URL: https://issues.apache.org/jira/browse/SOLR-3244
Project: Solr
Issue Type: Bug
Components: web gui
Affects Versions: 4.0

I am currently unable to open admin interface when using war deployment under
tomcat server.
The stack trace:

I did some debugging and found that the problem related that
it delegates the resolving of resource path to the
org.apache.naming.resources.WARDirContext which simply returns null for any
input parameters:
/**
* Return the real path for a given virtual path, if possible; otherwise
* return <code>null</code>.
*
* @param path The path to the desired resource
*/
@Override
protected String doGetRealPath(String path) {
return null;
}
Need to check specification, because it may be actually the tomcat bug.
