Hello, I am in charge to investigate new JBPM and Drools 6 status. I should say that I'm kind confuse. Looking at maven central, already have 6.0.0.Final artifacts: http://search.maven.org/#artifactdetails%7Corg.jbpm%7Cjbpm%7C6.0.0.Final%... But looking at http://www.jboss.org/jbpm/ there are any reference to 6.0.0 ! looking at jira here (https://issues.jboss.org/browse/JBPM) I could see the 6.0.0.Final was release, but there are 3 different versions:jBPM 6.1.0.Final, jBPM 6.0.1.Final and jBPM 6.x !!! could someone explain me that ? which version should I track in jira? which source branch is the one that I should clone if I need to see the examples? thanks, John. _______________________________________________ jbpm-dev mailing list jbpm-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/jbpm-dev

Binaries were released, but we're still working on communication (new web site, new tutorials, videos, etc...) But if you check http://www.jboss.org/jbpm Documentation or Downloads sections there are references to new release.

HI John, If you can highlight which issues that you see there are important to you please let us know. We are still cleaning Jira for the last release so some of them are already fixed or not relevant.

Hi Mauricio, I could see that many issues were resolved in Drools and JBPM Jira, that is really good. The system environment where we plan to use JBPM is Equinox. So, what concerned we most are the issues that wasn't raised yet related running 6.x into OSGi. In one entire day one of my team members wasn't able to make it run. I can't specify the problems right now because he got out for vacation without pass me the report file. But seems that it was related to classloading issues... I asked to someone to repeat his procedure this week again and we will raise the issues, if necessary... regards, John On 16/12/13 09:22, Mauricio Salatino wrote: > HI John, > If you can highlight which issues that you see there are important to > you please let us know.

Hello Cristiano, We have to agree with you. That factory approach is really a "point of risk" for osgi ! We had problems with hibernate too and we use Open JPA plus Aries JPA.

but you told me that there are people using drools with blueprint. but they wouldn't get into same problems too?

have you talked about this with the drools/jbpm teams ?

do you mind if I contact you personally ?
