Checkout 3 new BPEL Extension functions for date/time comparisons. These functions are implemented as extension functions as BPEL 2.0 (which uses XPath 1.0) standard function list does not include these. The syntax and definition for these is derived from XPath 2.0 spec (http://www.w3.org/TR/xquery-operators/). These new functions being -
sxxf:dateTime-less-than (Less-than comparison on xs:dateTime
values)
sxxf:date-less-than (Less-than comparison on xs:date values)
sxxf:time-less-than (Less-than comparison on xs:time values)
Where the namespace prefix sxxf stands for "http://www.sun.com/wsbpel/2.0/process/executable/SUNExtension/XPathFunctions" which need to be defined in the process definition.
Note that these functions can either take literal value
(corresponding to xs:dateTime, xs:date or xs:time
representation) or BPEL Variable of appropriate time.
A test case to showcase example usage of these function is
checked in driver tests. Check out BPEL Project and Composite
Application from
https://open-jbi-components.dev.java.net/source/browse/open-jbi-components/driver-tests/bpelse/xpathfunctions/DateTimeComparison/.
Copying from the test case-
sxxf:dateTime-less-than($NewWSDLOperationIn.dateTime1,
$NewWSDLOperationIn.dateTime2)
sxxf:date-less-than($NewWSDLOperationIn.date1,
$NewWSDLOperationIn.date2)
sxxf:time-less-than($NewWSDLOperationIn.time1,
$NewWSDLOperationIn.time2)
sxxf:dateTime-less-than('2008-09-29T17:15:43.68-08:00',
'2008-09-29T17:15:43.67-08:00')
sxxf:date-less-than('2008-09-28', '2008-09-29')
sxxf:time-less-than('17:15:43.68-08:00', '17:15:43.67-08:00')
