The following steps describes how to define an invoker for a presentation
node to call a business process.
- Create an invoker for calling the business process. See Creating an invoker for detailed steps.
- Double-click the line that links the presentation node
to the business process node. The Properties dialog of link box
pops up. Since you have already defined the presentation node and
the business process node, some fields are already filled with certain values.

- From the Invoker ID field, select an existing invoker
ID or type in a new invoker ID.
- Click OK to close the dialog box and make
your settings effective.
- The properties file and Java™ file of invoker will be generated.
Notes: - When you change the invoker files outside the Graphical Builder, you must
keep the resource consistency.
- If you want to restore a invoker, you must backup the invoker property
files and the invoker class files.
