About the BPEL Mapper
See Also
The BPEL Mapper provides a framework for processing and directing business process data.
This framework consists of the following components:
- Menu Bar. The menu bar provides all BPEL Mapper XPath functions you use to create BPEL mappings.
You can also enhance or extend BPEL mappings by incorporating predicates that consist of XPath functions.
- Source tree pane. The source tree pane contains a tree component that provides access to a business process's data variables.
- Mapping pane. The mapping pane contains a canvas for creating BPEL mappings.
When you select a function in the menu bar, a function box appears in the mapping pane.
If the function accepts any arguments, then the left side of the function box has one connector for each argument.
If an argument is optional, then a question mark appears after the argument name.
The right side of the function box has one connector for the result.
You can use the BPEL Mapper with the following business process elements:
- Assign activity. You can define one or more copy assignments.
- If activity. You can define the condition.
- ElseIf element within an If activity. You can define the condition.
- ForEach activity. You can define the condition.
- RepeatUntil activity. You can define the condition.
- While activity. You can define the condition.
- Wait activity. You can specify the deadline or duration.
- onAlarm event. You can specify the deadline or duration.
- Destination tree pane. The tree component of the destination tree pane depends on the business process element that you are mapping.
The destination tree pane contains the following components:
- For an Assign activity, the right pane contains the same tree component as the left pane.
- For an If activity, ElseIf element, ForEach activity, RepeatUntil activity, and While activity, the right pane contains a Result node.
- For the Wait activity and onAlarm event, the right pane contains a Deadline or Duration node.
To open the BPEL Mapper window:
- Choose Window > BPEL Mapper or press Ctrl-Shift-9.
The BPEL Mapper window also opens when you select an element containing XPath expressions on the diagram.
