Error loading class 'solr.extraction.ExtractingRequestHandler'

genebobmiller opened this issue 6 years ago · 12 comments

When attempting to index file attachments using the Drupal module 'search_api_attachments', it was discovered that the following error is being thrown inside the solr container:

I believe this is caused by the path to apache-solr-cell-\d.*.jar or /extraction/lib being incorrect in the solrconfig.xml

Does it work when you change it to /opt/solr/contrib/extraction/lib/?

Answer 2 · 2019-03-01T00:15:16.000Z

No that didn't work, I found that there was no apache-solr-cell.jar in the
/opt/solr/contrib/extraction/lib folder.

What did work was replacing line 90 of the solrconfig.xml with the following:

<lib dir="/opt/solr/dist/" regex="solr-cell-7.5.0.jar" />

Anything I can do to assist further in moving this forward?

I see there's the line that seems to be the same thing as what you replaced with:

  <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-cell-\d.*\.jar" />

Maybe there's something wrong with ${solr.install.dir:../../../..} but I doubt, because it used everywhere and it somehow works.

I see this line

<lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-cell-\d.*\.jar" />

in the search_api_solr_8.x config sets but it is missing from the search_api_solr_7.x config sets.

Answer 6 · 2019-03-28T07:31:39.000Z

I guess that's something that should be reported to search_api_solr 7.x

Answer 7 · 2019-03-29T02:22:54.000Z

Could be, I'll leave that in your capable hands and look forward to this issue being resolved.

We've made the fix, could you please test the latest version

Answer 9 · 2019-04-01T03:17:01.000Z

Despite several warnings on the creation of a core such as:

Couldn't add files from /opt/solr/server/solr/configsets/search_api_solr_7.x-1.14/../../../contrib/extraction/lib filtered by null to classpath: /opt/solr/server/solr/configsets/search_api_solr_7.x-1.14/../../../contrib/extraction/lib

This is now correctly indexing file attachments!

Answer 10 · 2019-04-01T04:34:54.000Z

Cannot reproduce, what is the solr version and config set? How do you create a core?

Answer 11 · 2019-04-01T05:18:25.000Z

From my docker-compose.yml (irrelevant lines removed):

    build:
      context: ./wodby-solr
      args:
        BASE_IMAGE_TAG: 7.5.0-alpine
        SOLR_VER: 7.5.0
    environment:
      SOLR_DEFAULT_CONFIG_SET: search_api_solr_7.x-1.14
      SOLR_HEAP: 1024m

core created with:

make core=wodby -f /usr/local/bin/actions.mk

from inside the solr container.

Answer 12 · 2019-04-01T07:46:19.000Z

Fixed in 3.1.0
