Is my Web Dynpro currently running?

Hi
I'm sure there is a way to check whether an instance of wb dynpro is running but can't remember where I've seen it. Can someone remind me please?
I need to test whether a function call is to actioned if the web dynpro is in the call stack.
Cheers
Ian

Ah - found it!
cl_web_dynpro=>is_active
Check this to see if a WDA is running.

Where does Web Dynpro Abap run?

Hey,
I have a question concerning Web Dynpro Abap: The Portal runs on the AS Java. Web Dynpro Abap is encapsulated in iviews and integrated to the portal. The Abap Backend is linked to the portal via a system specification. As a Developer I do not have to care about the communication between the backend and the portal. Where does the abap web dynpro run? Probably on the linked AS Abap? What happens if the backend is down? Are my other assumptions right?

Hi,
Though Iam not familiar with Webdynpro java .
Netweaver WAS java is the runtime for Webdynpro Java.
A WDJ can consume SAP functions using adaptive RFC ,so obviously if a WDJ accesses a ABAP function and if the system is down,then a WDJ cannot consume it.
A WDA consumes the data directly from the ABAP system via native ABAP coding so mostly WDA is used for any ABAP based application.
WDJ is used within SAP to produce robust and highly scalable J2EE applications, such as the Employee Self Service (ESS) and Manager Self Service (MSS) and different SAP Portal applications like User and Role management transaction and Universal Work List (UWL).
For your question,consider , even during the initialization of WDJ ,if it tries to access a ABAP function module(but ABAP system is down),it will obviously result in error.
If only a particular button is triggered , WDJ consume a function module(ABAP system is down), I guess WDJ will appear in portal till the button is clicked.

ESS Web Dynpro Current month Payslip

Dear Expert,
I am not able to view my payslip for the current month even though i have run the payroll. For the rest of the month, i am able to view it but not for the current month.
I have run the payroll for august in the beginning of the month and expected to see the payslip in the ess. However it does not show in the portal. Are there any dates that can be change so that I can view the current month payslip.
Thanks
Regards,
Bryan

Hi Brian,
It works this way!
While configuring the HR backend system, with respect to your country coding(MOLGA).
You would have to keep in mind certain parameters like
Period Parameters
     The period parameter determines how often payroll is run for a payroll
     accounting area. Each payroll accounting area is assigned one period
     parameter. Payroll periods are defined for each period parameter.
     Examples of standard values are monthly, weekly, and bi-weekly.
Payday rule
    This field specifies how the payment date should be calculated for each
    payroll period.
Dependencies for Payday rule
    The field is used in connection with the Number of days field.
Number of Days
     In this field, you specify a value that the system uses in conjunction
     with the payday rule to determine the payday for every payroll period.
Determine Period Number
   In this field, you define which date of the payroll period the system
   uses to determine the Period Number. The system uses the period number
   in the Payroll Control Record to continually project the payroll period
   for a year. When counting the period numbers the system starts again at
   one with every fiscal year.
   Your entries then lead to different results, if the payday is outside
   the payroll period or if the start date and end date of the period are
   in different years.
Please ensure that all these values are checked against by your HR team.
Hope this helps.

