Initialization of A Web Dynpro Application.

Hello All,
I am a novice to the wonderful world of Web Dynpro for Java.
I am trying to build an application which will run in the portal.
The user intetrface will have a drop down box and some web control and a button. I want to poulate the drop down boxes with some values from calling RFC.
My questions would be
1> in the wdDoInit() method can I make call to the RFC?
2> If we can make a call is the way it is meant to be or is there any other way.
I will be executing a RFC once the form is sumitted any ways..
Any inputs for helping me out will be greatly appreciated and of course re-warded well..
Thanks and Regards
Manoj Kumar.

Hi Manoj,
If you are new to Web Dynpro you should check the Web Dynpro Sample Applications and Tutorials:
https://www.sdn.sap.com/irj/sdn/developerareas/webdynpro?rid=/library/uuid/49f2ea90-0201-0010-ce8e-de18b94aee2d
Here is a direct URL to a tutorial on how to access a RFC from web dynpro:
https://www.sdn.sap.com/irj/sdn/downloaditem?rid=/library/uuid/f0b0e990-0201-0010-cc96-d7ecd2e51715
For your question if to execute the RFC from the wdDoInit or once the form is submitted: of course both are possible, it depends of the application logic: When do you want it to run? in the init stage or the submit stage.
Hope it helps, Adi

Error while running web dynpro application

Hi Experts,
I have a web dynpro application that is consuming web services from PI 7.1
I have deployed the application on PI 7.1 server and created web service destination also.
I have tested the web services and they are working fine.
I am geting the following error when i am running the code,
The initial exception that caused the request to fail, was:
com.sap.engine.lib.xml.util.NestedException: Illegal conversion

HI GLM,
If i comment the code in component controller i get the screen, but when i initialize the model and parameters in doInit() method i get error. I am using 5 web service and getting same error for all, so i have commneted rest and currently dealing with one.Below is the code,
 EventDetails model = new EventDetails();

Short dump when trying to open FPM for Web Dynpro Application

Hi,
I am receiving a short dump while trying to open a Web Dynpro Application in FPM. I go to SE80 and open the Web Dynpro component 'FPM_OIF_COMPONENT'. I then choose the application '/sapsrm/wda_l_fpm_oif'. I then click Web Dynpro Application -> Test -> Execute in Administration Mode. A new IE browser is opened and I then receive a short dump. The name of the short dump runtime error is 'OBJECTS_OBJREF_NOT_ASSIGNED_NO' and the exception is 'CX_SY_REF_IS_INITIAL'.
I have not used FPM before. I would like to use it to remove the 'Close' button from this application. Do I need to initialize FPM before using it?
Please help.
Thanks,
Jeff

Hi Chinnu,
Your understanding is not correct, he is trying to execute the application /sapsrm/wda_l_fpm_oif'.
Hallo Jeff,
everyone have suggested lots of possibilities. Nothing works for you. I would suggest the following.
Go and execute any other FPM application which uses FPM_OIF_COMPONENT,does it work ?
If it works then you can narrow down that /sapsrm/wda_l_fpm_oif is not working and you can raise a OSS ticket.
If it is not working then you have to see if you have right BASIS versions to use FPM.

Hi Siva,
to my understanding - your problem has nothing to do with J2EE server configuration - your application is already deployed on the server and running (brings error though):
at com.sap.examples.welcome.wdp.InternalStartView.<init>(InternalStartView.java:43)
so your class is already called.
DC = Development Component, but if you created a "simple" WebDynpro project - you should read the hint as "are you sure your project is properly deployed?"
I got similar messages (see your quota about NoSuchMethodException - I'm not really sure I was getting NSME, but definitely "Failed to create delegate for view") in case a Java-type context attribute was not initialized (e.g. you create context attribute of type java.util.Properties, do not put any object there, and request the attribute value). Check if you properly initialize context attributes.
Another thing - I presume you're running DevStudio of the same version as your server. DevStudios of different versions generates different sources - there could be problems in run-time when out of synchronization.
Best regards,
Nick

