Re: [rules-users] Multiple approvals in a Drools Workflow Doubt
Hi Kris , Thanks for your reply. As you have said that drools workflow supports persistence state of a workflow. So can you tell me how to get the current instance Id of the process. How state is persisted in Drools workflow? Is Drools flow uses some database to store the process instance Id to store the state of the process like in JBPM? Please help to answer my queries.

Re: [rules-users] Multiple approvals in a Drools Workflow Doubt
So can you tell me how to get the current instance Id of the process. ProcessInstance processInstance = ksession.startProcess(myProcess); long processInstanceId = processInstance.getId(); How state is persisted in Drools workflow? Is Drools flow uses some database to store the process instance Id to store the state of the process like in JBPM? Yes, the persistence is fully pluggable (meaning that you can run the engine without any database behind it), but we provide a JPA-based implementation for storing the state in any persistent store supported by JPA. For more info, check out the documentation: https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-flow/html/ch05.html#d0e1479 Thx, Kris Disclaimer: http://www.kuleuven.be/cwis/email_disclaimer.htm ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] How to change default Persistence Manager , Hibernate in Drools Flow to OFBiz entityengine persistence manager
Hi Users,I have a doubt regarding the persistance mechnanism in Drools Flow.By default drools flow supports Hibernate as persistence manager.Now I am integrating Drools Flow with OFBiz and OFBiz uses entityengine as a persistence manager. http://ofbiz.apache.org/docs/entity.htmlNow I have seen in the docs that persistence manager can be changed by changing thedefault setting in persistence.xmlSo can you please tell me what are the things I have to do to use my persistence manager and use Mysql database instead of file-based H2database.Also is this possible to use OFBiz pesistence manager here?Please help me to achieve this as it is very urgent.Thanks RegardsPardeep RuhilThis email may contain confidential or privileged information for the intended recipient(s).

[rules-users] Maps in Drools
Hi, I'm relatively new to both Java and Drools. I'm trying to figure out how to use maps in Drools. I've looked at the thread http://www.mail-archive.com/rules-users@lists.jboss.org/msg09802.html From what I've read generally it seems best to insert objects directly rather than use nested accessors. So I've been experimenting with trying to insert a map and then checking stuff in it. I set up a simple test map of String to Integer, with just a as key and 1 as value, and b with 2. MapString, Integer map = new HashMapString, Integer(); map.put(a, 1); map.put(b, 2); String a = a; I then inserted the map and also inserted the String a of value a. Here's the test rule, with various things I tried commented out: rule testing maps dialect mvel when $str: String() // $m: Map( this[$str] == 1 ) # error // $m: Map( this.$str == 1 ) # error // $m: Map( this[$str] == 1 ) # compiles but rule won't fire $m: Map( this[a] == 1 ) # this works however! then System.out.println($m[$str]); #also works with String and Map objects no conditions end It obviously doesn't like it when I try to use the String object as the key for the map. But it works when I use a String literal as the key. What am I doing wrong? Does anyone have any suggestions please, or shall I give up and either use eval as mentioned in http://www.mail-archive.com/rules-users@lists.jboss.org/msg09716.html or use the map as a field of another object which I insert instead of the map (in fact that was my original plan!)? I'd also need to test for null i.e. whether a key/value pair exists for a given String as the key. Any thoughts would be very much appreciated.

Yes, that was a bug that was fixed in newer versions of MVEL. Just update your MVEL jar to 2.0.12.

In exactly this thread Marc answered to that problem. http://www.mail-archive.com/rules-users@lists.jboss.org/msg09837.html His first idea is that this is a bug in the mvel dialect. I tried exactly that. I had a global var and put the string a into it. Then I wanted to check if Map( this[myVar] == 1 ) but this didn't work. I'd also need to test for null i.e. whether a key/value pair exists for a given String as the key. This seems to be only true when you go the route that I go, namely using the default rule syntax, i.e., eval. Sunny greetings, André -- Lisp is not dead.

[rules-users] Is emptieness supported in Drools 5 (LHS)
According to MVEL they've added a convenience for checking the emptiness of a value (see: http://mvel.codehaus.org/Value+Tests ) In MVEL you'd simply write: myMap == empty This seemed like a MUCH cleaner way to write some of the LHS of the rules, so I thought I'd try it out. Given the following rule: rule Check Empties - Original when $grabBag : MyGrabBag(someMap != null) eval ($grabBag.getSomeMap().size() == 0) then end This could be rewritten: rule Check Empties - Simple when MyGrabBag(someMap == empty) then end The IDE (Eclipse 3.4.2 w/ Drools plugin) seems to recognize empty is a keyword (it makes it bold), but the drools compiler in the IDE reports: BuildError: Unable to create restriction '[VariableRestriction: == empty ]' for field 'someMap' in the rule 'Check Empties - Simple' BuildError: Unable to return Declaration for identifier 'empty' Am I assuming incorrectly that the LHS is fully MVEL compliant? ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Maps in Drools
Many thanks for your replies André and Edson. For some reason they hadn't shown up on my computer before I posted my follow up info. I'll download the updated jar and cross my fingers! On the general issue, is it received wisdom that it's better not to insert map objects direct, at least for now until map support is fully there - or is it 6 of one / half a dozen? André on your point below: André Thieme-4 wrote: KDR schrieb: I'd also need to test for null i.e. whether a key/value pair exists for a given String as the key. This seems to be only true when you go the route that I go, namely using the default rule syntax, i.e., eval. - I don't think I quite follow? If I need to check whether the key/value pair exists for a particular String key i.e. whether the get(key) returns null, is the only way to do that currently by using the eval?
