[rules-users] pattern / tag is not working in rule file
Hello all I am using Drools 4.0.3 I am using a .xml rule file in my application in which I am validating the user entered data through my rule file. When I am not using pattern / tag in my rule file then it is working fine but when I use it ,the rules are not firing even it is not showing any exception also. For your reference I am coping my rule file below : ?xml version=1.0 encoding=UTF-8 ? package xmlns=http://drools.org/drools-4.0; xmlns:xs=http://www.w3.org/2001/XMLSchema-instance; name=jbossrules xs:schemaLocation=http://drools.org/drools-4.0 drools-4.0.xsd import name=com.wipro.evalidator.response.bean.ResponseBean / global identifier=response type=com.wipro.evalidator.response.bean.ResponseBean / import name=java.lang.* / import name=com.wipro.airline.SearchBean / rule name=rule1 rule-attribute name=agenda-group value=AirlineApp / rule-attribute name=activation-group value=activation_1195126928297 / lhs pattern identifier=searchbean object-type=com.wipro.airline.SearchBean / evaltrue/eval /lhs rhs System.out.println(date is not valid.);response.setStatus(failure);response.setSubStatus(date_notva lid); /rhs /rule /package If pattern / tag is not allowed here then how can we use SearchBean fields in the lhs part of the rule.

Re: [rules-users] Problem with ternary and mvel
Thanks for the answer. I can move on now. And I'm going to use your function solution. V. Mark Proctor wrote: vdelbart wrote: I try in 4.0.4 it doesn't work. Nobody have an idea ? We do not currently allow any imperative code for MVEL, it is disabled. This is on purpose to enfore declarative rules - call a function to apply your imperative code.

[rules-users] Multiple DSL sources
Hi everybody, I was wondering whether is possible to add multiple DSL sources to a single rule package. If we look to the *PackageBuilder* methods we do not find any method which allows us to add more than one DSL source per DRL reader. I would like to be able to do something like: *package myRulePackage* *expander DSLsource1;* *expander DSLsource2;* ** *rule myMultipleDSLRule* *when* *#* *then* *#* *end* ** ** *.* ** *rule* *.* *end* Is That possible?? In case It weren't possible, Would It be any workaround to this? I guess I could workaround this using the class *DefaultExpanderResolver* but I have got no idea on the way to do it. Can You suggest me any way to do it? Does anybody have ever had the same issue? Let me know. Thank You anyway.

Re: [rules-users] Multiple DSL sources
Hmm... if you look in BRMSPackageBuilder in the BRMS source code, you can see you can add DSL files together (you just have one expander statement - the expander statement is for the IDE) - however, I think that may not work in eclipse to make it content assistance pick up the other DSL file.

Re: [rules-users] OutOfMemory with BRMS 4.0.3
Hi Michael, I'm not at my company these days so I cannot check or make further tests. But yes, we use a rule agent and an URL to query the rule. And it happens after 1-2 days whether we use the system or not, it doesn't seem to make any difference. however, I'll check when returning, but I think it still worked after a few days, now that I have moved the BRMS to the Jboss 3.2.3 app server. thanks for trying to help me!

Re: [rules-users] OutOfMemory with BRMS 4.0.3
Thanks sophie. Any oome I will investigate it just takes time to find them. I have been running some overnight tests myself today. When you get back to work if you could provide more info it would be great. If the agent is running then it polls the brms. So that could be one of the possible causes.

[rules-users] BRMS Insurance Sample - InvalidClassException
Folks, I'm working through the BRMS insurance example (the very last section in the Drools documentation). I can build ( the example) and deploy both it and the BRMS ok. I import the repository , rebuild the snapshot binaries (BRMS), then hit the 'Continue' button on the drools insurance I get the InvalidClassException (below). I remember testing this for Edson and Ferando a couple of months back, so it could be something stupid that I'm doing. I'm running JBoss 4.2.1 , Java 1.6.0_03 on Windows Vista. I'm currently using BRMS 4.0.4 , with the insurance example from the Trunk (4.1.0 Snapshot), Other things I've tried: 1) All combinations of latest stable 4.0.4 and Trunk (including the obvious 4.0.4 for both, and the snapshot for both) 2) I've extracted the fact classes from the insurance war, made a standalone jar, and imported these into the BRMS 3) I've check the URL that the Insurance example uses, and modified it to take ' /LATEST'. Michael (thanks for the earlier suggestion) : Is this (number 2) what you meant by updating the Jars? Any other suggestions that I can try?
