I'm trying to deploy my seam app on Tomcat (with embedded JBoss) without much luck. I'm getting the following exception but it doesn't make much sense to me. I've read and followed all the steps in http://docs.jboss.com/seam/2.0.0.B1/reference/en/html/configuration.html#... and [url]http://wiki.jboss.org/wiki/Wiki.jsp?page=EmbeddedAndTomcat, including adding the embedded JBoss listener (last) in server.xml and the WEB-INF scanner listener in context.xml. I WAS able to run ant deploy.tomcat on the Seam booking example and it works just fine. I then tried modeling my app config files after the booking ones but I'm still getting the exception below. Any help/clues are appreciated. <UNKNOWN> -> ** UNRESOLVED AbstractDemandMetaData$DemandDependencyItem@1aee513{n | ame=persistence.units:unitName=mmogwidgets dependsOn=null whenRequired=Described | resolved=false demand=jboss.jca:name=mmogwidgetsDatasource,service=DataSourceBi | nding} ** | | | at org.jboss.embedded.DeploymentGroup.checkIncomplete(DeploymentGroup.ja | va:151) | at org.jboss.embedded.DeploymentGroup.process(DeploymentGroup.java:129) | at org.jboss.embedded.tomcat.WebinfScanner.lifecycleEvent(WebinfScanner. | java:88) | ... 24 more View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4061417#...
