No method 'put' with matching signature found for class > 'java.util.Hashtable'. That's indeed problematic. Java does not have a native type that corresponds to a Matlab struct. You can either create a Java class that maps to the struct, or if you have Matlab R2008b (7.7) or later you can use the built-in containers.Map function, which is a scaled-down Matlab version of the java.util.Map interface. Also see: http://stackoverflow.com/questions/436852/storing-matlab-structs-in-java-objects Note that the recently-released R2010a (7.10) added a containers.Map functionality of specifying the expected data types.
