我正在执行从jboss 5到wildfly 12的迁移。我遇到了一个异常。我正在使用带有java 8中的jndi的wildfly 12执行ejb（3. 1）调用。我已经在wildfly控制台上部署了.ear文件。之后，我遇到了这个异常。我使用的是java ee 5。
这是一个Wildfly 12服务器，java 8。我已经尝试了jndi属性的更改。

private final Properties config;

config = new Properties();

config.put(Context.INITIAL_CONTEXT_FACTORY, JNP_NAMING_CONTEXT_FACTORY);
config.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
config.put(Context.PROVIDER_URL, "http-remoting://127.0.0.1:8080/");
//config.put(Context.PROVIDER_URL,"remote+http://127.0.0.1:8080");
config.put("jboss.naming.client.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT", "false");

config.put("jboss.naming.client.ejb.context", "true"); 
config.put(Context.SECURITY_PRINCIPAL, "wixxxxxx");
config.put(Context.SECURITY_CREDENTIALS, "xxxxxx123");

Context ctx = new InitialContext(config);

我期望迁移和成功运行项目的输出，但实际输出是

你的初始上下文工厂可能是错误的，你没有显示它的值，但是这个常量的名称仍然是唯一的jnp协议

使用org.jboss.ejb.client.naming时，连接通常在名为jboss-ejb-client.properties的文件中定义。您在jndi.properties的Map中提供了该连接。jboss-ejb-client.properties如下所示：

remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
remote.connections=default
remote.connection.default.host=localhost
remote.connection.default.port = 8080
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
remote.connection.two.host=localhost
remote.connection.two.port = 8080
remote.connection.two.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false

如果这样做有效，但是您不想使用connection-properties文件，那么可以查看https://developer.jboss.org/thread/202008

问题可能不是InitialContext配置，它看起来是正确的。
尝试使用以下格式进行查找：

ctx.lookup("ejb:EJBWildFly-1.0-SNAPSHOT/TextProcessorBean!com.gct.interfaces.TextProcessorRemote");

格式为：

context.lookup("ejb:" + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + viewClassName);

有关详细信息，请查看此文档示例：https://docs.jboss.org/author/display/WFLY8/EJB+invocations+from+a+remote+client+using+JNDI
