Re: [rules-users] Slf4j Log4j logger not working with Drools drl while using as a global variable.
I wonder if OP Soumya solved the issue, because at least in my case it is indeed working fine - I just tested with 610Final as we also wanted to log from rule via slf4j. I attach demo that at least for us proves working. I've also tried back-port the same project attached to test with 610beta2, and is working as well at least for me; although you need to be aware switch the 'packaging' to see the log in eclipse (ref. https://issues.jboss.org/browse/DROOLS-495) Am I missing something? OP Soumya did you solved your issue? 20140805.zip http://drools.46999.n3.nabble.com/file/n4030572/20140805.zip Thanks.

Re: [rules-users] Slf4j Log4j logger not working with Drools drl while using as a global variable.
Check if the logger isn't null (by adding a System.out in the then part of the rule). If that's the case, then that error message is pretty poor (or even incorrect): java.lang.RuntimeException: cannot invoke method: info It should clearly talk about a NullPointer instead. So, if that's the case, create a jira issue. https://issues.jboss.org/browse/DROOLS On 27-05-14 07:09, Soumya.plavaga wrote: I am using global slf4j log4j logger as a global variable within our drl and inserting that global logger value at runtime into kiesession.

Re: [rules-users] Slf4j Log4j logger not working with Drools drl while using as a global variable.
@Geoffrey: did you see the java.lang.ArrayIndexOutOfBoundsException? Doesn't look like a null pointer causing an exception. The upstairs exception might add the basic exceptions's message to its message. @Soumya: Which Drools version are you using? Basically, this situation is handled correctly by 5.4 and 5.5. -W On 27/05/2014, Geoffrey De Smet ge0ffrey.s...@gmail.com wrote: Check if the logger isn't null (by adding a System.out in the then part of the rule).
