环境
jboss jboss7.1.1
所使用的包 有 jboss/bin/client/jboss-client.jar
还有从网上找的jnpserver.jar
代码不部分很简单
HelloWorld 接口
- Java code
public interface HelloWorld { public String SayHello(String name); }HelloWorldBean
- Java code
import com.jav.impl.HelloWorld; import javax.ejb.Remote; import javax.ejb.Stateless; @Stateless @Remote(HelloWorld.class) public class HelloWorldBean implements HelloWorld { @Override public String SayHello(String name) { // TODO Auto-generated method stub return name+"Welcome Test"; } } Test代码
- Java code
Properties props=new Properties(); props.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory"); props.setProperty("java.naming.provider.url","localhost:1099"); props.setProperty("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces"); try { InitialContext context=new InitialContext(props); HelloWorld hello=(HelloWorld)context.lookup("HelloWorldBean/remote"); System.out.println(hello.SayHello("Hello Kitty")); } catch(NamingException e) { e.printStackTrace(); System.out.println(e.getMessage()); } 部署上面的HelloWorld 和HelloWorldBean 的jar包之后
java:global/Hello/HelloWorldBean！com.jav.impl.HelloWorld
java:app/Hello/HelloWorldBean！com.jav.impl.HelloWorld
java:module/Hello/HelloWorldBean！com.jav.impl.HelloWorld
java:jboss/exported/Hello/HelloWorldBean！com.jav.impl.HelloWorld
java:global/Hello/HellWorldBean
java:app/Hello/HellWorldBean
java:module/Hello/HellWorldBean
启动之后出现上面的代码
但是我Test类做测试的时候还是报出异常，但是我用jboss-6.1.0.Final 做测试的同样的代码没有错误，问题应该还是在jboss7上
错误时
javax.naming.CommunicationException: Could not obtain connection to any of these urls: localhost:1099 and discovery failed with error: javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out] [Root exception is javax.naming.CommunicationException: Failed to connect to server localhost:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server localhost:1099 [Root exception is java.net.ConnectException: Connection refused: connect]]]
