名称 [ejb:..] 未绑定在此上下文中。无法在 Wildfly 中找到具有根本原因 javax.naming.NameNotFoundException 的 [ejb: ].]
Name [ejb:..] is not bound in this Context. Unable to find [ejb: ].] with root cause javax.naming.NameNotFoundException in Wildfly
我正在尝试在远程环境中调用我的 EJB，并且我正在使用 Wildfly 作为我的容器。
抱歉，这是我第一次尝试以远程方式调用 EJB。
我已经使用下面的说明在 Wildfly 中调用 EJB。
https://docs.jboss.org/author/display/WFLY8/EJB+invocations+from+a+remote+client+using+JNDI
但是，我调用这些 EJB 时出错，我不知道我的配置有什么问题。

我在远程服务器端和客户端的界面：
public interface ImageManipulateService{
public UploadedImage manipulate(UploadedImage img) throws IOException, Exception;
}
我在远程服务器（Wildfly）中的 EJB：
@Service
@Stateless
@Remote(ImageManipulateService.class)
public class GrayscaleImageServiceImpl implements ImageManipulateService{
@Override
public Object manipulate(Object img) throws IOException, Exception {
....
}
}
客户端：
jboss-ejb-client.properties
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
remote.connections=default
remote.connection.default.host = localhost
remote.connection.default.port = 9090
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
我一直是 运行 我在 tomcat 服务器 (:8080) 中的客户端，我正在尝试通过 localhost:9090 在 Wildfly 上调用 EJB。 （正确吗？）
I also have the jboss-client.jar included in my Maven dependencies. I
used version 4.0.2. (jboss-client-4.0.2.jar)
我制作了一个java class 来调用服务查找，以便于调用它们。
public class RemoteContext {
public static ImageManipulateService lookupRemoteGrayscaleService() throws NamingException {
Hashtable jndiProperties = new Hashtable();
jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
Context context = new InitialContext(jndiProperties);
String appName = "";
String moduleName = "ImageService-1.0-SNAPSHOT";
String distinctName = "";
String beanName = "GrayscaleImageServiceImpl";
String viewClassName = "com.project.imageservice.ImageManipulateService";
return (ImageManipulateService) context.lookup("ejb: " + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + viewClassName);
}
public static ImageManipulateService lookupRemoteTimestampService() throws NamingException {
Hashtable jndiProperties = new Hashtable();
jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
Context context = new InitialContext(jndiProperties);
String appName = "";
String moduleName = "ImageService-1.0-SNAPSHOT";
String distinctName = "";
String beanName = "TimestampImageServiceImpl";
String viewClassName = "com.project.imageservice.ImageManipulateService";
return (ImageManipulateService) context.lookup("ejb: " + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + viewClassName);
}
}
如果你的EJB部署在war，那么JNDI名称中的应用程序名称应该是空。尽管您的 appName 变量包含一个空字符串，但您在 "ejb:" 之后有一个 space 字符。删除此 space，使其与文档中的一样：
ejb:/jboss-as-ejb-remote-app//CalculatorBean!org.jboss.as.quickstarts.ejb.remote.stateless.RemoteCalculator
你这里的主要问题是你用错了jboss-client.jar。您选择的是用于 JBoss 4.0.x 并且根本不适用于 WildFly。
如果您使用 Maven 进行构建，那么您将在客户端应用程序（即 war 项目）中包含以下依赖项：
<dependency>
<groupId>org.wildfly</groupId>
<artifactId>wildfly-ejb-client-bom</artifactId>
<version>10.1.0.Final</version>
<type>pom</type>
</dependency>
但是由于您似乎没有使用 Maven，替代方法是添加 jboss-client.jar，您可以在 WildFly 安装的 bin/client/ 目录中找到它。这是一个 "uber-jar" 包含上面显示的 Maven 依赖项定义的所有内容。
一旦你解决了这个问题，你可能需要一些关于 JNDI 名称的帮助。我们将能够通过您的 server.log 的部署输出来解决这个问题，它记录了您所有的 EJB 应用程序的 JNDI 名称。
我正在尝试在远程环境中调用我的 EJB，并且我正在使用 Wildfly 作为我的容器。
抱歉，这是我第一次尝试以远程方式调用 EJB。
我已经使用下面的说明在 Wildfly 中调用 EJB。 https://docs.jboss.org/author/display/WFLY8/EJB+invocations+from+a+remote+client+using+JNDI
