How to call a java class in ColdFusion 11
I am trying to use a java class file named Open_NLP but I am having problems.
This is what I have done so far
& bull; Added class file to C:\ColdFusion11\cfusion\wwwroot\WEB-INF\classes
& Bull; Reloading the CF service
This is how I call it
<cfset myObj = CreateObject("java", "Open_NLP")>
And this is the error that I am getting
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.
Am I calling the class wrong? Do I have to take more steps before I can call the class?

If it is a jar file, it needs to go to the / lib directory of the specific ColdFusion instance. The location depends on your installation type and platform. But it's the same / lib that contains other CF-specific jars - look into your CF Admin settings under "system information" or "options summary" - you will see a long list of jar files that are loaded at startup. In what I am currently looking at (this is a multiple instance of cf 9), it is under instancename / cfusion.ear / cfusion.war / WEB-INF / cfusion / lib /, but on CF 11 it should just be .. / WEB -INF / Lib.
You can also place it anywhere on the server and add it to your path path file by editing the jvm.config file.
After adding to / lib or classpath, you will need to restart ColdFusion. Good luck!
