Model class deleting in Web Dynpro

Hi ,
I want to delete few model classes which I imported from RFC which are redundant. Is there any way I can delete these classes.
From the ABAP end also few RFCs have been deleted and now I am getting error at the Web Dynpro end.
Your reply greatly appreciated.
Regards,
Rakesh

Hi,
Delete the model node from the custom controller which is bound to the RFC node during the mapping. and also delete the methods created in custom controller to call the execution of RFC. then remove the model from the used models area. Reimport the model and do the mapping steps.

Consuming web service with with a custom class parameter in web dynpro

Hi,
I have developed a web service. It is tested an it runs fine. The webservice is retrieving and returning Data Transfer Objects (POJOS). I have made the model-context binding, then the view controller - component controller binding with the input parameters for one method of the web service.
In an input field I have set the value to a attribute of the DTO. (This appears: Request_CreateProductGroup.CreateProductGroup.ProductGroupDTO.CompText)
When I run the Application I get following error:
com.sap.tc.webdynpro.model.webservice.base.exception.BaseModelRuntimeException: No object for mandatory target role 'ProductGroupDTO' of model class 'CreateProductGroup' with cardinality '1' maintained

How to delete deployed Web Dynpro Content ?

Hello again,
simple question (i hope):
How can i delete a deployed Web Dynpro Application from my portal ?
Due to all these tests and trials there are a lot of useless WDApps in my portal.
Did not find anything in help.sap.com or in the portal.
Thank you !

Hi Andreas,
You can remove the deployed components through either SDM or through Visual administrator
1) In SDM, you will find a tab 'UnDeployment'. In this view, you will be able to see all the applications currently deployed. Select the applications that you want to undeploy and proceed to undeploy.
2) In Visual Administrator, under Server->Services->Deploy, you will find a radio button 'Application'. From here too you can select the required application and remove them.
Hope this helps,
Best Regards,
Nibu.

Differences between compiling a VC model with Flash or Web Dynpro

Hello forum,
Is there anyone capable of telling me what are the main differences between compiling a Visual Composer model with Flash compiler or Web Dynpro compiler.
I've noticed that some important features aren't available when I use the WD compiler, such as creating a popup directly from the output of a table and I can't install a scroll bar to navigate through the table records (it only allows me to place some navigation buttons in the bottom of the table, and this is not a very user-friendly solution).
If you were me, would you choose the Flash compiler?
By the way, do you know a way to increase the performance of a report created with VC? When I execute the iView on the Netweaver Portal, I see that a iview compiled with Webdynpro consumes less 15MB of memory when running the report than a similar iview compiled with Flash.
Thank you.

Ricardo Inácio

I found this old post while searching for something else. The main difference between Flash and Web Dynpro modes is that Flash works and Web Dynpro most emphatically does not. Some of the (many) disadvantages of Web Dynpro mode.
1. It will not let you design your own screens. The designer will let you resize and position your fields thus giving you the illusion of being in control, but at runtime it will resize your fields and position them where it thinks fit. This greatly increases development time since you can never be sure what any changes you make to your screen will look like until you run it.
2. You cannot include horizontally and vertically aligned fields in the same form; depending on the option you choose it will align them all vertically or horizontally. Which means that if you do need eg a horizonal row of pushbuttons at the top of your screen followed by a set of vertical fields, you have to use a separate form for each.
3. You cannot use the Editing mode = Read-only mode to make all the input fields in a form non-entereable. You can select it in the designer,but at runtime it doesn't take a blind bit of notice. The only way to make a field non-enterable is to check the Disabled box which turns it a very pale and almost invisible grey which looks awful.
4. You can't change the font or colour of texts.
5. Lots of the controls are not available eg the clock.
6. You cannot create toolbars on forms, or rather you can but at runtime it just ignores them.
7. Adding a hyperlink to a pushbutton does not do anything (this is my latest discovery).
All of the above work in Flash mode. We have to use Web Dynpro because we need the screens to work with screen readers for visually impaired viewers, but anyone who does not have this constraint should avoid using it like the plague.

Create utility class in Web Dynpro project

How do I create my own utility java class but keep it in the Web Dynpro project?
Do I have to create a separate java project and have the WebDynpro classes import it or can I keep it in the Web Dynrpo project?
I tried adding my own java class to the Web Dynpro project and when I did a rebuild all, the generator erased it.
Ideally, I would like to keep everything in the same project if possible as this utility class will only be used by the WebDynpro project.

Open Eclipse "Navigator" or "Package Explorer" view and put your class under folder src/packages.

Quick Question: ABAP web-dynpro model relies on JCO?

Hi gurus,
As mention in subject. Does ABAP web-dynpro model relies on JCO?
Did a quick search without solid answers...

