Inside the OPenMINTED project we have integrated the FreeLing parser within the UIMA framework
In github there is the code of the wrapper and a sample program to read/write XMI or txt files, analyze them with FreeLIng and produce as output XMI files with the corresponding annotations
Also there is a docker that already includes FreeLing and the wrapper. The docker processes all the files in an input folder and leaves the processed files in the output folder.
You can find them here, the github repository:
https://github.com/TalnUPF/OpenMinted_Freeling
and the docker:
https://hub.docker.com/r/taln/openminted_freeling/

enjoy it!
