Hi Adam,
I got a similar Error, in my case the problem was that some of the
pathelements in webapp/lenya/bin/crawl_and_index.xml didn't match the
libraries in WEB-INF/lib.
Maybe you should take a look at the pathelement for the log4j
Library and verify that the referred file exists in your WEB-INF/lib.
best regards
Michael

Hi!!!
I got a big problem wit Lucene and I don't know how to resolve it.
Could someone explain how to make it work. I wanna crawl my site so I
executed the following command on my shell as explained in the official
website:
/home/webapp/web_software/lenya-1.2.2/tools/bin/ant -f
usr/local/tomcat/webapps/lenya/lenya/bin/crawl_and_index.xml
-Dcrawler.xconf=/usr/local/tomcat/webapps/lenya/lenya/pubs/AML-REGION/config
/search/lucene-live.xconf crawl
And this is the return:
Buildfile: /usr/local/tomcat/webapps/lenya/lenya/bin/crawl_and_index.xml
init:
[echo] INFO: Init
crawl:
[echo] INFO: Crawl and dump hypertext documents
(/usr/local/tomcat/webapps/lenya/lenya/pubs/AML-REGION/config/search/lucene-
live.xconf)
[echo] INFO: Show configuration
