[rules-users] Performance gain by upgrading Drools Expert from 5.1 to 5.3

We recently upgrade our Drools Expert from 5.1 to 5.3, expecting big performance gain. But from the tests we done so far, the result is mixed at best. Is this common or there is sth we can fine-tune the system? http://drools.46999.n3.nabble.com/file/n3846747/PerformanceResult.png All time is in

[rules-users] load precompiled rule/ruleflow file in 5.3.0

We are upgrading from Drools 5.1 to 5.3.0.Final, and running into issues with loading precompiled rule/ruleflow files. Previously, we precompiled our drl files using ant task "org.drools.contrib.DroolsCompilerAntTask", e.g. rule1.drl to rule1.drl.rules. We did the similar thing for ruleflow files,

Re: [rules-users] how to invoke java method with variable arguments from drl file

Thanks for your reply. We do use "mvel". I found out that we have to change our signature in JAVA from methodA(String...) to methodA(String[]) and call it in rule like this: bjA.methodA(new String[]{"string1"}); then it worked. -- View this message in context: http://drools.46999.n3.nabble.c

Re: [rules-users] MVEL Expression causing NPE in MVEL optimizer

[rules-users] MVEL strict-mode vs. performance

Hi, We are upgrading from Drools 5.1 to 5.3 to improve the performance, but we are hoping to keep our drl files intact. We were trying to use the old drl files by setting "drools.dialect.mvel.strict=false", but somehow with this setting we still got " unable to resolve method using strict-mode .."

Re: [rules-users] MVEL Expression causing NPE in MVEL optimizer

The global (?) addressManager is initialized *before* inserting the fact. As for findFirstAddressByTypeByPerson(), the exception is thrown before it's invoked: the NPE is thrown as part of the MVEL optimizers. -- View this message in context: http://drools.46999.n3.nabble.com/MVEL-Expression-cau

We are upgrading from 5.1 to 5.3 and we had some rule flow files with .rf extension, but the new jBPM in 5.2 and after is creating bpmn files instead for process. Can we still use the old rf file? or we have to recreate them as bpmn file? Thanks. -- View this message in context: http://drools
