JBOSS 7创建客户端通过JNDI调用 EJB

JBOSS 6，7调用通过JNDI查找EJB的方法和JBOSS5不一样。

 

JBOSS 5

 

		Properties props = new Properties();
		props.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");  //jndi factory 
		props.setProperty("java.naming.provider.url", "localhost:1099"); //jndi server url
		props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");	//jndi finding package

		InitialContext ctx = new InitialContext (props);
		DBBeanRemote db = (DBBeanRemote) ctx.lookup("DBBean/remote");

 

 

JBOSS 6，7

EJB invocations from a remote client using JNDI

官方文档https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+client+using+JNDI

 

总结：

 

1. 查找JNDI

 

 

			final Hashtable jndiProperties = new Hashtable();
			jndiProperties.put(Context.URL_PKG_PREFIXES,
					"org.jboss.ejb.client.naming");//让JNDI API知道是由谁来管理我们用来查找JNDI 名字的命名空间的。
			final Context context = new InitialContext(jndiProperties);
			//appName 和 moduleName分别就打包的格式而定
			//如果是.ear就是appName,其它的是moduleName(.jar,.war)
			final String appName = "";
			final String moduleName = "EJBDBTest";
			final String distinctName = "";
			//实现类名
			final String beanName = DB.class.getSimpleName();
			System.out.println(beanName);
			//接口类名
			final String viewClassName = DBRemote.class.getName();
			System.out.println(viewClassName);
			String jndi = "ejb:" + appName + "/" + moduleName + "/"
					+ distinctName + "/" + beanName + "!" + viewClassName;
			System.out.println(jndi);
			DBRemote db = (DBRemote) context.lookup(jndi);

 

 In AS7, for remote access to EJBs, you use the ejb: namespace with the following syntax:

For stateless beans:
ejb:<app-name>/<module-name>/<distinct-name>/<bean-name>!<fully-qualified-classname-of-the-remote-interface>
For stateful beans:
ejb:<app-name>/<module-name>/<distinct-name>/<bean-name>!<fully-qualified-classname-of-the-remote-interface>?stateful

 

2.加入JAR文件

 把jboss-client jar加入到项目，在 JBOSS_HOME/bin/client/jboss-client-7.1.0.Final.jar 目录下.

 

 

3. 创建客户端调环境（告诉客户端应该去哪里，怎么调server的EJB）

在project path 下创建  jboss-ejb-client.properties 

 

 

endpoint.name=client-endpoint
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
 
remote.connections=default  //connection 的名字
 
remote.connection.default.host=xx.xxx.xxx.xx //IP
remote.connection.default.port = xxxx //port
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false

//JBOSS 用户名密码
remote.connection.default.username=appuser   
remote.connection.default.password=apppassword

      或者你可以另外命名这个文件的名字，只要加入系统参数里就好，如下 

       -Djboss.ejb.client.properties.file.path=/home/me/my-client/custom-jboss-ejb-client.properties

 

   你还可以建立不同的连接

   remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false

 
remote.connections=one, two
 
remote.connection.one.host=localhost
remote.connection.one.port=6999
remote.connection.one.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
 
remote.connection.two.host=localhost
remote.connection.two.port=7999
remote.connection.two.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
