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,

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 .

How to get the ep user information data in the web dynpro?

Hi all
I want to create a web dynpro application on EP.I want to get the ep user information data in the web dynpro.How can I do?Thanks.

Lin,
Two steps to achieve this:-
Step 1: Add the following code in your view Controller:-
IWDClientUser user = WDClientUser.getCurrentUser();
IUser objUser = user.getSAPUser();
wdContext.currentContextElement().setXXXX(objUser.getUniqueName());
wdContext.currentContextElement().setYYYY(objUser.getFirstName());
wdContext.currentContextElement().setZZZZ(objUser.getLastName());
where XXXX, YYYY , ZZZZ are the context names.
getUniqueName : Gives Login id of Portal user.
getFirstName : Gives First Name of the Portal user.
getLastname : Gives Last Name of the Portal user.
Step 2 : Use "Organize imports" and make sure that you have the following two libraries added in the build path of your project. You can do these by right clicking on your project name ==> Properties ==> Java Build Path ==> Libraries ==> Add External jars.
The external jars are :
com.sap.security.api.jar
com.sap.security.api.perm.jar
Finally rebuild your project and deploy.

What kind of data types in Web Dynpro can be bound to Interactive Form?

Hello
Apparently it is not possible to bind a Web Dynpro Context variable of type boolean to a checkbox in an interactive form. We get the PDF Document Render Exception until the data type is changed to string, then the generation seems to work. Does anyone know what data types in Web Dynpro other than String can be bound to an Interactive Form Document? Is there any information about this in help.sap.com/adobeforums.com/elsewhere? I have researched a bit, but couldn't get a general statement on this topic.
Thank you for your help!
Kind regards
Bettina Hepp

Hi,
You can Bind the Boolean type of webdynpro to the CheckBox in Adobe Interactive Form.
Just define the value Attribute in the Context of type Boolean and bind the Checkbox in Aif with this attribute.
Sample Code:
if (wdContext.currentContextelement.reason == true)
ur validations.....

Context from Web-Dynpro-Component-Interface & Customer Extention Fields

Hello all,
A main component uses a Web-Dynpro-Component-Interface and defines an external maping to it. Web-Dynpro-Component-Interface has a context and a window. At runtime implementaion of Web-Dynpro-Component-Interface is provided.
All works fine, but how can i create an implementation with view which contains customer extention fields? Unfortunately only fields from context of Web-Dynpro-Component-Interface are visible. I can not even extend the context of Web-Dynpro-Component-Interface via enchancement framework.
I assume, it is possible with dynamic programming, but why is it not possible in declarative way?
thanks
regards
Paul

Hello,
I found this documentation:
Implementation of Interfaces for Customer Developments
Using interfaces in a Web Dynpro component benefits customers by giving them a clean basis for their own further developments. When creating a local development, you can implement a used interface in a separate component and add your own aspects to an application delivered by SAP.
http://help.sap.com/saphelp_nw70/helpdata/en/a9/19eebc1e2943dbb2d443095d017ae9/content.htm.
I think it must be a correct way to extend SAP programms with customer fields. Please reply, issue is very important.

Data storage in web dynpro

Hey people!
Im pretty new in web dynpro, and i want to store the data i input in the inputfields somewhere.. either in a database (oracle) or xml file.. someone got any tips? and if i choose to go for oracle, do i have to create an EJB as well? or could i just write the connections and queries in the views?

I think that suggested way is to use SQLJ in a EJB and then use that EJB in your web dynpro project.
Check out this thread.

Calling session bean's business method through web dynpro component

Hi All,
Can anybody tell me how to call a session bean's methods through a web dynpro WITHOUT java-model or web service model ??
I have following scenario:-
1. Stateless Session bean having two business methods
2. Web Dynpro component
3.Now i want to call business methods without using any model. I have got following piece of code but I dont know how to go about it.
4.Where do i have to set JNDI name for session bean? which interface will be looked for?
5. Do I have to declare public part for EJB DC? If yes, how?
//This is inside web dynpro component
InitialContext context = new InitialContext();
o = context.lookup(JNDIName);
TestSessionbeanHome homeRef = (TestSessionbeanHome) PortableRemoteObject.narrow( o,
TestSessionbeanHome.class);
TestSessionbean beanRef = homeRef.create();
<returnValue> = beanRef.<ejb method name>
Please help to get a step-by-step approach to this case.
Thanks and regards,
Amey Mogare

