Possible London Drools Boot Camp for October

by Mark Proctor

The San Francisco Boot Camp <http://blog.athico.com/2009/03/drools-boot-camp-san-francisco-june.html> was a great success, with a fantastic turnout <http://www.jboss.org/community/wiki/DroolsBootCampSanFranciscoJune2009>. If I got enough names I could be tempted to do a London based event at the JBoss offices, probably in October. I would probably aim for this event to be just a 1 or 2 day event, dependant on the requests I receive. If you are interested, send me an email. The main idea would be to get 15 to 20 like minded people together for a day or two, where we can just discuss each others problems and we in the Drools team can help you deep dive into the Drools code.

Re: [rules-dev] Exception with Drools-XLS and Maven: "An error occured opening the workbook."

by Michael Neale

yes - I think in all cases it turned out to be munging of the XLS file (it is certainly not text ;) So I think that is what the jexcel library reports when things go badly wrong... That other error in JIRA is to do with supporting open office files (ie you get that error if you try to load up a ODS file). Is this something we can raise with the maven plugin to not mess with XLS files?

Re: [rules-dev] Exception with Drools-XLS and Maven: "An error occured opening the workbook."

by Geoffrey De Smet

By default the maven resources plugin copies resources in the encoding of the platform it's build on IRCC. It's better to lock that down on UTF-8. It even logs a warning if it's not locked down. Is that xls file a resource that's being copied?

Drools Solver homepage

by Geoffrey De Smet

Hi guys, On the drools homepage, each of the major subprojects have a homepage, for example for Guvnor: http://labs.jboss.com/drools/drools-guvnor.html Such a homepage answers a few start questions: - What is it? - What are its features? - Lets see some screenshots. - Where do I go next? => download, examples, reference manual, blog, ... Drools Solver doesn't have such a homepage yet, so when I have to fill in a link to drools solver, I sometimes fill in the blog or the reference manual or even the article on Dzone. So such a Drools Solver homepage is missing: I can create some content for it, if JBoss is willing to add a page to the Drools homepage? WDYT? -- With kind regards, Geoffrey De Smet
