I\'m ussing the Appache Jackrabbit JCA 2.7.5, the problem is that files .docx and .xlsx is not indexed.
My steps :
The solution is focused on JARs of the jackrabbit-jca-2.7.5.rar!
There are errors on dependency so I make these change :
Add these JARs in the jackrabbit-jca-2.7.5.rar before deploying this!
And the indexation of .docx, .xlsx, ... wors succesfully!
Thank you for @Ashok Felix
