Sendmail-ear.ear can be successfully deployed on geronimo 3.0 snapshot.
Open http://localhost:8080/sendmail/ in a web browser ,this application works fine.
But As far as I can remember if the ear contains a war package and this war package is specifiled in application .xml like:
Then on admin console,under Console Navigation/Applicatios,click web App Wars,it/s expected to see an item like this:
org.apache.geronimo.samples/sendmail-ear_sendmail-war-18.104.22.168.war/2.1.1/car /sendmail running Stop Restart Uninstall
then we can get access to the application via the link /sendmail.
But currently on 3.0 snapshot console,the deployed war will not be listed.
