problem about the Opensim-Matlab interfaces

I downloand the MalabOpensimAPI.zip and want to test the interfaces.
Although I do as what the Readme.txt suggests, in the step 4(Close and restart Matlab)
when I restart the matlab,it pops a error: Cannot locate com/mathworks/jmi/OpaqueJavaInterface class.

the Opensim version is 2.4.0 , matlab is R2011b.

Does anyone know how to deal with it?

Thank you!

Hi Jianwei,

This may be due to an older installation of Matlab. Please check the Mathworks thread at

for troubleshooting tips,

Good luck

Hello,

I am getting this error message when trying to interface OpenSim 3.3 with Matlab:

Java exception occurred:
java.lang.NoClassDefFoundError: Could not initialize class org.opensim.modeling.opensimModelJNI

at org.opensim.modeling.Model.<init>(Model.java:119)

I ran the configureOpenSim script, imported the OpenSim libraries and tried the command model=org.opensim.modeling.Model(); as suggested. I removed OpenSim 3.2 from my path, and made sure the bin folder was a part of my current path with OpenSim 3.3

I have a 64-bit system but I am running 32-bit Matlab (student version), and have installed 32-bit 3.3.

Any help would be greatly appreciated.
