    Hi, indexing is working fine until i check it to index application/pdf. Then i get the error message below. I have been searching this forum without any results. I dont get this message on my local environment where i run ubuntu 14.04 but i do get the error on my production environment where i run Debian 7.

    Which Solr files version do you use ?

    See
    https://www.ads-software.com/support/topic/error-when-trying-to-index?replies=7,
    and especially
    https://stackoverflow.com/questions/27058991/solr-tomcat-org-apache-solr-common-solrexception-lazy-loading-error

    It seems you’re adding a source directory to the classpath – you’ll need to add the compiled version with its dependencies to the classpath instead.

    In the normal distribution (from the Solr homepage) this is located in contrib/extraction/lib, where it also bundles the other dependencies for the extraction module.

    I think i run 5.5.1. Ok let me try that.

    (@bjorngus)

    I have on the server in
    /opt/solr-5.5.1/contrib/extraction/lib
    all the .jar files, does this means i have the compiled version ? And where do I add the source to the complied version?

    And do i need to go trough all this guide ?

    Here is my complete procedure, tested a few minutes ago:

    wget https://archive.apache.org/dist/lucene/solr/5.5.1/solr-5.5.1.tgz
tar xvf solr-5.5.1.tgz
solr-5.5.1/bin/solr start
solr-5.5.1/bin/solr create -c wpsolr-5.5.1

(download solr 5.xx config files from https://wpsolr.com/releases/#1.0)
cp solrconfig.xml schema.xml solr-5.5.1/server/solr/wpsolr-5.5.1/conf/
(reload index with solr admin UI)
(configure a new index in wpsolr admin UI:
Index name: wpsolr - local 5.5.1
Solr Protocol: http
Solr host: localhost
Solr port: 8983
Solr path: /solr/wpsolr-5.5.1
)
(index posts on wpsolr admin UI, including a pdf file)
(search in posts, retrieve the pdf)

    Thanks, but now im getting

    Solr HTTP error: OK (404) <html> <head> <meta http-equiv=”Content-Type” content=”text/html; charset=UTF-8″/> <title>Error 404 Not Found</title> </head> <body><h2>HTTP ERROR 404</h2> <p>Problem accessing /solr/berotec/select.

    I saw in a previous post in this forum i should edit my path, where do i do that, i looked in solrconfig.xml but dont find where.

    One more thing, on my local environment i can access mysite:8983 but not on production, can i reload index without solar admin UI ?

    (@wpsolr)

    Within your Solr admin UI, select your index, and query it. It will show you a full url like

    https://localhost:8983/solr/berotec/select?q=*%3A*&wt=json&indent=true

    Is it ?

    Thread Starter bjorngus

    (@bjorngus)

    i cant access my solar admin on my production site, i dont know why, it times out. Maybe it has some port forwarding.

    Plugin Author WPSolr free

    (@wpsolr)

    iptables ?

    Thread Starter bjorngus

    (@bjorngus)

    I think portforwarding, but dont know much about it, anyway
    In another post here, it says:

    I didn’t have to put in the entire path:
    /opt/solr/server/solr/hitlink
    It ended up being:
    /solr/hitlink

    Where do i edit this ?

    Plugin Author WPSolr free

    (@wpsolr)

    In wpsolr, Solr path of your index

    ok, i changed back to my previous installation of solr, and now it works and i dont get the java error. Even though i dont think i changed anything. Thank you for all your help.
