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 <b>one</b> 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>");

Hi Mahesh,
You need to setup a Single Sign On between SAP Portal and ECC system where yoy are doing the development.
Ask basis team to setup the single sign on and usually this is the job done by Basis teams. Refer the below link to get some idea on SSO setup:

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.

Calling a Web Dynpro Application from POWL feeder class

Hi,
I know this question is asked before but never answered, but I try again......
I have a own POWL feeder class where I defined a button in method IF_POWL_FEEDER~GET_ACTIONS.
I know that this action can be handled in method IF_POWL_FEEDER~HANDLE_ACTION.
When pressing the button I want do call another web dynpro application.
How can I do this? -> Any Example Coding?
Thank you and best regards, Edgar

Hi Vineet,
it works, thanks a lot!!!! Best Regards, Eddy
P.S.: Here is the coding for triggering the event and passing parameters for the selected POWL table line:
METHOD if_powl_feeder~handle_action.

IF i_actionid = 'EDIT'.
*   Important: this triggers the event
    e_portal_actions-fire_wdevent = abap_true.
*   Pass parameters to event
    ASSIGN c_result_tab TO <lt_fligts>.
    lt_flights = <lt_fligts>.
*   Determine the first selected row
    READ TABLE c_selected INTO ls_selected INDEX 1.
*   Read selected POWL data
    READ TABLE lt_flights INDEX ls_selected-TABIX INTO ls_flight.
    CHECK sy-subrc = 0.
*   Pass parameters

Examples of 'calling a web dynpro application with parameters'

Hi!!
I'm I have been watching manual 'Web dynpro for abap: advanced concepts' in the sections 'url parameters' and 'calling a web dynpro application with parameters'.
Is there some example where these terms are seen.
Thanks in advance.

Hi Ana,
a window inbound plug can have parameters.
These parameters are automatically fished out of the URL by the framework.
So your inbound plug handler method has easy access to the parameters.
URL
http://<host>:port/sap/bc/webdynpro/sap/<your application>?param1=xyz&param2=abc
The application is configured to call an inbound interface(window) and plug.
The plug can be declared with parameters.
Double click on window inbound plug and add your parameters.
The parameters are made available by framework if present in Launch URL.
You can also call an application that has parameters directly entered on the parameters tab.
ie Parameters can be part of the application launch.
regards
Phil

Not able to run web dynpro application from portal.

Hi portal experts,
I want to run my web dynpro application from portal.
So created a seperate iview and a role for the purpose.
Assigned the iview to the role and also mapped a abap user id to the new role created.
But when I click on 'preview' the iview , getting the following dump.
Error when processing your request
What has happened?
The URL http://mnghcmsap:8000/sap/bc/webdynpro/sap/zhr_cp_admin/ was not called due to an error.
Note
The following error text was processed in the system HRM : Die URL enthält keine vollständige Domainangabe (mnghcmsap statt mnghcmsap.<domain>.<ext>).
The error occurred on the application server mnghcmsap_HRM_00 and in the work process 0 .
The termination type was: RABAX_STATE
The ABAP call stack was:
Method: CHECK of program CX_FQDN=======================CP
Method: STARTUP_CHECKS of program CL_WDR_CLIENT_ABSTRACT_HTTP===CP
Method: HANDLE_REQUEST of program CL_WDR_CLIENT_ABSTRACT_HTTP===CP
Method: IF_HTTP_EXTENSION~HANDLE_REQUEST of program CL_WDR_MAIN_TASK==============CP
Method: EXECUTE_REQUEST of program CL_HTTP_SERVER================CP
Function: HTTP_DISPATCH_REQUEST of program SAPLHTTP_RUNTIME
Module: %_HTTP_START of program SAPMHTTP
What can I do?
If the termination type was RABAX_STATE, then you can find more information on the cause of the termination in the system HRM in transaction ST22.
If the termination type was ABORT_MESSAGE_STATE, then you can find more information on the cause of the termination on the application server mnghcmsap_HRM_00 in transaction SM21.
If the termination type was ERROR_MESSAGE_STATE, then you can search for more information in the trace file for the work process 0 in transaction ST11 on the application server mnghcmsap_HRM_00 . In some situations, you may also need to analyze the trace files of other work processes.
If you do not yet have a user ID, contact your system administrator.
Error code: ICF-IE-http -c: 200 -u: INF51515 -l: E -s: HRM -i: mnghcmsap_HRM_00 -w: 0 -d: 20110209 -t: 121224 -v: RABAX_STATE -e: UNCAUGHT_EXCEPTION
HTTP 500 - Internal Server Error

Please let me know if I am doing the process correctly and also let me know if I am missing somthing.
Thanks,
Aditya.

