EJBCLIENT000409：没有更多目的地可用

Question

我正在从jboss 5迁移到wildfly 12.我陷入了我的一个例外我正在使用wildfly 12和jndi在java 8中进行ejb（3.1）调用我已经在wildfly控制台上部署了.ear文件之后我得到了这个例外。我正在使用java ee 5。

这是一个Wildfly 12服务器，java 8.我尝试过更改jndi属性。

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);

我期望迁移的输出和成功运行项目，但实际输出是

Answer 1

您的初始上下文工厂可能是错误的，您没有显示该值，但该常量的名称暗示仍然是唯一的jnp协议

Answer 2

当您使用org.jboss.ejb.client.naming时，连接通常在名为jboss-ejb-client.properties的文件中定义。你在地图上为jndi.properties提供了它。 jboss-ejb-client.properties看起来像这样：

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

如果这样可行，但您不想将文件用于连接属性，则可以查看https://developer.jboss.org/thread/202008

Answer 3

可能问题不在于InitialContext配置，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");

格式是：

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