SOAP-encoded arrays are supported in BPEL projects that use version 2.0 of the BPEL specification. The following example shows a sample assign activity with a SOAP-encoded array in a BPEL 2.0 project.

<assign name="Assign_1">
   <copy>
      <from>$inputVariable.payload</from>
      <to>$Invoke_1_echoArray_InputVariable.strArray/JavaLangstring[1]</to>
   </copy>
   <extensionAssignOperation>
      <bpelx:append>
         <bpelx:from variable="Invoke_1_echoArray_InputVariable"
            part="strArray">
            <bpelx:query>
               JavaLangstring[1]
            </bpelx:query>
         </bpelx:from>
         <bpelx:to variable="Invoke_1_echoArray_InputVariable"
            part="strArray">
         </bpelx:to>
         </bpelx:append>
    </extensionAssignOperation>
   </assign>

The following example shows a sample invoke activity with a SOAP-encoded array in a BPEL 2.0 project.

<invoke name="Invoke1" partnerLink="FileOut"
   portType="ns3:Write_ptt" operation="Write"
   bpelx:invokeAsDetail="no">
   <toParts>
      <toPart part="body" fromVariable="ArrayVariable"/>
   </toParts>
</invoke>
