Re: [rules-users] Optaplanner with Apache Commons Collections 4.0
On 27-11-13 22:12, jonathan.labin wrote: Apache Commons Collections 4.0 has been released and has some data structures that I'm interested in using in my application. To your knowledge can Optaplanner function with version 4.0 swapped in place of 3.2.1? I am not of anyone that tried besides you. If you want to be confident it's safe, do the following: git clone optaplanner cd optaplanner gedit pom.xml // in dependencyManagement overwrite the commons-collections dependency to 4.0 and save mvn clean install // runs all unit and integration tests in about 8 minutes (without the stress test that take 30 hours but don't cover more code) If the build succeeds, its fine. I have tried this and not encountered any issues at build or run time but that of course doesn't mean they aren't there. Will the next release of Optaplanner leverage this more recent release of Collections? Probably not in the next release. IIRC Hibernate, EAP 6, etc are still using commons-collections 3.x, so it would be too early to jump to a new major release (a minor or hotfix release would be less trouble). Sooner or later, we will upgrade though. Side note: I am seriously considering of adding a guava dependency in optaplanner 6.1 and dump the commons-collections dependency altogether. https://issues.jboss.org/browse/PLANNER-209 Wdyt?

[rules-users] Fwd: [ljc] Call for Help - OSS projects
Hi Mark and the gang, Not sure whether you guys have seen this already (I’m guessing some of you must in in LJC), but if you’re looking for more London-based developers to get involved in the community side of Drools/KIE related projects, then it might be worth checking this out. Steve Begin forwarded message: From: Barry Cranford b...@recworks.co.uk Subject: [ljc] Call for Help - OSS projects Date: 29 November 2013 06:39:11 GMT To: ljc-l...@meetup.com Reply-To: ljc-l...@meetup.com TL;DR - We have had 44 LJC events this year. Woo! - We need to connect with more OSS projects for an upcoming Meet a Project event Hi All, We are nearly at the end of our year of events (we have had 44 LJC events so far this year). Our very last one of the year is a 'Meet a Project' event scheduled and are looking for some budding project leads that are going to come down and present their projects to small groups of developers, eager to find a new OSS project or similar to get their teeth into. Date: 11th December Time: 6:30 Venue:UCL, London If you are interested please reply to me directly. To give you a bit of background to these events and why we started this initiative - one thing I have observed over the years, both as a recruiter and as a community leader is that there is a gap in the software industry, around open source software. There are a lot of developers in the industry, from students to experienced developers that are interested to get involved in something in addition to their day time position, but aren't really sure where to start. There are also a great deal of interesting projects covering everything from popular open source frameworks to the Adopt a JSR program launched by the LJC. Many of these projects rely on support/enthusiasm from developers and are keen to get more enthusiastic people involved. Not to mention that most candidates that get involved in personal projects seem to escalate their careers, salaries, day rates and passion for the industry (which all makes our job easier ;-)). Having been involved in several sporadic events over the last few years that aim to plug this gap, we started a series of events called LJC Meet a Project (#LJCMaP). They are run in a speed networking style, similar to the GDC Meet a Mentor events, they involve Project Ambassadors speaking to small groups of 3-6 developers. Giving a pitch of the project, then answering questions before moving on to another group. The events are intended to answer potential committers' questions around the projects, focussed mainly around starting points. These are not recruitment events or opportunities for companies to find new employees, but to help offer a way for developers to work alongside their existing positions to gain experience and develop communications and technical skills. The events are organised by RecWorks, the events team here will take care of all of the organisation/facilitation of the events to ensure that all is well organised and the process is as smooth as possible, so all you need to do is turn up on the day.

Re: [rules-users] Guvnor 6.0.0.Final: Unable to connect to guvnor repository using JBoss Dev Studio
Are you using the Drools 6.0.0 Eclipse plugin? Drools Workbench 6.0 (old Guvnor) doesn't support WEBDAV since it now uses a GIT backend (and not JCR). You can clone the repository from within Eclipse and access it using normal GIT functions.

Re: [rules-users] Guvnor 6.0.0.Final: How to assign package and category permissions?
Drools Workbench 6.0 doesn't support the same granularity of permissions as Guvnor 5.5. Drools Workbench supports user permissions at the Organizational Unit, Repository and Project level: users either have access, or do not. You can use the kie-cli-config tool to add required roles to the foregoing logical entities; and assign roles to users using whatever mechanism suits your runtime container. For example, if you're using the AS7 distribution you can assign roles to users with adduser.sh within AS7's /bin folder. We will add the ability to assign roles to Organizational Units, Repositories and Projects through the UI in a future release. In Guvnor 5.5 the deployment unit was a proprietary PKG file generated from individual packages. Drools Workbench 6.0 uses JAR (which equates to a project) as the deployment unit. If you wish to restrict access to different packages you should split your rules etc into different projects; setting up dependencies between them as you require.

Re: [rules-users] Guvnor 6.0.0.Final: What is the deployment flow?
Hello, In Drools 6.0 the deployment unit is a JAR. It is built when you Build and Deploy the project (from the Project Editor). Drools Workbench deploys the JAR to the workbench's Maven repository; that can be added to your projects pom.xml as an additional repository and the JAR added as a dependency. The Repository URL will be of the format: http://hostname:port/webcontext/maven2/ where hostname, port and webcontext reflect your deployment configuration. There have been other emails to this mailing list asking similar questions over the last couple of days. Please read those too, as they embellish on this answer.

[rules-users] Optaplanner ShiftAssignment Employee is null
Hi,
I have a strange error. When I get my final roster, I do:
System.out.println(final_roster.getShiftAssignmentList());
I get a list of all the employees (with their names) assigned to a certain
shift on a certain date.
Now I would like to iterate over this list to save it to my database, so I
do the following to test:
for (ShiftAssignment shiftAssignment : roster.getShiftAssignmentList())
{
System.out.println(Shift assignment: + shiftAssignment.getEmployee()
+ - + shiftAssignment.getShiftDate() + - +
shiftAssignment.getShift().getLabel());
}
But now the shiftAssignment.getEmployee() returns null. How can this happen?
Thanks

Unfortunately it appears we don't actually have a download for kie-cli-config; so regrettably you'll need to build from sourcehttps://github.com/droolsjbpm/kie-wb-distributions/tree/master/kie-config-cli .
