I've got an existing Spring Solr SolrJ application that indexes a mixture of
documents. It seems to have been working fine now for a couple of weeks but
today I've just started getting an exception when processing a certain pdf
file.
The exception is :
ERROR: org.apache.solr.core.SolrCore - org.apache.solr.common.SolrException:

With a bit of investigation it seems that this error was in pdfbox 0.7.3 and
was fixed in 0.8. See
http://osdir.com/ml/tika-dev.lucene.apache.org/2009-09/msg00037.html
Looking at my libraries it seems I am using pdfbox 0.7.3. I am using maven
for building and pdfbox 0.7.3 appears to have come from the tika-parsers 0.4
pom file which in turn appears to have come solr-cell 1.4.0 pom file. In my
project's maven pom file I have the following entries and don't explicitly
specify pdfbox or a particular version :
<dependency>
<artifactId>solr-solrj</artifactId>
<groupId>org.apache.solr</groupId>
<version>1.4.0</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
<dependency>
<artifactId>solr-core</artifactId>
<groupId>org.apache.solr</groupId>
<version>1.4.0</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.apache.solr</groupId>
<artifactId>solr-cell</artifactId>
<version>1.4.0</version>
</dependency>
Can anyone confirm that a maven build for Solr 1.4 brings in pdfbox 0.7.3,
as I'm wondering whether if there is a problem with my maven set up? If I
am correct can anyone advise as to what I need to do to get the right
version of pdfbox, apart from editing my pom file locally?
Thanks
Shaun
