MATLAB: importing java libraries

I have the following lines in my MATLAB code:

javaaddpath('C:\Users\localadmin\SkyDrive\IdeaProjects\DrawModels\out\artifacts\DrawModels_jar\DrawModels.jar')
javaaddpath('C:\Users\localadmin\SkyDrive\IdeaProjects\DrawModels\out\artifacts\DrawModels_jar\itextpdf-5.4.1.jar')

I then go on to instantiate some JAVA objects defined in the files.

I would like to copy the JAR files to where the .m file sits, and then write the following instead (i.e. I want to use a relative path rather than an absolute one).

javaaddpath('DrawModels.jar')
javaaddpath('itextpdf-5.4.1.jar')

However, the MATLAB path doesn't seem to apply to javaaddpath and so the JAR files do not get loaded.

Any ideas as to how I may achieve a relative path addressing of JAR files?

The background for this is I want the MATLAB code to run both on Windows and Linux, i.e. whereever it is unpacked. The user may unpack it in any folder he chooses, so I don't want a hard-coded path in the source.

Any help appreciated.

You can use mfilename to find the path of the running M file, which you can concatenate with the JAR file name like,

javaaddpath(fullfile(fileparts(mfilename('fullpath')),'DrawModels.jar'))

That must go in the M file with which you would like to add the Java class to MATLAB.
