Ok. For hello2, I should have accessed it with '.../hello2/greeting'. That works.
For hello1, I undeployed and redeployed it. Both took effect without having to restart.
Removing a http listener (on port 80) from 'server' takes effect right away. However, adding the http listener back to 'server' would not take effect until after restart. Is this an expected behavior or a bug?
