Trouble with Java Native Libraries

[Craig L Russell]

Hi,




Any ideas? Other things to try?

Thanks,

Craig

Apache Ant version 1.7.0 compiled on August 25 2008

Maven version: 2.0.6

Test set: testsuite.clusterj.FindByPrimaryKeyTest
-------------------------------------------------------------------------------

java.lang.UnsatisfiedLinkError: no ndbj in java.library.path
        at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1753)
        at java.lang.Runtime.loadLibrary0(Runtime.java:822)
        at java.lang.System.loadLibrary(System.java:993)


Here's the failing code:
    /** Create a file from a property name. */
    Properties getProperties(String fileName) {
        String libpath = System.getProperty("java.library.path");
        System.out.println("java.library.path is " + libpath);
        System.loadLibrary("ndbj");
        Properties result = null;

Here's the pom:
<?xml version="1.0" encoding="UTF-8"?>

I've got a problem using java native libraries with mvn. The tests that fail with mvn run with ant.

When I run this:
mvn test

I get this:

Running testsuite.clusterj.QueryAndDisplayTest


I can run the same tests from ant in the same directory:
