Problem show web dynpro in EP, with iViews

Hi all,
I'm working with Sap Netweaver Developer Studio Version: 2.0.4 and with Web AS j2ee 6.30.
I have make an Email web service in Web dynpro with Netweaver Developer Studio and the deploy is good. I can show in the navigator of internet in:
"http://sap470:50100/webdynpro/dispatcher/local/WebDynpro_EmailWS/EmailWSApp"
I have make the application in the host "sap470" but my EP 60 SR1 i have in another machine(Netweaver).
In the portal i have created a system for Web Dynpro, but i don't know sure if i have put the WAS where the application web dynpro run or where run the portal.
I have put the WAS of application web dynpro where it run, but i am not sure that put in the path, i have put /webdynpro/dispatcher. I have created the iView in the EP, a page and rool, and i have assiciated the web dynpro to this iView.
In the propieties of iView, i have put:
Name of application: Name of the application web dynpro.
System: System that i have create before.
Name of Area: This option i'm not sure that put. Any idea?
Type of Web dynpro: Java
When i go to presentation get a error.
Any idea?
Thanks in advance

Hi,
Since the exception says "Are all referenced components deployed and available on the engine?"
Check wether any DC is used as a used DC in the webdynpro component which you are deploying.
If any used DC is available try to deploy that DC in the server and then deploy ur webdynpro application.
If all reference DC's are avialable in server, still if you get this error try to rename the component and reload+rebuild the project and deploy it.
Hope this helps you...

Sequencing Problem in Web Dynpro ABAP

Hi Web Dynpro (ABAP) Guru's,
Can anyone tell me how to read a parameter from the WDA url in my view? The situation is like this: My WDA is being rendered in the Portal EP 6.0 as an iView. When my WDA is called the portal also appends in the URL the plant number. I want to grab that plant number and use it in my view to show some default data.
As per other weblogs/forum posts I defined a parameter "PLANT_NO" in the "Default" startup plug of my Main window. I'm using the Get_Data method to read this parameter in the plug. I'm able to read the URL parameter here and so far it is good. Read below for the problem..
If I understand the order of operations correctly, doesn't the views get created, then the default plug code is run, then the views are placed on the window and then shown to the user. Since my views are created before my default plug is run I DO NOT get the URL parameter value in the WDDOINIT of my view. When I debug the application, the WDDOINIT of the embedded view gets called before the Default startup plug. Am I missing something here?
If someone can tell how to read the URL parameter in the WDDOINIT (instead of Default Startup) of the view I could default in the data I want to display. OR any other suggestions to get past this problem would be appreciated.
Does this make any sense and does anybody have an idea of where I could find some info about how to do this?
Thanks much for your help. Points will be awarded.

Thanks Klaus for the response.
I don't want to read the parameter from the default plug, but need to access the URL parameter and display default data in my view. Let me explain the scenario:
My Web dynpro application is called from the Portal. The Plant number is passed in the URL as:
http://...../sap/bc/../../<Web Dynpro Application name>?PLANT_NO=0012
I want to show Material Stock values in the view for Plant "0012". To access this value I've defined a parameter with same name (PLANT_NO) in the default startup plug of my main window. I get access to the URL parameter through this plug parameter.
I have only ONE view embedded in this window where the Stock values are selected from table MARD for the specified plant. I want to get the plant value from URL in my WDDOINIT method to make this selection from database. I'm then binding the results to the view table UI element. My problem is that the URL parameter is read in the Default plug, but the data selection and view binding happens before in the WDDOINIT method where I don't know the plant.
Again, I don't want to read the plug parameter, but I want to get the URL parameter (PLANT_NO) and then render the view based on the data selected for this parameter. Please let me know how this can be achieved by reading the URL parameter in WDDOINIT method (Constructor) so that it can be used subsequently in the application.
Thanks for your help and looking for a resolution.....

