Environment needed for developing, deploying the ABAP Web Dynpro

Hi all,
We have the following ECC environmnet in our office.
ERP 2005, RELEASE 6.0
KERNEL 7
COMPONENT ECC 6.0 NON -UNICODE SYSTEM
BASIS & ABAP SP 14
We also dont have Enterprise Portal and no PI or XI. can we develop ABAP Web Dynpro without EP?
I want to develop Web Dynpro's using ABAP. Can i do it? Do we need to install any thing else? any plug in..or do we need to upgrade our service pack?
We are on service pack 14 and on ABAP Stack.
Some one kindly help..this might be a simple question for many people...but i am really in need of information and could not get proper idea after reading the SDN and help.com
if some one has a link .that explains the environmnet that i should have for Web dynpro ABAP..please help.
Regards,
Jessica Sam

Thomas,
Thanks a lot for your patience. Few more minutes of your valuable time..need help.
So i can conclude that with my environmet and ABAP statck ..i can develop Web dynpro ABAP and BSP but not Adobe Forms.
We have BI system in our office which runs on Java Stack and our ECC system is only on ABAP stack.
But we were using ABAP Web services to build interfaces b/w SAP and .Net applications and hence we wanted to use SOAMANAGER,
But SOAMANAGER runs on Java Stack and we dont have Java stack on ECC but have on BI.
So what we did was..did some BASIS settings in BI and ECC systems and finally able to use SOAMANAGER of BI system to manage , create and deploy web services from our ECC system whihc is on ABAP Stack.
Similarly can I also use the Java Stack in our BI system and do some settings at ECC end such that I can buid the interactive forms in ECC and use the Java Stack of BI system.
Kindly please help..i am not getting answers to such questions in help.sap.com...may be people like you who are well experience will only able to guide me better.
Kind regards,
Jessica Sam

Creating 'Z' views for Standard ABAP Web dynpro Application

Hi Experts,
I am totaly new to ABAP web dynpro objects.
In our project there were some client requirements which required us to change the properties of the Views related to the Webdynpro. The Client now has said that he needs to apply some enhancement pathces on his system. Due to this, the changes made to the Views i.e all the changes done in standard code are lost.
The client now wants a long term solution where all the changes need to be done in 'Z' implimentataion so that changes are not lost every time the pathces are applied.
Is it possible to create an entire new 'Z' Views for the standard Webdynpro instead of standrad ones?
If Yes how does one link them to the Webdynpro application ?

Hi
Have a look at following article about enhancing webdynpro applications.

Requirements for the development of ABAP web services...

Recently at TechEd in Vienna I saw a demo of the development of an ABAP service. It all looked fairly easy, so when I came back I decided to try it out for myself. However, this mission seems to be compromised by the development environment not playing along. I've tried to encapsulate a small RFC function module inside af service on an IDES ECC 6.0 system and that went fairly well until I wanted to test the service.
At some point it is understood that one should setup a reference to a J2EE system in the WSADMIN transaction and that caused me some troubles as it looks like the IDES system that I tried it on doesn't have a java stack. How could I check whether that is true? I then tried to test the service directly under maintain service within WSADMIN and it sends me a popup screen and asks me to logon. After logging on the browser claims an internal error has happened.
What do I do now? Where do I start to check if everything is setup the way it should be? Is there a note or a how to guide somewhere?
Best regards,
Anders

Hello,
For creating and hosting ABAP web Services, you do not need JAVA stack. However, for testing Web Services using Web Service Navigator (from SOAMANAGER), you need J2EE stack.
If you are invoking Web Service from SOAPUI, .NET or some other third party tool, you need to create End Point for the service using SOAMANAGER and provide the Porttype WSDL to the third party system.

Hi,
this was actually some services which needed to be started through SICF. Once I have started the service sap/bc/public ETC.. and the web dynpro started working. Most of the SAP delivered demo apps are working
However for some ABAP web dynpro ( for some application XRPM ) I get some peculiar error. Please see below and if you could think of anything out of these.
I have already checked and found the both HTTP and SMTP services are working fine.
The following error text was processed in the system PXA : Syntax error in program /1BCWDY/56ZRPAZLU25M8S1BKV2T==CP .
The error occurred on the application server fmsap994_PXA_00 and in the work process 0 .

