I need to create an application packaged as a .war file that updates a database and supports transactions. I also need to deploy this application in JBoss but in the Tomcat Only configuration. I created a test application, deployed it in the "default" installation of JBoss (along with a test-ds.xml file identifying the location of the database) and everything worked as expected. I then installed JBoss taking the Tomcat only option, deployed the application and test-ds.xml file and things would not deploy. Specifically, the errors on the console revealed it could not deploy the test-ds.xml file: deployer unknown. Does anyone know how to do this? Is there any documentation I can read? Is there a "deployer" I need to activate or turn on (without adding a lot of overhead)? Thanks! Kelly View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4081074#...
