Helo,
Thanks for your replies, sorry about the delay in replying - I've been
travelling. I'm still confused as to how do to what I wish (BTW the code is
from Java -> Scripting language). Here's a concrete example :
---
* An authorised user submits a script that will be run in the future the
script looks like (example in Jython):
<a load of import statements and so on>
def getOrderData(order_number, order_submit_auth_code):
<blah, blah, blahh>
__check_order_auth(order_submit_auth)
#dctOrderDetails is a dictionary which contains key value pairs contiang
order information.
return dctOrderDetails
def __check_order_auth(auth_code):
<blah, blahh, blaaahh>
return tOrderAuthorised
* In the future the system receives a request to run that script by callign
the function getOrderData with the parameters order_number=123456 and
order_submit_auth_code=98765
* The framework then calls the getOrderData function, receives teh dict -
converts it into a Java friendly instance (somewhere previously it was told
that this is what it would be getting) and returns it to the caller.

So that would be about it, I can get something to work by specifying a
format which the scripts must be in and passing the variable in. Therefore I
could modify the script to register the parameters as variables and simply
insert a call to the function right before the function deceleration. Such as :
---
registerBean(passOrderNubmer, new Integer(123456));
registerBean(passOrderAuthCode, new Integer(98765));
I can then modify the execution script so that it now has:
<a load of import statements and so on>
getOrderData(passOrderNumber, passOrderAuthCode)
def getOrderData(order_number, order_submit_auth_code):
<blah, blah, blahh>
__check_order_auth(order_submit_auth)
#dctOrderDetails is a dictionary which contains key value pairs contiang
order information.
return dctOrderDetails
def __check_order_auth(auth_code):
<blah, blahh, blaaahh>
return tOrderAuthorised
---
That way I can execute the scripts by calling a simple eval. Does anyone
know if that would work (I've given up with the apply call)?
Thanks for your help.
Cheers,
Neil