Are you able to run teh web dynpro application independtly i.e. without creatin an iview.
http://mnghcmsap:8000/sap/bc/webdynpro/sap/zhr_cp_admin/ by using this link.
or there also you are getting the error.
i guess there also you should be gettign the error.
this is some problem with the FQDN settings in the abap system.
in the host name of the web dynpro applciation server one .(dot) is must.
so you might have to change the host name to some thing like mnghcmsap. from mnghcmsap
thanks

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 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
Jan 8, 2008 2:14:12 PM /userOut/deploy (com.sap.ide.eclipse.sdm.threading.DeployThreadManager) [Thread[Deploy Thread,5,main]] ERROR:

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

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.

HTTP 500 internal server error while starting abap web dynpro application

Hi there,
i have some problems concerning my web dynpro abap configurations in the system. When i start an application the browser appears and displays the http 500 internal server error. The required icf nodes are activated, as far as i know. the following properties are set:
hostname: aet
port: 8000
The generated url for the web dynpro application looks as follows:
http://aet.ls3001:8000/sap/bc/webdynpro/sap/zwdr_test?sap-language=EN
Maybe anybody of you out there has an idea for that situation.
Thanks for your afford and kind regards,
Albert

Hi Ulli,
the error message says:
UNKNOWN HOST
Description: Unable to locate the server named "aet.ls3001" --- the server does not have a DNS entry. Perhaps there is a misspelling in the server name, or the server no longer exists. Double-check the name and try again.
So the problem is the hostname.
When i replace the hostname with the ip of the server, the following error occures:
COULD NOT CONNECT
Description: Could not connect to the server "10.18.187.9".
But with SAPLogon, its possible to connect on the server by filling in the ip adress.
Kind regards,
Albert

Calling a Web Dynpro application from a web application

Hi everyone, I've got a problem I hope someone can help me resolve.
What I wanna do is to show a login form, which is part of a J2EE web application (contained in a SAP Web AS), an after the user submits the required information, I have to redirect the user to a Web Dynpro application, which is contained in the same Web AS, but I have to redirect this user using single sign on.
I'm not sure about what I have to do, I'm new in these technologies, I think I need to use UMFactory, but I have made some investigation and I'm not so sure about what I have to do yet, can anyone give me a hand with this?

Accessing Web Dynpro application outside portal

Hello alles,
Our customer wants to display a Web Dynpro application result on a regular hmtl intranet page, i.e. without showing the portal.
We have tried with html frames, but end up with a flickering or empty screen. The problem occurs both with a quick link to the application within the portal, an SSO link, a link to the iView, a webdynpro/dispatcher address ...
It seems as if the problem occurs with all WD iViews, but not with e.g. a regular News iView.
Do you have any suggestion on how we could solve this? Reasons?
Thank you in advance!
Brgds,
Caroline

Storing user defaults of Web Dynpro application on portal

Hi folks,
I am trying to develop Web Dynpro application that runs in an iView on a portal. I would like to remember certain user defaults for this application (e.g., user default plant). User also has control over this value, so whenever they change it, the value should be update on a backend as well.
My first thought was to use PCD, but I am not sure how to do that - all the code examples for I found for PCD looked like they were created for portal application, not Web Dynpro ones.
Anybody here actually done anything similar?
Edited by: Alexei Isaev on Jan 29, 2008 8:20 PM

Hi Alexei,
If you need to store default values for a portal application, you may consider your development in Web Dynpro for ABAP. I have not come across application level personalisation yet in Web Dynpro for Java, unless someone else can throw some light here.
