My original intent was to use only Messaging. So I did the following to create a "standalone-messaging" server. 1) Extracted jboss-4.0.4.GA.zip to C:\java folder 2) Extracted jboss-messaging-1.0.1.GA.zip C:\java folder. 3) Extracted apache-ant-1.6.5-bin.zip to C:\java 4) Opened a command prompt and did the following: cd C:\java\jboss-messaging-1.0.1.GA\util set JBOSS_HOME=C:\java\jboss-4.0.4.GA C:\java\apache-ant-1.6.5\bin\ant -f release-admin.xml standalone Now, when I tried to deploy an EAR to "standalone-messaging" server (I did not remove any files), I received the following exception: 2007-01-30 11:03:56,697 DEBUG [org.jboss.deployment.MainDeployer] No deployer found for url: file:/C:/java/jboss-4.0.4.GA/server/standalone-messaging/deploy/Test.ear 2007-01-30 11:03:56,697 DEBUG [org.jboss.deployment.MainDeployer] deployment waiting for deployer: file:/C:/java/jboss-4.0.4.GA/server/standalone-messaging/deploy/Test.ear 2007-01-30 11:03:56,697 DEBUG [org.jboss.deployment.MainDeployer] Watching new file: file:/C:/java/jboss-4.0.4.GA/server/standalone-messaging/deploy/Test.ear 2007-01-30 11:03:56,697 DEBUG [org.jboss.deployment.MainDeployer] Deployment of package: file:/C:/java/jboss-4.0.4.GA/server/standalone-messaging/deploy/Test.ear is waiting for an appropriate deployer. 2007-01-30 11:03:56,697 DEBUG [org.jboss.deployment.scanner.URLDeploymentScanner] Watch URL for: file:/C:/java/jboss-4.0.4.GA/server/standalone-messaging/deploy/Test.ear -> file:/C:/java/jboss-4.0.4.GA/server/standalone-messaging/deploy/Test.ear 2007-01-30 11:03:56,697 ERROR [org.jboss.deployment.scanner.URLDeploymentScanner] Incomplete Deployment listing: --- Packages waiting for a deployer --- org.jboss.deployment.DeploymentInfo@c94153c9 { url=file:/C:/java/jboss-4.0.4.GA/server/standalone-messaging/deploy/Test.ear } deployer: null status: null state: INIT_WAITING_DEPLOYER watch: file:/C:/java/jboss-4.0.4.GA/server/standalone-messaging/deploy/Test.ear altDD: null lastDeployed: 1170173036697 lastModified: 1170173036697 mbeans: --- Incompletely deployed packages --- org.jboss.deployment.DeploymentInfo@c94153c9 { url=file:/C:/java/jboss-4.0.4.GA/server/standalone-messaging/deploy/Test.ear } deployer: null status: null state: INIT_WAITING_DEPLOYER watch: file:/C:/java/jboss-4.0.4.GA/server/standalone-messaging/deploy/Test.ear altDD: null lastDeployed: 1170173036697 lastModified: 1170173036697 mbeans: 2007-01-30 11:03:56,728 DEBUG [org.jboss.deployment.scanner.AbstractDeploymentScanner$ScannerThread] Notified that enabled: true 2007-01-30 11:03:56,728 DEBUG [org.jboss.deployment.scanner.URLDeploymentScanner] Started jboss.deployment:flavor=URL,type=DeploymentScanner 2007-01-30 11:03:56,728 DEBUG [org.jboss.system.ServiceController] Starting dependent components for: jboss.deployment:flavor=URL,type=DeploymentScanner dependent components: [] 2007-01-30 11:03:56,728 DEBUG [org.jboss.deployment.MainDeployer] End deployment start on package: jboss-service.xml 2007-01-30 11:03:56,728 DEBUG [org.jboss.deployment.MainDeployer] Deployed package: file:/C:/java/jboss-4.0.4.GA/server/standalone-messaging/conf/jboss-service.xml 2007-01-30 11:03:56,728 DEBUG [org.jboss.web.tomcat.tc5.Tomcat5] Saw org.jboss.system.server.started notification, starting connectors View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4008371#...
