[rules-users] NoClassDefFoundError while invoking a consequence

[Vikrant Yagnick]

Hi All,

I am getting a rather strange error. When, I am invoking certain rules I get the following error as shown below(NoClassDefFoundError). I am using a stand-alone client (not an application server). The rulebase I am using is loaded in memory, so can't see why I should be getting this error.

When I print  the rules available in the RuleBase it correctly lists all the rules, yet I get the error below.

I am using Drools 4.0.7 and merging different files into the same package. If I do not merge the files, it works.
Anyone have any idea what this is? Is it somehow related to the following:- https://jira.jboss.org/jira/browse/JBRULES-1684.

Cheers,
Vikrant
