Hi Ken,
Very early on, some parameters were read from web.xml, and configured like so:
<context-param>
<param-name>solar.schema</param-name>
<param-value>schema.xml</param-value>
</context-param>
<context-param>
<param-name>solar.indexdir</param-name>
<param-value>index</param-value>
</context-param>
I'm not sure which is better, contex or init params (both are
available at init() time), but this is an alternative to the jindi
approach recently discussed.
The advantage to the jindi approach is that it doesn't require editing
of the Solr war, and hence easier upgrading - just copy it into place.
If there is a need, we could support both... it would just be a
matter of deciding which config had precedence in the case that
multiple mechanisms are used.
