Re: [rules-users] Building Guvnor from source
Personally, I have these set in Eclipse:- -XX:MaxPermSize=512m -Xms512m -Xmx2048m Lower values might work (I believe there is something about this in the droolsjbpm-build-bootstrap\README.md).

[rules-users] Object activiates same rule many times
Hi all, I find an odd pattern in the audit log. When an Object is inserted to the working memory, activation is created many times on same rule. The more objects are inserted, the duplicated activations are growing exponentially which degrade the performance a lot. Here attached part of the audit log: http://drools.46999.n3.nabble.com/file/n4000630/rule-DOCSEP-1337325521971.log rule-DOCSEP-1337325521971.log In the log, - when object (130) is inserted, rule C020 - Gate charge (Out M)-B is activiated 129 times. - when object (131) is inserted, rule C020 - Gate charge (Out M)-B is activiated 130 times. Here is the rule of C020 - Gate charge (Out M)-B, The insert in RHS only add ChargeDetailRefSeqEntity to working memory that I don't think it causes the recursive activation. And I'd already set no-loop to true. Does anyone offer some help here?

Please show the rule. Exponentially growing activations can be caused by rules where the same fact type is used more than once.

When using or, only one pattern of the or expression will be bound.
So, at runtime, onlty one variable $p1 or $p2 exists, and the other is null so
the NPE at runtime.
By the way, I can't see you are using a or here, as you test exactly the same
things ...

[rules-users] [5.4.0] Combining custom operators with OR results in compile error
Hello List,
I recently migrated from Drools.5.0.1 to Drools.5.4.0 and I am having issues
when combining constraints with OR when custom operators are involved.
For example, the following rule:
rule r548695.1
no-loop true
dialect mvel
when
gnId : GN()
la : t547147( )
v1717 : Tra48( gnId.gNo==gNo , name F_str[startsWith] la.c547148 || postCode
F_str[contains] la.c547149 )
then
System.out.println(Rule r548695.1 fired);
end
results in the following exception:
Unable to Analyse Expression gnId.gNo == gNo ( F_str0.evaluate( name,
la.c547148 ) || F_str1.evaluate( postCode, la.c547149 ) ):
[Error: unable to resolve method using strict-mode:
my.package.rulez.Tra48.F_str0()]
[Near : {... gNo == gNo ( F_str0.evaluate( name, la.c54 }]
^ : [Rule name='r548695.1']
Please note, that the same rule using AND () between the custom operators
compiles OK.
The above rule had not problem whatsoever in Drools.5.0.1.
Any ideas to overcome this issue, are most welcomed.

[rules-users] Classnotfound exception on POJO model upload in guvnor
Hello, I'm trying to use Guvnor but when i upload my POJO models that my DRL needs i get a classnotfoundexception even though i uploaded the jar that has the class in it first. So i basically upload a jar that provides some common classes,utilities, that have no dependencies other than on the core java libs. This jar uploads fine. I then upload my model jar that contains my facts and other classess that the DRL needs and it complains that it can't find the class from the first common jar even though i uploaded it first and it is loaded without errors. How do i load all of my jars so that they are available in Guvnor to use such as in creating a test scenario? It looks like the jars are upload but i get the error, i can also build the package but i'm worried it won't work when i try to use it in my app. Any ideas or insight to this issue.

Re: [rules-users] Classnotfound exception on POJO model upload in guvnor
I think (not sure) that an uploaded jar must be complete by itself. The only things (classes) it can reference must be in guvnor's classpath (guvnor own libs and tomcat and java, but not current package other jars). So : - try using a single jar - or put all your jars in guvnor classpath (tomcat libs or guvnor war's libs) PS : When using your app, the classpath will be your app's one. When you get rules from guvnor, you don't get jars with them ... so it is two different environments. - Mail original - De: mpgong michael.p.g...@lmco.com À: rules-users@lists.jboss.org Envoyé: Vendredi 18 Mai 2012 17:37:55 Objet: [rules-users] Classnotfound exception on POJO model upload in guvnor Hello, I'm trying to use Guvnor but when i upload my POJO models that my DRL needs i get a classnotfoundexception even though i uploaded the jar that has the class in it first. So i basically upload a jar that provides some common classes,utilities, that have no dependencies other than on the core java libs. This jar uploads fine. I then upload my model jar that contains my facts and other classess that the DRL needs and it complains that it can't find the class from the first common jar even though i uploaded it first and it is loaded without errors. How do i load all of my jars so that they are available in Guvnor to use such as in creating a test scenario? It looks like the jars are upload but i get the error, i can also build the package but i'm worried it won't work when i try to use it in my app. Any ideas or insight to this issue. I'm using drools.5.3.0 final.

Thanks, that makes sense. I was suspecting that would be the case. I'll give that a go. -- View this message in context: http://drools.46999.n3.nabble.com/Classnotfound-exception-on-POJO-model-upload-in-guvnor-tp4001060p4001282.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