JCO, is Java Connectors to connect SAP from Java world
You don't need any JCO when you are in the same ABAP Stack
There is no model Nodes/Attributes in Web Dynpro ABAP as in Java, because you are in the same ABAP Stack

WDVisibility type paramter in Java Bean(Web Dynpro DC in CE 7.1)

Hi All,
I need to set a WDVisibility type paramter in a java bean and i am able to do so.It imports com.sap.tc.webdynpro.progmodel.api.WDVisibility class .
The problem is when i am creating a Java Bean model it is not allowing me to select the Java bean class it gives an error message" Invalid Class : No class files found for JavaBean : com/sap/tc/webdynpro/progmodel/api/WDVisibility".
The java Bean class exists in Web Dynpro DC>src folder.
Any Pointers?
Regards
Avinash

Hi Ondrej ,
Refer the above links to convert the component of the first dc as a public part.
Then declare the methods which are written in the component controller of the first DC in the interface controller with the same signature.( When method is called automatically component controller method is called)
In second dc in component controller properties tab add the reference of the first dc.
Then access the method in second dc as
wdthis.wdget<UsedComponent name>Interface.methodname();
Thanks & Regards,

Using document attribute of caf in web dynpro

Hie Experts,
could somebody give me some information how to use the document attribute of caf in my web dynpro model?
I have created some application and entity services with simple attributes and document attributes.
I imported the model into the corresponding web dynpro project and I am using them with the generated proxy classes. It's working fine, but I don't know how to use the document attribute.
If I want to attach a document to an entity service, do I have to upload the file an fill the fields of document node or is there any operation in a proxy class where I can pass an InputStream and it is handled automatically?
Best regards
Manuel

Vitaliano,
You make a very good point. And it is probably the way that we will go. However, my task is to evaluate Web Dynpro and Visual Composer for our needs. Especially since the graphing capabilities in Web App Designer are limited for our needs. We will, at some point, have a need to combine warehoused information in BI with real-time data in R/3. I'm anticipating that this is where Web Dynpro will be useful for us. Therefore, my questions as stated regarding Web Dynpro. I just find it strange that none of the SAP documentation elaborates on the topics that I am concerned with, even though tantalizing capability summaries are dangled throughout.
Thank you.

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 ABAP in SAP E-Recruiting

Hi,
We just imported SP8 for our SAP E-Recruiting 6.0. SP8 offers Web Dynpro ABAP as candidate UI. One question we have is how WD pages incorporated for recruiters who still use BSP pages. For example, when a recruiter logs into E-Recruiting and finds a specific candidate, he/she can click on "Candidate Profile" to get to that candidate's pages. In BSP technology, recruiter actually uses exactly the same pages that candidate uses for Work Experience, Education, etc.. With candidate UI using WD technology, does recruiter use the same WD pages when displaying candidate profile information? I have been searching all the possible places, such as IMG, SICF, in order find a spot so that I can set the switch on, but so far unsuccessful.
Any help is greatly appreciated.
Li

Hi Li ,
At best of my understanding in WD ABAP , its possible to make one WebDynpro page serving same purpose ( showing profile deatils ) visible for manty( Candidate , as well as Recruiter ) ....
I would like to know what exactly you want from web Dynpro ..then I will be in better position to tell you.
FYI ...
1) Web Dynpro ABAP
As the name suggests Web Dynpro for ABAP uses exactly the same meta model as its cousin Web Dynpro for Java. A Web Dynpro component, a Web Dynpro view, a Web Dynpro model, a Web Dynpro controller have the same semantics both for ABAP and Java. The main difference is the designtime environment, the development infrastructure and the runtime environment.
The designtime environment is properly embedded in the ABAP Workbench where Web Dynpro artifacts are simply a new category like BSP applications or classical dynpro based applications before. Also no surprises regarding the development infrastructure. The correction and transport system keeps track on all changes that are done, versions them and helps to propagate the Web Dynpro application from development to production like you would do with ordinary BSP or dynpro-based applications.
Last not least the execution platform is the ABAP server that produces application content ready to be integrated in the NetWeaver Portal seamlessly. Features like portal eventing can be used between applications written in ABAP or applications developed with Java.

Web service in Web Dynpro development Component

Hi All,
I have created a web service in SAP GUI and I have saved the WSDL file on my local PC.
Now when I create a web service model in a simple web dynpro project it works perfectly.
But when I do the same in a web dynpro development component; as soon as the web service model instance is associated with the activity in the DTR my application get hanged. I have to quit my NWDS. When I reopen NWDS my application shows following errors:

Hi Sidharth,
Which version of NWDS you are using. I was facing the same problem with SP16 sometime back.
I did find a workaround to do that. See, whenever you will create the WS Model in Web Dynpro DC, it will ask you to add some file in DTR..right!!........ do one thing press "Cancel" or "No" there. Then studio will ask one more time to add the files, in different dialog box though. Add the files from the second dialog box rather than the first one.

Using PMD with Web Dynpro

Hello,
We've been trying to integrate PMD (http://pmd.sourceforge.net/) with NetWeaver Developer Studio, but all we've been able to accomplish is it checking our own java classes. PMD completely ignores java classes generated by Web Dynpro. Is there a way to make it see those classes as well?

The source of Web Dynpro generated files aren't *.java files, but *.wdcontroller files
I'm not familiar with PMD, but you might need to add the extra file extension
(Being it Java source encapsulated in XML, you may run into a plethora of other issues, but you could give it a try)

How MVC related to ABAP Web Dynpro?

Hi
I am a java guy....Can you please explain me how MVC related to ABAP Web Dynpro. In java we have views, controllers and model..but in web dynpro abap i didnt find any model and they are writting all the businness logic in view only. They are not using any component controller as well.
Can any one please explain me this...
Thanks & Regards
Ravi shankar B

Hi
Webdynpro is not a complete MVC pattern stuff , but it has also a controller and views.Views are to be completely out of the business logic but webdynpro allows us to put business logic inside the views.
Controller and Windows acts as the Controller in the MVC pattern
Thanks
