zm1616 2004-11-22 02:52:06

我早网上找了一篇文章，但怎么试都不成功
<%@ page import="org.omg.CORBA.ORB" %>

<%@ page import="org.omg.CosNaming.NamingContext" %>

<%@ page import="org.omg.CosNaming.NamingContextHelper" %>

<%@ page import="org.omg.CosNaming.NameComponent" %>

<%@ page import="org.omg.CORBA.ORB" %>

<%@ page import="market.*" %>
//我的easerver组件
<%@ page import="CTS.PBUserException" %>

<HTML>
<HEAD>
</HEAD>
<BODY>

<%
String s1;
String s2;

n_market nvo;

java.util.Properties props = new java.util.Properties();

props.put("org.omg.CORBA.ORBClass", "com.sybase.CORBA.ORB");

props.put("com.sybase.CORBA.NameServiceURL", "iiop://localhost:9000");

ORB orb = ORB.init((String[]) null, props);

try

{

NamingContext context = NamingContextHelper.narrow(orb.resolve_initial_references("NameService"));
//这个NameService我一直不知道改填什么？

NameComponent[] name = { new NameComponent("market/n_market")};

SessionManager.Factory factory = SessionManager.FactoryHelper.narrow(context.resolve(name));

nvo = n_marketHelper.narrow(factory.create("jagadmin", ""));

}

catch(org.omg.CORBA.ORBPackage.InvalidName aException){}

catch(org.omg.CosNaming.NamingContextPackage.NotFound aException){}

catch(org.omg.CosNaming.NamingContextPackage.CannotProceed aExceptiont){}

catch(org.omg.ConNaming.NamingContextPackage.InvalidName aException){}

try

{

String rt = "";

rt = nvo.nf_test();

out.println(rt);
}

catch (CTS.PBUserException e){}