Hi,
If I comment out the part that is using session bean's business method, DC is building fine.
And if I uncomment, then compiler is unabl eto resolve business method(s).
And i would like to mention that my EJB + J2EE App DC is building properly, but it havent yet deployed properly as I am waiting for data-source-alias name prefix to be configured by ERP team. So will this be a reason why Web Dynpro DC is not able to resolve business methods ??
Because Web Dynpro DC is able to resolved all interfaces of Session bean and entity bean. But when it comes to business method, its not able to resolve.
Any more ideas why it is not happening?
Pls help.
Now i went through some forum posts regarding this and found that we also need to add EJB DC to Java Build Path for WebDynproDC>Properties>Java Build Path.
I did this and now it is able to resolve business methods and DTOs as well. So to summarize I did following:-
1. Added EJB DC (complete DC) as a Used DC to Web Dynpro DC with Buid-n-Deploy-n-Run time dependency
2. Added Sharing reference of J2EE application DC to Web Dynpro DC -->Properties
This reference I constructed as follows:-
<vendorname>/<name of j2ee application as appearing under display name tag in application.xml (replacing '/' with '~')>
So my Sharing Reference becomes:- <vendorname>/reqpstapscreqpstapja_reqid
3. Added EJB DC to Java Build Path in Web Dynpro DC's properties
4. Then I added following piece of code to get object of SessionBean class
InitialContext context = new InitialContext();
Object o = context.lookup("java:comp/env/ejb/SessionRequestIDBean");
SessionRequestIDHome homeRef = (SessionRequestIDHome) PortableRemoteObject.narrow(o, SessionRequestIDHome.class);
SessionRequestID beanRef = homeRef.create();
beanRef.<business method>
But After doing this I am facing another problem :-
The build fails saying it is not able find the package for DTOs. But when I see the Component Controller's code it is not showing any red or yellow marks.
Can anybody pls help me out here?
Thanks and regards,

SRM 7.0 find transparent table name from Web dynpro Component

Hi ,
I am trying to find the transparent table name from Web dynpro component dictionary structure. I am working in SRM 7.0. Please let me know how to find the transpartent table for a field.
Thanks,
Monica

hi,
your question is very unclear and does not relate to performance.
SRM uses webdynpro ABAP so the recommendation will not help.
Do you need a technical UI element?
Or the application table where the business data of an UI is stored???
If it is the later, then you can use the SQL trace, change to element you are interested in, and trace it. The table should appear in the trace in connection which an UPDATE command. Still a bit cimbersome.

No component usage created in enhanced web dynpro component

Hi experts,
I am facing the following problem:
I'd like to enhance a web dynpro component in order to add a popup window. The popup is triggered by the process_event method. So far everything works just fine.
But the popup needs to know some context attributes from the main component, and I cannot create a component usage in order to set the context mapping.
Does anybody know how to solve this issue?
Thanks and regards
Jan Phillip Höft

Hi!
Thanks for your answers first of all.
I need the popup to be a stand alone web dynpro component, so I guess the assistant class doesn't do the trick because I can not access it in the popup component.
The popup is called when the business object is saved. So that the user is asked to notify other users that the document has changed. In this popup the user should fill in the message and click a button to send it and close the popup.
So I tried the OBN approach as well but with two problems :
1. I cannot close the popup component by coding (button click) because it has no direct parent component
2. The save event is not run through properly so the document stays locked by the user. But I didn't look into this yet.
So it would be perfect to have an embedded popup component which is based on a stand alone web dynpro application so it can be closed properly but it need at least access to the guid of the main component.
Anybody got an idea for this?
Thanks and regards

Is it possible to serialize a web dynpro component controller?

Hi,
Is it possible to serialize a web dynpro component controller and deserialize it for use?
I have one web dynpro application WDA1 for web dynpro component WDC1. And another web dynpro application WDA2 for WDC2 will be opened in a new window triggered by a button action in WDC1.
Iu2019d like to pass the object reference of WDC1 component controller to WDC2.
I first tried to use a static member of a class object but found out that even the static member is initialized and set in WDC1, itu2019s still initial when I access it in WDC2.
Then I searched the forum and found one article Passing Object ref to Webdynpro Application while calling from BSP screen .
The recommended way is to serialize the object reference and store in a DB table, later on read it out and deserialize it for use.
I tried serialization using the following code, but when itu2019s deserialized, the result is initial.
Can anyone share some ideas on this?
Serialize
data: ostream type string,
           xslt_err type ref to cx_xslt_exception.
***** serialize model class
try.
      call transformation id
      source model = wd_comp_controller
      result xml ostream.
    catch cx_xslt_exception into xslt_err.
endtry.
Deserialize
    data: istream type string,
          xslt_err type ref to cx_xslt_exception.
    istream = ls_db_sel-obj.
    data lr_wdc type REF TO ZIWCI_BY_WDC_SERIALIZE.
    try.
        call transformation id
        source xml istream
        result model = lr_wdc.
      catch cx_xslt_exception into xslt_err.
    endtry.

