Java library failed to load while trying to interface with MATLAB

[Karthick Ganesan]

Dear All,
I tried to interface opensim with matlab. I followed the procedure given in the documentation page (manual as well as running the configureOpenSim script). While running sample code (simple optimizer example), It failed to load the java library. My opensim install directory\ bin is in the system path. Here is the screenshot of the error. Please give your suggestions to resolve this issue. Matlab version is R2015b.

Does your system path refer to more than one installation of OpenSim? Please see topic 5963 (viewtopicPhpbb.php?f=91&t=5963).

Thanks for your reply. Yes. I had multiple versions in the system path and I removed the older versions from the path. Now I get the following error.
Error using simpleOptimizerExample (line 31)
