Hi again,
thank you all for your kind advice!
My responses follow:
@Josh: This "lazy" approach didn't work for me anyhow. I got just the same
NPEs. This really is kind of non-deterministic as it sometimes would work and
sometimes it wouldn't. I mean the whole
access-the-servlet-context-while-startup-thing.
@Mark: Yes, I know the possibility to give symbol values through web.xml but it
just doesn't feel right to mess with development configuration at such an
important and central place.
@Mihail: I was not able to exactly replicate what you were proposing. But
assume you just read resources from the class path?
In the end the last thing is what I am doing. I moved away from storing my
configuration in the servlet context and just treated my configuration file as
a plain java resource (that is, I moved it to the src/main/resources folder
instead of WEB-INF). Then, the solution is quite short:
public static void contributeSymbolSource(
final OrderedConfiguration<SymbolProvider>
configuration) {
configuration.add("DevSymbols", new
ClasspathResourceSymbolProvider("configuration.properties"),
"before:ApplicationDefaults");
}
Works like a charm for me.
Thank you again and best regards,
Erik