NW2004s: Assigning a custom theme to a web dynpro running in the portal

The situation is as follows:
Some web-dynpros (for java) have a custom theme, a theme which is not the default theme of the portal or the default theme for web-dynpros in general.
In NW2004 this worked as follows:
When starting a web-dynpro in the portal it checked if it was started with the right theme. If not the exit plug of the WD interface view was called with an Url of the WD application plus a parameter for the right theme.
This is the famous parameter sap-cssurl.
For that parameter there are some values possible:
1) sap-cssurl=http://<host>:<port>/irj/portalapps/com.sap.portal.design.urdesigndata/themes/portal/mytheme
2) sap-cssurl=http://<host>:<port>/irj/portalapps/com.sap.portal.design.portaldesigndata/themes/portal/mytheme
3) sap-cssurl=http://<portal>:<host>/webdynpro/resources/sap.com/tcwddispwda/global/SSR/themes/mytheme
The first 2 are locations of the portal environment, the last one is a location of the WD runtime environment.
As I noticed this must be a full qualified absolute Url including host and port.
This works in NW2004 for web dynpro's running standalone AND in the portal.
Now for NW2004s:
The 3 variants of the parameter sap-cssurl work for web dynpro's running standalone.
But now for web dynpro's which are integrated in the portal:
The exit-plug with an Url is not possible anymore, this leads to the runtime error:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Exit-Plug must no be triggered with an URL when running in portal. Use portal navigation instead to navigate to another application!
Okay, as a first workaround I tried the portal navigation,
but somehow the supplied parameter sap-cssurl has no effect.
The code for that in the on-startup plug of the WD component:
WDPortalNavigation.navigateAbsolute(
PCD_ID,
WDPortalNavigationMode.SHOW_INPLACE,
null,
null,
WDPortalNavigationHistoryMode.NO_HISTORY,
null,
null,
"theme_set=X&" + theme,
 theme,
 false,
 true
I used there absolute portal navigation and the parameter (sap-cssurl=...) is part of the launcher parameter and the business parameter in the call to WDPortalNavigation.navigateAbsolute.
But as I wrote above, this has no effect on the theme.
In the I-View the parameter "Supply portal theme" is set to NO, otherwise the parameter "sap-cssurl" is supplied twice (this can be seen in the poroperties of the web-page in Internet Explorer).
What I tried afterwards was setting the parameter sap-cssurl hardcoded in the "Application parameters" of the I-View. This doesn't work either.
My question is: Should this be anyway possible for a NW2004s portal?
Did anyone successfully implement this?
Kind regards,
 Erich Lind

Hi Erich,
I am facing the same problem. I am on 04 s and couldnot implement the custom theme to a web dynpro running in the portal. When I run the web dynpro app as stand alone, the custom theme applies fine. But when in portal, it takes the standard theme.
Was wondering if you figured this out.
Thanks

How to catch URL parameter from Portal URL in Web Dynpro iView

Hi All,
I have a web dynpro application running as a portal iView successfully. Now the client wants to make it internationalized with 7 languages. Currently they access the portal - and via role assignment they get to the portal tab with the wd iView. Now they want to send a parameter for the language key with the portal URL. So when they are typing in http://myportal.mydomain.com now they want to type in http://myportal.mydomain.com?sap-locale=de or so. My question is how can I catch this parameter in the WD application when it is running inside a portal iView? Is it at all possible?
I have written a very small application which is trying to catch a URL parameter named PARAM. The code I have written is the default one as below:
String paramValue = WDWebContextAdapter.getWebContextAdapter().getRequestParameter("PARAM");
When I run the application standalone and add the PARAM=something in last of the URL I can catch it. But when I create an iView and while previewing it I add the same PARAM value it is coming as null all the time. Same when I add this iView to a role and show it via role assignment in protal. Please help to let me know how to achieve this. I think if I can read the parameter value from Portal URL in the WD iView - then I can set it as the default locale of the application and then show language specific file to achieve internationalization.
Your urgent help will be highly appreciated.
Warm Regards,
Shubho

Hi Shubhadip
Even if you get the parameters, how do you internationalize your application? Are you not following the standard way as described in the following link. In this case you never need to capture any such parameter. This is done by the WD runtime automatically .
<a href="http://help.sap.com/saphelp_erp2005/helpdata/en/f4/d95664da179b4db731e21c2e470b72/frameset.htm">Internationalization of WD projects</a>
You can retrieve application parameters specified at the creation of iview by "adding parameters(with the same name as in iview application parameters) to the default plug of the Component Interface View of the WD application". "onDefaultPlug" method of the interface view controller you get these values as parameters, which you can save in the context node of component controller for later use.This is guaranteed to work.
But again this is not what you want exactly. You want the user to specify the value at runtime. If you have just 7 languages, you can create 7 set of iviews with different application parameter value indicating language key, and assign to 7 different set of roles, each representing one set of users with common language.
I hope you find a solution.

ERP2004: ESS JCO session handling in Web Dynpro apps?

