Passing values to ABAP/JAVA webdynpro appl. when workitem invoked from UWL

Question

Hai,
We are using universal worklist for invoking a workitem. The workitme may trigger a ABAP/Java based webdynpro application. I have registered the tasks associated with the workitem in universal worklist.
I have few doubts in the integration part,
1. When a workitem is clicked in UWL, I want to get some values from the workflow container and show it on the webdynpro application. In the webdynpro application I can call a function module to get the values from workflow container by passing in workitem id.How can I pass a workitem id to webdynpro application when a workitme is clicked.
2. After the user open the workitem a webdynpro application is shown on the screen. Lets assume this screen is having "Approve", "Reject" and "Exit" button. When this button is clicked how to pass that information to workflow so that the workflow flow its paths.
Please let me know how to do this.
Thanks & Regards,

Hai Chintan,
I checked the blog, and found the below code,
workflowrawdata =
    wd_context->get_child_node(
          'WORKFLOWRAWDATA' ).
  CALL METHOD
              WORKFLOWRAWDATA->GET_ATTRIBUTE
         EXPORTING
                 NAME   = 'WI_ID'
         IMPORTING
                  VALUE  = wi_id.     
I have the following doubts in the code,
1. Where I have to put this code,
2. Using which data element or type I have to declare, "workflowrawdata".
3. Should I have to declare "WI_ID" in parameter tab of Webdynpro application.
4. In webdynpro application what I did is,
a. In the context of component controller, i have created attributes to store workflow id, and some attributes to store the value from workflow container.
b. I created a view and in view context i have created attributes to store workflow id, and some attributes to store the value from workflow container.
c. I created some UI elements in the view and binded that UI elements with view context.
d. I binded view context with the context of component controller.
e. I created a window and in the view context i have created attributes to store workflow id, and some attributes to store the value from workflow container.
f. I did context mapping between window context and component controller context.
g. I added the view to the window.
h. I created a inbound plug with name "START". This creates a method called "HANDLESTART" to this method I added a importing parameter named "WI_ID" and added the below code,
data : lo_node               type ref to IF_WD_CONTEXT_NODE,
       l_cont                 type standard table of swr_cont,
       l_cont_line            type swr_cont,
       rc                     type sy-subrc,
       l_wi_id                type sww_wiid,
       l_object               type SWOTOBJID,
       lv_workitem_attributes type swr_wihdr.
call method wd_context->get_child_node
     exporting
       name = 'WORKFLOWRAWDATA'
     RECEIVING
       child_node = lo_node.
lo_node->set_attribute( value = wi_id name = 'WI_ID' ).
l_wi_id = wi_id.
Please let me know what else i have to do to get the workflow id in ABAP-Webdynpro application.
