Pool

A BPMN 2.0 Pool represents a Participant in a Process and does not map to any specific BPEL 2.0 element. Enterprise Architect uses Pools to represent external Participants, with which the BPEL Process communicates. These are 'black box' pools; that is, they are abstract and do not expose any details (they do not have any BPMN 2.0 elements inside them).

BPEL Properties

• Double-click on the Pool in the BPEL diagram
• Right -click on the Pool | BPEL | BPEL 2.0 Properties

Options

Fill Opacity

For a given Pool in a diagram, you can make the element strongly visible or less obvious, depending on how much you want to emphasize its significance, temporarily or for a longer period. You can apply these nuances in the display of the element by changing the opacity of the element fill.

Before setting the opacity, check that the element has a fill color.

You set the opacity using an icon from either of these two pop-up element toolbars:

• Click on the Pool element and on the icon:
  
• Right-click on the Pool element and look above the context menu:
  

Click on the icon and select:

• 100% for total opacity, where anything behind and overlapping or covered by the element is hidden
• 0% for no opacity, where the fill color is not applied and anything behind the element is fully visible
• 75%, 50% or 25% to set the appropriate degree of opacity and make the background visible but over-shaded

Notes

• A BPEL Process should not contain a Pool as its child element
• A BPEL diagram under a BPEL Process contains an implicit Pool, so it is invalid to add a Pool in this BPEL diagram to represent the BPEL Process
• Pool cannot have any incoming or outgoing Sequence Flow connectors - it can have only incoming or outgoing Message Flow connectors
