Hi all,
I try to access opl model from my java code using eclipes. I run the sample MyJNIsample.java in eclipse first (change queens8 to queens,because queens8 doesn't work). I can run the sample in JCreator correctly. And I run the sample using command line as well. But I can't run it correctly in eclipse. Because I use other tools in my project so I can not switch to JCreator. I got the error as following:

Intiantiating the OPLsolver engine...
Exception in thread "main" java.lang.UnsatisfiedLinkError: no opljni in java.library.path
  at java.lang.ClassLoader.loadLibrary(Unknown Source)
  at java.lang.Runtime.loadLibrary0(Unknown Source)
  at java.lang.System.loadLibrary(Unknown Source)
  at ilog.opl.engine.OPLsolver.<clinit>(OPLsolver.java:7)
  at MyJNIsample.run(MyJNIsample.java:47)
  at MyJNIsample.main(MyJNIsample.java:81)

I have spend several days on it. But I can not solve this problem.
Can someone give me some advice? I will appreciate any of your help!

Hello there,
Is it a correct observation that you use OPL3.71 and 1.6JDK? If I remember well 3.71 was in the era of 1.4JDK so I suspect that this JDK mismatch is the problem...

It seems not because of JDK 1.6. Today, I run the code in NetBeans, it does work. The default JDK for NetBeans on my computer is JDK 1.6.
But I really don't know why I can not run it correctly in eclipse. Fortunately, I can use NetBean to continue my work now.
