-------------------------------------
Could someone JNDI-savvy comment here? Or kill this issue..
> Add Ability To Use JNDI Keys In Configuration String Replacement Tags
> ---------------------------------------------------------------------
>
> Key: SOLR-992
> URL: https://issues.apache.org/jira/browse/SOLR-992
> Project: Solr
> Issue Type: Improvement
> Affects Versions: 1.4
> Environment: jdk 1.6.x, Tomcat 5.x, 6.x
> Reporter: Michael Henson
> Priority: Minor
> Attachments: solr-992.zip

> The configuration syntax allows users to specify tags which will be replaced
> with values pulled from system properties, or a given default value if the
> system property can not be found. It could also be useful to allow users to
> pull replacement values from the JNDI environment configuration.
> Issues:
> 1. Full JNDI tags are specified with a url syntax, which includes a ":"
> character. The ":" character is currently used to separate the system
> property name to be used for replacement from the (optional) default value to
> use.
> 2. JNDI might not be configured for the application's context at all.
> 3. The specified JNDI reference might not be found in the application's
> context.
> 4. The specified JNDI reference might be malformed.
> The attached patch is a simple first-draft attempt to merge the code used to
> pull a value for solr.home from JNDI into the variable replacement utility.
> The syntax I went with for determining that it's a JNDI replacement key is to
> require a "jndi/" prefix, where anything following that prefix is expected to
> be a "/"-delimited JNDI path: "jndi/data/home".
> I had to comment out the log references because there is no log object
> available in the DOMUtil. I also had to replace the reference to "project"
> with its defined value, since that variable is just a final static String in
> the SolrResourceLoader class anyway.
