[jboss-jira] [JBoss JIRA] (WFLY-9881) UnsatisfiedLinkError - Open CV

UnsatisfiedLinkError - Open CV -------------------------------- Key: WFLY-9881 URL: https://issues.jboss.org/browse/WFLY-9881 Project: WildFly Issue Type: Bug Components: EJB Affects Versions: 11.0.0.Final Environment: Windows Server 2012 R2 \ Windows 8.1 Professional, 64 bit JRE\JDK 8 update 112 OpenCV 3.3.0 (https://github.com/opencv/opencv/releases/tag/3.3.0) Reporter: Richard Cannock Assignee: Jason Greene Deploying a simple Stateless session bean with a single get method that has a dependency on OpenCV release 3.3.0 (opencv-330.jar) and it's corresponding 64 bit native library (opencv_java330.dll) from https://github.com/opencv/opencv/releases/tag/3.3.0 results in a UnsatisfiedLinkError: Caused by: java.lang.UnsatisfiedLinkError: org.opencv.core.Mat.n_eye(III)J at org.opencv.core.Mat.n_eye(Native Method) at org.opencv.core.Mat.eye(Mat.java:492) at test.SimpleJMSRestfulWebService.putMessage(SimpleJMSRestfulWebService.java:57) The sample get method is shown below: package test; import javax.ejb.Stateless; import javax.ws.rs.GET; import javax.ws.rs.Path; import org.opencv.core.Core; import org.opencv.core.CvType; import org.opencv.core.Mat; /** * */ @Stateless @Path("/jms") public class SimpleJMSRestfulWebService { /** * Our RESTful webservice */ @GET public String putMessage() { System.loadLibrary(Core.NATIVE_LIBRARY_NAME); Mat mat = Mat.eye(3, 3, CvType.CV_8UC1); System.out.println("mat = " + mat.dump()); return "works"; } } The native library is placed in C:\Windows, which is in the java.library.path system variable. Same code runs without exception in GlassFish Server 4.1 and also within netbeans 8.2 (albeit in a differnet test harness) Using -Djava.library.path VM argumnents using a different path for the native library also causes the same error.in wildfly. Removing the library from C:\Windows causes a different stack trace, which suggests that wildfly is at least partially loading the library: Caused by: java.lang.UnsatisfiedLinkError: no opencv_java330 in java.library.path at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1867) at java.lang.Runtime.loadLibrary0(Runtime.java:870) at java.lang.System.loadLibrary(System.java:1122) Using depends.exe or dependency walker on opencv_java330.dll reports no unsatisfied dependencies for this dll.
