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.
My issue was the versions of windows. On development we are using Windows server 2008 R2 and on production we were using Windows server 2008 SP2, which based on what I read online they have a lot differences (minor but important) We updated our production server on Friday and everything started working. Thanks to all that replied to this post.