Hello,
we run ESS/MSS Web Dynpro scenarios, running on WAS 6.40, SP12 in
Enterprise Portal EP6 SP2 Patch 32. Our go live will be with > 1000 ESS users.
1. When will the sessions in R/3 backend system be terminated by the
Web Dynpro Application?
How is the session handling in FPM (Floor Plan Manager) implemented?
2. Are there any recommendations regarding the JCO connection settings
in Web Dynpro Content Administrator (Maximum Pool Size, Maximum Connections,
Connection Timeout, Maximum Wait Time) to reduce / optimize the load for the
backend system? I found a documentation in SDN but it is not
specific for ESS / MSS based on Web Dynpro.
Background of questions above: The customer is worry about the load on
SAP R/3 backend side: too much current users in the R/3 backend system,
possibly bad performance etc. because the JCO sessions are open a long time.
Are there any experiences with customers running productive ESS / MSS scenarios
based on Web Dynpro?
Thanks & Best regards,
Daniel

Hi,
1. For best practices on JCO settings follow the tutorial below and do it accordingly for your no of users. YOu might have to do some trial and error procedure.

Hi All ,
Can anyone please send me the Docs or link for Web Dynpro ABAP .
Thanks in advance
Rahul

Hi,
Web Dynpro ABAP
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/db22242d-0701-0010-28a2-aeaa1fefd706
Also, I have the official Web Dynpro for ABAP documentation. Please let me know if I should send it to you.
Hope that the following also helps you.
Web Dynpro for ABAP (WD4A, WDA) is the SAP standard UI technology for developing Web
applications in the ABAP environment. It consists of a runtime environment and a graphical
development environment with special Web Dynpro tools that are integrated in the ABAP
Workbench (SE80).
Web Dynpro offers the following advantages for application developers:
? The use of declarative and graphical tools significantly reduces the implementation
effort
? Web Dynpro supports a structured design process
? Strict separation between layout and business data
? Reuse and better maintainability by using components
? The layout and navigation is easily changed using the Web Dynpro tools
? Stateful applications are supported that is, if the page is changed and the required
data remains intact so that you can access it at any time throughout the entire
application context.
Note that stateless applications are not possible.
? Automatic data transport using data binding
? Automatic input check
? Automatic operation of the Web Dynpro application using the keyboard
? User interface accessibility is supported
? Full integration in the reliable ABAP development environment
Web Dynpro Architecture
Definition
Web Dynpro is the SAP NetWeaver programming model for user interfaces (UIs).
The Web Dynpro model is based on the Model View Controller paradigm, and has the
following features that build on the classic dynpro model:
? Clear separation of business logic and display logic
? Uniform metamodel for all types of user interfaces
? Execution on a number of client platforms.
? Extensive platform independence of interfaces
Structure
Metamodel Concept
Web Dynpro provides support for developing Web representation of a business application.
You use specific tools to describe the properties of a Web Dynpro application in the form of
Web Dynpro metadata. The necessary source code is then generated automatically and
executed at runtime. In addition to the events offered by the framework, you can also define
your own events for a Web Dynpro application. However, the event handling must always be
programmed in separate source code areas which are executed automatically when the event
is triggered at runtime.
In Web Dynpro, each user interface is always made up of the same basic elements. These
elements of the metamodel can be statically declared using Web Dynpro tools.
It is also possible to implement elements of the metamodel at runtime and to change them or
reintegrate them at runtime. Using these implementations, you can make any changes or
enhancements to a user interface that has been created by declarative methods by
generating new interface structures at runtime.
This means that you can combine declarative processes and the implementation of source
code.
Graphical Development Tools
To support this declarative concept, both the SAP NetWeaver Developer Studio and the
ABAP Workbench contain a range of Web Dynpro tools. You can therefore generate a large
proportion of a Web Dynpro application using the tools provided, without having to create your
own source code. This applies to the following parts of the application:
? Data flow between the front end and back end
? Layout of the user interface
? Properties of user interface elements
The Web Dynpro tools enable you to create source text areas manually within generated
source texts. These areas are not changed if the source code is regenerated.
Separation of Business and Application Logic
Using Web Dynpro enables a clear separation of business logic and display logic. A Web
Dynpro application runs on the front end and has local or remote access to the back end
system via a service. This means that the display logic is contained in the Web Dynpro
application, while the business logic and the persistence of the business objects run in the
back end system. The following options are currently available for connecting Web Dynpro
applications and the back-end system:
? An interface generated using adaptive RFC, through which BAPIs of an SAP system
can be called
? An interface for calling Web services
? A self-generated interface
The source code required for connecting the Web Dynpro application can be generated
from a UML definition of the Web Dynpro interface. A UML definition can be imported
into the Web Dynpro tools as an XML file.
Conversion of the Model-View-Controller
Conversion of the Model-View-Controller Programming Model
Every Web Dynpro application is structured according to the Model View Controller
programming model:
? The model forms the interface to the back end system and thus enables the
Web Dynpro application access to data.
? The view is responsible for the representation of the data in the browser.
? The controller lies between the view and the model. The controller formats
the model data to be displayed in the view, processes the user entries made by the
user, and returns them to the model.

