plx help for a weird problem

2004-10-22 Thread Slide Tao 
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 = 100;
	  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.