Error - Creating a Web Dynpro Application Accessing ABAP Functions

Dear All,
we are trying to implement a web dynpro application with accessing ABAP functions.
Previous tasks:
- insert the ABAP system into the SLD from the NWDI System (Transaction RZ70; the ABAP system is correctly insert into the SLD => technical systems)
- equipped the JCO connections with the web dynpro content manager (ping and test = OK)
Its the standard tutorial out of the SDN called Creating a Web Dynpro Application Accessing ABAP Functions.
Some hints:
- There are no errors after the implementation and the rebuild of the project in the NWDS
- The auto deployment works fine to the development runtime system. The application is shown in the Web Dynpro content manager

- Im able to start the application out of the Web Dynpro content manager with run => only the user interface is displayed without any functionality
- The normal start over the NWDS fails => error text
com.sap.tc.webdynpro.services.sal.core.DispatcherException: The requested deployable object 'local/J08_Flugdat_Daventdcflight~xxx.com' and application 'FlightListApp' are not deployed on the server. Please check the used URL for typos.
There two different URLs in use.
Start via NWDS:
http://frasapp562:50000/webdynpro/dispatcher/J08_Flugdat_Daventdcflight~xxx.com/FlightListApp
Start via web dynpro content manager:
http://frasapp562:50000/webdynpro/dispatcher/xxx.com/aventdc~flight/FlightListApp
For test purposes, we started the BAPI (BAPI_Flight_Getlist) on the ABAP system directly. It works.
Any ideas about the system behaviours (different URLs and missing functionality)?
Thanks a lot in advanced!
Best regards
Christoph

The Error has been solved The implementation of a method was missing....

Passing a parameter while calling a web dynpro application on portal

hi
I am having a web dynpro application which retrieves data from R/3 system via RFC using Jco destinations define in the Portal.
Now we have different kinds of portals running on the same WAS, now I want the application to run which access data from different R/3 systems thru different JCo destinations.
I need to create a logic such that mu application runs fine on any portal with any Jco destination.
Is there any provision to achieve this.
kindly let me know about this.
Thanks and regards
kris

Gopi,
there's an parameter called "sap-wd-arfc-useSys" you can pass to the application, to change the used JCo-Connection (read more at http://help.sap.com/saphelp_erp2005/helpdata/en/f4/651741f163f023e10000000a155106/frameset.htm)
so, if you're running the WD-aaplication on one WAS and call it from different portals, you have to create three (or six with the META-connections) JCo-Connection on your WD-WAS.
In a WD-application you can access URL-Parameters with:
WDWebContextAdapter.getWebContextAdapter().getRequestParameter("<your URL Parameter-Name>");

Amr Azim,
You must have logged in thru a dedicated connection to any server through say VPN before deploying.This way the sdm uses the same login as that of already establised connection.
So 'sign of' all connections to any servers before deploying and redeploy your application.Here you will be prompted to supply the sdm password and deployment shall proceed.

I am getting a error while executing the Web Dynpro Application Page.

Hi All,
I am getting a Error while executing a web dynpro application :::
: Navigation in Phase WDDOMODIFYVIEW Cannot Be Triggered. Component: Z_WEP_PERSONAL_DATA, View: OVERVIEW, Window: Z_XXP_PERSONAL_DATA
I have checked this error description in ST22 :
What happened?
    The exception 'CX_WDR_RT_EXCEPTION' was raised, but it was not caught anywhere
     along
    the call hierarchy.
    Since exceptions represent error situations and this error was not
    adequately responded to, the running ABAP program
     'CL_WDR_CLIENT_APPLICATION=====CP' has to be
    terminated.
Error analysis
    An exception occurred which is explained in detail below.
    The exception, which is assigned to class 'CX_WDR_RT_EXCEPTION', was not caught
     and
    therefore caused a runtime error.
    The reason for the exception is:
    Navigation in Phase WDDOMODIFYVIEW Cannot Be Triggered. Component:
    Z_XXP_PERSONAL_DATA, View: OVERVIEW, Window: Z_XXP_PERSONAL_DATA
Can u plz help me regarding this error.
Thanks,
Deepika

>Navigation in Phase WDDOMODIFYVIEW Cannot Be Triggered
Looks to me like you are trying to fire a navigation plug within WDDOMODIFYVIEW. According to the rules of the WD Phase Model this is not allowed.

