Working through this we have discovered we were using different commands, which then uncovered an error in the example on the TikaJAXRS wiki page where all examples, regardless of the nature of the content, use the -d flag (effectively --data-ascii) in the curl commands. This means that binary files are being processed as ASCII content. Based on the above, all that was required was to change the command from: curl -X PUT -d @GeoSPARQL.pdf http://localhost:9998/tika --header "Content-type: application/pdf” To: curl -X PUT --data-binary @GeoSPARQL.pdf http://localhost:9998/tika --header "Content-type: application/pdf” I have updated the TikaJAXRS wiki page accordingly but felt it was worth posting back to the list for future reference. Cheers, Dave
