Using the console I was unable to make it work.
After making your suggested changes:
- Replace @Resource with simplified path
* this seems to work in the other servers too
- Hard-code env-entry-value in web.xml
The application now deploys.
Digging down I was able to progress one step further:
bin/asadmin set-web-env-entry ...
allows changing the environment entries, but:
1. A hard-coded value in web.xml must be present for this to work
2. I could not find a place in the web console to perform this task.
