Convert Fuzzy model .fis file to Java package using Matlab Bulider JA

My Fuzzy model "myfuztest.fis" is working perfectly with 4 input and one output in fuzzy editor FIS. Also it is working fine when I run as .m file in Matlab.But The following error appears when I convert it into java package with the help of deploytool (Matlab builder JA). The build process is ok without error however when I run built application (that created by convertion) in Netbeans it gives following error

---------------------------------------------------------------------------"

*{Error using readfis (line 52)

The Matlab code is as follows

function out =  myfuztest2 (x)------%function get four input [0.1 150 3 13.9]
fismat =readfis('myfuztest.fis');-------- %read fuzzy file
out=evalfis (x,fismat);----   %store result after defuzzificztion

I have converted one Matlab tutorial matrix example (makesqr.m) file in java package and it is working fine. but the usage of .fis file in matlab gives error in conversion to java package . Any help would highly be appreciated.

Thank you very much for your kind answer, with the help of your excellent tips, I have fixed the error and now my fuzzy model that I have created in matlab is working fine in java netbeans.

 Actually  my .fis file was not shipped to java package at the time of deploytool running. I have just attached my .fis file with  shared resource and helper file  that is underneath of where we attach the .m file.

Once again thank you and appreciate your help.

Hi,

so the error is "Error using readfis (line 52) No such file or directory" which means that this call fismat =readfis('myfuztest.fis') dont work correctly.

Since this happens in the compiled code and you didn't took care off the path management take a look here:

http://blogs.mathworks.com/loren/2008/08/11/path-management-in-deployed-applications/

So make sure you provide the correct path to the 'myfuztest.fis' file. In the case this .fis file should be shipped with you compiled java package, attach this file as shared ressource and helper file in the deploytool.
