trying to execute "javaaddpath" from c++ compiled .m file.

I am calling a compiled .m file from my c++ program that executes "javaaddpath". Upon execution of this line of code, the error statement: [??? Undefined variable "com" or class "com.mathworks.jmi.ClassLoaderManager.getClassLoaderManager"]. I initialize the shared object with my .m file using mclmcrInitialize() followed by if(!mclInitializeApplication(mcc_args, 1)) where mcc_args is "-nodisplay". When I startup matlab manually separate from my c++ application, I see that "com.mathworks.jmi.ClassLoaderManager" exists upon start-up. What do I need to do to have it exist when my compiled .m file executes in my c++ program?
