How to create a node with attributes at runtime in webdynpro for ABAP?

Hi Experts,
         How to create a node with attributes at runtime in webdynpro for ABAP? What classes or interfaces I should use? Please provide some sample code.
I have checked IF_WD_CONTEXT_NODE_INFO and there is ADD_NEW_CHILD_NODE method. But this is not creating any node. I this this creates only a "node info" object.
I even check IF_WD_CONTEXT_NODE but i could not find any method that creates a node with attribute.
Please help!
Thanks
Gopal

My code is like the following:
TYPES: BEGIN OF t_type,
            CARRID TYPE sflight-carrid,
            CONNID TYPE sflight-connid,
         END OF t_type.
Data: i_struc type table of t_type,
dyn_node   type ref to if_wd_context_node,
rootnode_info   type ref to if_wd_context_node_info,
i_node_att type wdr_context_attr_info_map,
wa_node_att type line of wdr_context_attr_info_map.
      wa_node_att-name = 'CARRID'.
      wa_node_att-TYPE_NAME = 'SFLIGHT-CARRID'.
      insert wa_node_att into table i_node_att.
      wa_node_att-name = 'CONNID'.
      wa_node_att-TYPE_NAME = 'SFLIGHT-CONNID'.
      insert wa_node_att into table i_node_att.
clear i_struc. refresh i_struc.
select carrid connid into corresponding fields of table i_struc from sflight where carrid = 'AA'.
rootnode_info = wd_context->get_node_info( ).
rootnode_info->add_new_child_node( name = 'DYNFLIGHT'
                                   attributes = i_node_att

dyn_node = wd_context->get_child_node( 'DYNFLIGHT' ).
dyn_node->bind_table( i_struc ).
l_ref_interfacecontroller->set_data( dyn_node ).
I am trying to create a new node. That is
CONTEXT
- DYNFLIGHT
CARRID
CONNID
As you see above I am trying to create 'DYNFLIGHT' along with the 2 attributes which are inside this node. The structure of the node that is, no.of attributes may vary based on some condition. Thats why I am trying to create a node dynamically.
Also I cannot define the structure in the ABAP dictionary because it changes based on condition

How to integrate WebDynpro for ABAP application with SAPEnterprisePortal7.0

Hi WebDynpro for ABAP Experts,
We developed an WebDynpro for ABAP application on R/3, and now we are planning to show this as an iview on SAP Portal EP7.0 (SAP j2EE Engine--Java stack). is it possible to integrate this application with portal?
If so can you proviode me the way how can we achieve this?
ADV Thanks
Regards
Phani

Hi Alex,
Thanks for your response.
I already created the system object R/3 Backend.
Actually some WebDynpro java applications/iViews are currently running on Portal. and the developers developed these in NWDS and deployed the .sca files on the Portal server and we created Webdynpro for java iViews.
but now the requirement is creation of webDynpro for ABAP views.
The developers developed WebDynpro for ABAP on the R/3 system. So what are the parameter values we need to give at teh time of creation of WebDynpro for ABAP iview like the Namespace, Application name etc which are mandatory values and how the Portal server detects the application, this means no need to deploy the application on the Portal server?
Shall we need to maintain any JCo Destinations or not?
Pl share your ideas.
ADV Thanks

Phani

How can we benefit from WebDynpro for ABAP over Normal ABAP

Dear Guru's,
Please guide me what are +Ves of WebDynpro over Normal ABAP. Once all Applications are developed how can we organize them. For Example In SD module there is sequence of Tcodes to be executed this is true for all modules . Is there any concept involved in this new technology.
For What purpose we can suggest someone to implement in an Organization.
Many Thanks in Advance.
Regards
Ram

Hi Ram,
Here Are some comparisions I made w.r.t Webdynpro for ABAP (also some benifits over Java):
1     "Pros:it will be easier to move your development project through the system landscape if both the UI and business logic are in the same development environment.(Update: This is is less of a concern now that CTS+ lets you bundle your WD Java UI developement with ABAP development objects into a single transport, with SPS13. )
2     tons of custom ABAP business logic is easier to access via WD for ABAP
3     WD for ABAP has a code wizard, so easy to build
4     SAP List Viewer and ALV handled better
5      The biggest thing is the NWDI. Most of the SAP customer have ABAP stack, but not everyone has the Java stack. To develop WD Java you need to set up the NWDI envrionment, like SLD, CMS, CBS, DTR, etc. which is a huge effort if you don't have them in place. While for WD ABAP, the environemnt is normally there as given for most of customers if they have the right version.
6     If your business is in SAP system, I would prefer WD ABAP. There are many WD components available in WD ABAP like select-option, Alv table, F4-help which are not available in WD Java. Beside in WD ABAP you can deal the context node in form of internal table which is much more performant than dealing with the contextelement which is the case for WD Java.

How to configure Webdynpro for ABAP Launch for Travel Request workflow UWL

Hello,
We are on SAP ECC 6 EHP4, SAP Netweaver 7.01 SP5, for portal BP1.41. When we are running travel request in this new Webdynpro for ABAP in UWL it will lead from an attachment to PR05 trx. I would think that it would gve another screen where the manager can check a travel request. Is the standard SAP solution leading to this trx. PR05? We have tried to customize the task 20000189 in SWFVISU but it doesn't give us any results.
I would appreciate if you can give me an advice whether SAP standard solution will lead to PR05 or is there any other options what we haven't discovered yet. Otherwise we have to start customize it.

How to read some images from file system with webdynpro for abap?
Thanks a lot!

Hello Tao,
The parameter
icm/HTTP/file_access_<xx>
may help you to access the pictures without any db-access.
The following two links may help you to understand the other possibilities as well.
The threads are covering BSP, but it should be useful for WebDynpro as well.
