Someone earlier here mentioned that you could put the settings in a
file outside the application, but that is not possible in this case,
or is it ?
You can have web.xml parameter, e.g.
<context-param>
<param-name>config-file-location</param-name>
<param-value>/filesystem/path or URL or
some-other-location</param-value>
</context-param>
And then you can retrieve parameter value, thus, read config file.
Idea is, that param-value is the same for every client/build. E.g.
points to configuration file in $CATALINA_HOME/conf. So you can have one
war file and client dependant configurations.
Ok, that would work if you wrote the webapp yourself, and all the
filters that go with it. It would however not work if there are some
customer-specific parameters in web.xml, that are outside of your
control. (I'm thinking for example of a UrlRewrite or jCIFS filter)
Would there be a way to create a war file that does not contain a
WEB-INF/web.xml file, but maybe contains a "soft link" to a whole
web.xml file located somewhere else ?
The basic idea is : I could still give my customer a war-file that he
can deploy containing my updated classes of jars or whatever, but it
would not overwrite his customer-specific web.xml when he deploys it.
I think this issue is so general/generic that there must exist some way,
no ?
