How to learn web dyn pro

and now about WD ABAP
1) Web Dynpro ABAP
As the name suggests Web Dynpro for ABAP uses exactly the same meta model as its cousin Web Dynpro for Java. A Web Dynpro component, a Web Dynpro view, a Web Dynpro model, a Web Dynpro controller have the same semantics both for ABAP and Java. The main difference is the designtime environment, the development infrastructure and the runtime environment.
The designtime environment is properly embedded in the ABAP Workbench where Web Dynpro artifacts are simply a new category like BSP applications or classical dynpro based applications before. Also no surprises regarding the development infrastructure. The correction and transport system keeps track on all changes that are done, versions them and helps to propagate the Web Dynpro application from development to production like you would do with ordinary BSP or dynpro-based applications.
Last not least the execution platform is the ABAP server that produces application content ready to be integrated in the NetWeaver Portal seamlessly. Features like portal eventing can be used between applications written in ABAP or applications developed with Java.

How to handle exceptions in web dyn pro

Hi Frndz....
Can any one kindly xplain how to handle exceptions in web dyn pro..like we hav exceptionhandling in java ....so is there any for NWDS
THANKS & REGARDS
Rajesh

Hi,
Web Dynpro Java is basically java only.i.e You program in java. Hence exceptions are supported in the same way as in java i.e. via try,catch and finally block.
Additionally,
In 04/04s if you create a method in any controller in web dynpro you cann't specify exception that can be thrown in the method. This is now possible in new programming web dynpro model in CE.
Hence when creating a method you can also specify custom or core java (lib)excetions.

Deploying ABAP Web Dyn Pro application in a portal iView

Hello,
Our goal is to Deploy Web Dyn Pro application to public internet user and at the same time we want to keep the ABAP Web Application server that host Web ABAP Dyn Pro application behind the firewall so that no one can directly access the ABAP WAS over the internet. To do this we are planning to deploy the ABAP Web Dyn Pro application with in a portal iView where the portal server has anonymous access to the internet user.
The question is when we embed the ABAP Web Dyn Pro in a portal iView, does the web browser directly talk to the ABAP WAS? If so, is there any other method where we could keep the ABAP WAS secure and give the public access to ABAP Web Dyn Pro application.
Thanks,
Vimalan

Hi Vimalan,
<b>I'm assuming you use some kind of a reverse proxy in front of the portal server</b>.
Here how it goes:
1. Create a WD ABAP AppIntegrator iView in the portal.
2. The iView will use a system that holds the ABAP server details (host:port and protocol)
3. The system will be configured to have the host:port and protocol of the reverse proxy server.
4. On the reverse proxy server, create a rule that will forward all URLs with the template of <i>/sap/bc/webdynpro/</i> to the real host:port and protocol of the ABAP server. This way you achieve what you intend to do.
Hope this helps,
Natty

Find the missing Authorisation Object in the WEB Dyn pro applciation

Hi,
We are having the ECC6.0 with Enterprise portal. in EP we are running the application with some webdynpro
there are some missing authorisation when running the application
how can we track the what all authorisation is missing / checked for the web dyn pro
is there any way Like SU53 in the WEbdyn pro or any other method to check ?
all the web dynpro are custom developed
Thanks & Regards
Virandra Sharda

Hi,
SU53 dump may not work for the authorization issue as it provides last authorization check failed details.
Take trace by ST01 transaction. It will provide you the authorization check details..
Where Return Code (RC) will be 4(RC= 4), there user is facing authorization issue...
Try to find the error from from the first authorization check failed details..
There may be some false authorization check failed details, what is not required for the perticular work.
This kind of error comes due to program error. So you need to test the access by adding the authorizations.. try to provide minimum authorization to solve the issue.
Regards,
Sandip.

Web Dyn Pro development

Dear Experts,
Seek your kind advise on the following:
We have developed a Web Dyn pro object which has created a URL. We are able to access the screen through directly entering the url in the browser. However, as you would know typing the extra long URL is not the preffered way. hence i wish to launch this url through a click on the web screen of the SAP CRM.
I understand the 'transaction launcher' could be helpful but I dont know how. Would be heavily obliged for some tips on how to proceed ahead.
Thanks and regards, in advance.

Thanks a ton.

