122 Using BPEL Processes in WebSphere Business Integration Server Foundation - Business Process Integration and Supply Chain Solutions
The icons given in the table are what appear in the process area of the canvas.
The icon you would choose in the activities palette looks like the small icon in the
top center of these icons.
Figure 5-26 shows the invoke activity to demonstrate this. You can see that the
small icon on the right, which you choose in the activity palette, is the same as
the small upper center of the icon that appears on the process area

Table 5-4 WebSphere Process Choreographer activities
The invoke activity performs an operation. The operation is defined by
a partner link and may be synchronous or asynchronous.
The receive activity waits for an external input to the process before
continuing. The operation supported by the receive activity is defined
by a partner link.
The reply activity sends a message to the partner defined by a partner
link. This is typically used in processes that need to return a message
to the partner that instigated the process.
The pick activity waits for an incoming message and selects a path
appropriate to the first message received. A time-based path can be
configured to manage situations where no message is received. A
partner link is associated with each message path.
The staff activity delegates a task within the process to a human. The
user interface in this case is either a custom application based on the
process choreographer API or the Web client provided that comes with
WebSphere Business Integration Server Foundation.
The transformer activity maps the contents of one or more message
types to the contents of another.
