Add html code in web dynpro application

Hi
Is there a method to add HTML Code in web dynpro application so that it works same as HTML works in browser
I have to add a clock in my application How can i do that
Best regards
Suresh

If you're on NetWeaver CE or otherwise use Wb Dynpro for Java 7.2 or higher, you could use the WebWidget control, see http://help.sap.com/saphelp_nw73/helpdata/en/49/bfa3b2e55657bae10000000a42189d/frameset.htm
Otherwise, I'm afraid your only option is to use an IWDIframe component in your WDJ project, embedding the HTML.. Be carefulo though, the IWDIframe component is deprecated (since each server roundtrip forced a reload of the IFrame it was pretty useless)
Hope this helps!

Display HTML stream in Web Dynpro application

Hello,
Sorry, I am new to the Web Dynpro environment, so this might seem like a stupid question.
How can I display streaming HTML content in a Web Dynpro application. The IFrame element only seems to allow you to point to a URL. In this case, I am receiving an HTML stream back from an R/3 system via a BAPI call.
Thanks very much.

Hi
As per your question, I understand that HTML output is getting generated through a R3- Bapi call. Fine, create a model with the data binding to the context to some text view. Simply create view with the relevant UI element through which you want to exhibit the data and call the R3 call through your model. instead of a HTML output, you will get your data in the view.
you may not get the exact format / style of the html output.
Otherwise, directly HTML content cannot be shown in webdynpro. You need to have some UI control to take its content.
Or else, you can go in for j2ee stack and end up with a java based appl, use a simple jsp and get the output!
if you have any specific queries do let us know
hope this helps you
thanks

Source code for "Creating an Extended Web Dynpro Application"?

Hello!
I'm a rookie in the field of SAP Netweaver and I'm justing getting started with some tutorials. My problems with "Creating an Extended Web Dynpro Application" are to massive to be posted on this forum in this stage. What I want to have some help with is to find the source code for that tutorial so I can get som guidence from there.
Following text is cut out of this page:
http://help.sap.com/saphelp_nw70/helpdata/EN/5d/f42fef2eec724597a03b6bcc670c2c/frameset.htm
Creating an Extended Web Dynpro Application
You can download the Web Dynpro project for the current tutorial from the Software Developer Network SDN (http://sdn.sap.com -> Web Application Server -> Web Dynpro -> Sample Applications and Tutorials) in two versions: one skeleton version you can use for exercises and one final version (solution) for an immediate build, deployment and run on the Java engine of the SAP Web Application Server.
How hard I try I can't find the specific source code on sdn.sap.com
Does anyone have a clue where it is?
Thanks!

Hi!
I did what you said but I seem to miss the IDE folder. This is what it looks in my Explorer
C: > Program Files > SAP > IDE > CE > eclipse > (no folder called "examples")
I also did a search in this eclipse folder for "examples" but I did'nt find the example I'm looking for
I am running a newer version of NWDS:
SAP NetWeaver Developer Studio
SAP NetWeaver 7.1 Composition Environment SP03 PAT0000
Maybe that's why things don't look the same?

How to get User Id in Web dynpro application

Hi Experts,
I am running web dynpro application with authentication checkbox set. I want to display user id of the user in my application. I am using following code in Init method of component controller.
IWDClientUser wdUser = WDClientUser.getCurrentUser();
WdContext.currentContextElement().setUserName           (wdUser.getClientUserID());
Here I am getting some integer value as userId.
I am not using Portals, so solutions suggested for portal are not useful for me .
Is there any way to get this uset id.
Thanks in advance

hi
try this piece of code
          IWDClientUser wdUser = WDClientUser.getCurrentUser();
          IUser user = wdUser.getSAPUser();
          if (user != null)
                    IUserAccount[] acct = user.getUserAccounts();
                    if(acct[0] != null)
                              String strUserid = acct[0].getLogonUid();
wdContext.currentZtms_Fm_Regupdate_InputElement().setAssoid(new String(strUserid));
Note: Defining the IUser will show an error. To resolve this, within the properties of
the project, choose Java build path -> Libraries -> Add external jars ->
com.sap.securities -> lib -> com.sap.security.api. Open this file and retype the code.

