[rules-users] What may go in the Action when dialect is java

Hi For some time I have been struggling to complete my Drools workflow without succes. I am trying to access static methods on som java classes but for some reason i keep getting NoSuchMethodException when switching the dialect from "mvel" to "java" to be able to call this methods. What I have at runtime is a message variable containing a campaign class instance which I want to parse on to my static method for it to return an campaign information class instance to me. Which I then set in a global variable that I read outside the knowledge session. The global variable is defined like this: global com.test.CampaignResult result The flow variable is defined like this: com.test.jpa.Message msg; My code lookes like this: Campaign c = msg.getCampaign(); CampaignInfo info = CampaignHelper.getCampaignInfo(c); result.setCampaignInfo(info); My Drools is 5.0.1 Can anybody help me on getting this to work?
