Dropdown data from WebDynpro Java

Hi Experts,
Is it possible to dynamically populate dropdown items from the Java WebDynpro context which are in turn populated using an aRFC from SAP R/3? If so, how do i go about in doing this?
Cheers,
Alfonso

Hello,
To dynamically populate Drop downs inside adobe form you can have two approaches:
1. Dynamically populate the simple type using Modifyable Simple Type. Associate this simple type with a context attribute. Map this context attribute with the dopdown in form desinger.
2. Second approach is to loop at the possible set of values inside the form designer by using java script. Then populate the dropdown enumaration in this for loop

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
Hope this is useful.

View Object to read data from a java file

Hi,
I am using JDeveloper 11.1.1.4 and ADF-BC in my application.
For one of my view objects , I want the data to be read from a java file which exposes some method to return a collection.
I cannot use a static view object in this case.
Please suggest the best way to implement this requirement.Basically build a view object that should read data from a java file.
Thanks,
Praveen

Depending on your use case you can either use a programmatic VO or directly expose the JV class as a data control.

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,

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

Static lookup lists:read data from a Java *.properties file

Hi
i need to make static lookup lists i am using read data from a Java *.properties file
i am using the Class "PropertyFileBasedLookupViewObjectImpl" that wrote by Steve Muench in ToyStore.
but i need to use the default language for that i update the loadDataFromPropertiesFile()
method to find the correct properties file
String temp=Locale.getDefault().getLanguage();
String propertyFile =
getViewDef().getFullName().replace('.', '/')+"_"+temp+ ".properties";
the problem:
For English(TEST_en.properties) it is good and working
For Arabic(TEST_ar.properties) read from correct file _ar.properties
but the dispaly character is wrong

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,
Arun Jaiswal

How to access internal table data from webdynpro to Flex application.

Hi Connoisseur
The data transfer from Abap WebDeypro to flex island works well. I followed , there is an example from Thomas Jung (by the way as always Great Work) and Karthikeyan Venkatesan (Infosys) but this example covers simple type only.
There is no example with complex types like arrayCollection which handle the transfer of data from flex to WebDynpro.
i tried to do pass internal table value to flex-datagrid.but its not work.
i would like to know
1.how to access internal table data from webdynpro to Flex application.
2.how to pass the internal table to flex-datagrid.
2.how to pass dynamically in ADOBE flex.
3. how to do Flex is receiving the wd context data?
4. how can we update WD context with FLEX data.

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.

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 data from webdynpro to BSP

Can anyone tell me is there any possibility of passing data from webdynpro to BSP and vice-versa.
If so, kindly let me know.
thanks a lot.

Two possible options, not sure however how this will work in practice.
1. use the URL and pass additional parameters (http://help.sap.com/saphelp_nw70/helpdata/EN/7b/fb57412df8091de10000000a155106/content.htm)
2. If in portal, do via portal eventing (http://help.sap.com/saphelp_nw70/helpdata/EN/f6/7d6f4151dc5758e10000000a1550b0/content.htm)

Hi Vijay,
if the BSP application and WebDynpro application both run in the same SAP ABAP instance you can use server-side cookies.
Just because sside-cookie functionality was built for BSP there is no reason you can't use them for any ABAP application.
