Hi Erick, I still need your advice. The program I have to fix uses class AutoDetectParser along with Solrj for parsing PDF files before sending the result to the solr server. To do this it linked two tika jar files taken from the solr distribution. Namely: tika-core and tika-parsers. Maybe it used some other tika related files but I have problems to identify them among a lot of other jar files linked. The program worked more or less OK, but it gave too many warnings of kind "Font not found". I had a rumor that this was fixed in the next tika distribution. I switched from Solr 7.5 to solr 7.7.1 in a hope that will solve that problem. However when I switched I encountered an another problem: java.lang.NoClassDefFoundError: org/apache/cxf/jaxrs/ext/multipart/ContentDisposition. Apparently I have not included some necessary jars. Those jars supposed to come from a different project called cxf, but because they are related to tika I expected them be distributed with solr. However I did not find them in the solr 7.7.1 (in the solr 7.5 as well). I have found the necessary file in the cxf distribution and included it. It asked for an another file which I included as well. After this I got a message that some temporary resources were not closed. Apparently something is not matched. And now I am stuck. I do not want to start from scratch and search the whole tika and cxf projects for the files I need and I do not want to include all files from those projects especially because I was not able to find a binary distribution. So could you please advise what is the best way to proceed.

Look in: ./solr/contrib/extraction/lib Tika is upgraded when new versions come out, so the underlying files are whatever are current at the time. The integration is a fairly loose coupling, if you're using some external program (say a SolrJ program) to parse the files, there's no requirement to use the jars distributed with Solr, use whatever suits your fancy. An external program just constructs a SolrDocument to send to Solr. What you use to create that document is irrelevant. See: https://lucidworks.com/2012/02/14/indexing-with-solrj/ for some background. If you're using the ExtractingRequestHandler, where you just send the semi-structured docs to Solr (PDFs, Word or whatever), then needing to know anything about individual Tika-related jar files is kind of strange. If your predecessors wrote some custom code that runs as part of Solr, I don't know what to say...
