[rules-users] [Knowledge Agent Question

[Mahalakshmi]

Hi,
Thanks so much for the info.
So then is there any way to actually add the dslr (created at runtime) files
to be detected by the program??
Because with eclipse we always need to keep refreshing the files everytime
which totally defeats the purpose of using business rules !! Until ofcourse
you have fixed set of rules!
Any other ideas?
Also is there a problem if we add multiple .dslr files to our rule base???
When I do that only the first .dslr files actually executes and the others
dont. I tried creating all the same files as .drl files and it works
perfectly fine.
Any idea why that happens??? I dont get any error stack.

Please help.

Thanks
M
