The Palette will show only the BPEL 2.0 elements that are supported by
the Design view. However, you are free to go to the Source view to manually edit
the BPEL files (If you already know BPEL).
As already mentioned earlier in this book, the BPEL elements supported by the
Design view may vary from the BPEL support provided by the JBI runtime. Hence
most of the time, even if the Design view does not support a particular BPEL 2.0
element, you can still get it working in the process. The following figure shows the
BPEL activities palette:
Both the Basic Activities and Structured Activities nodes are not expanded by
default. Click on the [+] icon to expand the node.
When you drag-and-drop a Palette element into the BPEL diagram, it becomes a
BPEL activity. Click on any palette element and drag the element over the BPEL
diagram. Some point in the BPEL diagram will be highlighted in an orange color.
You are supposed to drop the elements only in those areas. For instance, you can
drag-and-drop an Invoke element only after a Receive element.

Web Service Activities
To be instantiated, an executable business process must contain at least one
or activity annotated with a createInstance="yes" attribute.
This is a general rule for creating an instance of your process.
