Can I use web Dynpro to access other database

Hi Experts,
Can I use web Dynpro to access other database? Like we have a Siebel Database, can web dynpro application read data from there? If yes, How can I do it?
Thanks a lot!!!

Hi,
I think you should be able to write Native SQL in the supply function or the methods of the Assistance Class.
Hope this helps.

ABAP Web Dynpro V/S JAVA Web Dynpro

We need to pick developing technology between ABAP Web Dynpro v/s JAVA Web Dynpro. Is technology better than other in terms of security, scalability? There is lot of documentation on the web but it is very old and out dated. I am pretty sure things have changed quite a bit with recent versions of SAP. Any feedback is greatly appreciated.
Thanks.
PS: I Used Web Dynpro for ABAP at my previous client for SAP SRM without a problem.

Dear Sap Fan
This has been a long and interesting debate on SDN.
You will find plenty of posts discussing this matter.
But there's no clear winner, I warn you.
;o)
This one in particular is very good:
[http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/e0e4940c-035c-2b10-0b9d-eb8f99674f4e]
But you can also check these others:
[webdynpro java or abap;
[Webdynpro Java or ABAP;
[Webdynpro Java or ABAP;
[Webdynpro Java or Abap ?;
More and more you see clients migrating from WD4J to WD4A.
Guess SAP is also heading into that direction, perhaps because Oracle bought SUN sometime ago.
I'm comfortable on both environments I have to say.
I have more than 10 years with development.
I know ABAP from inside out.
I also know JAVA and I'm certified with this technology.
But I personally prefer WD4A.
Why ?
Because you don't need to use NWDI.
Because you don't need to configure JCO's.
Because you integrate seamlessly the development with the transport framework (requests, etc..)
Because debugging is great.
Because plenty of traditional ABAP tools (trace, logs, performance analysers, etc..) can also be used with WD4A
Because you don't need to worry with NWDS...just type SE80 and you're there... ;o)
And I could go on and on....
But then again, it all depends:
Do you have a lot of good in-house JAVA knowledge ?
Do you use a lof of Custom JAVA development in your company ?
Are you planning to use standard SAP (ESS/MSS or others for example) ?
I'm not saying that WD4A is "better" than WD4J.
There's no such thing.
Each option has its pros and cons.
You also can't tell that WD4J is more secure or scalable than WD4A. Or the opposite.
And, believe me, WD4J is still going strong with a lot of customers.
But things are changing, and for me WD4A would make more sense if you want to be aligned with SAP.
Now and in the future.

Web Dynpro JAVA VS. Web Dynpro ABAP

Hi,
I'm interested in advantages and disadvantages of WD JAVA & WD ABAP. Could anybody give me some "detailed" information about it?
We need any information you can give us.
regards,
Sharam

Hi,
Web Dynpro for ABAP:
Web Dynpro for ABAP or 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).
The use of declarative and graphical tools significantly reduces the implementation effort
1) Web Dynpro supports a structured design process
2) Strict separation between layout and business data
3) Reuse and better maintainability by using components
4) Automatic operation of the Web Dynpro application using the keyboard
5) User interface accessibility is supported
6) Full integration in the reliable ABAP development environment
for more see:
http://help.sap.com/saphelp_nw2004s/helpdata/en/77/3545415ea6f523e10000000a155106/frameset.htm
Web Dynpro for Java:
Web Dynpro is a client-independent programming model of the SAP NetWeaver technology platform for developing user interfaces for professional business applications. It is based on the model view controller paradim which ensures that the business logic is separated from the presentation logic. This architecture is visible in the Web Dynpro perspective of the SAP NetWeaver Developer Studio (NWDS).
Web Dynpro helps you with the development of Web applications by:
1) Ensuring platform-independence with the meta model approach
2) Minimizing the implementation effort through declarative programming
3) Supporting a structured design process by applying the model view controller paradigm
4) Providing reuse and better maintainability by using components
5) Providing graphical support with tools in the Web Dynpro perspective
6) Providing the SAP NetWeaver Java Development Infrastructure (NWDI) which supports team work with different services such as source code versioning and the Central Build Service.
for more see:
http://help.sap.com/saphelp_nw2004s/helpdata/en/15/0d4f21c17c8044af4868130e9fea07/content.htm
The concept of Web Dynpro ABAP is identical with Web Dynpro Java and offers more or less the same functions
hope it helps

