No you should only add one "djigzo.system.properties" parameter. The
context only seems to support just one parameter so you need to encode
the properties into one string (this is Tomcat shortcoming). Because the
properties need to be newline separated and XML does not directly
support a NL character you need to XML write the NL as 

So in your case I think the parameter value should look like:


Note: without any newlines (my mail app adds the newlines)

The reason you need to add "djigzo-web.spring.authenticator.config=" is
that it's a required system setting.

If you look at web.xml in the djigzo-web.war file the following section
does more or less the same thing:

    <!-- Use the default authenticator. -->

The only difference is that in web.xml you can use newline characters.
Now because you are overriding the "djigzo.system.properties" settings
in the Context you should also add the
"djigzo-web.spring.authenticator.config" setting in your properties
because all existing settings in web.xml will no longer be used.

Instead of specifying everything in the Context you can create multiple
copies of djigzo-web.war and change the web.xml contained in the war
files (a war file is just a zip with a different extension). I however
would prefer the Context approach because that only requires 'external'
