[rules-users] Drools Decision Table

[Riyaz Saiyed]

Hi,

 

I'm doing a POC on drools decision table. We need to develope pricing
engine for few of our products. I created xls with list of products and
their price as per drools format. When I load xls and run the rules, the
price were picked up correctly against mathing product, customer and
quantity criteria.

 

Now I want to save the executed rule so the if there is any modification
in quantity (increase/decrease), I can calculate the price again based
on earlier executed rule and not from xls.

 

I think to achieve the, I need to store the "rule" against every order
for each product. 

 

Can any one suggest me, how I can get the string representation of the
executed rule so that I can create .drl file from that string and run
the same rule again for any order modification.

 

I've looked at SpreadsheetCompiler and was able to get the string of all
the rules as a result of compile method. 

 

Note - I can not read xls again for order modification because, if in
between the price in xls has changed, the engine should still pick the
old price.

 

Thanks,

Riyaz
