【问题描述】：
我正在尝试连接到部署在 JBoss 7 服务器中的远程 EJB。我试图通过查看从 JBoss CLI 获得的 JNDI 转储来弄清楚 JNDI 名称是什么。
无论我尝试什么，我都无法查找 EJB。
我认为jndi名称应该是：java:global/XNet/api/ReceivingAPI_EJB!com.mycompany.receiving.api.ReceivingAPI_EJBRemote
这是我正在使用的客户端：
package com.mycompany.mavenproject1;
import com.mycompany.receiving.api.ReceivingAPI_EJBRemote;
import com.mycompany.receiving.api.ReceivingAPI;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import java.util.Properties;
/**
* Hello world!
*
*/
public class App
{
public static void main( String[] args ) throws NamingException
{
System.out.println( "Hello World!" );
//ReceivingAPI ejbRemote = DomainHelper.getHQApi(com.mycompany.receiving.api.ReceivingAPI.class);
ReceivingAPI_EJBRemote ejbRemote = App.lookupRemoteStatelessCalculator();
ejbRemote.getOpenRcvdocForSite(null, 7);
}
// private static ReceivingAPI_EJBRemote lookupRemoteStatelessReceiving() throws NamingException {
//
// }
//
private static ReceivingAPI_EJBRemote lookupRemoteStatelessCalculator() throws NamingException {
final Properties jndiProperties = new Properties();
jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
jndiProperties.put(Context.PROVIDER_URL,"remote://someserver.xmx.com:1199");
// username
jndiProperties.put(Context.SECURITY_PRINCIPAL, "mycompany1");
// password
jndiProperties.put(Context.SECURITY_CREDENTIALS, "<removed>");
//final Context context = new InitialContext(jndiProperties);
jndiProperties.put("jboss.naming.client.ejb.context", true);
InitialContext context = new InitialContext( jndiProperties );
// The app name is the application name of the deployed EJBs. This is typically the ear name
// without the .ear suffix. However, the application name could be overridden in the application.xml of the
// EJB deployment on the server.
// Since we haven't deployed the application as a .ear, the app name for us will be an empty string
final String appName = "XNet";
// This is the module name of the deployed EJBs on the server. This is typically the jar name of the
// EJB deployment, without the .jar suffix, but can be overridden via the ejb-jar.xml
// In this example, we have deployed the EJBs in a jboss-as-ejb-remote-app.jar, so the module name is
// jboss-as-ejb-remote-app
final String moduleName = "api";
// AS7 allows each deployment to have an (optional) distinct name. We haven't specified a distinct name for
// our EJB deployment, so this is an empty string
final String distinctName = "hq";
// The EJB name which by default is the simple class name of the bean implementation class
final String beanName = com.mycompany.receiving.api.ReceivingAPI.class.getSimpleName();
// the remote view fully qualified class name
final String viewClassName = ReceivingAPI_EJBRemote.class.getName();
// let's do the lookup
try {
ReceivingAPI test1 = (ReceivingAPI)context.lookup("java:global/XNet/api/" + beanName + "_EJB!" + viewClassName);
System.out.println("Test1 = " + test1.getClass().getName());
} catch(Throwable t) {
System.out.println(t);
}
try {
ReceivingAPI test = (ReceivingAPI)context.lookup("java:global/XNet/api/hq/" + beanName + "_EJB!com.mycompany.receiving.api.ReceivingAPI_EJBRemote");
System.out.println("Test = " + test.getClass().getName());
} catch(Throwable t) {
System.out.println(t);
}
try {
ReceivingAPI test = (ReceivingAPI)context.lookup("ejb:XNet/api/hq/" + beanName + "_EJB!com.mycompany.receiving.api.ReceivingAPI_EJBRemote");
System.out.println("Test = " + test.getClass().getName());
} catch(Throwable t) {
System.out.println(t);
}
return (ReceivingAPI_EJBRemote) context.lookup("ejb:" + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "_EJB!" + viewClassName);
}
}
上一个java类的运行输出：
Hello World!
javax.naming.NameNotFoundException: global/XNet/api/ReceivingAPI_EJB!com.mycompany.receiving.api.ReceivingAPI_EJBRemote -- service jboss.naming.context.java.jboss.exported.global.XNet.api."ReceivingAPI_EJB!com.mycompany.receiving.api.ReceivingAPI_EJBRemote"
javax.naming.NameNotFoundException: global/XNet/api/hq/ReceivingAPI_EJB!com.mycompany.receiving.api.ReceivingAPI_EJBRemote -- service jboss.naming.context.java.jboss.exported.global.XNet.api.hq."ReceivingAPI_EJB!com.mycompany.receiving.api.ReceivingAPI_EJBRemote"

这是 JNDI CLI 命令的转储：
[jboss1@hmudev01 bin]$ ./jboss-cli.sh --connect controller=localhost:10099
[standalone@localhost:10099 /] /subsystem=naming:jndi-view
{
"outcome" => "success",
"result" => {
"java: contexts" => {
"java:global" => {
"XNet" => {
"class-name" => "javax.naming.Context",
"children" => {
"api" => {
"class-name" => "javax.naming.Context",
"children" => {
"ReceivingAPI_EJB!com.mycompany.receiving.api.ReceivingAPI_EJBLocal" => {
"class-name" => "com.mycompany.receiving.api.ReceivingAPI_EJBLocal$$$view46",
"value" => "Proxy for view class: com.mycompany.receiving.api.ReceivingAPI_EJBLocal of EJB: ReceivingAPI_EJB"
},
"ReceivingAPI_EJB!com.mycompany.receiving.api.ReceivingAPI_EJBRemote" => {
"class-name" => "com.sun.proxy.$Proxy272",
"value" => "Proxy for remote EJB StatelessEJBLocator{appName='XNet', moduleName='api', distinctName='hq', beanName='ReceivingAPI_EJB', view='interface com.mycompany.receiving.api.ReceivingAPI_EJBRemote'}"
},
}
}
}
}
}
}
...
}
}
[standalone@localhost:10099 /]
我的任何 maven 部门如下：
<dependencies>
<dependency>
<groupId>com.mycompany.receiving</groupId>
<artifactId>xnet-domain-receiving-client</artifactId>
<version>2.5.0-SNAPSHOT</version>
</dependency>

【问题讨论】：
-
对于远程查找，我认为您可以取消与
global相关的任何内容，因为您所追求的将是ejb:。话虽如此，我认为您的查找字符串有点时髦。它应该类似于ejb:<app_name>/<bean_name>!<bean_interface>。如果您部署在.ear中，这将略有变化 -
所以在你的情况下，我认为（假设 RNet 是你的 .jar 的名称）你所追求的字符串是
ejb:RNet/ReceivingAPI_EJB!com.mycompany.receiving.api.ReceivingAPI_EJBLocal（注意缺少 java:ejb）。假设这是故意的，您似乎也在将一些非标准端口推入您的 jndi 设置中。如果这不起作用，可能想看看 jndiProps 接下来。 -
Rhys 你大部分是对的，但它让我有能力弄清楚我需要做什么。我会在答案中发布。
