The DITA-OT Server is easily debugged by a local DITA-OT implementation, for example working on a oXygen plateform. For a server debugging, all intermediate steps are located in differents temporary directories.
No specific requirements: the DITA-OT tree structure needs to be the same onto the server and locally.
It may be useful to look at the files that Componize server will make available to the DITA-OT Server.
All the source files, the ditamap and anything referenced directly or
indirectly by the ditamap, are copied to a temporary folder on disk.
The temp directory of the Componize server,
contains folders named like
XProcPipelineService1518958057983166493.
It may also be usefull to look at the temp and
output directories of the DITA-OT Server.
The DITA-OT Server uses
it's own temp directory in foders such as :
/home/componize-temp/dita-ot/jobs/704/builds/1/temp.
The result is stored in folder such as or
/home/componize-temp/dita-ot/jobs/704/builds/1/out.
