After you add BPEL activities to a diagram, you need to configure them. You can do this using either the Property Editor dialog boxes or the IDE's Properties window. Note that Property Editor dialog boxes are available only for some elements.
To open the Property Editor for an element, do one of the following:
Right-click the element and choose Edit.
Double-click the element.
To open the Properties window for an element, right-click the element and choose Properties. The properties for this element are displayed in the standard IDE's Properties window. If the IDE's Properties window is not open, choose Window > Properties from the main menu (Ctrl-Shift-7).
