A strange Error--IllegalAccessError: tried to access field org.apache.lucene.search.IndexSearcher.reader
Hi.
I get a strange problem with my web application recentlly. The webapp runs under:
resin-2.1.10
j2sdk1.4.2_01
redhat linux 2.4.20
I use a subclass of IndexSearcher, IndexOrderSearcher, search the index, and output the result use a servlet. The webapp works fine the most time, but, about half a month ago, I got the following error when I restart resin:
500 Servlet Exception
java.lang.IllegalAccessError: tried to access field org.apache.lucene.search.IndexSearcher.reader
from class org.apache.lucene.search.IndexOrderSearcher
at org.apache.lucene.search.IndexOrderSearcher.search(Unknown Source)

at java.lang.Thread.run(Thread.java:534)
But After the server rebooted, everything gets right again.
I have suspected that all applications runing in just one JVM causes the Error, so I separated the applications with multiple JVMs, but the problem remains. Can anybody give me some clue about this Error?
Thanks!

You can store the unique id in the index. Also you can store in the
index all info for results.
For example(sorry for C# syntax):
Field.UnIndexed("id", id );
Field.UnIndexed("title",title_str);
Field.UnIndexed("description",description_str);
Field.Text("value",completeValue);
We search by "value field" and show "title" and "description" fields in
results without database connection.
Also we have "see detail" link with "id" field as parameter of link.
Example:
Title: Lucene
Descriptoon: The full text search engine
Detail: http://lucene.net/detail?value=12345
12345 - document id from database.
We do not store real value int the index, only index it.

Lucene wiht Database??
Posted by "Garg Raman (SDinc)" <ra...@smartdatainc.com>.
Hello,
I am new to Lucene and want to use it in my web application. Our client will have very large DB on PostGre and what we need is to use Lucene for search purpose. It should give us the rank of search also.
My problem is I can't found the method on How to Integrate Lucene with a Database table. Please give any advice. Thanks in Advance
Thanks

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!

Please note that the class that caused the error,
org.apache.lucene.search.IndexOrderSearcher, is not really a Lucene
class. You got that class from http://sf.net/projects/weblucene, most
likely.
