Hi, Just wondering if anyone has any experience with the following scenario and if so, did you find a solution? 1. I deployed this Beta2 version successfully onto Tomcat. 2. Then during the launch the following error message popped up: - 400 Sorry, a technical error occurred. Please contact a system administrator. Thanks in advance... -- View this message in context: http://drools.46999.n3.nabble.com/Guvnor-5-4-0-Beta2-launch-Error-tp37623...
