I am trying to use a java class file called Open_NLP but I am running into issues.

This is what I did so far

• Added the class file in C:\ColdFusion11\cfusion\wwwroot\WEB-INF\classes
• Restarted the CF service

This is how I am calling it

<cfset myObj = CreateObject("java", "Open_NLP")>

And this is the Error 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 am able to call the class?

    Why are you using WEB-INF\classes? That is typically for individual .class files only. For jar files, use WEB-INF\lib. Can you post the stack trace message? Commented Jan 6, 2015 at 23:14

    After you move the OpenNLP jars to ..\lib and restart, do you still get the error above? Also, from the piece of the error message we can see, it looks a lot like the error in your previous thread about CF9 - any relevance? Commented Jan 7, 2015 at 3:37
  • By the way did you already read the article - 'Creating and using a simple Java class' from adobe help.adobe.com/en_US/ColdFusion/9.0/Developing/… It might be helpful. Commented Jan 7, 2015 at 5:24
  • @Leigh my previous thread was when the other developer was working on it and I posted the article for him. That time we got it to work by accident to be honest and it was in a totally different folder. I am only using a single class file that's why I added it under classes. I will need to search more to see if there are any more files associated with this task. Will get back to you soon Commented Jan 7, 2015 at 15:15

    (Edit) It is a missing a class. See Caused by: java.lang.ClassNotFoundException: opennlp.tools.util.ObjectStream... Why do you think only a single class file is involved? Perhaps you are using some custom class built on top of the OpenNLP project linked above? If so, it is not just a single class. It is dependent on the OpenNLP jars too. So you need put those jars in the WEB-INF\lib folder and restart. Commented Jan 7, 2015 at 15:53

If this is a jar file it needs to go into the /lib directory of the specific ColdFusion instance. The location depends on your type of installation and platform. But it's the same /lib that contains other CF specific jars - look in your CF Admin settings under "system information" or "settings summary" - you will see a long list of jar files that are being loaded upon start. In the one I'm currently looking at (which is a multi-instance cf 9) it is under instancename/cfusion.ear/cfusion.war/WEB-INF/cfusion/lib/ but on CF 11 it should be just ../WEB-INF/lib.

You can also put it anywhere on the server and add th location to the class path file by editing the jvm.config file.

After adding it to /lib or to the classpath you will need to restart ColdFusion. Good luck!
