraded to PPM 5.0 and the custom webDynpro application is not able to fetch the UI context and get the portfolio GUID. I have verified that the RFC destination and Logical port required to call Java webservices is maintained as mentioned in the above document.
Are these SAP standard Java webservices available for use in PPM 5.0 ? Please let me know if we need to change the custom code to fetch the UI context in PPM 5.0
Thanks,
Yomesh

Thanks Amit for the confirmation. I am following SAP Note 0001399319 which mentions about how to develop for custom WD ABAP applications in PPM 5.0.
The example WDA component mentioned in the note is /RPM/CUSTOM_COMPONENT. I am developed a custom WD ABAP application in lines with the SAP note and still not able to get the GUID in the context.
The code written in WDDOINIT of these applications is as below,
instantiate session state class
    wd_this->mr_session_state = cl_inm_session_state=>get_instance( ).
Obtain current context from session state.
    CALL METHOD wd_this->mr_session_state->get_current_context
      IMPORTING
        es_context = wd_this->ms_context.
I am getting null in ms_context.
Please let me know if you have tried to implement an custom WDA application in PPM 5.0. Not sure what am I missing in the above scenario.
Thanks,
Yomesh

Null Pointer Exception Error's in WebDynpro Java

Hi All,
How Types are coming Null Pointer Exception Error's in WebDynpro Java, Please provide the types.of Errors.
Ex. Cardinality Type not correct etc...
Thanks,
Bye,
Vijay Hari.

HI
Null Pointer Exception can occur in may instances , for suppose
1) when you create a Value Node with some attribute which has cardinality , and you have not
initialized the Node , then it would through Null Pointer exception ,
2) when you integrate the RFC and parameters you pass as input to the RFC are not set correctly
then there could be null pointer when you execute the RFC
3>or may be when you doesnot bind the node when using webservice then there could be null pointer exception
and there could be many occurances for the exception

Could anyone provide sample of WebDynpro Java TableFilter for Dynamic Table

Hi
I have a dynamic table I have given a context node as a data source and it executes a Web Service and populates itself based on the resultset of query this node contains no of columns and rows
The table changes dynamically everytime the user selects different table type
When I created a TableFilter I used IWDTableColumn from the current view and looped though the context elements and binded the values of attributes of each context element to this column inside a loop. TableSort works, But I am not able to get the Filter working for the Dynamic Table , when I click on Filter Button the Filter does not filterand just sorts.
Not sure what is wrong but if someone can give some inputs,leads I will highly appreciate if some one has a sample of WebDynpro Java TableFilter for Dynamic Table
Thanks in advance,
Ragu.

Hi Ragu,
Please check the link for table filtering.
http://wiki.sdn.sap.com/wiki/display/WDJava/GenericTableFilter+Code
since your dynamic table uses webservice I assume it has fixed context attributes, just put the filter into wdDoModify method everytime you execute/trigger the webservice.
Regards,
