This definitely isn't a good option as I don't intend to make a difference
by the way in which I reference a variable.
Anyway, property-placeholder doesn't seem to me to be a good option as some
of the variables inside my cfg file are seen, some aren't. For example I
get this:
Error creating bean with name 'ftpClientFactory' defined in URL
[bundle://afa89085-51c4-4cb3-a419-afeccd70a35f_304.0:0/OSGI-INF/blueprint/spring-conf/spring-context.xml]:
Initialization of bean failed; nested exception is
org.springframework.beans.TypeMismatchException: Failed to convert property
value of type 'java.lang.String' to required type 'int' for property
'reconnectRetries'; nested exception is java.lang.NumberFormatException:
For input string: "{{reconnect.retries}}"
In the same spring context, another variable (which is present in the same
configuration file) is well referenced.
Thanks,
Andrei M.
