Er, in fact I don't think dataDir is a special thing... I think any JNDI
configuration is special thing, if it has the same meaning with a system
property.
The dataDir is just a example --- I added it just because it's the only
specificated one in the wiki document.
But I opposite to the concept of refering properties and JNDI values in
different syntax...
for example, if <dataDir>${java:comp/env/solr/home}/data</dataDir> and
<dataDir>${solr.solr.home}/data</dataDir> are both supported
which is the one I should put into the solrconfig.xml?
There might be two solr servers using this configuration... one of them has
a JNDI home, and the other one is started from command line.
I think the problem is what we needed in configuration files is not a
parameter from somewhere, but a server's status in fact.
The server can be installed with a console parameter, with a JNDI context
file, or with hardcode in web.xml, it's doesn't matter.
I just want to know where the server's home is.
So, we either map both the JNDI value and system property into a same system
status variable, or just use properties to do this, and map JNDI values to
it.
That's why I only enabled JNDI lookup in property values.
If you think hardcode mapping into Config.java is to ugly, maybe a mapping
properties file in solr home dir will be a better choise?
Anyway, thanks for replying
I guess the property syntax will need to be changed a bit because ':' is
Yes, I totally agree with this.

> I would like to be able set the solr.data.dir with JNDI, as I can for the
> solr.home property. Currently the data directory is only looked up in the
> ${solr.home}/conf/solrconfig.xml file, or as a parameter passed into the
> SolrCore(String, IndexSchema) constructor.
> This allows more options for setting the data directory, such as from within
> a Servlet container's Context fragment.