"Add To Browser Favorites" for ABAP Web Dynpro

Hi All,
In the Portal Environment, the end user has an option to "Add To Browser Favorites". This will trigger the "Add a Favorite" window in the Internet Explorer and the user can save the favorite as needed. Do we have a similar cabapility in ABAP Web Dynpro if the Web Dynpro is not delivered through an SAP Portal?
Thanks in advance for your help.

No. There is no similiar option in the Web Dynpro framework, nor can you access JavaScript in order to interact with the web browser and supply this feature. Browser Favorites can be maintained by the NetWeaver Portal Framework or in the NetWeaver Business Client by the surrounding frame. In the case of the NWBC, it isn't actually browser favorites but a separate set of favorites merged with Easy Access Menu favorites.

Want to handle event for component defined inside skin for host component

Hi,
Following is how my skinned button looks -
As can be seen, there is a checkbox - which is a part part button skin.
When mouse is over chckbox area and does clicked, I wanted to capture that event for checkbox as target. Objective is to mark checkbox as checked or unchecked when clicked on. I don't want checkbox to change its state when mouse is clicked over other area in button.
Don't know whether it is possible or not. If yes, what is the best way to do it.
Thanks in advance,

Hello!
I face the same problem with Failed to create delegate for component:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to create delegate for component

Caused by: java.lang.reflect.InvocationTargetException
Caused by: java.lang.NoClassDefFoundError: com.sap.tc.webdynpro.model.webservice.gci.WSTypedModelClass
I think this started after upgrading from 7.01 SP3 to SP5, but I'm not sure.
What was it that solved your issue?
*I found the error. My ProjectProperties.wdProperties did not contain the references it needed.*

How to view lifecycle for component usage

Greetings-
I have declared use of one component to another in the diagram view. I initially set the lifecycle to "CreateOnDemand" using the "New Component Usage" wizard but now I'd like to change this to "Manual". However, I don't see the lifecycle when I view the properties of the referenced Component in the diagram view. How do I find/change this?

Hi,
In WebDynproExplorer expand the "UsedComponents" node under your component .
Double click on the usedComponent and you can change the lifecycle property.

Use of multiple Applications for single webdynpro component in ABAP WEB DYNPRO

I am working on a object which have multiple webdynpro applications for single webdynnpro component.How to assign a different functionality to each application bcoz when we right click on webdynnpro component and select create webdynpro applications ,it just creates a application how so we assign diff functionality to each of them .Also in the parameter tab of the webdynpro applications ,there is a diff config id mentioned for each application.what is its relavance

Hi Sam,
Different functionalities for a single webdynpro component can be achieved by many ways. Among them is the use of multiple applications. Say for example if you want different views/windows to be displayed at the start up, you can achieve it by specifying at the default window, for each every webdynpro application.
And if you want control the fields, say for example you want to display input fields as editable for one application and read only for other application, you can achieve it through application parameters. Based on parameters, in HANDLEDEFAULT method of window controller , you can specify the type of behaviour , whether it has to editable or not based on parameters and same can be used at context binding of UI properties.
Application configuration can be used for personalization.Web Dynpro ABAP Application Configuration. This tutorial would help you understanding the concept much better. There can be multiple application configurations for a single application.

