Exception cplex

Question

I am having this exception:

Exception in thread "main" java.lang.UnsatisfiedLinkError: ilog.concert.cppimpl.concert_wrapJNI.swig_module_init()V
    at ilog.concert.cppimpl.concert_wrapJNI.swig_module_init(Native Method)
    at ilog.concert.cppimpl.concert_wrapJNI.<clinit>(concert_wrapJNI.java:1619)
    at ilog.concert.cppimpl.concert_wrap.setDebugWrappers(concert_wrap.java:18)
    at ilog.opl.IloOplFactory.setDebugMode(IloOplFactory.java:170)

I am working on windows with this classpath:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER">
        <attributes>
            <attribute name="org.eclipse.jdt.launching.CLASSPATH_ATTR_LIBRARY_PATH_ENTRY" value="C:/IBM/opl/bin/x64_win64"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="src" path="src"/>
    <classpathentry kind="lib" path="C:/IBM/cplex/lib/cplex.jar">
        <attributes>
            <attribute name="org.eclipse.jdt.launching.CLASSPATH_ATTR_LIBRARY_PATH_ENTRY" value="C:/IBM/cplex/bin"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="lib" path="C:/IBM/opl/lib/oplall.jar"/>
    <classpathentry kind="output" path="bin"/>
</classpath>

Thank you for your help

Answer 1

Don't put oplall.jar and cplex.jar onto the classpath simultaneously. That may cause trouble.

Also make sure that path containing the CPLEX dlls is on your java.library.path.
