Deploying single .war file for use by multiple contexts - how do i override web.xml

[Steven Probetts <sp...@rtsystems.com.au>]

Hi all,

The problem is we have 4 different sub companies which we want to  
deploy a particular web app for.

What we want to do is stick a single .war file onto the server which  
all companies point to,
and set up different context.xml files for each (since they have  
different context data).

The problem is we also want different data (particularly the security  
role data) in the different web.xml files but these are stuck in  
the .war file.

So the question is:
Can we use the context file to alter the security role data (or more  
accurately override it) in the web.xml file depending on which  
company is using the web app.

Thanx in advance



Regards

Steven Probetts

Perhaps.  You can't override the web.xml settings, since that
information is defined by the servlet spec, and things in <Context> are
outside of the spec.  However, you could specify a different <Realm>
inside each <Context>, and that might suffice.  

You could also use a Filter to implement the necessary security,
possibly in conjunction with the web.xml settings.  I seem to recall
that there are some open-source security Filters already available that
have been mentioned in other threads.
