Hi, I thought this worked for me at some point, but, I now seem to have lost my ability to get any debuggable DRL error contexts via the -Ddrools.dump.dir property.

Oh no. Ouch! So the [ERR] messages I'm getting -- w/ explicit line numbers being produced (wrt to some internal DROOLS in-memory DRL representation) -- cannot in any way be x-referenced with an externalized view of the DROOLS in-memory DRL representation? Thanks for the reply Wolfgang (as always). But this seems like really bad news wrt to a newbie needing to debug their DROOLs DRL (generated from template) code. If the (generated from template) internal DROOLs DRL representation can't be externalized w/ any sort of view via the DROOLs API, Do you have any recommendation for a how a developer could "look under the skirt" at this part of DROOLs runtime? -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Wolfgang Laun Sent: Monday, November 19, 2012 1:12 PM To: Rules Users List Subject: Re: [rules-users] expectation for -Ddrools.dump.dir to show DRL error context ..

THANKS WOLFGANG!! :-)

-----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto: rules-users-bounces(a)lists.jboss.org] On Behalf Of Wolfgang Laun Sent: Monday, November 19, 2012 1:37 PM To: Rules Users List Subject: Re: [rules-users] expectation for -Ddrools.dump.dir to show DRL error context .. I'm not quite sure that I've been aboard your train of thoughts. There are compilations where you feed the Drools Builder with non-DRL files, which will induce it to produce a DRL and compile that, automatically. This is where the DumpDirOption should produce the intermediary result in that directory. If you call some mechanism using XSL and DRT to generate DRL text, which you then pass to the compiler, you've taken the responsibility to handle this DRL text. If there is a problem, you might consider writing the DRL text to a file and call the builder with this file as a DRL resource. Note: All of the above assumes I've outguessed your procedure correctly ;-) Cheers Wolfgang On 19/11/2012, Cotton, Ben <Ben.Cotton(a)morganstanley.com&gt; wrote: > Oh no.
