You can create some composition nodes by dragging and dropping the
existing resources into the Graphical Builder.
Here is a demonstration of
how to create a business process node with existing resources.
From the Package Explore view, select a BPEL file that you have
created.
Drag and drop the BPEL file into the Graphical Editor. You probably see a yellow left arrow between the business process node
and the presentation node. This means that you haven't define the invoker.
You can put your cursor on the yellow left arrow and see the help information
that indicates the error message.
Note: When you see a yellow left arrow symbol
or an exclamation mark symbol in the Graphical Editor, these symbols indicates
you haven't pass the validation of the Graphical Builder. You can always put
your cursor on the symbols to get the help information.
You
can also create a presentation node by dragging and dropping a Struts Graphical
Builder file into the Graphical Editor.
You can also create a Single
Action EJB node by dragging and dropping an ejb-jar.xml file into the Graphical
Editor.