Web dynpro URL not working in user's UWL

Hi,
I am not sure if this is the right place for this question. I have created a web dynpro application and copied the URL and we put this URL in the UWL of a user using workflow, now the issue is when a user click on that URL on the portal side it's not doing anything but when I go r/3 side and click on the URL in my inbox I can see my web dynpro application running.
Any idea why is this happening.

System.getProperties().put("proxySet", "true");
System.getProperties().put("proxyHost", <HTTP Proxy Host> );
System.getProperties().put("proxyPort", <HTTP Proxy Port> );
InputStream is = u.openStream();
DataInputStream dis = new DataInputStream(new BufferedInputStream(is));
You can check the proxy settings in System Administration - >System Configuration -> Service Configuration -> Applciations ->com.sap.portal.ivs.httpservice -> Services -proxy.

Notification Service in Web Dynpro for Java?

Hello Experts,
I'm new on the topic "web dynpro for java" and have a question about a real-time-notification of web dynpro clients.
In web dynpro for abap ther is apparently a new solution called "Notification Service" (since NW 7.0 Ehp2).
Details: http://www.sdn.sap.com/irj/scn/elearn?rid=/library/uuid/f0802995-3433-2c10-2787-d7db51352891&overridelayout=true
But I found no hints how to solve the problem of a real-time notification in web dynpro for java.
Requirements for short: The server can trigger a refresh in one or more web dynpro clients.
Requirements a liitle more extended:
1. A web dynpro is running in a browser and shows data it gets from a DataBase table1
2. Now a function module1 is started by an event and changes the data in table1 on the server side, the web dynpro does not know about this event or the changes made by external components.
3. These changed data should be visible immediately in the running web dynpro after the event occurd --> trigger a refresh of the web dynpro from the function module1?
All I actually know is that: The web dynpro can update its context with the new data from table1 after a refresh of the gui (wddomodifiyview). Using a timed trigger I can get new data after x seconds (same way --> context update and gui refresh). Is there another way to refresh the web dynpro (that noticed requirements of #3) ?
Regards,
Anja Hormann

I recommend that you create another Web Dynpro application with this Timer to execute an RFC. This application would be in a Web Dynpro iView hidden from your SAP EP and shoot an event that would be captured by another application.
However I would take great care with this type of application.
And to answer your question at the moment, to my knowledge, there is no solution for this kind of integration between the ABAP and JAVA.

Angelo

How to display RFC-Logon-Screen for non trusted connection in Web-Dynpro?

Dear Web-Dynpro-Specialists,
i got a issue while creation of an WebDynpro-Tool, which is using RFC connections for reading data.
In some cases the RFC connection is not a trusted one connection, so a login is nessessary, but in
this cases not a window is coming up for login....
Any idea how i can get this window for login, in order to collect the nessessary Data for my tool?
Additional Information concerning the RFC connection:
While running my Web-Dynpro i run this Method:
METHOD get_table_entries.
CLEAR rt_entries[].
CALL FUNCTION 'RFC_GET_TABLE_ENTRIES'
DESTINATION iv_destination
EXPORTING
gen_key = iv_table_key
table_name = iv_table_name

WHEN 3.
RAISE table_not_found.
WHEN 4.
RAISE unknown_error.
ENDCASE.
ENDMETHOD.
Thanks a lot in advance