Error while accesing ABAP web dynpro application

Hi Experts,
We are getting warning symbol on web page status bar, when we are accessing the ABAP web dynpro application
only first page of application is getting loaded and when we click on page it is showing error on status bar and we can perform any thing.
once we double click on warning icon,
below details are coming:
Line: 1491
Char: 3
Error: Object Expected
Code: 0
URL: url of the ABAP web dynpro application
This scenario is occuring for many ABAP WD application for a client.
Please guide how to solve this issue?
Thanks!
Piyush

Hi
First try a very simple application with nothing in it just one text saying Hello World
Run it and see what happens.
Also check if your url uses FQDN name. something like https:
company.name.co:50000\.......
If you do not use the FQDN it will always show a script error on the bottom and some functions will not work e.g
dropdowns.

Yuval.

Error while implementing a web service in web dynpro application

HI All,
I am trying to use a webservice in a web dynpro application.
Web service description:- This is a very simple application which takes two String inputs and when submitted displays the string in the concatenated form.
Web dynpro:- I used this web service in the web dynpro as an adaptive web service model.
The Layout design consists of two input fields which are mapped to the request fields
ex : - Request_Add.Add.S1 and Request_Add.Add.S2
A text area to display the response:- Request_Add.Response.AddResponse.Response
And a button which invokes the execute method
public void onActionWebserviceCall(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
 //@@begin onActionWebserviceCall(ServerEvent)
 wdThis.wdGetWebserviceCompController().executeRequest_Add();
 //@@end
When I am trying to run the application I am getting error:-
Exception on execution of web service with WSDL URL 'http://<Host>:<Port>/EjbWebservice/Config1?wsdl' with operation 'add' in interface 'EjbWebserviceVi_Document'
Kindly reply.
Thanks
Neha

Hi,
Yes I have tested the web service in Navigator . The WSDL is also properly generated.
I have not publish the web service in UDDI but as per my understanding this is not necessary. please correct me if I am wrong.
Thanks

Error while deploying the Web Dynpro application

HI All,
I have developed a Web dynpro application. Now when I am deploying the application I am getting an error.
Description

Deployment exception : Cannot determine sdm host (is empty). Please configure your engine/sdm correctly !
Can any one please help me regarding this.
Regards

Hi Neha,
It seems that there is problem with your SDM server. It seems that during J2EE engine configuration SDM server is not configured. Actually this configuration is done by Basis Team.
By the way try out your Server setting:
Go To:: Windows -> Preferences -> SAP J2EE Engine
[Mention the required details over there]
And Check whether you are getting Active SDM Server under J2EE Engine.

I would be appreciate if anybody could help me with this issue.
Regards,
Leandro Fonseca

At the same time if more users are deploying then you may such 'deployment aborted' errors check if there are more child instances for the J2EE engine.If not ask your basis administrator to create more child nodes to balance the load on the server instance.Also You can find out the server details at
"http:
<hostname:portnum>\index.html"select system configuration-you can get the details of the SDM and the j2ee engine from there.You need to have proper credentials to get the information from the above url.
Provide those details in the NWDS.

Application specific theme in CE7.1 web dynpro application

Hi,
where can I find documentation about setting up application specific themes for Java Web Dynpro applications running in Composition Environment 7.1? I've found documents that refer to the Visual Administrator but since it doesn't exist anymore in CE7.1 there must be a different way.
Regards,

Hi Kevin,
Yes, charts are going to be supported in WD html in next versions of VC( Q3 2008).

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?
