I am currently running a Java application which applies some natural language processing techniques to analyze data. This application includes a Java Class file and 1 library of .bin extension The application works fine on my development server but on the live server I get the error below:
Object instantiation exception.
An exception occurred while instantiating a Java object. The class must not be an interface or an abstract class. Error: opennlp/tools/util/ObjectStream.

It seems to me that it’s a class path issue. I had the same problem with the Dev server but fixed it by placing all my files in the Cold Fusion 9 directory: C:\ColdFusion9\runtime\servers\lib
When I place the class file and library .bin file in the same folder on the Live server it does not work.
I restart my production server every time I am adding/deleting the class file and .bin files.
