我有这个非常简单的代码（Glassfish 3.1.2）：
Context ic = new InitialContext();
ConnectionFactory connectionFactory = (ConnectionFactory) ic.lookup("jms/ConnectionFactory");
但第二行抛出一个 Exception ：
SEVERE: javax.naming.NamingException: Lookup failed for 'jms/ConnectionFactory' in SerialContext[myEnv={java.naming.factory.initial=com.sun.enterprise.naming.impl.SerialInitContextFactory, java.naming.factory.state=com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl, java.naming.factory.url.pkgs=com.sun.enterprise.naming} [Root exception is javax.naming.NameNotFoundException: jms]

你有一个想法，因为这 2 行代码是“标准的”。Tkx
