[rules-users] Drools flow and BPEL (Drools 5.1)

Hello, I am studying how to integrate Drools 5.1 into our product. And we will need a BPEL engine embedded in Drools. I read from the "Drools Flow User Guide" that "the Drools Flow engine is based on a generic process engine that allows the definition and execution of different types of process la

The thing is that, afaik, the DrlParser in itself doesn't give you something that you can use to generate the BRL XML, even for a well-behaved DRL.

Thank you, Edson. I've thought about it. There are some inconsistencies in the application integrating my application. Therefore using sliding windows is kind of problematic. There for I'm using the events timestamps as a compromise ... I know, its very critizisable, but I can't change it. Th

For a pair of events, the performance will be the same with before/after. If you have more than 2, though, best would be to use sliding windows. Edson 2010/9/14 Tina Vießmann : > Hi, > > I've mentioned the test case I'm working on before. It's: If a certain value > exceeds a limit more than

[rules-users] Guvnor war 5.1

We are currently using drools guvnor 5.0.1 deplyed in Weblogic 10.3. We needed to multithread the call to the rule engine. We were facing the issue of Concurrent modification as described in https://jira.jboss.org/browse/JBRULES-1888. It seemed to have been fixed and we tried upgrading it to 5.1.

[rules-users] How to remove a persisted session from the database ?

Hi, I am using persistence, and since the sessions don't seem to have a standard way of getting removed from the database when they are not needed anymore, I am wondering how to do that. I am using JPA but if I call : em.remove(someSessionInfo); where em is the JPA EntityManager, that does not r

This is good to know. I was just in the middle of converting to 5.1.1 but will not stop. By the way the 5.1.1 version of Guvnor appears to be unstable under JBoss 5.1. Verify operations just hang. Error messages (with no message) get displayed, Inability to sign out, etc. Back to 5.0.1. O

Re: [rules-users] [rules-dev] Technical Rules

You are right, of course. The BRL editor has its own XML format. I just wonder whether going through a DrlParser - DrlDumper cycle might produce a sufficiently "well-behaved" DRL text that could be easily enough transformed to the BRL XML. But nothing of this is in the "stable" API, so it would b

I might be wrong, but I think DRL -> BRL is still not possible. Just had a look at org.drools.ide.common.server.util.BRDRLPersistence, and we have the following: public RuleModel unmarshal(String str) { > throw new UnsupportedOperationException( > "Still not possible
