Romain Manni-Bucau commented on TOMEE-1445:
-------------------------------------------
You can't deploy twice the same app in the same server instance by spec. But if
you change its name (module-name in web.xml/ejb-jar IIRC) then it will work.
until 1.5 - maybe 1.6 but I don't recall) - default module name was host/webapp
but we changed it to be fully spec compliant to webapp only. Specifying module
name you'll get it back - but it means you need to copy twice the war in
webapps/host1 and webapps/host2 after having configure host appBases to
webapps/host1 and webapps/host2.

> The issue is that I can't get my website to launch in Prd anymore. It's
> looks like TomEE is attempting to launch the same web app twice and then
> running into the duplicate EJB id issue. I notice in catalina.out that the
> app is started for localhost and then my domain name.
> I can't get rid of either Host definition either. Without either, I need to
> type in my site's domain name WITH TomEE's port number to access the web app.
> That scenario will not suffice.
> I don't recall having this issue in TomEE 1.6.0.1 or 1.6.0.2.
