I am setting up Virtual Hosts. In my server.xml I have entries like
<Server ...>
<Service ...>
<Engine...>
...
<Host name="sample1" appBase="SampleApps1"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false"/>
<Host name="sample2" appBase="SampleApps2"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false"/>
...
</Engine>
</Service>
</Server>
Each of the Virtual Hosts will have one or more Contexts. I am concerned about
the Context declaration for my Web Application which is nested in the directory
structure under $CATALINA_HOME/conf.
I am setting this up so that each virtual host shares the same document base
(i.e., it is the same application in different contexts). Each virtual host
has a root.xml that looks something like
<?xml version='1.0' encoding='utf-8'?>
<Context displayName="sample1" docBase="../SciHealthDocBase" path=""
workDir="work/Catalina/sample1/_">
<Parameter name="ClientName" value="Doc" override="false"/>
<Parameter name="AppBase" value="../SampleApps1/" override="false"/>
</Context>
The getRealPath() method of my ServletContext gives me paths relative to my
docBase. I need a way to access directories within my appBase so that I can
place dynamically created content within those directories. I am doing this
right now by defining a Context Parameter that has a relative path hard coded.
Not so bad but I have to make sure I modify this file correctly for each
virtual host setup.
Since the Context declaration is being loaded as part of a Virtual Host I was
hoping to be able to refer to the appBase attribute of the Host entry to make
my Context declaration more robust.
Thanks,

Can you kind of "unwind" that sentence, or provide an example, so that
we mere mortals would understand what you mean ?
