Hi Otis,
Thanks for such a quick reply. I tried using finally, but it didn't help.
I guess if I explain the integration of lucene with my app in little detail
then you probably can help me better.
I allow users to upload documents, which are then indexed, and search on
them. Now I am getting this error when I am trying to index the document and
particularly while closing the index writer.
If we look closely at the error log, it's giving an error at
org.apache.lucene.index.FieldInfos.fieldInfo(FieldInfos.java:135)
i.e., when lucene tries to get something by the field name,
return (FieldInfo) byName.get(fieldName);
, now what beats me is that, indexing on fields has already been done by the
time we want to close the index writer, so how come I don't get an error
while indexing, what goes wrong when I am trying to close the index writer.
Please see if you can help me with this....
Thanks in advance.
The code used for indexing is as follows:
public void indexFile(IndexWriter indexwriter, File resumeFile)
{
Document document = new Document();
try
{
File afile[] = indexDirFile.listFiles();
boolean flag = false;
if (afile.length <= 0)
flag = true;
indexwriter = new IndexWriter(indexDirFile, new
StandardAnalyzer(), flag);
try
{
document.add(Field.Text(IndexerColumns.contents, new
FileReader(resumeFile)));
} catch (FileNotFoundException e)
{
e.printStackTrace();
throw new MyRuntimeException(e.getMessage(), e);
}
document.add(Field.Keyword( IndexerColumns.id,
String.valueOf(mapLuceneParams.get(IndexerColumns.id)) ));
for (int i = 0; i < this.columnInfos.length; i++)
{
ColumnInfo columnInfo = columnInfos[i];
String value =
String.valueOf(mapLuceneParams.get(columnInfo.columnName));
if (value != null)
{
value = value.trim();
if (value.length() != 0)
{
if (columnInfo.istokenized)
{
document.add(Field.Text(columnInfo.columnName,
value));
} else
{
document.add(Field.Keyword(columnInfo.columnName,
value));
}
}
}
}
document.add(Field.Keyword(IndexerColumns.filePath,
String.valueOf(mapLuceneParams.get(IndexerColumns.filePath))));
try
{
indexwriter.addDocument(document);
} catch (IOException e)
{
e.printStackTrace();
throw new MyRuntimeException(e.getMessage(), e);
}
indexwriter.close();
} catch (IOException e)
{
e.printStackTrace();
throw new Error(e);
}finally
{
if(indexwriter != null)
{
indexwriter.close();
}
}
Regards,
Shivani

Who knows what else the app is doing.
However, I can quickly suggest that you add a finally block and close your
writer in there if writer != null.

Subject: ArrayIndexOutOfBoundsException while closing the index writer
Hi,
I have used Lucene in my application and am just indexing and searching on
some documents. The code that indexes the documents was working fine till
yesterday and suddenly stopped working.
I get an error when I am trying to close the index writer. The code is as
follows:
.
IndexWriter indexwriter = new IndexWriter(indexDirFile, new
StandardAnalyzer(), flag);
indexFile(indexwriter, resumeFile);
indexwriter.close(); //causing errors
} catch (IOException e)
{
e.printStackTrace();
throw new Error(e);
}
.
And the error log is as follows:
2006-02-15 18:47:48,748 WARN [org.apache.struts.action.RequestProcessor]
Unhandled Exception thrown: class java.lang.ArrayIndexOutOfBoundsException
