Adding reference to properties file in Tomcat context.xml or server.xml
I am trying to externalize a properties file outside of the app war in the tomcat context itself.This is so that the war can be build and ported to different env without having to change the properties file in each env every time.
Lets say that the properties file is called: app.properties
1) I placed all the properties, in tomcat_home/conf/context.xml and/or
tomcat_home/conf/Catalina/localhost/context.xml. Eg.,
<Context path=/app>
<Parameter name="maxExemptions" value="10" override="false"/>
</Context>
When I start tomcat, I get the following error:
Jul 27, 2011 4:38:38 PM org.apache.catalina.startup.HostConfig deployDescriptor
INFO: Deploying configuration descriptor context.xml
Jul 27, 2011 4:38:38 PM org.apache.tomcat.util.digester.Digester fatalError

2) Also tried using <Environment name="maxExemptions" value="10"
type="java.lang.Integer" override="false"/>, get the similar exception as before.
Is it possible to just provide the properties file path in server.xml or context.xml, so that tomcat would load it on startup? I have done this in JBoss using the properties-service.xml file giving it the path to properties file which gets loaded on startup and the app can just reference those variables.
Thanks

1. You are missing quotes around /app.
2. I believe the path attribute is not allowed in the files you were describing.
3. Since you are using tomcat, you could make use of one feature of the Digested, which is able to replace ${name} with Java system variables. Those can be set per tomcat instance.
