Re: [xwiki-users] deleted wrong dir for solr...

Actually it looks like the "right" directory, that is "data/solr" If you remove (rename/move away) the data/solr directory (stopping the server before doing so and starting it afterwards) then on startup the server will recreate it, including a data/solr/lib/xwiki-platform-search-solr-server-plugin-6.4.jar with some necessary classes and stuff The class org.xwiki.search.solr.internal.EmbeddedSolrInstance however is in the webapps/xwiki/WEB-INF/lib/xwiki-platform-search-solr-api-6.4.jar and that file should better still be there, or you would have to reinstall XWiki 6.4. However it looks like there is some other error with the setup. Are there any other error messages in the log, either before or immediately after the error you posted? Any chance the data directory is not writeable by the user running XWiki or the like ? I can reproduce your error message by destructively doing a "chmod 000 data/solr". A few lines below I also get an error message saying " Caused by: java.lang.IllegalArgumentException: The given path [data/solr] must be a readable and writable directory" in the log. You might be able to find something similar that explains the root cause of the issue. Cheers, Clemens
