首先建一个java工程：
EJB接口:
package cn.service;
public interface ServiceTest {
public String sayHello();
}
EJB实现类：
package cn.service.imp;
import javax.ejb.Remote;
import javax.ejb.Stateless;
import cn.service.ServiceTest;
@Stateless
@Remote(ServiceTest.class)
public class ServiceImpTest implements ServiceTest {
public String sayHello() {
return "Hello World";
}
}
JNDI:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=localhost:1099
再次：建一个web,导入部置的ejb jar包测试：
<center>
<form action="TestServlet">
<input type="submit" value="submit">
</form>
</center>
servlet代码：
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
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");
InitialContext ctx = null;
try {
ctx = new InitialContext();
ServiceTest st = (ServiceTest) ctx.lookup("ServiceImpTest/remote");
System.out.println(st.sayHello());
} catch (NamingException e) {
e.printStackTrace();
}
}
报如果下错误，请各位帮看一下：

------解决方案--------------------------------------------------------
关键是这一句。
Name ServiceImpTest is not bound in this Context
没有绑定到上下文中。

EJB没有发布？
