Re: [rules-users] unable to resolve method using strict-mode

It's compiled and working on Windows without any casting :) Check out the test project I attached. You will see that the rule will compile from web application (Windows only) or with Java SE application. The web application using JSF so in case to run it use application server with included JSF library. http://download.java.net/glassfish/v3/promoted/ Date: Fri, 2 Oct 2009 19:48:17 +0200 From: wolfgang.laun(a)gmail.com To: rules-users(a)lists.jboss.org Subject: Re: [rules-users] unable to resolve method using strict-mode Map() in the .drl file is bound to be interpreted as Map<Object,Object> so that a Map.get() returns an Object. To be able to call method getSomeMethod() you'd have to cast this result, according to ((SomeClass)$map.get("x")).getSomeMethod() I fail to understand how this could ever be avoided - strict or no strict, MVEL or not MVEL. -W 2009/10/2 Vladimir Perlov <vladperl(a)hotmail.com&gt; Hi Wolfgang, Thank you very much for quick response! I tried your suggestion and still getting the following error: Unable to build expression for 'consequence': Failed to compile: 1 compilation error(s): - (1,29) unable to resolve method using strict-mode: java.lang.Object.getSomeMethod() ' System.out.println($map.get("x").getSomeMethod()); ' : [Rule name='TEST'] At least now I have only 1 compilation error comparing to the previous variant. modified rule: rule "TEST" dialect "mvel" when $map : Map() then System.out.println($map.get("x").getSomeMethod()); end I believe that problem is related to strict-mode that somehow enforced on Linux but not on Windows. I tried to remove the strict mode using the the following approach but it seems don't have any effect. We have web application with many drools rules and it's working on Windows but when we deployed the same application to Linux we are getting failed compile errors ;) KnowledgeBuilderConfiguration config = KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration(); config.setProperty("drools.dialect.mvel.strict", "false"); kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(config); Please advise me. By the way I'm using drools 5.0.1 Date: Fri, 2 Oct 2009 18:30:25 +0200 From: wolfgang.laun(a)gmail.com To: rules-users(a)lists.jboss.org Subject: Re: [rules-users] unable to resolve method using strict-mode 2009/10/2 Vladimir Perlov <vladperl(a)hotmail.com&gt; Here is the rule that failed to compile on Linux: rule "TEST" dialect "mvel" Send when map : Map() $map : Map() or omit '$' in the consequence. -W then System.out.println($map.get("x").getSomeMethod()); end Lauren found her dream laptop.
