Web Dynpro DC witch references a simple Java DC - NoClassDefFoundError

I need use the logic in a simple Java Project or a Standalone Proxy Project (weg.net/test/dc2) by a Java WebDynpro (weg.net/test/dc1), but when the DC 1 call the DC 2 this show a runtime error of class notfound java.lang.NoClassDefFoundError: net/weg/test/Test ).
The DC 2 is a Simple JAR, that is not possible deploy directly and it should be deployed with the Web Dynpro (DC 1). In other words, I believe the jar of DC2 should be inside the DC 1 (web dynpro).
The public part is declared perfectly. I have tried all combination of configuration of used DCs (DC 1 has the option build time, run time and strong at moment). In properties u201Clibrary referencesu201D I added u201Cweg.net/test/dc2u201D.
Thanks,
Cleiton Garcia.

Hi,
Did you create the public part of type SDA (Can be packaged into other public parts).
If you are testing in local server:
Dont deploy using "DeployNewArchieve and Run".
Deploy using "RightClick>DevelopmentComponent>Build && RightClick>DevelopmentComponent>Deploy"
See this blog
/people/bala.krishnan2/blog/2006/09/25/bid-adieu-to-bots--using-captchas
And this is another way:

Web Dynpro Application For developing a simple calculator

Dear Experts,
I am trying to develop a simple calculator application in abap web dynpro .
but i am not able to enable the buttons (1 to 9) . that is what i want is like how it happens in a normal calculator if we press 1 , then in the screen, 1 comes and if 11 then twice we press 1. Like wise i want if the button 1 is enabled then in the input field it should take 1 and if 11 then it should take 11. Kindly give some suggestions to develop this application.

Web dynpro rfc model reference

Is there a way to change the jCOclient reference
of rfc model after creating the model for example from WD_RFC_MODELDATA_DEST to WD_R3_RFC_MODELDATA_DEST

Yes Natti.
You can change the reference to the model by changing the Application /Message server settings of the
MODELDATADEST and METADATADEST.
Open the cotent administrator and click the "edit" button of the destination that you want to change. Then change the Application / Message server setting from the client1 (current client) to say client 2 (the required client).
Please reward appropriate points.

Can Web Dynpro for ABAP supports Mobile devices as like web dynpro for java

HI,
Experts,
Web dynpro for abap application supports mobile devices as like web dynpro java application supports the mobile devices.

Hi Shabeer,
if you are looking for Mobile Web Dynpro, this is only supported with Java: [Mobile Web Dynpro |http://help.sap.com/saphelp_nw04/helpdata/en/7d/28fa3e7cb1d861e10000000a114084/frameset.htm]

Web Dynpro and Oracle

Greetings to all!
We had been two weeks trying to develop a simple application with Web Dynpro that brings data from an Oracle database. We have defined a table in the Java Dictionary with such fields and names that in the data base. We have created a project J2EE with a EJB Entity with properties and methods for the fields of the table. For the tableView model in Web Dynpro we had to use a Java conventional Bean since it did not accept the EJB import directly. Also we have defined a system with the connection properties, user, password... of the Database. Everything seems to work fine, but sometimes we obtain the java.lang.NoClassDefFoundError exception: com/sap/tc/webdynpro/progmodel/gci/IGCIComponentDelegate and the others just an empty tableView. Can somebody help us? It would be to us of much utility a simple project of this kind with all the properties, detailed references...
Thank you very in advance.

Hi Srikant,
I have worked on similar stuff, but the scenario was a little different. I worked on creating Web Services using EJBs, but the basic part was that, the web service was supposed to interact with the SQL Server database. So maybe I can help you...
First thing which is needed is that you have created the JDBC Connector in your Visual Administrator correctly. If you wish to cross check, you can see my answer in the following thread:
JDBC error
In this thread itself I have given the code which is the solution to your problem (this is what i believe). I am pasting the code again:
<b>InitialContext initialContext = new InitialContext();
DataSource dataSource = (DataSource)initialContext.lookup("jdbc/MyAlias");
java.sql.Connection connection = dataSource.getConnection();</b>
You can use this code in the method of your EJB, and then you can easily use this connection object to access your database tables using SQL queries.
And if by any chance you are looking for a step wise procedure for creating a web service from an EJB, then give me your email address, i will send you the doc.
Bye

2) Within any Web Dynpro controller, three shortcut variables are always present, whose values are all derived from the member variable wdThis.wdThis is the Web Dynpro specific self reference and should be used in preference to the standard Java self reference of this.
3) The member variable wdThis is populated from a parameter of the same name, passed in by the Web Dynpro framework when the controller is instantiated.

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?

ABAP Web Dynpro - OfficeControl - Word Integration

Hi,
i have a problem concerning the office control of the abap web dynpro.
I have a textedit box on the view of a web dynpro. Now i want to transfer the data from the textedit box to the word document. I used the "IOS_TEST_WORDPROCESSING" as an example.
Everything works fine, if there is only one line of text in the textedit box. If i put for example three lines in it, word opens and now i have the choice for a data seperator.
The word document contains only one field as a "MergeField" like the field of the word document used in the "IOS_TEST_WORDPROCESSING".
Could anyone give me a hint how to solve the problem.
With best regards
Markus

I have the same problem. I want to integrate an ABAP Web Dynpro in GP, but there is no way to implement an Interface from GP like it is in JAVA. That means you cannot maintain input , output parameters and give a status back to GP. Seems that in ABAP the WD is not integrated in GP.
I went to the relevant developement departement an they gave me the following answer.
In GP you can maintain input parameters for a ABAP Web Dynpro Application manually which will be displayed in the apllication UI URL . Then you need a function module to map the input parameters inside the url to the ABAP Web Dynpro context. Output parameters are not possible in GP with ABAP Web Dynpro. It is also not possible to give back the processing state to GP from your ABAP web Dynpro Application like it is in JAVA. Only the GP framework provides a button to complete this Step manually by the user.

Print Functionality for Web Dynpro ABAP Application

Hi All,
I am using the standard print button provided by FPM in my application.
The application has a date navigator control as well as a dynamic ALV with fixed and on fixed columns.
I would like to know if the application has to do any implementation to provide print functionality. If yes, how do we do it?
Will it consider all the ALV columns as the ALV could have horizontal scroll bar.
How do we test it?
Defining output device in our user as LOCL is enough to test it? Are there any limitations?
Findings until now:
I just happened to see that gc_event_print FPM event is raised and the application uses interactive PDF form to implement printing.
I am not sure if this satisfies my requirement.
Could you help me in providing more information regarding this? You could also provide me some web dynpro examples for reference.
Regards,
Rekha

>I just happened to see that gc_event_print FPM event is raised and the application uses interactive PDF form to implement printing.
I am not sure if this satisfies my requirement.
As you are already suspecting, the FPM doesn't provide the print functionality itself. It only raises the event and the specific application is then responsible for how it wants to produce the output. Therefore it is your job to design the output (generally using PDF forum).

Creating Client-side Image Map in Web Dynpro

Hi,
How can I create a client-side Image Map in Web Dynpro application?
My application consists of a screen-size image in which several areas will have to link to URLs and actions. I have browsed through the "Web Dynpro UI Element Reference Guide," but could not find anything appropriate.
Can someone give me an advice? Thanks.
Teecheu

It doesn't, there is no corresponding UI control for this.
There is only onAction event on BusinessGraphics (have not working with them since SP5, eventing did not work at that time) and onObjectAction in GeoMap (never see it in action, probably an option for you if your map is geographic map
