Shows how to use <if/> construct to implement where user need to verify a logical condition.
BPEL If-Else activity executes the process based on the condition defined in <condition/>. Comparing to pick activity, if-else activity depend on a logical condition rather on an event.
<if> <condition>number($tmpVar)=number(2)</condition> <assign name="assignError"> <copy> <from> <literal>Worked</literal> </from> <to variable="myVar" part="TestPart"/> </copy> </assign> <else> <assign name="assignZut"> <copy> <from> <literal>Failed</literal> </from> <to variable="myVar" part="TestPart"/> </copy> </assign> </else> </if>
<condition/> inside <if/> is used to implement the logical condition. Normally a XPath expression is used. <else/> is used to implement false case.
In the above example, value of tmpVar variable, is converted to a number and it's checked against 2. <condition>number($tmpVar)=number(2)</condition>
Based on the tmpVar value, "TestPart" element value in myVar variable will be "Worked" or "Failed".
Note - Apache ODE runtime has default support for http://www.w3.org/TR/xpath/, where
the number($var) is defined.