Web Dynpro Java timesheet to Web Dynpro ABAP timesheet what changes needs to be done from EP side

Hi All,
We are moving Web Dynpro Java timesheet to Web Dynpro ABAP timesheet.
what changes needs to be done from EP side?
I have made Web Dynpro ABAP iView calling Web Dynpro ABAP timesheet and linked it with page.
But It is showing an error 'Web Dynpro Application CATDATARECORD does not exist'.
Please suggest what other changes needs to be done.

Hi Anurag,
I have added new Web Dynpro ABAP iView to the same page in which Web Dynpro JAVA iview was added and made ABAP iview visible.
And this page is already assigned to role.
How should I link this ABAP iview so that it get replace by the Web Dynpro JAVA iview.
And the application name (CATDATARECORD) is correct and Web Dynpro JAVA is using the same application.
But now we want new time timesheet for that what changes needs to be done?
Please suggest.

Using Web Dynpro authentication for a Web Service call

Hi all,
I want to develop a Web Dynpro that calls a Web Service running on the same Web AS (7.0). The Web Dynpro will be integrated in a Portal. The web service that has to be called is automatically generated when we create a guided procedure :
http://help.sap.com/saphelp_nw2004s/helpdata/en/44/44c59fd7c72e84e10000000a155369/frameset.htm
In my Web Dynpro, I imported the WSDL of this WS and created a model.
The first time I tried to call the WS in my Web Dynpro I got an authentication error :
Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (401) Unauthorized. The requested URL was:"http://<myHostName>:50100/GPRuntimeFacadeWS/GPProcessExposing?style=document&pid=CA544E9B629A11DB91480017A48D672A&pver=0.5"
So I hard-coded an HTTP authentication :
 model._setUser("myWASuser");
 model._setPassword("myPassword");
And the Web Service call now works.
Now the next step is that the WS call is made by the user that runs the Web Dynpro. So I found this documentation :
http://help.sap.com/saphelp_nw04/helpdata/en/59/e8e95d1eba48dfa86ae91ad8816f5d/frameset.htm
It would resolve my authentication problem, AND the transport issue : at the moment the Web Service URL is stored in the Logical Port of the WD model, and at transport time, a rebuild of the WD project will be needed.
So I applied what is said in the doc : from the point of view of the Web Service consumer, I just had to add :
 model._setHTTPDestinationName("STARTGP");
(where STARTGP is the name of the destination I created in the Visual Administrator with a "Logon Ticket" authentication.)
before the execute(), and I removed my hardcoded authentication.
Unfortunately, nothing changes... I still get a 401 authentication error.
Does anyone have an idea about this ? Or maybe a workaround ?
Thanks in advance for any suggestion.
Regards,
Julien

