please help me I need to be hurry for this project.
The error suggests that you have not called com.secneo.sdk.Helper.install(context).
This is usually done in an override of Application class. You also need to indicate the new application class override in the manifest.
Look at the sample app:
<application
android:name=".internal.controller.DJISampleApplication"
and in the Application override:
public class DJISampleApplication extends MultiDexApplication {
protected void attachBaseContext(Context paramContext) {
super.attachBaseContext(paramContext);
MultiDex.install(this);
com.secneo.sdk.Helper.install(this);
app = this;
}

In a simple app that I run on Open Liberty 21.0.0.8, I have provided an implementation of HttpAuthenticationMechanism:
// imports omitted
#CustomFormAuthenticationMechanismDefinition(
loginToContinue = #LoginToContinue(
loginPage = "/login.xhtml",
errorPage = "",
useForwardToLogin = false))
#ApplicationScoped
public class CustomAuthenticationMechanism implements HttpAuthenticationMechanism {
#Inject
private IdentityStoreHandler identityStoreHandler;
#Override
public AuthenticationStatus validateRequest(HttpServletRequest request,
HttpServletResponse response,
HttpMessageContext context) throws AuthenticationException {
Credential credential = context.getAuthParameters().getCredential();
if (credential != null) {
return context.notifyContainerAboutLogin(identityStoreHandler.validate(credential));
}
else {
return context.doNothing();
}
}
}
I expected Open Liberty to place that implementation of HttpAuthenticationMechanism into service.
However, on startup of Open Liberty a javax.enterprise.inject.spi.DeploymentException is thrown:
[INFO] [ERROR ] CWWKS1925E: The deployment for the dsgvo-management.war module in the dsgvo-management application failed because of multiple HttpAuthenticationMechanism implementations: de.knusperfisch.dsgvo.app.security.control.CustomAuthenticationMechanism, com.ibm.ws.security.javaeesec.cdi.beans.CustomFormAuthenticationMechanism. This failure is likely an application packaging issue. Make sure that each module has only one HttpAuthenticationMechanism implementation.
[INFO] [ERROR ] CWWKZ0004E: An exception occurred while starting the application dsgvo-management. The exception message was: com.ibm.ws.container.service.state.StateChangeException: org.jboss.weld.exceptions.DefinitionException: Exception List with 1 exceptions:

[INFO] at com.ibm.ws.security.javaeesec.cdi.extensions.JavaEESecCDIExtension.afterBeanDiscovery(JavaEESecCDIExtension.java:173)
The Java EE Security API states that:
An application MAY supply its own HttpAuthenticationMechanism, if desired.
and:
An HttpAuthenticationMechanism must be a CDI bean, and is therefore
visible to the container through CDI if it is packaged in a bean
archive, which generally include Java EE modules and application
archives [...]
It MUST be possible for the definition of an
HttpAuthenticationMechanism to exist within the application archive
[...]
Is there a way in Open Liberty to configure a specific HttpAuthenticationMechanism for an app from an application archive, and if so, how is this done?
At first glance, as the error message indicates, looks like there are multiple HttpAuthMechanisms active which is not allowed. Are there are any apps that are using the #CustomFormAuthenticationMechanismDefinition annotation which would bring in the default com.ibm.ws.security.javaeesec.cdi.beans.CustomFormAuthenticationMechanism AuthMech in addition to your CustomAuthenticationMechanism ?
The code is very simple, just open a picture.
But when I run this I have an error like this:
Exception in thread "main" java.lang.UnsatisfiedLinkError: org.opencv.imgcodecs.Imgcodecs.imread_1(Ljava/lang/String;)J

According to the searched solution, I add this System.load(Core.NATIVE_LIBRARY_NAME) to the main(), doesn't work:

Or this System.loadLibrary(Core.NATIVE_LIBRARY_NAME), still not work:

