尝试在此链接{web}下运行Hello World EJB时出现以下错误EJB Hello World
这是Bean文件：
package hello;
import javax.ejb.Stateless;
@Stateless(mappedName = "TestSessionBean")
public class TestSessionBean implements TestSessionBeanRemote,
TestSessionBeanLocal {
public String hello(String name) {
System.out.println("Hello" + name);
return name;
}
}
本地界面：
package hello;
import javax.ejb.Local;
@Local
public interface TestSessionBeanLocal {
}
远程接口：
package hello;
import javax.ejb.Remote;
@Remote
public interface TestSessionBeanRemote {
}
客户档案：
package hello;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
public class TestClient {
private static String INITIAL_CONTEXT_NAME ="weblogic.jndi.WLInitialContextFactory";
private static String PROVIDER_URL = "t3://localhost:7001";
private static String JNDI_NAME = "TestSesssionBean";
public static void main(String[] args) throws Exception {
Context ctx = getInitialContext();
TestSessionBean testEJB = (TestSessionBean) ctx
.lookup(JNDI_NAME);
System.out.println(testEJB.hello("Amey"));
}
private static Context getInitialContext() throws NamingException {
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, INITIAL_CONTEXT_NAME);
env.put(Context.PROVIDER_URL, PROVIDER_URL);
return new InitialContext(env);
}
}
