hi,
I am new to lucene. I want to build a search engine for myself, and use jboss(bundled with tomcat) as server. I wrote following code to do the index:
---------------------------code snippet---------------------------------
IndexWriter writer = null;
File root = new File(path);
DictionaryMgr dm = DictionaryMgr.getInstance();
HashMap dictionary = dm.getDictionary();
try {
String[] files = root.list();
if (files != null && files.length > 0) {
writer = new IndexWriter(path, new ChineseAnalyzer(dictionary), false);
}
else {
writer = new IndexWriter(path, new ChineseAnalyzer(dictionary), true); }
writer.maxFieldLength = 1000000;
writer.addDocument(doc);
}
--------------------------code snippet---------------------------------
when I use junit to test above code, there is no problem, but if this code work with JBOSS, it failed, very weird.
I check the code, and found the error lies in IndexWriter.java. it is the following code makes the error.
private org.apache.lucene.index.SegmentInfos segmentInfos = new org.apache.lucene.index.SegmentInfos();
but I don't think there is coding error, maybe error from JBoss, Tomcat or something else? I have no idea. so plx help me.