My project is build by gradle, the dependencies is (official doc):
compile group: 'org.bytedeco', name: 'javacv-platform', version: '1.5'
Thank you for your help.
Self answer.
My import is wrong. It should be
import static org.bytedeco.opencv.global.opencv_imgcodecs.imread
instead of
import static org.opencv.imgcodecs.Imgcodecs.imread
This error caused the wrong package to be used.
The correct code is:
import org.bytedeco.opencv.opencv_core.Mat;
import static org.bytedeco.opencv.global.opencv_imgcodecs.imread;
public class DemoApplication {
public static void main(String[] args) {
Mat image = imread("/root/test.png");
System.out.println("width：" + image.cols());
System.out.println("height：" + image.rows());
}
}
I'm trying to run Arquillian tests on a Wildfly managed container.
Here's the Arquillian's deployment and the test:
#RunWith(Arquillian.class)
public abstract class ArquillianTestCase {
#Deployment
public static WebArchive createDeployment() {
/* Create the war file according to build.gradle. */
WebArchive war = ShrinkWrap.create(EmbeddedGradleImporter.class)
.forThisProjectDirectory().importBuildOutput()
.as(WebArchive.class);
/* Add the abstract test classes to war. */
war.addClasses(ArquillianTestCase.class, SeleniumTestCase.class);
/* Add selenium and its transitive dependencies to war's lib. */
String seleniumJava = "org.seleniumhq.selenium:selenium-java:3.3.1";
MavenResolverSystem resolver = Maven.resolver();
File[] seleniumFiles = resolver.resolve(seleniumJava).withTransitivity()
.asFile();
war.addAsLibraries(seleniumFiles);
return war;
}
}
public class LoginTest extends ArquillianTestCase {
#Test
public void shouldRun() throws Exception {
System.out.println("LoginTest!");
Assert.assertTrue(true);
}
}
I don't have any arquillian.xml file, so I rely on JBOSS_HOME environment variable to let Arquillian find my Wildfly:
echo $JBOSS_HOME
/opt/wildfly-8.2.1.Final
All of this process is started by a Gradle build, so here are the most relevant dependencies of my build.gradle file:
dependencies {
/* Arquillian for managing the life cycle of the container. */
testCompile 'org.jboss.arquillian.junit:arquillian-junit-container:1.1.10.Final'
/* Arquillian and Wildfly integration. */
testCompile 'org.wildfly:wildfly-arquillian-container-managed:8.2.1.Final'
/* Arquillian and Gradle integration. */
testCompile 'org.jboss.shrinkwrap.resolver:shrinkwrap-resolver-gradle-depchain:2.2.6'
/* Arquillian and Maven integration for resolving dependencies at runtime. */
testCompile 'org.jboss.shrinkwrap.resolver:shrinkwrap-resolver-api-maven:2.2.6'
testCompile 'org.jboss.shrinkwrap.resolver:shrinkwrap-resolver-impl-maven:2.2.6'
/* Selenium for front-end testing. */
testCompile 'org.seleniumhq.selenium:selenium-java:3.3.1'
}
If I run this setup on Windows with my JBOSS_HOME pointing to a valid Wildfly installation, it works fine, but when I reproduce the same setup on Ubuntu Server 14.04, I get the error below:
org.jboss.arquillian.container.spi.client.container.LifecycleException: Could not start container

... 84 more
I tried to reproduce this behavior on Windows and realised that it happens when I remove my environment variable JBOSS_HOME, so Arquillian doesn't find my container, but back on Ubuntu, even that variable exists, it doesn't work.
Any ideas? Thanks in advance.
I want to record video quiet and without preview in Android. So I choice MediaRecorder but I could record only without preview but what make me crazy is that when MediaRecorder start or stop it will with a sound dee.... I try many methods about that . But I think it perhaps sth related to the OS of the mobile. So I try JavaCV because I also want to have a Live function in my app.
But JavaCV spent me to too much time to solve some strange problems because it's my first time to do sth about C++ src and video.

So I want to know a comfortable method to achieve my goal : recode video quiet and without preview. And Live real time ?
I found ffmpeg4android is a prefect library to run ffmpeg command. I just use it to compress videos from MediaRecorder But I don't how to do use it to achieve my goal.
I'm trying to run simple Spring Data Rest Boot app (v1.2.3.RELEASE) with only one small modification from working Spring reference example app (http://spring.io/guides/gs/accessing-mongodb-data-rest/) and it failed to start.
To be more specific when I use:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-rest</artifactId>
</dependency>
and just following simple code configuration:
public class Application {
public static void main(String[] args){
SpringApplication.run(Config.class, args);
}
}
#SpringBootApplication
public class Config {
}
without anything else I'm getting following error on startup:
2015-04-20 12:07:32.250 ERROR 5693 --- [ main]
o.s.boot.SpringApplication : Application startup failed
org.springframework.context.ApplicationContextException: Unable to

at
org.springframework.boot.autoconfigure.data.rest.SpringBootRepositoryRestMvcConfiguration$$EnhancerBySpringCGLIB$$3a999d99.config()
...
However following code configuration is working fine:
#SpringBootApplication
public class Application {
public static void main(String[] args){
SpringApplication.run(Application.class, args);
}
}
Also if instead I use:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
separate Java config class approach is working fine as well...
What I'm doing wrong, cause I can't believe I spotted such an obvious bug?
Thank you,
Oleg
The problem appears to be due to a name clash between the config bean method on SpringBootRepositoryRestMvcConfiguration (inherited from Spring Data REST's RepositoryRestMvcConfiguration) and your configuration class named Config. Renaming it to something other than Config should get things working again.
