ClassNotFoundException in serialization code

I wrote out a data file using a Java class that implement java.io.Serializable. When I tried to read the file in MATLAB, there are "Java exception occurred: java.lang.ClassNotFoundException: com/mycompany/matlabtest/TestData$DataType"

I added the jar file to the MATLAB using javaaddpath.

The code I used to read it is fin = java.io.FileInputStream('C:\matlabtest.dat'); ois = java.io.ObjectInputStream(fin); dtype = ois.readObject();

Is it possible for me to read the proprietary file? I can change the Java code that creates the files. Thanx.

I don't know if this means anything, but I can create the Java object (the type that the readObject() command I expected to return) in MATLAB by using the following command:

newobj= javaMethod('valueOf','com.mycompany.matlabtest.TestData$DataType','SINGLE');