Hi!
You can use the function module RFC_MODIFY_R3_DESTINATION to create, modify and delete RFC connections. You will need the system ID (e.g. ABC), client (e.g. 123), system number (e.g. 00) and the host name of the server. In this example the following code would create or modify the RFC destination ZRFC_DESTINATION.
    CALL FUNCTION 'RFC_MODIFY_R3_DESTINATION'
      EXPORTING
        destination                = 'ZRFC_DESTINATION'
        action                     = 'M'
        systemid                   = 'ABC'
        systemnr                   = '00'
        server                     = 'serverhostname'
        language                   = sy-langu
        client                     = '123'
        user                       = 'USERNAME'
        password                   = 'PASSWORD'
        description                = 'Dummy RFC Connection'
      EXCEPTIONS
        authority_not_available    = 1
        destination_already_exist = 2
        destination_not_exist      = 3
        destination_enqueue_reject = 4
        information_failure        = 5
        trfc_entry_invalid         = 6
        internal_failure           = 7
        snc_information_failure    = 8
        snc_internal_failure       = 9
        destination_is_locked      = 10
        OTHERS                     = 11.
With the following code you can delete this connection:
    CALL FUNCTION 'RFC_MODIFY_R3_DESTINATION'
      EXPORTING
        destination                = 'ZRFC_DESTINATION'
        action                     = 'D'
      EXCEPTIONS
        authority_not_available    = 1
        destination_already_exist = 2
        destination_not_exist      = 3
        destination_enqueue_reject = 4
        information_failure        = 5
        trfc_entry_invalid         = 6
        internal_failure           = 7
        snc_information_failure    = 8
        snc_internal_failure       = 9
        destination_is_locked      = 10
        OTHERS                     = 11.
Please keep in mind that deleting an RFC connection is usually noted in the system log.
If you want to reuse your connection for multiple servers, you could run into trouble since connection data is cached.
Sincerely,
Stefan

Push data/ trigger event in Web Dynpro app

Hello All.
I'm a newbie with web dynpro. I have a need to push information to a web dynpro application. Is there a way I can trigger an event in web dynpro to refresh the screen from another application running on the Netweaver J2EE? Is it possible to implement an ActiveX or AJAX application to retrieve server data and communicate with a web dynpro app running on the enterprise portal?
Your help will be appreciated.

Web Dynpro resets connection when calling webservice

Hi,
I get a very very strange problem by using Web Dynpro to implement a webservice client.
The Webservice provider is running on a IBM WebSphere Server. I can use xmlspy to call this service and get the response correctly as expected.
But when my web dynpro application (running on WebAS 6.40 Stack 13) calls this webservice, I only get incomplete SOAP response message. It looks like the HTTP response had been broken beforte it finished. To verify this, I use ethereal to analyse the tcp packet. And I find that the WebAS server has sent some tcp reset packets to the websphere server, before the http response can be finished. This problem can be reproduced on different WebAS server. So it can'b be caused by hardware defect.
When I use web dynpro client to call other webservice on other WebAS server, there is no problem at all.
I have really no idea, how could this happen.
Thanks in advance.
Kanyin

Hi,
Now we know how it happens.
The reason is the content of the soap message from webservice provider is by means of the WSDL definition not complete, although the message structure is complete.
The Web Dynpro deserialise the soap response on the fly, without getting the complete SOAP message first. When the parser throws any exception, the connection will be broken by the WebAS.

Hi,
Web Dynpro is the SAP programming model for user interfaces (UIs).
It provides a programming framework within which you can achieve a:
u2022 Clear separation of business logic and display logic
u2022 An application specification that is both:
Client neutral and
Backend neutral
It consists of a runtime environment and a graphical development environment with special Web-Dynpro tools that are integrated in the SAP NetWeaver Developer Studio
The Web Dynpro technology provides a development and runtime environment for Web applications and enhances classical Web development to build easily adaptable user interfaces. SAP's Web Dyn-pro technology closes significant gaps between typical Web development tools and the needs of cost-effective, responsive, easy-to-use, maintainable, and professional browser-based user interfaces for business solutions. Web Dynpro uses design principles similar to SAP's Dynpro technology, but it is a completely new technology geared exclusively towards Web applications. Its main features include the following:
u2022 Usability
u2022 Abstract modelling
u2022 Personalization and customization
u2022 Separation of presentation layers and business logic
u2022 Generic services
u2022 Portability
Web Dynpro applications run in the SAP Enterprise Portal.
