To Edit the Basic Activities : Assign1

1    Double-click the Basic Activity : Assign1.
      This displays the BPEL Mapper window.

2    Expand the node in the Source tree pane (the left pane) of the BPEL Mapper under Output —> Variables.
       For example, TriggerWSDLOperationIn
       A Trigger1n node appears under the TriggerWSDLOperationIn node.
3    Expand the node in the Destination tree pane (the right pane) of the BPEL Mapper under Input —> Variables.
       For example, AddWSDLAddOperationIn
       A request node appears under the AddWSDLAddOperationIn node.
4    Select the node in the Source tree pane. Drag the selection and map it to the node in the Destination tree pane.
       For example,
       a    Source tree pane: TriggerWSDLOperationIn — Trigger1n
       b    Destination tree node: AddAddOperationIn — request — attributes — MainAttribute — inetOrgPerson.uid

        Map the following:
        TriggerIn — inetOrgPerson.uid

5    Click Save All.
6    Expand the node in the Destination tree pane (the right pane) of the BPEL Mapper under Input —> Variables.
       For example, AddWSDLAddOperationIn
       a    Select request — attributes — Attributes
               i    Select person.sn.
               ii    Click String and select String Literal from the drop-down list.

            iii    Enter the values in the String Literal and map the String Literal with person.sn.
                   For example, person.sn = Joe, where sn = surname and person.cn = Jane where cn = common name

7    Click Save All.
8    Click the Design tab.

To Edit the Basic Activities : Assign2

1    Double-click the Basic Activity : Assign2.
      This displays the BPEL Mapper window.

2    Expand the node in the Source tree pane (the left pane) of the BPEL Mapper under Output — Variables.
       For example, AddWSDLAddOperationOut
       Expand response — OperationResult.
3    Expand the node in the Source tree pane (the right pane) of the BPEL Mapper under Input — Variables.
       For example, TriggerWSDLOperationOut
4    Map the following variables
       For example, OperationResult — TriggerOut
5    Click Save All.

6    Click the Design tab.
      The final output is as shown in the illustration.
