NullPointerException in DataImportHandler
First of all, apologies if you get this twice. I posted it by email an hour
ago but it hasn't appeared in any of the archives, so I'm worried it's got
junked somewhere.
I'm trying to use a DataImportHandler to merge some data from a database
with some other fields from a collection of XML files, rather like the
example in the Architecture section here:
http://wiki.apache.org/solr/DataImportHandler
... so a given document is built from some fields from the database and some
from the XML.
My dataconfig.xml looks like this:
<dataConfig>
<dataSource name="database" driver="org.postgresql.Driver"
url="jdbc:postgresql://cathdb.info/cathdb_v3_3_0" user="cathreader"
password="cathreader" />
<dataSource name="filesystem" type="FileDataSource"
basePath="/cath/people/cathdata/v3_3_0/pdb-XML-noatom/" encoding="UTF-8"
connectionTimeout="5000" readTimeout="10000"/>
<document name="domain">
<entity name="domain" dataSource="database" query="select domain_id
as id, 'PDB code ' || pdb_code || ', chain ' || chain_code || ', domain ' ||
domain_code as title, 'some keywords go here' as
keywords, pdb_code || ' ' || chain_id as related_ids, 'domain' as doc_type,
pdb_code from domain">
<entity dataSource="filesystem" name="domain_pdb"
url="${domain.pdb_code}-noatom.xml">
<field column="content"
xpath="//*[local-name()='structCategory']/*[local-name()='struct']/*[local-name()='title']"
/>
</entity>
</entity>
</document>
</dataConfig>
This works if I comment out the inner entity, but when I uncomment it, I get
this error:
30-Jul-2009 14:32:50 org.apache.solr.handler.dataimport.DocBuilder

I have checked that the file
/cath/people/cathdata/v3_3_0/pdb-XML-noatom/1s32-noatom.xml is readable, so
maybe the full path to the file isn't being constructed properly or
something?
I also tried with the full path template for the file in the entity url
attribute, instead of using a basePath in the dataSource, but I get exactly
the same exception.
This is with the 2009-07-30 nightly build. See attached for schema.
http://www.nabble.com/file/p24739580/schema.xml schema.xml
Any ideas? Thanks in advance!
Andrew.

It's very easy to write your own entity processor. At least, that is my
experience with extending the SQLEntityProcessor to my needs. So, maybe
you'd be better off subclassing the xpath processor and handling the
xpath in a way you can keep your configuration straight forward.

I got it working with:
<entity dataSource="filesystem" name="domain_pdb"
url="${domain.pdb_code}-noatom.xml" processor="XPathEntityProcessor"
forEach="/datablock">
<field column="content"
xpath="/datablock/structCategory/struct/title" />
</entity>
Now, to get it to ignore missing files without an error... Hmm...

Re: NullPointerException in DataImportHandler

Hi Andrew,
my experience with XPathEntityProcessor is non-existent. ;-)
Just after a quick look at the method that throws the exception:
private void addField0(String xpath, String name, boolean multiValued,
boolean isRecord) {
List<String> paths = new
LinkedList<String>(Arrays.asList(xpath.split("/")));
if ("".equals(paths.get(0).trim()))
paths.remove(0);
rootNode.build(paths, name, multiValued, isRecord);
}
and your foreach attribute value in combination with the xpath:
> forEach="/">
> <field column="content"
>
xpath="//*[local-name()='structCategory']/*[local-name()='struct']/*[local-name()='title']"
> />
I would guess that the double slash at the beginning is not working with
your foreach regex. I don't know whether this is something the processor
should expect and handle correctly or whether you have to take care of
in your configuration.
Cheers,
Chantal

it does not use javax.xml because those work on a DOM tree which is
not usable for large xml files.
This only supports a subset of xpath. The supported syntax is given here

Sadly not...
I tried with:
<field column="content"
xpath="/datablock/structCategory/struct/title" />
(full path from root)
and
<field column="content"
xpath="//structCategory/struct/title" />
Same ArrayIndex error each time.
Doesn't it use javax.xml then? I was using the complex local-name
expressions to make it namespace-agnostic -- is it agnostic anyway?
Thanks,
Andrew.

The XPathEntityProcessor doesn't support that fancy of an xpath - it
supports only a limited subset. Try /structCategory/struct/title
perhaps?

since each XML file contains the information for no more than one document.

Re: NullPointerException in DataImportHandler

Hi Andrew,
your inner entity uses an XML type datasource. The default entity
processor is the SQL one, however.
For your inner entity, you have to specify the correct entity processor
explicitly. You do that by adding the attribute "processor", and the
value is the classname of the processor you want to use.
e.g. <entity dataSource="filesystem" name="domain_pdb"
processor="XPathEntityProcessor" ....
(See the wikipedia example on the DataImportHandler wiki page.)
Cheers,
Chantal