Using a Deployable Proxy in a Web Dynpro Application

Hi,
We have a Web Dynrpo application whose model is built from a set of Java business objects (POJOs.) These Java business objects currently make calls to a back-end R/3 system using JCo. We would like to provide the ability to allow the calls to be made over Web Services to the back-end system.
To call the RFMs as web services we have created a Deployable Proxy project, added the proxy as a public part, then referenced that public part in the web dynpro application. At this point we can write code to call the web service that looks something like:
InitialContext ctx = new InitialContext();
Object serviceObject = ctx.lookup("wsclients/proxies/meridium.com/rcmo~proxies/com.meridium.rcmo.ws.proxies.plants.PlantProxy");
Z_MRDM_GET_PLANTSService service = (Z_MRDM_GET_PLANTSService)ctx.lookup("wsclients/proxies/meridium.com/rcmo~proxies/com.meridium.rcmo.ws.proxies.plants.PlantProxy");
Z_MRDM_GET_PLANTSPortType port = service.getLogicalPort();
Z_MRDM_GET_PLANTS plantParameter = new Z_MRDM_GET_PLANTS();
plantParameter.setI_PLANTID(id);
plantParameter.setI_PLANTNAME(name);
Z_MRDM_GET_PLANTSResponse response = port.z_MRDM_GET_PLANTS(plantParameter);
MT001W[] plantArray = response.getET_PLANTS();
The problem is that when I call looup to retrieve the service implementation I get a ClassCastException.
The tutorials for using a proxy in web dynpro all assume that the web service is what the model is based upon but that's not possbile for our scenario we need to call the proxy from the business objects which are the basis for our model.
According to the help documentation for consuming a deployable proxy in a JSP page:
<a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/2d/b9766df88f4a24967dae38cb672fe1/frameset.htm">http://help.sap.com/saphelp_nw2004s/helpdata/en/2d/b9766df88f4a24967dae38cb672fe1/frameset.htm</a>
It discusses adding JNDI mappings. Is this what's needed for the reference to work in a Web Dypro application too? If so, how would one add the JNDI mappings references to a Web Dynpro application?
Many thanks!

Hi Dheeram,
I'm not certain about JSPDynpage specifically, but in a general J2EE Enterprise Application project you can add a reference to the application-j2ee-engine.xml file. For example here's the content of an application-j2ee-engine.xml file that references a proxy:

Web Dynpro application needs to never expire.

Hi
I have a Web Dynpro application (NW2004 SP12) that displays spreadsheet like sales data to anyone who walks past the screen in a common area in the office/s. It should therefore run unattended. It refreshes the data on a timer. The data comes from a back-end aRFC. Everything works fine but about every 1.5 days the application times out (session expires) and needs to be re-opened (this seems to be a large administrative problem to re-login at all the deployment sites).
It gives an error 500application has expired. Please restart with the refresh button
In testing/troubleshooting I used the direct URL to the application running on WAS and not through a Portal iView.
I also changed the System destination from using SSO to using a dedicated user to the back-end.
Does anyone have an idea on how to auto refresh a Web Dynpro application or auto-renew the session so that it can run forever or a way to re-login automatically?
Thanks in advance,
Rick Viljoen

Hi Isidro
Yes, this was my final solution. Here is the code for the htm page. It will refresh/reload every 6 hours. Hope it helps.

