I have inherited a project which is using solr. When it loads it fails with this error:

```

```

In my projects I cannot find a solconfig.xml - and am struggling to determine where this file should be and what its contents by default would be.

I have found : <http://wiki.apache.org/solr/SolrConfigXml> which may give me a starting point but what directory in which JEE application am I placing this file? I have a solr project web app, and some other apps which appear to be classes only.

Please offer some guidance.
