关于EJB的调用（在线等，急啊！！！！）

[gongqh21]

在普通java类中调用ejb时，出现下面异常：

Exception in thread "main" java.lang.reflect.UndeclaredThrowableException
at $Proxy0.hello(Unknown Source)
at Client.main(Client.java:20)
Caused by: java.lang.Exception: Can not make remoting client invocation due to not being connected to server.

客户短测试代码：
public class Client {
public static void main(String args[]) {
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 ctx = new InitialContext(props);
Hello helloworld = (Hello) ctx.lookup("HelloBean/remote");
System.out.println(helloworld.hello());
} catch (NamingException e) {
e.printStackTrace();
}
}
}

不能连接到服务器。感觉你的props里的属性写的有问题！

在JBOSS里查看是否有这个EJB

[piaopiao11]

props.setProperty("java.naming.provider.url", "jnp://localhost:1099");
前面还有个jnp把

[felix_2007]

Properties props = new Properties();
//设置属性，用来连接jndi服务器，得到对象的远程对象
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");
InitialContext ctx;
try {
ctx = new InitialContext(props);
//根据jndi名字查找，得到对应的远程对象，这个远程对象是Hello的子类的对象
Hello hello = (Hello) ctx.lookup("HelloBean/remote");
//调用远程方法。得到结果
System.out.println(hello.getHello(“aaa"));
} catch (NamingException e) {
e.printStackTrace();
}


这都是些基本固定的代码啊！
谁还会写错啊！
检查配置文件咯
