How can I create a war or ear file from class of java and deploy it to JBOSS 5.1.0.GA

New to IntelliJ, I am wondering, How can I create a war or ear file from class of java and deploy it to JBOSS. I have created the jar file using JAR command and getting message

C:\jboss-5.1.0.GA\bin\run.bat -c default
