Hi, I've just checked out and successfully compiled: https://github.com/droolsjbpm/guvnor/tree/5.5.x I've tried to deploy this in jboss-as-7.1.1.Final but got the following error: 16:48:14,132 ERROR [org.apache.catalina.core.StandardContext] (MSC service thread 1-4) Context [/guvnor-webapp-drools-5.5.1-SNAPSHOT] startup failed due to previous errors: java.lang.IllegalArgumentException: Duplicate context initialization parameter resteasy.injector.factory at org.apache.catalina.core.StandardContext.addParameter(StandardContext.java:2186) [jbossweb-7.0.13.Final.jar:] at org.jboss.as.web.deployment.JBossContextConfig.processWebMetaData(JBossContextConfig.java:261) [jboss-as-web-7.1.1.Final.jar:7.1.1.Final] at org.jboss.as.web.deployment.JBossContextConfig.applicationWebConfig(JBossContextConfig.java:169) [jboss-as-web-7.1.1.Final.jar:7.1.1.Final] at org.apache.catalina.startup.ContextConfig.start(ContextConfig.java:417) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.startup.ContextConfig.lifecycleEvent(ContextConfig.java:182) [jbossweb-7.0.13.Final.jar:] at org.jboss.as.web.deployment.JBossContextConfig.lifecycleEvent(JBossContextConfig.java:162) [jboss-as-web-7.1.1.Final.jar:7.1.1.Final] at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:115) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.core.StandardContext.start(StandardContext.java:3790) [jbossweb-7.0.13.Final.jar:] at org.jboss.as.web.deployment.WebDeploymentService.start(WebDeploymentService.java:90) [jboss-as-web-7.1.1.Final.jar:7.1.1.Final] at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1811) at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1746) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) [rt.jar:1.7.0_13] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) [rt.jar:1.7.0_13] at java.lang.Thread.run(Thread.java:722) [rt.jar:1.7.0_13] 16:48:14,142 ERROR [org.apache.catalina.core.StandardContext] (MSC service thread 1-4) Context [/guvnor-webapp-drools-5.5.1-SNAPSHOT] startup failed due to previous errors 16:48:14,149 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-4) MSC00001: Failed to start service jboss.web.deployment.default-host."/guvnor-webapp-drools-5.5.1-SNAPSHOT": org.jboss.msc.service.StartException in service jboss.web.deployment.default-host."/guvnor-webapp-drools-5.5.1-SNAPSHOT": JBAS018040: Failed to start context at org.jboss.as.web.deployment.WebDeploymentService.start(WebDeploymentService.java:95) at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1811) [jboss-msc-1.0.2.GA.jar:1.0.2.GA] at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1746) [jboss-msc-1.0.2.GA.jar:1.0.2.GA] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) [rt.jar:1.7.0_13] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) [rt.jar:1.7.0_13] at java.lang.Thread.run(Thread.java:722) [rt.jar:1.7.0_13] 16:48:14,157 INFO [org.jboss.as] (MSC service thread 1-4) JBAS015951: Admin console listening on http://127.0.0.1:9990 16:48:14,158 ERROR [org.jboss.as] (MSC service thread 1-4) JBAS015875: JBoss AS 7.1.1.Final "Brontes" started (with errors) in 13913ms - Started 295 of 374 services (2 services failed or missing dependencies, 76 services are passive or on-demand) 16:48:14,358 INFO [org.jboss.as.server] (DeploymentScanner-threads - 2) JBAS015870: Deploy of deployment "guvnor-webapp-drools-5.5.1-SNAPSHOT.war" was rolled back with failure message {"JBAS014671: Failed services" => {"jboss.web.deployment.default-host.\"/guvnor-webapp-drools-5.5.1-SNAPSHOT\"" => "org.jboss.msc.service.StartException in service jboss.web.deployment.default-host.\"/guvnor-webapp-drools-5.5.1-SNAPSHOT\": JBAS018040: Failed to start context"}} 16:48:14,384 INFO [org.jboss.weld.deployer] (MSC service thread 1-3) JBAS016009: Stopping weld service for deployment guvnor-webapp-drools-5.5.1-SNAPSHOT.war 16:48:17,110 INFO [org.jboss.as.server.deployment] (MSC service thread 1-1) JBAS015877: Stopped deployment guvnor-webapp-drools-5.5.1-SNAPSHOT.war in 2745ms 16:48:17,111 INFO [org.jboss.as.controller] (DeploymentScanner-threads - 2) JBAS014774: Service status report JBAS014777: Services which failed to start: service jboss.web.deployment.default-host."/guvnor-webapp-drools-5.5.1-SNAPSHOT": org.jboss.msc.service.StartException in service jboss.web.deployment.default-host."/guvnor-webapp-drools-5.5.1-SNAPSHOT": JBAS018040: Failed to start context 16:48:17,113 ERROR [org.jboss.as.server.deployment.scanner] (DeploymentScanner-threads - 1) {"JBAS014653: Composite operation failed and was rolled back.
