jb7、weblogic环境下开发实体bean遇到jndi问题？

ltz 2003-03-20 04:59:33

CustomersBean 实体bean
CustomersRemoteHome 本地接口
CustomersRemote 远程接口（jndi名称：MyCustomersRemote）
启动服务器，发布ejb后，
运行测试程序：
public class CustomersTestClient
{
private CustomersRemoteHome customersRemoteHome = null;

//Construct the EJB test client
public CustomersTestClient()
{
try
{
//get naming context
Context ctx = getInitialContext();

//look up jndi name
Object ref = ctx.lookup("MyCustomersRemote");

//cast to Home interface
customersRemoteHome = (CustomersRemoteHome) PortableRemoteObject.narrow(ref, CustomersRemoteHome.class);
}
catch(Exception e)
{
e.printStackTrace();
}
}

private Context getInitialContext() throws Exception
{
String url = "t3://beelink-weihai:7001";
String user = null;
String password = null;
Properties properties = null;
try
{
properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
properties.put(Context.PROVIDER_URL, url);
if (user != null)
{
properties.put(Context.SECURITY_PRINCIPAL, user);
properties.put(Context.SECURITY_CREDENTIALS, password == null ? "" : password);
}

return new InitialContext(properties);
}
catch(Exception e)
{
System.out.println("Unable to connect to WebLogic server at " + url);
System.out.println("Please make sure that the server is running.");
throw e;
}
}

//----------------------------------------------------------------------------
// Utility Methods
//----------------------------------------------------------------------------

public CustomersRemoteHome getHome()
{
return customersRemoteHome;
}
//Main method

public static void main(String[] args)
{
try
{
CustomersTestClient client = new CustomersTestClient();
// Use the getHome() method of the client object to call Home interface
// methods that will return a Remote interface reference. Then
// use that Remote interface reference to access the EJB.
CustomersRemoteHome home=client.getHome();
CustomersRemote r=home.findByPrimaryKey("12");
System.out.println(r.getAddr()+":"+r.getName());
}
catch(RemoteException ex)
{
ex.printStackTrace();
}
catch(FinderException ex)
{
ex.printStackTrace();
}
}
}
出现错误：