Interactive report in Web Dyn Pro

Hi.
How to do the Interactive Report in Web Dyn Pro Application.
In selection screen i give the VBELN data.
Based on VBELN i want display VBAK data First.
If i am double click on the Sales Document Number of VBAK then i want display the VBAP data.
Thank You.

Hi Krishna,
Try going through this [example here|http://****************/Tutorials/WebDynproABAP/Modalbox/page1.htm]. The application has 2 views created, one for input screen for entering customer number and other for displaying the sales order details for the chosen customer. The user enters a customer number on the main view & clicks on a button to fetch the data. The system then displays the corresponding sales orders of this customer in a pop up window. The user then selects 1 sales order from the popup window and presses on another button. It would then go back to the main view & display the corresponding sales items for the selected sales order number.

Uday

Text/Caption in Web Dyn Pro? (Newline possible?)

Is it possible to add a new line for text in caption in web dyn pro?
In Java, I tried storing the string as "Result.\nPass" but it seems when being displayed, the new line is not shown but it is only shown in one whole line.
Any advise?

Hi
Good problem is solved.
Your question usage of setLabel? What label is being set when you refer to "currentContextElement()" ?
1Actually for your concern I did one test in my NWDS ,Its a wrong naming convention thats why u confused.
(instead of label i have to use say InputCaption because label is standard used by framework or its common )
2. I have created one context attribute named label and one UI of TextView ,associated its value property to
this context.
and accessed this through currentContextElement()
Best Regards

Web dyn pro+ALV

Hi all,
I am using alv in web dyn pro.
I want Drop downs in alv list.
Eg: alv is displaying carrid,connid,price,and etc.,
i want carrid and connid as read only drop downs.
Regards,
sarath

Hi Sarath,
set_attribute_value_set method is used to set dropdown values to an attribute and not to the node.
If you want to use this specific method for setting dropdown values, Create an attribute in the node 'DROP' say drop_down and then do the following.
METHOD dd_country.
DATA: lx_current_controller TYPE REF TO if_wd_controller,
lx_node TYPE REF TO if_wd_context_node_info,
lx_element TYPE REF TO if_wd_context_element,
ls_value TYPE wdy_key_value,
lt_value_set TYPE wdy_key_value_table,
lx_current_controller = wd_this->wd_get_api( ).
Get the Values to that need to be set as dropdown,
Build the values set internal table. by doing the below.
CLEAR ls_value.
ls_value-key = ls_t005t-land1.
ls_value-value = ls_t005t-landx.
APPEND ls_value TO lt_value_set[].
Set the dropdown.
lx_node = wd_context->get_node_info( ).
lx_node = lx_countries_node->get_child_node( name = 'DROP' ).
lx_node->set_attribute_value_set( name = 'DROP_DOWN'
value_set = lt_value_set ).

Is Auto-refresh feature available for tables in web dyn pro???

Hello Experts,
I have a requirement as explained below..
There is a table which has few rows, which are populated on launch of a particular screen..now table needs to be refreshed without reloading of page or press of a button (i.e without any user action)..
is there any fearure in Web dyn pro which facilitates this requirement???
Thanks in advance..
thanks & Regards,
Hampanna Kamatar

Hi Hampanna,
I guess you can use the TimerTrigger. This will be useful in your case.
The TimedTrigger UI element is used to execute a controller action periodically with a defined delay.
TimedTrigger is currently invisible (like InvisibleElement), thus it ignores both its tooltip and its visibility. Nevertheless it occupies a cell in certain layouts like MatrixLayout. To use a timed trigger, you have to assign an action to the onAction event and set the delay property to the desired delay in seconds.
There are several ways to turn off a timed trigger. The most convenient way is to disable the assigned action (like you would do with a button). Other possibilities are setting the delay to 0 or disabling the timed trigger like any other UI element.
Caution: Triggering the action rudely interrupts user interactions!
So what you can do is asign a action and write the code to reload teh data in that action. Set the delay you require in seconds. In case later you want to switch of the timer you can easily do that.
Check these API:
http://help.sap.com/javadocs/nwce/current/wdr/com/sap/tc/webdynpro/clientserver/uielib/standard/api/IWDTimedTrigger.html
I hope this will solve your issue.
Thanks and Regards,
Pravesh