Hello Julien,
I have a scenario similar to yours. A client webdynpro application accessing a EJB methods exposed as web service. Those EJB's methods calls R3 RFC's. The client requirements' was to allow SSO through all the layers (Webdynpro -> EJB WS -> RFC). The Webdynpro and EJB's are deployed on the same WAS.
Solution:
1 - Create a RFC Destination on Visual Administration provide the R3 connection parameters and set the Authentication for "Current User (Logon Ticket)". Save your Destination;
2 - In your EJB Project open your Web Service Configuration, on the Security page, set:
 Authentication Mechanism: HTTP Authentication
 Basic (username/password)
 Use SAP Logon Ticket
3 - In your EJB, implement the following code to create JCO Client for the RFC invocations:
Object obj = ctx.lookup(DestinationService.JNDI_KEY);
 DestinationService dstService = (DestinationService) obj;
 RFCDestination dst = (RFCDestination) dstService.getDestination("RFC", "<YOUR_RFC_DESTINATION_NAME>");
 Properties jcoProperties = dst.getJCoProperties();
 JCO.Client jcoClient = JCO.createClient(jcoProperties);
4 - In your EAR Project, open your "application-j2ee-engine.xml" and add the References:
 "tc/sec/destinations/service" as Service
 "tc/sec/destinations/interface" as Interface.
5 - Create your EAR File and Deploy;
6 - Check if the web service now requires Authentication: go to http://<host>:<port>/index.html and click on Web Services Navigator. Test your Web Service. Your Web Service should requiere you to log in before execute the test;
7 - Go back to your Visual Administrator and create a HTTP Destination. Provide your WS URL (should be something like "http://<host>:<port>/<WS_NAME>/Config1?style=document"). Choose Authentication: Logon Ticket. Save your Destination;
8 - Go to your webdynpro project, import your WS Model. (If you have already created it, you have to delete it and import it again, refer to this blog on how to reimport WS Models: /people/bertram.ganz/blog/2005/10/10/how-to-reimport-web-service-models-in-web-dynpro-for-java How To Reimport Web Service Models in Web Dynpro for Java );
9 - Open your model's Logical Ports node, go to the Security tab, and choose "Use SAP Logon Ticket";
10 - In your webdynpro code, before you call the ws invocation (should be something like that: <YOUR_NODE_DEFINITION>.modelObject().execute();), include the following line:
<YOUR_NODE_DEFINITION>.modelObject()._setHTTPDestinationName("<YOUR_HTTP_DESTINATION_NAME>");
11 - Save All Metadata and deploy your Webdynpro App. Test your results.
I hope it helps you, as the documentation on how to implement this scenario is scattered through the SDN and all the SAP help portal.
Best regards,
Paulo.

Calling a Web Dynpro application from a web application

Hi everyone, I've got a problem I hope someone can help me resolve.
What I wanna do is to show a login form, which is part of a J2EE web application (contained in a SAP Web AS), an after the user submits the required information, I have to redirect the user to a Web Dynpro application, which is contained in the same Web AS, but I have to redirect this user using single sign on.
I'm not sure about what I have to do, I'm new in these technologies, I think I need to use UMFactory, but I have made some investigation and I'm not so sure about what I have to do yet, can anyone give me a hand with this?

Hi Joel,

Exchanging data between a Web Dynpro application and SAP Web Shop

I'll try to keep this as clear as possible:
1) We have the SAP Internet Sales system running, which has a series of Business Object classes and corresponding Backend Layer objects that can return data from several sources.
2) We are able to create our own Backend Layer objects that would return data from a component called IPC, which is a Java component.
3) I would like a Web Dynpro application to retrieve data from this backend layer object, but I am not experienced enough with Java to know if what I want to do is possible. I don't think that I can use JCo, because I am trying to get a Java component (class?) in Web Dynpro to access a Java class remotely.
4) I think I am asking is this: is there a way for a Java to Java connection to be created, much like Web Dynpro can use JCo to connect Java to ABAP systems?
If this is a glaringly obvious question to Java programmers, my apologies!
- Tony.

Somebody on another forum recommended using RMI. Which would be the better option in terms of ease of implementation?

Web Dynpro application calling external web server using HTTPS giving error

Hello,
I don't know whether this is the right question in this forum but my ABAP web-dynpro applicaiton is expected to call another HTTP application on external web server through HTTPS. Presently it is calling through plain HTTP but we want to have HTTPS.
Here are the steps that we followed based on the link from help.sap.com
1] Received the certificate files from external web server
2] Created SSL Anonymous client
3] Imported the certificate files under this client and added into the certificate list
4] Re-started ICM
5] Created RFC Destination of type HTTP to connect to external server with SSL option and basic authentication. This RFC destination was working under plain HTTP.
When tried with Test connection it gave error "ICM_HTTP_CONNECTION_FAILED".
Any idea what might be missing. Thanks in advance.

Converting Web Dynpro project into a Web Dynpro DC

Hi
I have a Web Dynpro project created.
Now I want to convert it into a Web Dynpro DC (Development Component).
Could anyone tell me if there is a standard procedure to do this?
Right now, I am following the below procedure:
Copy all the folders under root folder->src-> packages of Web Dynpro project into root folder->src-> packages of Web Dynpro DC.
Rebuild the DC.
But in this procedure I am getting errors (in view code) as the required interfaces (example, IPrivate<<component-name>>.java) are not getting generated when I re-build the DC.
Could anyone help me with this issue?

