GlassFish - UnsatisfiedLinkError: no jniopencv_core in java.library.path

[Marcelo]

Hi...

I developed a face detect application in GUI (it is work fine) and now
I'm trying to develop a services to consume this.
My current server is the "GlassFish Server 3.1" and the following
error occurs when the services is used:

At runtime JavaCV/JavaCPP can behave just like JNI, so simply do
whatever you need to do with .dll/.so/.dylib files and it should work..
These containers usually need us to do something special in the case of JNI.

This happens because the orignal class loader (that you did the tests) was changed by the glassfish container.
In tomcat service I've got the same error. To fix it, be sure the opencv is in classpath, and If not work, try to put the opencv DLL in the glassfish bin.

Hi,

I am using Netbeans 8.2 with GlassFish 4.1.1. I have started working on javaCV face recognition but getting below error. Please refer the attached screenshot for Library used with sample code.
