Q: When I try to introduce the jar file to matlab, I get the following error.

??? Undefined variable "com" or class "com.mathworks.jmi.ClassLoaderManager.getClassLoaderManager".

Error in ==> javaclasspath>local_javapath at 114
jloader = com.mathworks.jmi.ClassLoaderManager.getClassLoaderManager;

Error in ==> javaclasspath at 62
      p = local_javapath('-dynamic');

Error in ==> javaaddpath at 69
  javaclasspath( p, javaclasspath );

Error in ==> jd at 3
javaaddpath ( '/home/jevans/matlab/classes/toolsUI-2.2.16.jar' )     ;

                

A: Most likely you started MATLAB with the -nojvm option. Try it with the -nodesktop option instead.