Value hep problem in web dynpro application

Hi All,
I have a requirement where I need to add a field for alternate payee to the web dynpro application and the field name is BSEG-EMPFB. I have written the following code to get the values of it based on the vendor number:
SELECT SINGLE * FROM lfb1 INTO f4lfb1_z
                  WHERE lifnr = lv_lifnr
                  AND   bukrs = '001'."bseg-bukrs'.
CALL FUNCTION 'FI_VENDOR_ALTERN_PAYERS_READ'
    EXPORTING
      i_lifnr            = lv_lifnr
      i_filkd            = filkd
      i_bukrs            = '001'
      i_lfb1_head_office = f4lfb1_z
    TABLES
      t_zemtab           = t_zemtab.
LOOP AT t_zemtab INTO w_zemtab.
    ls_value_set-text = w_zemtab-empfb.
    ls_value_set-value = w_zemtab-empfb.
append ls_value_set to lt_value_set.
DATA lo_nd_alt_payee_info TYPE REF TO if_wd_context_node_info.
DATA lo_nd_alt_payee TYPE REF TO if_wd_context_node.
lo_nd_alt_payee = wd_context->get_child_node( name = wd_this->wdctx_alt_payee ).
lo_nd_alt_payee_info = lo_nd_alt_payee->get_node_info( ).
         lo_nd_alt_payee_info->set_attribute_value_set(
            name = `ALTERNATE_PAYEE`
            value_set = lt_value_set )
Now the problem is user wants the details of the alternate payee as F4 help and when I debugged the standard FV60 functionality this how the F4 help is being build therE:
REFRESH fldtab.
CLEAR fldtab.
fldtab-tabname    = 'IZEMTAB'.
fldtab-fieldname = 'EMPFB'.
fldtab-selectflag = 'X'.
APPEND fldtab.
CLEAR fldtab.
fldtab-tabname    = 'IZEMTAB'.
fldtab-fieldname = 'NAME1'.
APPEND fldtab.
CLEAR fldtab.
fldtab-tabname    = 'IZEMTAB'.
fldtab-fieldname = 'ORT01'.
APPEND fldtab.
CLEAR fldtab.
fldtab-tabname    = 'IZEMTAB'.
fldtab-fieldname = 'STRAS'.
APPEND fldtab.
*------- Fill Values for Function Module Call --------------------------
REFRESH valtab.
LOOP AT zemtab.
    valtab-feld = zemtab-empfb.
    APPEND valtab.
    valtab-feld = zemtab-name1.
    APPEND valtab.
    valtab-feld = zemtab-ort01.
    APPEND valtab.
    IF zemtab-stras NE space.
      valtab-feld = zemtab-stras.
    ELSEIF zemtab-pfach NE space.
      CONCATENATE 'Postfach:'(019) zemtab-pfach INTO valtab-feld.
    ELSE.
      valtab-feld = space.
    ENDIF.
    APPEND valtab.
ENDLOOP.
*------- F4 Dialog -----------------------------------------------------
CALL FUNCTION 'HELP_VALUES_GET_WITH_TABLE'
    EXPORTING
      display      = space
      fieldname    = 'EMPFB'
      tabname      = 'INVFO'
    IMPORTING
      select_value = empfb
    TABLES
      fields       = fldtab
      valuetab     = valtab.
IF NOT empfb IS INITIAL.
    invfo-empfb = empfb.
ENDIF.
can you please tell me how can I accomdate this in the web dynpro application?

Hi Raja,
Search help is availble at dictinary level you get F4 help automatically.
Otherwise create OVS help for alternate payee. use WDR_OVS.
check this..

