1. Yes, env-entry-value is not filled.
These are configuration parameters, and I do not know what values
they will be assigned at deployment time. Hence the env-entry-value is
missing, and I *expect* them to be filled on deployment using whatever
means the server has. Manually *fixing* the web.xml descriptor in an
already packaged (and possibly cryptographically signed) WAR file is
not my idea of server deployment tools.
2. Do I *need* to omit the java:comp/env, or I *can* omit the prefix?
With other J2EE servers I was only able to get it running using the
full java:comp/env/config/user location.
I find it hard to believe, that deploying and configuring an
application would require:
a) Hard-coding values by the developer.
b) Manually editing packaged files by hand.
Am I missing something? Am I supposed to recompile/repackage the WAR
for every instance? Because I can't find a way for this to work
otherwise. I thought I am to provide a WAR file with declared
references to configuration parameters, that are configured/linked
when deploying to the server.
After hard-coding some values for the configuration attributes in
web.xml and attempting to deploy the application I got:
> An error has occurred
> Error occurred during deployment: null. Please see server.log for more details.
And the server.log has:
> [2014-07-22T12:28:03.320+0300] [glassfish 4.0] [INFO] [] [org.glassfish.admingui] [tid: _ThreadID=122 _ThreadName=admin-listener(9)] [timeMillis: 1406021283320] [levelValue: 800] [[
> Exception Occurred :Error occurred during deployment: null. Please see server.log for more details.]]
Which is unhelpful to say the least. I suspect a NPE occurs
somewhere on the server, but the exception is
masked/wrapped/ignored/printed and the actual cause eludes me.
The same thing happens if I try to deploy the application without
starting it: I get an error message 'null', and then trying to deploy
the application again yields:
> An error has occurred
> Error occurred during deployment: Application name DemoApplication is already in use. Please pick a different name.. Please see server.log for more details.