CAF DB Update for CAF Entity Service from Web Dynpro

Hi all,
I have created an entity service in CAF called Contacts which contains the following attributes.
phoneNo
cellNo
emailID.
Another entity service called "Person" is created. This contains the following attributes.
personId
personName
personAddr
contactsRef. (Cardinality -> 0..n , Relational Type -> Composition)
That means Contacts entity service is used within Person entity service. Now it is working fine within CAF service browser. Now the Web Dynpro DC of CAF application is used within another custom Web Dynpro DC project. I want to store data from Web Dynpro.
Within the context of component controller of Web Dynpro the structure is like
APerson
     |_ personId
     |_ personName
     |_ personAddr
     |_ contactsRef
                |_ phoneNo (Under contactsRef)
                |_ cellNo (Under contactsRef)
                |_ emailID (Under contactsRef)
So I have written the following code within web dynpro custom method.
APerson person = PersonServiceProxy.create();
java.util.List ls = new ArrayList();
for(int i=0; i<4;i++)
AContacts contact = ContactsServiceProxy.create();
contact.setCellNo("9092130156");
contact.setEmailID("[email protected]");
contact.setPhoneNo("432258");
contact.getAspect().sendChanges();
ls.add(contact);
person.setRelatedModelObjects("contactsRef",ls);
person.setPersonID("9999");
person.setPersonName("xyz");
person.setPersonAddr("ABC, KOL");
wdContext.nodeAPerson().bind(person);
person.getAspect().sendChanges();
CAFServiceFactory.getServiceFacade(idendityDefinition.class);
After saving the data from Web Dynpro I am trying to test it from CAF service browser. But I am getting only the parent row. I mean only the value of personId, personName and personAddr fields which I have stored from Web Dynpro. But no value is coming within the table for Contacts entity service for composition relation.
Could anybody help me how can I solve my problem?
Thanks & Regards
Chandan

Hi Chandan,
Can you do person.getRelatedModelObjects() and get the contact object, to check whether it is null, also check in the CAF DB whether the data you entered is present.
I am not sure the code is actually adding the contact model object to person.
Go thru this SDN Blog on usage of the CMI API's, there is a link for CMI documentation in it which might help you get the right code for adding the contact object.

Couldn't complete tutorial 'Integrating EJB 3.0 into Web Dynpro ...'

Hi All,
I am trying to complete the Integrating EJB 3.0 into Web Dynpro Using the EJB Model Importer tutorial that goes with SAP NetWeaver Composition Environment 7.1 SP3 Developer Studio.
Does anyone ever completed this tutorial because I have problems completing it. The result is very important for me because I need to use this technology for my essay.
In this tutorial you create a button that calls the method StudsBean.getStudent(String). In this method the object student is created and it will be returned. In several labels the information of the returned student should be displayed. But that doesnt happen, when I push the button no error occurs but the labels are still empty. When I try to debug the Enterprise Bean and Web Dynpro application I see that the method StudsBean.getStudent(String) is called and the propertys are set and the student object is returned, but still it isnt displayed.
After discussing this with a colleague I tried to search for a solution on the SDN and of course Google. First I thought I would be a bug but I only found 2 people with the same problem. I found it remarkable because its one of the key subjects of Java EE 5 and its a tutorial displayed in the welcome page of the Developer Studio.
So do you people think its a bug in WebDynpro? Because I am sure that I followed all the steps mentioned (a colleague checked it even).
Regards,
Sander

Hi Sander,
I guess, it's not a bug in Web Dynpro, maybe it's a bug in the tutorial
I tried something similar, but not following the tutorial and it works. I wasn't able to call the model from the view controller and I guess that's the problem. Take the code from the init-method of the view controller and put it to the component controller's init -method and the code inside the onActionGetStudent and put it into a method you create in the component controller, too. From onActionGetStudent just call this method in the component controller with some code like this:
wdThis.wdGet<your component controller's name>.<your method's name>;
Hope this helps
Kind regards

Specifying different initial views for different users in ALV web dynpro

Hi Friends,
I need to have 2 different initial view for my web dynpro application eg: View1 and View2. There will 2 group of users using the respective Views. However the first group should not be able to see other view(View2) and vice versa.
Please tell me whether it is possible and if yes then how to do it.
Regards,
Saud

Hi,
the ALV component has a public attribute - R_COMPONENT which is of type ref to IF_SALV_WD_COMPONENT_TABLE
you can call GET_PERSONALISATION on this reference to return a reference to the interface IF_SALV_WD_COMP_TABLE_PERS. This in turn has a method - SET_STANDARD_VIEW.
I think that this should allow you to set which ever view you want.
Hope it helps,
Chris
