How to pass multiple values while invoking bpel process from ADF?

Question

Hi,
I want to call a bpel process from my ADF application. The bpel process is having one input parameter. I have created webservice data control by using WSDL url.
Lets say, I have an Emp multi select table. I drag and drop the data control into Emp table selection facet to create an "Invoke" button.
I am able to pass single value (lets say Empid) to the bpel process after clicking the "Invoke" button.
But, my requirement is to pass all the selected values ( as its a multi select table) to the bpel process after clicking the "Invoke" button once.
How can I achieve this?

Hi,
if the BPEL method that you access allows you to pass arrays or lists, then you can get a list of selectedRowKeys from the table, which then you use to get the value from the underlying binding or the table. This however requires some Java coding instead of directly invoking the executable on the binding layer
- you create the BPEL method in the binding layer
- from a Java managed bean you call ADFBindingContext --> get current instance and access Binding container
- OperationBinding oper = (OperationBinding ) bindings.get("method to invoke");
oper.gerParamsMap().put("the BPel argument name", value);
oper.execute();
- To access the table selected rows
RowKeySet rks = _table.getSelectedRowKeys();
  //iterate over the set of selected row keys and delete
  //each of the found rows
  Iterator selectedRowIterator = rks.iterator();
  while (selectedRowIterator.hasNext()){
    //get the first key
    Object key = selectedRowIterator.next();
    //make the row current
    _table.setRowKey(key);
    //the row is an instance of the ADF node binding class
    JUCtrlHierNodeBinding rowWrapper = null;
    rowWrapper = (JUCtrlHierNodeBinding) _table.getRowData();
    //get the actual oracle.jbo.Row object
    Row row = rowWrapper.getRow();
    ... get attribute values by calling row.getAttribute("name"); assuming you used ADF BC to build the tableFrank