Using EJBs in Web Dynpro Applications

I have recently started to develop Web applications using the Web Dynpro framework. Coming from a pure J2EE world, I must admit that Web Dynpro has a few innovative features that I find interesting for user interface development. The use of component & view contexts, for example, is not unlike the ActionForms that one may find in a Struts application, but pushed a bit further. No complaints here.
What I do have some problems with is the whole CommandBean paradigm that is put forth by SAP (refer to the document <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webdynpro/using%20ejbs%20in%20web%20dynpro%20applications.pdf">Using EJBs in Web Dynpro Applications</a>).
I do understand the usefulness of defining a model that will be used to generate and eventually bind to Context data structures. That's fine. What I do object to is the use of a so-called CommandBean to play that role. Again, coming from a J2EE world, I am familiar with the BusinessDelegate pattern - which would typically be used by a client application to invoke business logic on the server side. I would propose that a better, cleaner way of integrating EJBs with the Web Dynpro framework would be to use a BusinessDelegate for invoking business logic, and importing a separate and distinct ModelBean (instead of a CommandBean) to be used for defining and binding to Context data.
I have built one Web Dynpro application thus far. Instead of using a CommandBean, I created a ModelBean that extends my business object DTO (Data Transfer Object) (which is quite appropriate for that role, given that it implements all the get & set methods that are required for the business data that I need to model). My Web Dynpro application also makes use of an independant BusinessDelegate that is packaged with my EJB DC - this is a standard best practice on J2EE projects. I have been asked by the people working with me to modify this architecture to bring it more in line with the SAP way of doing things. I am open-minded and willing to learn and accept new ways of thinking and doing things. However, I fail to understand the usefulness of merging structure and behaviour by resorting to CommandBeans:
- <b>It violates the MVC paradigm</b> by having one object (the CommandBean) serve as both model AND controller as far as the Web Dynpro application is concerned. The CommandBean is obviously a model - since it is literally imported as such into the Web Dynpro application. It is ALSO a controller from the Web Dynpro's application perspective, since all calls to the back-end go thru the CommandBean via one or more of its execute_xxx methods. In contrast, the use of a business delegate by the Web Dynpro application clearly separates the model (the CommandBean... or rather, a more suitably named ModelBean) from the controller (BusinessDelegate).
- <b>Doesn't carry its own weight</b>. In other words, I haven't yet been provided with any valid justification for going thru the extra effort of coding the CommandBean's execute methods. It's been proposed to me that it somehow serves as an abstraction layer between the Web Dynpro application and the business logic. I would argue that it is the BusinessDelegate's role to abstract away the back-end logic from clients. If one does have a BusinessDelegate available, I would argue there's no need to code execute methods in a separate CommandBean. To prove my point, I would simply point out that all of the CommandBean examples that I have seen so far, either in How-To documents, or in production code, all follow the same pattern....
CommandBean.execute_doSomething() calls BusinessDelegate.doSomething()
Not a heck of an "abstraction" layer... I would in fact argue that it is worse than useless. If some major change occurs in the business logic that requires changing the doSomething() operation, we expect of course to modify the BusinessDelegate. The Web Dynpro client will also presumably need to be modified - that's to be expected, and unavoidable. But then, we'll also need to go about and change the CommandBean's execute_doSomething() method - again, extra work for no apparent benefit. Adding and removing business methods has the same implication. All this for an layer that simply adds the prefix execute_ in front of all business method calls... Is this "abstraction layer" worth the cost of creating and maintaining it ??
- <b>Unnecessarily complicates error handling</b>. I have been told that for technical reasons, it is recommended that all exceptions thrown by the CommandBean be of type WDException or WDRuntimException. But what if the client application needs to react differently to different failure scenarios ? When I create a business object, I might wish to provide the user with an error messages if connection is lost to the backend, and with a different error message if an object already exists in the database with the same attributes. In order to do that, I will have to catch the WDException, extract the cause, and continue processing from there... possible, yes, but clearly less standard and more labor intensive than the classical try/catch mechanism.
To say nothing about the fact that SAP's own API documentation clearly states that applications using Web Dynpro can reference and catch WDExceptions, but THEY MUST NOT THROW OR EXTEND IT !
- <b>Produces unnecessary DCs</b>. Page 6 of the aforementioned document presents an architectural view of a Web Dynpro project that uses a CommandBean. Why an extra DC for the CommandBean ?? I created my ModelBean class right inside the Web Dynpro project (in the Package view). That, to me, is where this class should reside, because it is created for no other reason that to be used by this particular Web Dynpro application. What is the benefit of placing it in its own independant DC ?
- <b>Not a typical application of the Command pattern</b>. The well-documented command pattern (Design Patterns - Gang of Four) has been devised mainly to enable encapsulation of request as objects, thereby making it possible to:
- specify, queue and execute requests at different times
- decouple execution of a command from its invoker
- support undo operations
- support logging changes so that they can be reapplied in case of system crash making it possible to assemble commands into composite commands (macros), thereby structuring a system around high-level operations built on primitive operations.
None of this applies to the way the SAP CommandBeans are being used. Not that much of an issue to people new to J2EE and/or OO development... but quite confusing for those already familiar with the classic Command pattern.
At this point, I fail to understand the advantage of merging structure (model) and behaviour (execute methods) through the use of a unique CommandBean object. Am I missing something ?

