jsp调用EJB出错，请大侠帮忙看看，急急急

dotcom 2002-08-28 06:44:48

我用jbuilder6和Weblogic结合，用jbuilder发布到weblogic后，用jsp调用，lookup()是没有报异常，但是接下来我用到jar里面的类的时候却报错

InitialContext ctx = new InitialContext();
Object ref = ctx.lookup("TimeFunction");

TimeFunctionHome timeFunctionHome;
timeFunctionHome = (TimeFunctionHome) PortableRemoteObject.narrow(ref, TimeFunctionHome.class);
TimeFunction timeFunction = timeFunctionHome.create();
//以上最后三句执行的时候出错：
cannot resolve symbol
probably occurred due to an error in /hello.jsp line 62:
TimeFunctionHome timeFunctionHome;
。。。。。。

给你一个webshpere下的我测试通过的离子，本质上映该一向样的，你看看。

<%@ page import="Converter,ConverterHome,javax.ejb.*, java.math.*, javax.naming.*, javax.rmi.PortableRemoteObject, java.rmi.RemoteException" %>
<%!
private Converter converter = null;

public void jspInit() {
try {
InitialContext ic = new InitialContext();
Object objRef = ic.lookup("java:comp/env/ejb/TheConverter");
ConverterHome home = (ConverterHome)PortableRemoteObject.narrow(objRef, ConverterHome.class);
converter = home.create();
} catch (RemoteException ex) {
System.out.println("Couldn't create converter bean."+ ex.getMessage());
} catch (CreateException ex) {
System.out.println("Couldn't create converter bean."+ ex.getMessage());
} catch (NamingException ex) {
System.out.println("Unable to lookup home: "+ "TheConverter "+ ex.getMessage());
}
}

public void jspDestroy() {
converter = null;
}
