I deployed the Tomcat Guvnor war (guvnor-5.5.0.Final-tomcat-6.0.war) and renamed it to "guvnor". When I start the application I receive the following error report: java.lang.NullPointerException org.jboss.seam.transaction.TransactionServletListener.requestInitialized(TransactionServletListener.java:106) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:99) org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:936) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:407) org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1004) org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:589) org.apache.tomcat.util.net.AprEndpoint$SocketProcessor.run(AprEndpoint.java:1822) java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) java.lang.Thread.run(Thread.java:722) Can anybody help? I have to admit that this is my first attempt to use Guvnor Thank you in advance. Olaf -- View this message in context: http://drools.46999.n3.nabble.com/Delpoying-Guvnor-5-5-0-on-Tomcat-7-0-34...
