[jboss-user] [Beginners Corner] - DeploymentException: Web mapping already exists for deployme
I am brand new to JBoss and am evaluating version 5.0.0 for a new development environment
that is urgently needed.
I have started with the simple example documented below and deployed the resulting war
file to
"C:/MyStuff/jboss-5.0.0/server/default/deploy/hello.war".
Upon starting JBoss, I get the following exception:
org.jboss.deployers.spi.DeploymentException: Web mapping already exists for deployment URL
file:/C:/MyStuff/jboss-5.0.0.
GA/server/default/tmp/deploy/hello56098-exp.war/
I'll get an "HTTP Status 404 error . . . The requested resource (/hello.jsp) is
not available" when trying to access the URL: http://localhost:8080/hello.jsp.
Any help is most appreciated,
Greg
