Re: Debugging Abap webdynpro appln
Re: Unable to Debug WD ABAP application
Dedug is not working in Production Server.
a) Check on number of R/3 sessions opened at a time.
b) Check that user ID configured in portal using System Mapping Under 'Delegate User Administration' is the same user for which you are setting external breakpoint in backend system.

Error while configuring Debugging for WebDynpro Application

Hi Experts,
I am trying to configure Portal server for debugging a WebDynpro application.
In NWDS , in Debug configuration
When i tried to add my Webdynpro Project and application under Debug tab , No problem.
But when i checked J2EE Engine tab : it showed the following error.
<b>[J2EE Engine]: the selected server node does not run in restricted load balancing mode, please configure it correctly so that the URL extention can be used</b>
And ignoring it when i started debugging the application , the URL was formed like this :
http://<host>:50000/@@@DEBUG@@@7672950/webdynpro/dispatcher
/local/WDtest/WDtest?SAPtestId=1
with the error : The requested resource does not exist.
Details: Go to main page of this application!
Can anybody help me to fix the configuration.
Regards,
Ashish Shah

Hi,
To configure to the debugging mode... follow the steps:
1. Select "SDM" from J2EE engine (To get this view navigate thru Window--> Show View --> J2EE Engine)
2. Make a right click on "SDM" and choose "Enabling Debugging of Process"
3. Now, Navigate to Run --> Debug --> Select your Project as "Webdynpro Application" and click "new" button
4. Now give some name and Click BROWSE to select ur project and then click APPLY and DEBUG
Or if u use 2004s, then u can do the settings in Portal itself...which gives u more clear information... follow the link

Runtime Error While executing the WebDynpro Application

I am getting the Runtime Error While executing the WebDynpro Application. The error message is "TSV_TNEW_OCCURS_NO_ROLL_MEMORY".
It says like "
Short text
    No roll storage space of length 9728 available for OCCURS area.
What happened?
    Each transaction requires some main memory space to process
    application data. If the operating system cannot provide any more
    space, the transaction is terminated.
But while executing some other Web Dynpro Applications, i am not facing this problem.

Generally this error is a result of an infinite loop on internal table or select endselect statement where by severs temporary memory gets full. With no memory to insert new records in temporary memory system generates the dump.
Check your application or ask basis consultant to look at the memory parameters in instance profile.

How to set the WebDynpro application title (IE windows title)?

Hello all,
I would like to set the WebDynpro application title according to the current transaction ID. This title is the IE windows title that is shown on the upper left-corner of the IE browser.
Rule: [Object Instance Information] u2013 [Application Title] u2013 [Browser Title]
For example: Trans. <No.> - <My App> - Windows Internet Explorer
I would like to set <No.> dynamically on run-time according to my current transaction number.
I have this piece of code that gets a reference to the application info:
data: lr_app_info TYPE REF TO if_wdr_rr_application.
lr_app_info ?= wdr_task=>application->application_info.
And there is lr_app_info->get_description() method to have the description of the application, but there is no set method.
The application description can be hardcoded in:
tx. SE80, opening the WebDynpro component, then accessing its WebDynpro application. In the properties tab, there is a description field. I need to append transaction ID to it.
Do you know any way to implement this? This issue is for WebDynpro ABAP.
Best regards and thanks in advance,
Fouad.

Hello Satra,
Thanks for your reply. I already had a look into that thread, but my question is not related to the windows title of the WebDynpro component.
My question is related to the title of the Internet Explorer that we all see on the top left-corner. For WebDynpro , this is the WebDynpro application title. How can we change it?
I hope my question is clear now, and I wish someone can help me soon.
With kind regards,
Fouad.

Passing value from Adobe Interactive form, to the Webdynpro Application

Hi,
I have followed all the tutorials on interactive forms in WD for Java, & am able to successfuly display my context data in an interactive form.
However, i need help with the following:
1. Online scenario:
User has filled details in an interactive form & clicks on the submit button.
The Data from the form is NOT getting passed back to the WebDynpro application.
2. Offline Scenario:
User has filledup a pdf file(form), & has uploaded the form to the webdynpro application, using the file-upload UI element.
How do i read the data that the user has entered in that pdf file?
Any help with regard to these two queries, will be appreciated.
Thanks,
Hanoz

1) Online Scenario
check if the context mapping between UI elements and Context is properly done
check if the cardinality of the Context is alright.
2) Offline Scenario
you will have two views.
one upload view
and one interactive form view
in the upload view use the File Upload UI element.
in the Interactive Form View.... use the same view which you used to create the offline form, thus the interactive form UI element will already know the structure of data and the context mapping in the pdf file when you upload it.
Add the following line of code to the
method wdDoInit.
wdContext.getNodeInfo().getAttribute
("pdfObject").getModifiableSimpleTyp
e();
Add the following line of code right
before
wdThis.wdFirePlugOutToDisplay()
in the method onActionShowForm().
wdThis.wdGetTravelRequestCompControl
ler().wdGetContext().currentContextE
lement().setPdfObject(wdContext.curr
entContextElement().getPdfObject());
in the interactive form view, change the property of the interactive form.... MODE to usePdf.

