Subject Re: A strange Error--IllegalAccessError: tried to access field org.apache.lucene.search.IndexSearcher.reader
Date Wed, 15 Oct 2003 10:42:09 GMT
Otis:
Yes, it's not a problem of lucene, IndexOrderSearcher is a class of weblucene, it extends
IndexSearcher. According to the lucene's javadoc, the subclass of IndexSearcher should have
access to IndexSearcher.reader field, because there is no specifier before the field 'reader'.
Now my problem is the weblucene works fine the most time, but about half a month ago the problem
happened, even if my webpp runs under a separated JVM.
May the modification of the server's setting causes the problem, but I'm not sure, or may
be I shouldn't post the message here -- please pardon me, I really want to get some clues
about the error. Thanks!