Problem in Web dynpro Java appl deployment

Hi Experts,
We are in the live environment and after successful QA testing, all the applications were deployed through SDM. In SDM log everything shows as deployed successfully.
For one where in the web dynpro screen shows exception message as:
failed to create or init instance of model <modelname> in scope application_scope with instanceId null.
All MSS and HR users are getting affected.
EP7.0SP11 and ECC6.0
Thanks,
Sonali.

If you are sure that QA testing was correct and the application was working fine.. I would say in Prod env after deployment please restart /bounce the Java Server.. this will fix the problem
Also One thing I can think of is FPM configuration in Portal(PCD) .. make sure your config in Prod is same as QA . It could be the roadmap or the perspectives are different

Show Web Dynpro as a Pop up on CRM Web-gui from ABAP Call

Hello Everybody,
i have a created a Web Dynpro Application in Z'* naming Space and want to show this WD as a POP up on the CRM Business Partner.
Step by Step Description of what I have done.
1) Want to change the Business Partner Addresse on CRM page ( Change Addresse and Press Enter).
2) A User-Exit 'EXIT_SAPLSZAR_001' has been Implemented to do Addresse Validation and select the Addresse which match the Addresse Search and show the data as a Pop-UP ( this Functionality work on SAP Gui perfectly).
3) When the User comes from Web gui then naturally shows an Error, so i have created a Web Dynpro and try to call it with Function Module 'PRGN_GENER_EXECUTE_URL'.(Error: Frontned Error).
Question: How can I call my Z* Web Dynpro as a Pop up from my User Exit without closing the CRM gui.
Thank you very much.
Regards

-     Get element at lead selection for context node FLIGHTINFO
-     Get CARRID and CONNID
-     Fill an internal table with all datasets from database table SFLIGHT, who meet the constraints for CARRID and CONNID.
-     Navigate to context node FLIGHTTAB
-     Bind the internal table(having all standard fields of sflight ) to the context node FLIGHTTAB ( having those 6 attributs).
4) On action GO ->Implement the invocation of Method " FLIGHTTAB_FILL".
5) I have mapped node FLIGHTTAB to context of OUTPUTVIEW. Display table on view OUTPUT_VIEW (for this i hav used code wizard).
Problem: after entering values of connid & carrid I m getting proper entries in internal table. but output view is not at all trigger (although i have created plugs). Is it necessary that while binding internal table with context node FLIGHTTAB should have same no of fields (i.e. in this case 6 )?
I am a fresher, My concept of bindings and cardinality are not so clear so can anybody help me out?
Thanx in advance for replying.

Hi johnright ,
    No i dont think it is necessary that while binding internal table with context node should have same no of fields as the internal table . You might get some improper values in the corresponding fiels but it will not lead to any error.
In your OUTPUTVIEW once you created the table UI element in layout and you bind it to FLIGHTTAB node you dont have to use any code wizard method to display the values. If the node contains values it will display automatically. (in your case you are filling it in step #).
Check :-
1. In your On action GO after filling the table you are firing the out bound plug :-
    WD_THIS->FIRE_INITIAL_OUT_PLG(
2.All outbound plug and inbound plug are link properly and every thing is ACTIVATED.
If still unable to find the error try to debug method wise and find where the error occurs and reply to us.
Binding:-
In web dynpro ABAP you will not able to get any value of any variable outside of any method. Here we use context node which is referrence that we create reference to any particular structure we required. Now to hold the values you need to bind
the values of your internal table to the context node.
If the node is in view then its values are visible to all the local method of the view.
If the node is in component controller then the you bind a value to the node from one view and you can get it in another view.
Remember binding and mapping are not same.
Mapping is done between node like inthe second scenario i have explained you need to create a node in view controller and then you need to map it to the corresponding view of component controller to send values across view.
cardinality:-
Each node contains data fields that represent one of the following:
    An individual instance of an object type
    A table of instances.
This property of a node is known as its cardinality of table of instances.
If you need table instance :- 0..n or 1...n
   In case of 1...n one default value is created. generally we use this as mainly we need to work with table.
In case you need a individual instance of a object or like you want value like a structure only :- 0...1 or 1....1.

