[jira] Issue Comment Edited: (SOLR-2035) Add Velocity's ResourceTool to allow for i18n string lookups

["Erik Hatcher (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-2035?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12896878#action_12896878 ]

-------------------------------------------------------------

This patch adds a custom ResourceTool subclass to the Velocity context.   A custom subclass is needed in order to wire in SolrResourceLoader's ClassLoader facility.  

After applying this patch, a *path* needs to be added to SolrResourceLoader via solrconfig.xml, like this:

{code}
<lib path="./conf/velocity"/>
{code}

Then in conf/velocity, add a resources_en_US.properties file (or whatever your system default locale is) in the conf/velocity directory, something like this:

{code}
title=English Title
{code}

Then in a Velocity template, use:

{code}
$resource.title
{code}

See http://velocity.apache.org/tools/releases/2.0/javadoc/org/apache/velocity/tools/generic/ResourceTool.html for more details on how to use Velocity's ResourceTool.

*NOTE* This patch currently only works with the _default system locale_.  There's surely some way to allow configurability of the Locale, though nothing totally trivial jumped out at me on how to do it.

> Being able to look up string resources through Java's ResourceBundle facility can be really useful in Velocity templates (through VelocityResponseWriter).  Velocity Tools includes a ResourceTool.
