problem in deploytool when i convert m file to java ?

i write m file that content codes like this :-

% Browse for the image file. 
[baseFileName, folder] = uigetfile('*.*', 'Specify an image file'); 
fullImageFileName = fullfile(folder, baseFileName);

when i use deploytool to convert this m file so i can run it in java i get error because i cant run this code but if the code doesn't has any process with images it runs well

why?
