Opening sap transaction in uwl to webdynpro java screen

Hi Poral Gurus
I am new to uwl concept . we are in the process of the Leave apply and approval . the work items are displayed in the sbwp
which comes in uwl . when we click on the item in work list it is opening the sap transaction, but the requirement is there any way to convert the sap transaction view to the webdypro java screen . the screen should not no way look like the sap transaction but it should look like which is developed in webdynpro java using nwds
The problem here is the work item is opening the sap logon when an work item is being clicked and the screen also is not exactly what we look in sbwp. it is having a different look. the screen is becomming small where the user has to use scroll bars to navigate to particular input element,but in sbwp it is showing the full screen.
Please help on this is there any way to solve this problem.
Thanks
prasad

Hi,
Let us know whether you are using the standard Leave request application with standard workflow or customized screen.
If you are using Custom development for the approval screen, then Make sure that you have mapped your custom development screen to the workflow task in SWFVISU.
Then Re-register the UWL system in portal which is available in the below location.
System administration - system configuration - universal worklist and workflow u2013 universal worklist administration - Universal worklist systems - re-register the workflow system.

WebDynpro Java Screen Feasibility

Hi,
I am trying to understand the Feasibility of this Requirements solution from SAP WebDynpro Java perspective.
Requirements-
1)     Design a SAP WebDynpro Java screen. On click of upload button read an Excel sheet which contains Part no1 & Part no2 records. In an excel sheet there is 6,000 records.
2)     Whenever a record is read from the Excel it will search the unique combination of Part no1 & Part no2 in the database (in this case SAP MDM Data Manger). The database contains 7,00,000 records which is not indexed/ sorted..
3)                   6000 times (excel sheet records) step 2 is repeated
4)     For each record the output can be zero, one or more records. The output need to be displayed/ generated in Excel sheet
5)     Concurrently this functionality is used by 5 users.
Question-
a)     Do this requirement can be achieved using SAP WebDynpro Java ? If yes, then from performance perspective how much time it take to upload the excel sheet & create a new Excel sheet functionality?
b)     If No, then why ?
I am trying to understand whether this requirement is Feasible (Y/ N) with valid reasons?
Any valid inputs will be highly appreciated!
Thanks,
Kumar

Hi Robin,
Let me advise SAP MDM administrator to index the database.
1) If it is indexed and if it works then as proximity how much time it take to read and generate an excel sheet ?
2) Suppose after indexing the database is not indexed/ it does not work (limitation from DB perspective) then proximity how much time it take to read and generate an excel sheet ?
This requirement is feasible (Y/N) from WebDynpro Java perspective ?
Also could you please clarify this sentence - "But don't do it while reading the file, the I/O will drain your performance)".
Thank you for the prompt reply.

Creating Packages and Namespace for Webdynpro Java applications in NWDS

Hi Experts,
I am working on a stand alone application and using NWDS for the same. This application consist of some Webdynpro Java apps, Dictionary perspective DC's and BPM applications.
I need to create a package and name space for all the applications. I have read some documents on creating SC in SLD and using it in NWDI. But since I am working on NWDS i am not able to see the SC.
May be I am not following a correct procedure. Can some one provide a basic document or can tell me steps in short that i need to follow, for Name space and package creation and how to use them in NWDS.
I am working on CE7.1 ehp1.

Validation of data fields in the Excel through webdynpro java

Hi all,
I have requirement as below:
There are data fields in the Excel File which are mandatory.When we are uploading the Excel file through webdynpro java it should validate the mandatory data fields are filled or not.Can anybody please send the required code or any related links.
Thanks,
Prakash.

Hi Surya,
As per my info, you need to upload the file first then only web dynpro will be able to check for the mandatory fields.
Do this, while reading the buffer from the excel, just check the size of desired columns. Hope that will help.

Guided Procedures - Integration of Webdynpro Java with Adobe Interactive fo

Hi All,
We have created Webdynpro java application with Adobe interactive forms.It works fine in NWDS and also in Webdynpro Content Administrator.
When we have called this component in Guided Procedures (callable object - Webdynpro (GP Interface)), the form screen has not displayed.
Plz help us..

Hi,
Scenario : User have to log into GP runtime, When he clicks the first action it should display the adobe form. He has to fill the details and submit the form. This form is routed for Approver 1 for review. The first approver will log into portal,view it (UWL),approve it and sent for second approver.The same process happens with the second approver.After both approvals, a BAPI updates the data in the interactive form in R/3
All the process have to be done in Guided Procedures, then integrated with Portal at the end.
We have tried creating an Wdynpro Java app with online adobe form and executed successfuly in NWDS and also in Webdynpro content administrator.
issue:-
When we create a callable object(webdynpro app(gp interface CO)) in GP and test, we were unable to view the form.
Now our question is : what are we mising ?
Is it possible to integrate online interactive adobe form with guided procedures?
Is our approach to solve the scenario right?
any links or tutorials will be greatly appreciated
TIA,

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,

I came across a better Webdynpro ABAP application which exactly fits the requirement but it is part of EHP5, getting a mini upgrade for one application was also rejected. is it possible to implement in a short period of time without great impact ..anybody experienced on this?
http://help.sap.com/erp2005_ehp_05/helpdata/EN/30/e67780e37f4f5a90105a9e9205660f/frameset.htm
So I am again back to finding way to enhance the weekly view.I read all teh therads...didnt find anyone successful
2. Default Attendance type & target hours & start & end times from Infotypes : CATS0002 exit is called only when we go to next step ,is there any other way to default as soon as CATS screen is loaded ?