Hi Romeo,
You would be disappointed, this reply ain't anywhere nearby to what you are talking about...
I wanted to mail you, but you have not mentioned your email in your profile.
I am really impressed by your flair for writing. It would be far better had you written a blog on this topic. Believe me, it would really be better. There is a much wider audience waiting out there to read your views rather than on the forums. This is what I believe. To top it, you would be rewarded for writing something like this from SDN. On the blogs too, people can comment and all, difference being there you would be rewarded by SDN, here people who reply to you would be rewarded by you. Doesn't make much a difference.
Anyways the ball is still in your court
As far as I am concerned, it has still not been much time since I have started working on Web Dynpro. So can't really comment on the issue...

Problem deploying Web Dynpro Application Definition

Hi,
I have written a Web Dynpro and then deployed it to an EP6 NW04 server without first defining the Web Dynpro Application (silly me, I know - how could I do such a thing?). Anyway, afterwards, I created the Web Dynpro Application definition, but no matter how many times I redeploy, it does not add it to the Web Dynpro now sitting on the server.
Können Sie mir bitte helfen?
Martin

Hi
Martin,
Although server is being maintained by third part(one option is though visual admin since you can't access it) other option is use youe web browser with url http://your server IP address:50000/index.html u will find webdynpro link as mentioned below
<b><u>Web Dynpro</u></b>
Web Dynpro is a User Interface technology available within the SAP NetWeaver Developer Studio.
Various Web Dynpro tools provide administrators and application developers with performance measurement and application administration capabilities. The Web Dynpro runtime is already deployed.
Now Click on <b><u>Web Dynpro </u></b> link
you will find Content administrato and web Dynpro administrator u will b directed to login page after entering with UID and passwd u can see all deployed applications ( u can check ur application) and details...
I hope this may help u..

Problem while navigating the different portal Web Dynpro application

Hi .
while navigating from one application to another.
my IE browser stuck with the error.
Can't execute the code from the freed script.
it occurs:
when i navigate from tree structure 's child to another web dynpro application.
what to do ...
Regards

Hi John,
How have you added the required jar files. For DC projects you cannot use project properties and add the jar files to the build path (In case you have followed this method).
You will have to add the public part (i believe it is ejbclient.jar and is generated automatically when you create an EJB DC) of the EJB DC as used dc.

Hi Siva,
to my understanding - your problem has nothing to do with J2EE server configuration - your application is already deployed on the server and running (brings error though):
at com.sap.examples.welcome.wdp.InternalStartView.<init>(InternalStartView.java:43)
so your class is already called.
DC = Development Component, but if you created a "simple" WebDynpro project - you should read the hint as "are you sure your project is properly deployed?"
I got similar messages (see your quota about NoSuchMethodException - I'm not really sure I was getting NSME, but definitely "Failed to create delegate for view") in case a Java-type context attribute was not initialized (e.g. you create context attribute of type java.util.Properties, do not put any object there, and request the attribute value). Check if you properly initialize context attributes.
Another thing - I presume you're running DevStudio of the same version as your server. DevStudios of different versions generates different sources - there could be problems in run-time when out of synchronization.
Best regards,
Nick

Error while accesing ABAP web dynpro application

Hi Experts,
We are getting warning symbol on web page status bar, when we are accessing the ABAP web dynpro application
only first page of application is getting loaded and when we click on page it is showing error on status bar and we can perform any thing.
once we double click on warning icon,
below details are coming:
Line: 1491
Char: 3
Error: Object Expected
Code: 0
URL: url of the ABAP web dynpro application
This scenario is occuring for many ABAP WD application for a client.
Please guide how to solve this issue?
Thanks!
Piyush

Hi
First try a very simple application with nothing in it just one text saying Hello World
Run it and see what happens.
Also check if your url uses FQDN name. something like https:
company.name.co:50000\.......
If you do not use the FQDN it will always show a script error on the bottom and some functions will not work e.g
dropdowns.

