Hello Brian, I tried the same example in Spring, using the spring modules https://springmodules.dev.java.net/ JSR 94. It works fine...

Within DroolsTest.java: Boolean performCheck = new Boolean("true"); statefulSession.setGlobal("performCheck", performCheck); Within the rule file: global java.lang.Boolean performCheck; rule "Display if true" when eval(performCheck) then System.out.println(performCheck); end When I run DroolsTest I get the output of 'true', the value of performCheck, as I would expect. When I use the same rule in my Spring environment the rule fails to execute. I know the gloabl is getting to the rule with a value of "true" as I have a second rule which always fires and reports the value of performCheck. Has anyone ever experienced this and if so did you find any solution? Thanks in advance, Brian Enderle
