Thanks for the response.
I was trying this in my search.jsp:
import="org.apache.nutch.crawl.*"
...
crawldbreader = new CrawlDbReader(nutchConf.get("searcher.dir") + "
-stats");
I believe that dumps to stdout, but I'd worry about the output format after
I got through the error: /_search.java : 383 : The constructor
CrawlDbReader(String) is undefined

In short, no I don't know. What I do know is that passing
'nutch-1.2/bin/nutch crawl/crawldb -stats' would not give you any results,
I
think you would get a output of all possible commands and how to call them.
The command you are referring to is readdb which is an alias for
o.a.n.crawl.CrawlDbReader, take a look at this class and try to figure out
how you could access the stats data.

If you look (for example) at the ontology plugin which shipped with Nutch
1.2, this plugin was used only within the webapp, however various
configuration options also had to be configured within the WAR file used
within the servlet container as was the same with the index dir of your
Lucene index. This is the type of functionality you would require to get
crawldb stats output however I'm afraid I am no more information sorry.
