[rules-users] calling static error function....thread safe?

Hello, I am calling static "error" function in ValidationHelper class from drool rules. My rules are going to be executed in spring based web application. Is this call to an "error" function thread safe? public class ValidationHelper { public static void error (RuleContext kcontext, Object... context) { KnowledgeRuntime knowledgeRuntime = drools.getKnowledgeRuntime(); ValidationReport validationReport = (ValidationReport) knowledgeRuntime .getGlobal(ValidationConstants.VALIDATION_REPORT_GLOBAL); ReportFactory reportFactory = (ReportFactory) knowledgeRuntime .getGlobal(ValidationConstants.REPORT_FACTORY_GLOBAL); validationReport.addMessage(reportFactory.createMessage( Message.Type.ERROR, messageKey, context)); } } import org.drools.runtime.rule.RuleContext; import function ValidationHelper.error; ... rule test when #condition then error(drools) Please advise Thanks -- View this message in context: http://drools.46999.n3.nabble.com/calling-static-error-function-thread-sa...
