Assumptions:
- You have created a data control.
- You have created a methodAction binding for the respective operation on a page.
import oracle.binding.AttributeBinding;
import oracle.binding.BindingContainer;
import oracle.binding.OperationBinding;
import oracle.adf.model.BindingContext;
public class BindingsExample{
public BindingsExample(){
super();
}
public void invokeOperation() {
// get a handle on the bindingContainerBindingContainer
bindingContainer = BindingContext.getCurrent().getCurrentBindingsEntry();
// get a handle on the operation you want to invoke
OperationBinding operationBinding = bindingContainer.getOperationBinding("yourOperation");
// get a handle on an attribute that is bound to some component on a page
AttributeBinding yourAttr = (AttributeBinding)bindingContainer.getControlBinding("yourComponentBinding");
// put the value of the attribute in an operationBinding map
operationBinding.getParamsMap().put("yourKey", yourAttr.getInputValue().toString();
// invoke your operation
operationBinding.execute();
// check for any exceptions
if (!operationBinding.getErrors().isEmpty()) {
// handle exceptions accordingly
}
}
}
If you're dealing with complex types in the WSDL, you can update the request using the DCBindingIterator.
// cast your bindingContainer to a DCBindingContainer
DCBindingContainer dcBindingContainer = (DCBindingContainer)bindingContainer;
// get the data control iterator
DCIteratorBinding dcIteratorBinding = dcBindingContainer.findIteratorBinding("yourIterator");
// update the row with the value of an attribute bound to a page
Row row = dcIteratorBinding.getCurrentRow();
String value = yourAttr.getInputValue().toString();
row.setAttribute("DateTime", value);
