TDM/TDMS Java Interface?

[Derek256]

Hello there, has anyone developed an interface in Java that can read TDM and TDMS files?  From all the googling and poking around on NI's site, my gut feeling is no, but I just wanted to ask anyway just to be sure. I see there is a Java Header Writer (http://zone.ni.com/devzone/cda/epd/p/id/6280), existing questions about external interfaces (http://digital.ni.com/public.nsf/allkb/A3663DE39D6A2C5A86257204005C11CA), and pre-existing C and Excel readers, but I can't see any mention of a Java API for reading these files.

If there isn't, I'm just looking for a confirmation that there isn't, and whether or not one might be developed in the future.  If there isn't, how are other people solving this problem?  Using JNI with the C library to get TDM(S) data into Java apps?  

Thank you kindly for your support.

Derek

PS: I didn't know where to post this as I did not see a separate TDM category. Thanks.

Here is a post of "TDM Header Writer Java API":

If there's no available API for reading, then it seems you have to make your own API based on the file formats, for TDMS, the file format structure is here:

Hello Derek,

You should be able to call the TDMS C DLL in your Java application.

Thanks to you both for responding.  This information is essentially what I was looking for, that a Java API for reading does not exist and what options I have for proceeding.  I'll either have to write my own Java reader, or call the C libraries from Java.  Thanks!

Hi,

Is the situation still same in 2018 ?. We still have no Java API/library to read .TDMS file.

I am looking for a library which can read the .TDMS file for automating the test results.
