Looking for a beginner guide - Adaptive RFC call BAPI in Web Dynpro Java

Hi,
im new in SAP Developeing. I developed some basic web Dynpro applications (after some tutorials) and they are all working.
Now i want to build an Web Dynpro application with an adaptive RFC Model.
I already imported the adaptive RFC Modell with a function Model (BAPI Z_...) from the R3 System successfully.
But if i deploy the application i will get following error:
com.sap.tc.webdynpro.services.exceptions.TypeNotFoundException: type extern:mypackages.com.types.BapiModel:mypackages.com.types.Zmbs_Bapi_Dispo_Orderdata could not be loaded: com.sap.dictionary.runtime.DdException: TypeBroker failed to access SLD: Error while obtaining JCO connection.

........Looks like a have a Problem with JCO.
Is there a good guide, which explains the Basic steps in developeing Web dynpro applications and BAPI ?!

thank you guys for all the answers.I have to read all the documentations.
to my szenario:
I installed on my notebook the Trial Versions of:
SAP NetWeaver Application Server 7.00/Java AS 7.00
SAP NetWeaver Developer Studio Version: 7.0.14
All my basic Web Dynpro Applications in Java are running (even with Adobe Interactive Forms) on the local NetWeaver Trail- Web AS Trail perfectly.
Now i want to connect per RFC to another SAPERP Server, which is in the intranet.
I did the whole RFC tutorial with the flights -
http://help.sap.com/saphelp_nw04/helpdata/en/c3/76b45d9688e04abe1a1070410ddc1e/content.htm (also with the JCO codeing etc)
so my web dynpro application should work.
I think I have to configure - like ramesh said something on the NetWeaver Trail.
So what do i need and configure excactly on my Netweaver Trial to work with RFC - to call the BAPIS in the other System?
- SLD ? JCO ?
If i over Web Dynpro - Content Administrator - >
it says "Connection to System Landscape Directory (SLD) could not be opended successfully." and all the buttons
create Jco destinations etc. are greyed out.
I didn´t configured the SLD and JCO in the Netweaver yet.

Starting Web Dynpro - absolute beginner question

Hello Web Dynpro gurus,
i have couple of completed & working customer ABAP programs (with their own selection screen logic and their own Z transactons)...
I should make those programs work in Web Dypro (to enable Portal usage of programs)...
I have some ABAP experince, but not OO, and I haven't worked with Web Dynpro component yet...
What would be the best approach in starting to learn Web Dynpro, links are wellcome?
Is there a way of integrating existing ABAP program in a Web Dynpro?
Or do I have to start developing separate Web Dynpro program anew, from scratch?
I ask this because these programs have complex selecton screen logic (implemented in 'AT SELECTION-SCREEN OUTPUT') that i'd like to keep in Web Dynpro program as well...
Thank you for your replies...
Kind regards,
Tom

How can I set the data binding between Web Dynpro & Database table

Dear friend,
I am a beginner of Web Dynpro. I want to develop my simple project like these:
1. Create my own database table via Dictionary Project such as TAB_USER and have 3 fields: USER_ID, USER_NAME, USER_POSITION and I have already deployed & archived it.
2. Create my own Web Dynpro Project, and create the input fields as User ID, User name, User position and icon 'Save' on the selection screen and I have deployed it already.
For the process, I want to input data at the screen and save the data in the table, please give me the guide line like these:
1. How can I set the data binding between Web Dynpro and Database table ?
2. Are there any nescessary steps that I will concern for this case?
Sorry if my question is simple, I had try to find solution myself, but it not found
Thanks in advances,
SeMs

Hi,
You can write your own connection class for establishing the connection with DB.
Ex:
public class ConnectionClass {
static Connection con = null;
public static Connection getConnection() {
try{
Context ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("jdbc/TSPAGE");
con = ds.getConnection();
return con;
}catch(Exception e){
return null;
You can place the above class file in src folder and you can use this class in webdynpro.
You can have another UserInfo class for reading and writing the data into the DB .

ABAP Objects and Web Dynpro

Hello everyone,
I would like to know if it is possible to have instances of a class as a part of a controller context. You know, like if you added a service call to a BAPI or a function group, but with method calls to an object instead.
I have a feeling, that it is uncommon to bring Web Dynpro and the object orientation of ABAP Objects together.
For example, i don't want the event handling code of my controllers to call function groups, which in turn make calls to my object oriented model. Is there a way to skip that nasty imperative step?
Sorry for asking questions which may sound vague or naive, I'm kind of a beginner regarding Web Dynpro and ABAP.
cheers,
Jens Barthel

There's no need at all to have function modules in the way.
You can have either controller attributes or context attributes defined as object references, and then call methods from those objects instead...
In both cases, you just have to use TYPE REF TO instead of TYPE when defining the attributes.
Furthermore, if you have a central class through which you interact with your OO model, you can define it as Assistance class and then you'll have an instance automatically in all the controllers...the drawback / advantage is that you do not control its instantiation which is done by the framework.
Regards

Web Dynpro Layout cannot be displayed

Hi Guys,
I am a beginner using Web Dynpro technic and I would like to know if there is a configuration need to be made to Internet Explorer or in SE80 to display the layout correctly?
For example, I created a text element in a view and in the Layout Tab the Web Browser always tells me that "This program cannot display the webpage"
Is there a special parameter to set up to enable Internet Explorer to display the Web Dynpro Layout? I cannot really find documentation on the subject actually.
Thank you in advance for your answers.
Sylvain

I post this every once in a while, but everyone should be aware that having to make an entry in your hosts file is NOT normal. I know a lot of people post that as solution, but if you are having to make an entry in hosts file to resolve the URL of your ABAP AS then something is wrong with your network configuration. Your basis administrators should work with your network administrators to get a proper DNS entry setup for your ABAP system. Surely you don't expect that all end users accessing you WDA applications will have manual entries in their hosts file.

