While the following TestNG test works fine with the mode RunModeType.AS_CLIENT:

@Run(RunModeType.AS_CLIENT)
public class FooServiceTest extends Arquillian {

    private static final Logger log = Logger.getLogger(FooServiceTest.class.getName());

    @Deployment
    public static EnterpriseArchive createDeployment() throws IOException {
        final JavaArchive ejbJar = ShrinkWrap.create(JavaArchive.class, "ejb.jar").addClasses(FooService.class,
                FooServiceBean.class);
        final WebArchive war = ShrinkWrap.create(WebArchive.class, "foo.war").addClasses(EJBBean.class,
                EJBInterceptor.class, BaseActionBean.class, FooActionBean.class).addLibraries("stripes-1.5.3.jar")
                .setWebXML("WEB-INF/web.xml"); // Find a better way to inject dependencies
        final EnterpriseArchive ear = ShrinkWrap.create(EnterpriseArchive.class, "stripes-ejb3.ear").addModule(ejbJar)
                .addModule(war);
        log.info(ear.toString(true));

        return ear;
    }

    @Test
    public void shouldGreetUser() throws IOException {
        final String name = "Earthlings";
        final URL url = new URL("http://localhost:8080/foo/Foo.action");
        StringBuilder builder = new StringBuilder();
        BufferedReader reader = new BufferedReader(new InputStreamReader(url.openStream()));
        String line;

        while ((line = reader.readLine()) != null) {
            builder.append(line);
        }
        reader.close();

        log.info("Returned response:");
        log.info(builder.toString());
        assertEquals(builder.toString(), FooService.GREETING + name);
    }
}

It fails with the default mode RunModeType.IN_CONTAINER.

Doing the following request

127.0.0.1 - - [11/Oct/2010:02:10:06 +0100] "GET /test/ArquillianServletRunner?outputMode=serializedObject&className=my.package.FooServiceTest&methodName=shouldGreetUser HTTP/1.1" 200 2971

instead of

127.0.0.1 - - [11/Oct/2010:02:33:35 +0100] "GET /foo/Foo.action HTTP/1.1" 200 17

Does anyone knows why this happens?

Cheers,

Samuel
