Re: 'Parametrizing' context.xml?
How can the variable (i.e. here BPVAL be set)? E.g. in server.xml? Is
<context-param> really in context.xml? Looks more like web.xml to me.

Are you sure that the context.xml you're modifying is the one being used? If there's a <Context> element in conf/Catalina/[host]/[appName].xml, that will override the one in your webapp's META-INF/context.xml file.

Ok, adding a line in catalina.properties seems to set the value at least. It
appears, when I call System.getProperties() inside the Java code. However, I
still could not find out, how to access the variable in context.xml.

Ok, I have added the line
DBVAL=mydb_dev
to catalina.properties.
Now I define a Realm in my webabb's context.xml:
<Realm className="org.apache.catalina.realm.JDBCRealm"
driverName="org.postgresql.Driver"
connectionURL="jdbc:postgresql://myserver:5432/${DBVAL}"
connectionName="xxx" connectionPassword="yyy"
userTable="users" userRoleTable="roles"
userNameCol="name" userCredCol="pw" roleNameCol="role"
digest="MD5" />
However, in the logfiles I can find:
org.postgresql.util.PSQLException: FATAL: database "${DBVAL}" does not exist
It seems, that the parameter value was not replaced.
What I would like to have is to define a Realm once in context.xml, that
will be used both on a development and on a productive server. The servers
define the actual name of the database (here "mydb_dev"), e.g. in
catalina.properties.

I think it was just an example. Would you prefer <Resource
param="${BPVAL}" />?