Yuval.

Error while implementing a web service in web dynpro application

HI All,
I am trying to use a webservice in a web dynpro application.
Web service description:- This is a very simple application which takes two String inputs and when submitted displays the string in the concatenated form.
Web dynpro:- I used this web service in the web dynpro as an adaptive web service model.
The Layout design consists of two input fields which are mapped to the request fields
ex : - Request_Add.Add.S1 and Request_Add.Add.S2
A text area to display the response:- Request_Add.Response.AddResponse.Response
And a button which invokes the execute method
public void onActionWebserviceCall(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionWebserviceCall(ServerEvent)
    wdThis.wdGetWebserviceCompController().executeRequest_Add();
    //@@end
When I am trying to run the application I am getting error:-
Exception on execution of web service with WSDL URL 'http://<Host>:<Port>/EjbWebservice/Config1?wsdl' with operation 'add' in interface 'EjbWebserviceVi_Document'
Kindly reply.
Thanks
Neha

Hi,
Yes I have tested the web service in Navigator . The WSDL is also properly generated.
I have not publish the web service in UDDI but as per my understanding this is not necessary. please correct me if I am wrong.
Thanks

Cannot deploy web dynpro applications

Hello,
I'm starting to develop web dynpro applications, and I can run them on the nwds, but I cannot deploy them to the SDM, i always get the following error:
/userOut/deploy (com.sap.ide.eclipse.sdm.threading.DeployThreadManager) [Thread[Deploy Thread,5,main]] ERROR:
[003]Deployment aborted
Settings
SDM host : myserver

Deployment exception : Server myserver did not accept login request as admin on port 50118. Details: ERROR: Could not establish connection to server myserver at port 50118: No route to host: connect
Inner exception was :
Server myserver did not accept login request as admin on port 50118. Details: ERROR: Could not establish connection to server myserver at port 50118: No route to host: connect
I have installed Sneak Preview SAP NetWeaver 2004S SR 1, i can access the enterprise portal with no problems.
I would be appreciate if anybody could help me with this issue.
Regards,
Leandro Fonseca

At the same time if more users are deploying then you may such 'deployment aborted' errors check if there are more child instances for the J2EE engine.If not ask your basis administrator to create more child nodes to balance the load on the server instance.Also You can find out the server details at
"http:
<hostname:portnum>\index.html"select system configuration-you can get the details of the SDM and the j2ee engine from there.You need to have proper credentials to get the information from the above url.
Provide those details in the NWDS.

How to get Portal User Context in Web Dynpro application

I have successfully integrate a web dynpro app into SAP Netweaver Portal.
Within my web dynpro app, how can I get portal user context information such as first name, last name, job title or some newly created ume attibutes.
Is there any programmatical approach to get portal user context in my web dynpro. I not sure whether I can use the following codes in web dynpro?
IUserContext userContext = request.getUser();
String firstName = userContext.getFirstName();
String lastName = userContext.getLastName();
If yes, can someone point me the name of the jar file I have to import.
Note : The SAP Netweaver installation that runs my web dynpro app is same with the SAP Portal.

Hi ,
you can use the below code to get User details and add com.sap.security_2.0.0 > lib > com.sap.security.api.jar
try
IWDClientUser clientUser = WDClientUser.getCurrentUser();
String firstName = clientUser.getFirstName();
String lastname = clientUser.getLastName();
catch (WDUMException e) {
wdComponentAPI.getMessageManager().reportException("Error Retrieving User"+e.toString(),true);