Real time scenarios where Web Dynpro is used

Hi Experts,
I am a beginner with Web Dynpro (ABAP ), i have developed a couple of simple web dynpros for practice purpose. I would like to know the below things to get a better idea on the technology
1. Can anyone who have worked on Web Dynpro share the real time applications which you worked on.(I am not expecting any technical details, i want to understand the scenarios in real world where this technology is used).
2. If some one can link web dynpro's with CRM/SRM that would help me more.(Once again i need the business scenario)
Thanks in advance.
regard's
Sudheer V

Hi Sharath,
Thanks for your response, it was really a useful link. But once again they all talk about technical details but what i was looking for was business scenarios where web dynpro can be used effectively.
When i was searching for this i found one such scenario where web dynpro gets the quotation details from the CRM system and creates a sales order with reference to the quotation in the SAP R/3.
I was actually looking for scenarios like the above with some technical details for implementing the same.
Please let me know if you know scenarios something like the above one.Thanks.

Re: Web Dynpro ABAP Theme Editing

Dear Programmers,
I'm a beginner with WebDynpro for ABAP ,too.
and my question is:
Is it posible to edit the color and design from UI-Elements like buttons, fields and tables
to make it conform to an internel styleguide?
Best regards,
Henrik.

First of all, please do not ask new questions in an existing forum thread. I have forked your question into its own thread.
Web Dynpro ABAP automatically inherits the theme of the NetWeaver Portal.
http://help.sap.com/saphelp_nw70/helpdata/EN/42/cbf9fabaa86babe10000000a1553f6/frameset.htm
Therefore when you customize the theme of the portal, you are also adjusting the Web Dynpro ABAP theme.
Here is the help link for working with the Portal Theme:

ABAP Web Dynpro CSS Stylesheets

Hallo,
I have a question concerning "ABAP Web Dynpro". My current task is to implement an application for our company intranet. This application must have the look an feel (corporate design) of the company I'm working for. How can I manage this by using ABAP Web Dynpros?
Where can the Stylesheets be found and how can I change them in order to fit our corporate design.
While answering please consider that I am a raw beginner concerning ABAP Web Dynpros.
Thank you in advance.
Kerstin Röck

You need to Change the Themes , For that you need ThemeEditor. You can download that from SDN. First install that and then Download the theme from Mime repository. and then Create a Theme Editor project (It is basically NWDS which consists of ThemEditior plug in).
Here you can change the CSS properties and then Go back and create a New theme under the Respective mime Repository.
Search in SDN also you get lot of articles and Forum questions.

SPRO vs. Web DynPro vs. PCD

Hi guys,
Coming from a beginner's point of view, when I want to configure and customize ESS, I'm trying to understand
1. When to use SPRO or Web DynPro or PCD .
2. Under what circumstances should I use SPRO over Web DynPro,
3. What functionalities does SPRO has over Web DynPro

Hi There !
Use SPRO
to add, remove Services for the ESS.
to Change the Description of Texts Displayed.
to Have different Images Displayed.
to add Quick Links.
Use WebDynpro
to Change the Positions of Fields on ESS Screen.
to add Custom Logic to Applications.
use PCD
to Change the ESS Menu Structure
to Organise the Menu as per your needs.
to Create different Roles
Cheers !

JSPDynpage Vs Web Dynpro Java

Hi Experts,
1)I want to know the differences between JSPDynpage and Web Dynpro Java.
2)Why JSPDynpage has become obsolete and Web Dynpro has taken over.
3) Is there anything that we can do in JSPDynpage and cant do in Web Dynpro ?
Comments are really appreciated.
Thanks,
Kumar.

Hi again. That's hard to say, because it really depends. We know that SAP will be pushing Web Dynpro, all new development will be done with Web Dynpro, most business packages that were developed in JSPDynPage have been rewritten using Web Dynpro. So, in SAP's eye, web dynpro may have "replaced" JSPDynPage. JSPDynPage is still widely used because companies may not want to spend the time to re-write in WebDYnpro. At my company, I've written 6-8 JSPDYnPage applications for our Portal, I have since re-written only 2 in WebDynpro, but the others can rewritten easily, but I haven't had the time. My goal is to get rid of JSPDynPage completely from our portal applications and go with Web Dynpro.
I think it would be very good for a beginner to learn JSPDynPage first. This will give him a chance to know a little about what is going on underneath. Since you have to code every part of the application, you learn things that you wouldn't using a tool like WebDynpro. After getting the hang of JSPDynPAge, then learn WebDynpro, you will quickly appreciated the value of Web Dynpro after doing JSPDynPAge.
Visual Composer is designed for the "Business Analyst" type developer, this is why there is no code writing with VC. It does allow for rapid development of "Simple" applications, but if there are some complex things in your application, VC will not cut it, Web Dynpro would be the next choice. So no, VC will not replace WD.

Rich Heilman