Hi Suresh,
Thanks for your valuable inputs. I went and looked into the java file and found bit different.I dont see how they are getting the column headers like Saturday,Sunday,Monday...
Basically I need to keep one 'Submit' button on top of my table and on click, it should populate 8 hrs in the correspounding column.For eg. if its monday, it should default 8 hrs in monday column so that user dont have to manually type it in and also save these working hrs in the backend system without further click on 'Save' or 'Review'.
I still need to check with the ABAPers regading the user exit.
Also, Is it possible if I create a custom webdynpro application where I can use a BAPI that takes in the current day from my webdynpro and update the cats database and send an export parameter with success or error message.
Thanks

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

Table ui element in webdynpro java.

Hi Friends,
I am krishna i am working as sap webdynpro abap consultant . But right now i got the requirement on sap webdynpro java.
so please give me the required details.
Here are my questions.
1. how to populate the data into the table.
2. and the back end is erp, i have to use rfc. to display the data into the table .
3. so how to integrate the rfc into webdynpro java.
if u send with screen shots that would be very help for me.
Waiting for your reply.
Thanks & Regards.
Krishna.

It's very simple.
1) Import your RFC.
For this:
-Right click on Models->Create Model->Select Import Adaptaive RFC then follow the steps.
-Go to Used Models. Right click -> Add... -> then select the model that you created.
2) I guess you have a view that is using a controller (Custom/Component) so:
-Go to Context Tab-
-Create a model node.
-Bind the model node with the model that you created.
-Go to the view where you want to put the Table ui element and add the table (Outline window->right click->Insert Child->Table)
-Go to context tab, add a model node, en map it (Edit context mapping) with the model node that you created in the controller.
-Go back to layout tab. Then in table properties, in datasource click on the "..." and select the output node of the model that you have created in the view.
-Then in Outline Window-> Right click on the table element-> Create binding-> check the attributes that you want to be binded to the table.
-Then follow the steps.
You have now your table binded to the rfc.
Finally what you have to do is to create a method to execute the rfc. Usually it is written in the controller. Something like this:
public void execute<YourBapiName>( )
    //@@begin execute<YourBapiName>()
     IWDMessageManager manager = wdComponentAPI.getMessageManager();
     try
       wdContext.current<YourBapiName>Element().modelObject().execute();
       wdContext.node<YourBapiOutputNode>().invalidate();
       wdContext.current<YourBapiName>Element().modelObject().modelInstance().disconnectIfAlive();
     catch(WDDynamicRFCExecuteException e)
       manager.reportException(e.getMessage(), false);
    //@@end
To call this method, first, you have to bind the input parameters and then execute it (you can do this wherever you want):
<YourBapiName> input = new <YourBapiName>();
input.set<YourBapiParameters>(<YourParameter>);
wdContext.current<YourBapiName>Element.bind(input);
wdThis.wdGet<YourControllerName>(Controller().execute <YourBapiName>();
I hope it helps.
Bye bye.

How to export a Webdynpro java DC, for reuse in another system

Hi Everybody,
I am having a Webdynpro Java DC, i want to give that DC to another person to import into his system and work. i am doing a export of that DC and creating a zip file. But when we are trying to import it in another system, it is giving errors. When trying to build, its not showing DC options at all, DC-> buid or deploy options are not visible, when right clicked over the DC.
Am i doing it in a wrong way. Can anybody help me.
thanks & regards,
Ravi

Hi Ravi,
Are you working with local DC?
Then you can take ur dc in the following way..
Find where the dcs are stored in ur system..
<Some File Path> .dtc\LocalDevelopment\DCs\<your dc package>\
There will be a folder with your project name.
Copy that folder and Paste in the other system under the same folder structure.
ie., the copied folder need to be pasted here
<Some path> .dtc\LocalDevelopment\DCs\<your dc package>\
Once you copied,Open your NWDS and go to DC perspective.In the Local DCs.
Go to Local Development -- > My Component
Right Click on 'My Component' and click on 'Refresh'.
Your new project will appear under the 'My Component' hierarchy.
Right Click on your project and Choose 'Create Project'.
Now Proper dc will be available for you to work on.
If you are facing any problems, let me know.
Best Wishes

Problem with native offline Interactive Forms in webdynpro java.

I have a java webdynpro project build like the one in this tutorial:
http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/how-to-guides-rig-official/netweaver-2004/web-application-server/how%20to%20create%20online%20and%20offline%20forms%20in%20web%20dynpro%20(NW2004).pdf
The "Online" part of the tutorial is working but in the offline scenario I get no data in WebDynpro from the Interactive form (all of Context Attributes have a value "null") after the use of "Submit to SAP" button. this is the button from the Web Dynpro Native Library in the LC Designer.
the versioning information:
Netweaver 7.0 WAS on SP13
ADS SP13
Lifecycle designer 7.1
We updated the ZCI template according to the SAP notes.
Does anyone know this problem and how to fix it ?

Hi niru,
To work on adobe forms in webdynpro java you need to install ALCD(Adobe Life Cycle Designer) along with NWDS(NetWeaver Developer Studio).
To know about adobe forms in webdynpro check the following link