How to secure the Webdynpro Application name ?

Hi Experts,
I have a requirement to send the Webdynpro Application name to Outlook inbox where the users will logs into that application and they will see the view the data and clicks on some action(Approve or Reject).
Now the my client does not want send that actual Webdynpro URL to outlook mailbox as it is having some security issues(host and domain details). Instead of that, can we change the actual Application name to any custom name by changing the host , domain and etc, parameters ?
Thanks in Advance,

Hi,
If you want to hide the application path, goto SICF transaction and then create an External Alias for your WDA application path and then send the Alias path name.
Suppose, you have the WDA application url as
host:port/sap/bc/webdynpro/<APPLICATION_NAME> . Instead of this you can just show
host:port/sap/<Your Name> ( or any other) using Alias.

Kiran

Hi,
Please follow the below process for passing data between two webdynpro applications using portal eventing.
Step1:-
Webdynpro Application 1 (Iview1)
Create an input field bind a context variable and have a button and write the following code in the button onaction.
public void onActionOK(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
com.sap.tc.webdynpro.clientserver.event.api.WDPortalEventing.fire("urn:com.sap.tc.portaleventing.example","show",
                    wdContext.currentContextElement().getHi());
Here Hi-->is the context variable binded to the input field.
Step2:-
WDDOINIT write the following code:-
com.sap.tc.webdynpro.clientserver.event.api.WDPortalEventing.subscribe("urn:com.sap.tc.portaleventing.example","show",wdThis.wdGetRaiseFireAction());
While creating the action it should have the following 3 parameters.
1.dataObject-->Type String
2.namespace-->Type String
3.name-->Type String
Your action code should look like something below.
public void onActionRaiseFire(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, java.lang.String dataObject, java.lang.String namespace, java.lang.String name )
    wdComponentAPI.getMessageManager().reportSuccess("Value in the input field"+dataObject);
Note:-
1.Make sure your using portal along with domain
Eg:-http://portal:50000/irj/portal--->wrong
      http://portal.domain.com:50000/irj/portal--->right
2.EPCF level should be 1.
3.Check whether both applications run on the same domain.Sometimes portal eventing does not work between cross domain applications.We should do domian relaxing in order to achieve this.
Thanks & Regards,
Lokesh Kamana

DeBugginng The WebDynPro Application

Dear Gurus,
Im new to WebDynPro for Java , i want to know to debug the application , please any one of you can explain inn detail.
what is the difference NWDS and NWDI?
Thanks in advance,
Phani

Hello Phani,
To be able to debug within a running Webdynpro application, you must activate debugging of the server processes of J2EE engine.
This will be done in J2EE engine View.
Follow:-
a) Window --> Show View --> Other and then select J2EE --> J2EE engine.
Choose ok to confirm your entries.The system displays a view containing status information about the running J2EE engine.
b) expand the tree display fully until you can see the actual server processes.
c) Right click the server node and then choose Enable Debugging of Processes from the context menu.
Now, Setting a Breakpoint:-
a) Choose the place where you want to set the breakpoint. Right click on the marker bar, frame next to the line of code to open the context menu and choose add breakpoint (highlighted blue dot will appear)
Hope this helps, with respect to debugging.
NWDS:- SAP NetWeaver Developer Studio is used as an integrated development environment (IDE) which incorporates NWDI. The SAP solution is designed so that the developer can perform almost all his tasks within the development environment. Access to separate interfaces and the relevant services is only required in exceptional cases such as when having to adhere to a role concept with a manager for transporting applications. SAP NetWeaver Developer Studio is based on the platform of the Eclipse open-source development project. Using its plug-in mechanism, it supports a variety of development tasks and perspectives of the individual development objects.
NWDS is just a development environment with all robust development tools.
It can run j2ee,j2se and sap applications also.
It is an interface to access NWDI services and applications
NWDI:- NWDI is Netweaver Development Infrastructure.
NWDI provides an infrastructure to develop Java applications on netweaver platform and is responsible for versioning,building and lifecycle management of these applications developed.
It has mainly three components :
DTR(Design time repository) : for versioning of any file altered.
CBS(Component build service) : for building application in central build environment.
CMS(change management service):to transport and setup logical landscape.