When you say new window, I assume you mean new browser window. This is a separate user session then. This is why the singleton pattern doesn't work. Have you considered using a new dialog window instead of a new browser window. It will be modal, but will share the same user session as the parent window.
>Why do you choose this approach over cross-component usage ? component usage is the way webdynpro components are >to be reused.
>You can also consider using Singleton OO pattern class to share data between these two components.
Neither of these approaches will work if you are using separate browser windows. Such an approach results in two separate user sessions (perhaps even running on different application servers depending upon how you have load balancing setup) and therefore can't share data using either of these approaches.
In general the idea of serialization and then writing the string ito a server cookie or other database table is sound. I don't think you should try and serialize the component controller, however. Serialization only saves and restores public attributes - not protected or private ones. So in general a class has to be designed for serialization. The component controller is much too complex and wasn't designed for such an operation.
I would suggest instead extracting the data you want to share out of component controller or context and serializing it into a custom class and passing that to the other component.

Transport issue when copying a web dynpro component

Hello All.
I have a web dynpro component lets say ZTest and now I want to copy this, I gave the new one a different name i.e. ZFINAL, now when I copied, it asked me for the trasnport and when I asked to create a new transport I got this message "Class ZIWCI_ZFINAL does not exist" and then I clicked the green arrow again and it created a transport for me. After this process I activated my web dynpro component successfully, my web dynpro component has 3 views and 3 windows. When I looked at my new transport (for ZFinal), I only saw three tasks attached to teh transport i.e. 1. Interface 2. Info Object from the MIME Repository and 3. Web Dynpro Component but I didn't see Controller (Web Dynpro), Definition (Web Dynpro) and View (Web Dynpro) attached to my transport. Now I wonder when I release my transport to Q I may have issues.
Note: My old trasnport (which has Ztest)has all the missing objects: (Web Dynpro), Definition (Web Dynpro) and View (Web Dynpro)

I resolved it myself.. I had to write the transport entry manually for the views and windows and even the component controller definition.

The Web Dynpro component cannot be generated due to serious (syntax) errors

Hi everybody,
While I was developing a web dynpro application, I had an error but I couldn't understand this error. Before I took this error message, only I changed bound one context node to another context node in a RadioButtonGroupByKey.Therefore, when I pushed activate button, I took an error message.This error message said "The Web Dynpro component cannot be generated due to serious (syntax) errors". What does it mean ? How can I find out where is the error in the application. Also, I think the reason of this error message is about a BC problem. I am waiting for your comment urgently.

Hi ,
Just delete the context (by using the context binding) and bind the field with the correct node and try to activate .
One more suggestion is that after deleting the binding and before binding to other node check it that whether that binding was properly deleted or not.Some times its not deleting the binding.
Hopely my suggestion may work.

Dynamic insertion of MIME object into a web dynpro component

Hi,
I want to dynamically insert a MIME object of type JPEG or type GIF into my web dynpro component at runtime.
I was unable to find the database table which contains the list of MIME objects for a particular web dynpro component.
Can you please help me out with this?
Thanks in advance,
Adithya
Moderator message: wrong forum, please have a look in the "Web Dynpro ABAP" forum.
Edited by: Thomas Zloch on May 23, 2011 9:55 AM

Hi Muzammil Bichoo ,
when you copy the wda component, it will be copied and will be in active state, once all the components are activated means, windows, views, everything will be available.
now create application for your component, if you have more than one window(interface view) select the one which you need for the application.

Web Dynpro component - Flat file upload

Hi,
We have a requirement to upload a flat file to Planning cube (real time cube) through Web Dynpro component.
Web Dynpro component which we have developed is able to read the records from the flat file.
Now, the issue is u201CHow can we save the records read from the flat file to planning cubeu201D?
If anyone has worked on the similar requirement, pls reply. Thanks in advance.
Note : We have a planning sequence which will be executed on the click of UPLOAD button.
This planning sequence has a filter on Infoprovider (cube which we are using for planning) and a planning function of type u201CFile uploadu201D in which we have defined the flat file format.
Aggregation level is made on Multiprovider which has 2 underlying cubes (One is realtime and other one is standard).
Is there any function module in which we can pass the name of the flat file so that it will be uploaded in planing cube?
Regards,
Ankur
