This question is "cousin" of this one involving Android. But here we are in Tomcat environment.
If in my webapp I set a property with System.setProperty("property_name", "property_value");, which scope will it be applied to?
Many thanks!
A system property has a JVM scope. The property will thus be modified (and available) in the whole tomcat JVM, for all the webapps and for Tomcat itself.
Note that the system property is stored in memory, and will thus not persist if you stop and restart Tomcat.
