Time Manipulation in BPEL
Hi,
In order to implement a specific business rule, the following
technical problems need to be solved:
-- How to get the current system time and keep it as a process
variable.
-- How to make a comparison of the two time variables that the
interval is less than 5 min or not.
Is it to implement this using BPEL based on ODE or not? Please give
some suggestions. Thanks very much.
Best Regards
Lei Wang

For some reason, it appears that that page got lost on ode.apache.org. But
there is still a copy here:

Hi,
The time manipulation operations I need are provided by the XPath 2.0
extension of ODE. However, I am interested in how to add Java implemented
XPath functions to ODE. Is there any detail information about how to
achieve this?

Hi,
BPEL uses XPath as expression language, and ODE also supports XPath 2.0
powered by Saxon. Thus, you can use the XPath function current-dateTime
[1]. Regarding the date comparison, XPath provides some helper functions
but I doubt that they are fully implemented by Saxon. But since you could
add your own XPath functions (implemented in Java and then put to ODE's
classpath), you would overcome these problems.
