Subject RE: It worked---NullPointerException while closing the index writer
Date Thu, 16 Feb 2006 09:05:47 GMT
Hi,

At least the re-indexing part worked....

I just removed the finally block and the NullPointerException was solved.:
          

 if (indexwriter != null)
            {
                System.out.println("going to close index writer");
                indexwriter.close();
            }
        } catch (IOException e)
        {
            e.printStackTrace();
            throw new Error(e);
        } finally
        {
            if (indexwriter != null)
            {
                indexwriter.close();
            }
        }
    }

Subject: NullPointerException while closing the index writer

Hi,

 

I couldn't fix the problem while creating an index, so I decided to clean
all the indexes from the server and try to re-index all my documents.

 

I am getting a NullPointerException, again while closing the index writer. I
don't know what I can be doing wrong while simply creating a fresh index.

 

The error log is as follows:

Any help will be much appreciated.

Subject: RE: ArrayIndexOutOfBoundsException while closing the index writer

 

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();

            }

        }

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:
