    <p>I have a java class (eval.java) that invokes a native method in an so file (libmodel.so). I can use System.loadLibrary() to load the libmodel.so without any error (-Djava.library.path=/usr/lib), and the native method initModel() works fine.</p> <p>However, when I deploy it as a web service (tomcat 6.0.26 + axis2 1.5.1 + eclipse Java EE helios) to call the native method, I got the following error (the first line means the .so was successfully loaded):</p> <pre> Load library successfully [ERROR] com.model.modelJNI.initModel()V java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.axis2.rpc.receivers.RPCUtil.invokeServiceClass(RPCUtil.java:194) at org.apache.axis2.rpc.receivers.RPCMessageReceiver.invokeBusinessLogic(RPCMessageReceiver.java:102) at org.apache.axis2.receivers.AbstractInOutMessageReceiver.invokeBusinessLogic(AbstractInOutMessageReceiver.java:40) at org.apache.axis2.receivers.AbstractMessageReceiver.receive(AbstractMessageReceiver.java:114) at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:173) at org.apache.axis2.transport.http.HTTPTransportUtils.processHTTPPostRequest(HTTPTransportUtils.java:167) at org.apache.axis2.transport.http.AxisServlet.doPost(AxisServlet.java:142) at javax.servlet.http.HttpServlet.service(HttpServlet.java:637) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Thread.java:619) Caused by: java.lang.UnsatisfiedLinkError: com.model.modelJNI.initModel()V at com.model.modelJNI.initModel(Native Method) at com.model.model.initModel(model.java:13) at com.webservice.run(EvalVita.java:763) ... 25 more </pre> <p>Below is the body of Eval.java</p> <pre><code>import com.model.*; public class Eval { static void loadModel() { try { System.loadLibrary("model"); System.out.println("Load library successfully"); } catch (UnsatisfiedLinkError e) { System.err.println("Native code library failed to load." + e); } } public void run() { loadModel(); model.initModel(); } } </code></pre> <p>Am I missing anything here?

    1. COHave you definitely specified the same java.library.path when running under Tomcat?

    2. COYes, Tomcat does has the library path. /usr/java/jdk1.6.0_01/jre/lib/i386/server: /usr/java/jdk1.6.0_01/jre/lib/i386: /usr/java/jdk1.6.0_01/jre/../lib/i386: /usr/lib/xulrunner-1.9: /usr/java/packages/lib/i386: /lib: /usr/lib

    3. COI assume this is tomcat classpath, but do you pass -Djava.library.path=/usr/lib argument to JVM you are running tomcat on?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