Hi Aditya,
I have used two way for this and both worked fine for me.
1. While creating DC project at the end there eill be a check box, which when you tick will show your local dynpro project and you can then import that.
2. Create DC project after that copy the component of your local dynpro project and paste it on the option where you can create the component of DC project.
After pasting click next - next so that everything remain in sync.
After that check if you have any compilation error, check them if they are because of some jar files.. you have to add the library files by using the option -> DC Metadata ->DC Definition ->Used DC.
If you got no compliation error, then just rename the component ( again click next) and then deploy.
otherwise you may get deployment error.
Hope this helps,
Thanks,
Namrta

GP + Web Dynpro (Interface o Application)+ Web Services

Hi,
I have a scenario, in which I require to create a web dynpro, which will be utilized in a Callable Object, inside GP. This web dynpro will be like a form, which will be fed from 2 sources.
An external Web Service, that brings information from a website, spefically from a catalog.
Information filled by the user, in the fields of the form.
In short, the form is composed of information supplied by a Web Service and information completed by the user.
I would like to know if is possible to create a web dynpro, in NWDP, in order to be included in a Callable Object, inside a Worklfow in GP.
Regards.

Hi David,
yes, it is possible, you can create the callable object for the webdynpro and you put it into GP work flow..

Moving from Web Dynpro Java timesheet to Web Dynpro ABAP timesheet

Hi
We are in the process of moving from Web Dynpro Java ESS timesheet to Web Dynpro ABAP ESS timesheet. When using Web Dynpro Java ESS timesheet it is possible to enter time using a daily or weekly view.
When using the Web Dynpro version and ensuring the period type is set to weekly view for the data entry profile it is only possible to enter time on the weekly view, the tab for the daily view is no longer available.
Still using the Web Dynpro version and changing the period type to daily view I can enter time using the daily view and the weekly tab also becomes available, but the weekly tab is read only.
Do you know if it is possible to make daily and weekly timesheet entry for one data entry profile.
Thanks
Mark

Yes you can have only one view ie weekly or daily as per your CATS profile in CAC1.
but of course you can select multiple profiles
Configuration
The application configuration HRESS_AC_CATS_1 is provided by default and allows you to provide default values for the application parameters. It also allows you to specify the layout and appearance of the application.
The following application parameters are provided:
HIDE_CLOCK_TIMES_IN_WEEKLY
Hides the clock times in the weekly view.
MULTIPLE_PROFILE
Enables the selection of multiple data entry profiles from the dropdown list

Web dynpro abap cannot display web page

Hello
when running Test in se80 on my web dynpro application the browser says it cannot display the web page.
1. the url of the wd application is http://<hostname>.domain.ext:8000/sap/bc/webdynpro/sap/<component name>
2. rz10 says that profile NSP_DVEBMGS00_<hostname> has icm/host_name_full = <hostname>.domain.ext
3. rz11 says that icm/host_name_full = <hostname>.domain.ext
4. smicm says that icm/host_name_full = <hostname>.domain.ext
5. in etc/hosts on vista 32bit version 6002 I have put:
127.0.0.1 localhost
127.0.0.1 <hostname>.domain.ext
10.10.0.10 <hostname>.domain.ext
<empty line>
I also have
SAPGLOBALHOST <hostname>
rdisp/mshost <hostname>
and no values at all for
SAPLOCALHOST
SAPLOCALHOSTFULL
in the profiles.
The following works:
http://localhost:50013/sapmc/sapmc.html?SID=NSP&NR=00&HOST=<hostname>.
Can anyone help me? I read that many of you have solved this but, you see, I do not understand what you have done.

Setting icm/host_name_full to <hostname>.domain.ext in rz10 in profile NSP_DVEBMGS00_<hostname> means:
1) I can no longer see my web dynpro view layout in se80 - instead of the view layout I get a browser screen that says the page cannot be displayed;
2) I get the same browser screen saying the page cannot be displayed when running the wd application test.
If I remove that parameter in rz10 then:
3) I can see and work with my view layouts in se80;
4) I get a 500 rabax state error when I do the wd application test;
5) I can do a successful wd application test by changing the url manually in the browser from <hostname>:8000 to localhost:8000 ... as in