Problem following Web Dynpro tutorial in NetWeaver CE 7.1

Hi all,
I have followed a training at the SAP Training Centre in Belgium, and back from this training I installed the NetWeaver CE 7.1 on my computer.
I have followed the "Developing your first Web Dynpro application" tutorial step-by-step, I have compiled it and deployed it on the server, but I'm having trouble when trying to run this "Welcome" project: I get an error:
500   Internal Server Error
SAP NetWeaver Application Server/Java AS
Failed to process request. Please contact your system administrator.
Error Summary

Any idea of what causes this problem?

I have found the problem: the server only supports JDK 5 and I was compiling with JDK 6. I have changed the compiler version and now it works fine!

How to Pass Java Objects between Web Dynpro and Java SAP iViews

Basically I have an SAP web dynpro iView that I do stuff with and I want to pass an object to another iView which is just a regular Java iView. From what I've read and tried, I can't just stick something in the session object and hope that the Java iView can pull it down the other end. I had a dream that it was possible (seriously).
Anyway, are there any possible solutions around? Please advice and share you throughts. I will try to dream about it again tonight and see if its really gonna work this time.
thanks for your help in advance

There is no easy way you can pass objects other than those supported by express such as String, map, list etc.
Though not advised, you can create a class with static variables to handle the storage of such java objects during transition between form and workflow. You will need to somehow identify the objects uniquely .

PDF form problem in web dynpro

Hello Everybody,
I have some problem with PDF form in web dynpro application.
I have used T layout view set. On top view i put one image. On left view i have tree element. On right side i have all other elements.
Right side, different views are displayed depending upon the option chosen from tree. But, when I opened view containing Adobe form and then try to choose any other options, Internet browser gives system error and browser closed.
What should be the reason behind this?

Graphics rendering problem in web dynpro

Hi all,
I have a problem using BusinessGraphics in my web dynpro application. I got the "Graphics Rendering Problem". Reading some foruns, Ive read in some thread that I have to have 5 files under my igs/conf folder of SAP installation, but I have only 2 (gwfchart.tpl and xmlchart.tpl).
One proposed solution is to apply one patch to my igs server.
My question is....
- How do I dowload the patches ? From where ? I couldnt find a download link.
Thanks in advance,

Hi,
the corresponding note for the IgsUrl paramter mentioned by Rich is <a href="http://service.sap.com/sap/support/notes/704604">704604</a>.
I think you should check this first before you upgrade your IGS installation. Note <a href="http://service.sap.com/sap/support/notes/931900">931900</a> shows you how to find out the IGS patchlevel. Then you see if your IGS is running (correct) and maybe an upgrade is needed also.

Pushbutton Problem in web dynpro

hi there,
i have a sap standard web dynpro. in the portal i have the UI elements tree to personalize the dynpro.
there is a part where i have 2 push-buttons:
Pushbutton 1
Pushbotton 2
by default Pushbutton 1 is activated. Now i want to hide Pushbutton 1 for the user. So far so good, i can do it in the UI elements tree and change it.
The Pushbutton 1 now is hidden. BUT: i want to have Pushbutton 2 activated automaticly. Now the pusbutton is not 'ON'.
how can i achive this with the UI elements tree control in Portal. I am NOT a JAVA-developer, i have no idea about web dynpro, i am coming from abap side. so i DON'T want to modify the web dynpro.....i need a way to do it with the personalization function in portal.
reg, Martin

Hi,
I assume that your requirement is to show one button at a time button1 or button2.
create 2 context attribute of type Visibility under uielementdefinition.
bind one of the context to button1's visibility property and the other to the button2's visibility property.
Now, in your code as per your condition, you can set the visibility as
wdContext.currentContextElement().set<visible1>(WDVisibility.VISIBLE);//To Show
wdContext.currentContextElement().set<visible1>(WDVisibility.NONE);//To Hide
