为什么我在Weblogic 下配了javamail session 后lookup session时会出错？

北极海hein 2003-03-28 10:14:23

weblogic javamail配置内容以下：
name: BibleMailSession
JNDIName: BibleMailSession
Properties:
mail.transport.protocol=smtp
mail.store.protocol=imap
mail.host=smtp.mycompany.com
mail.user=test
mail.debug=true
注：已经Targets
在Targets完后weblogic显示以年信息：
DEBUG: not loading system providers in <java.home>/lib
DEBUG: not loading optional custom providers file: /META-INF/javamail.providers
DEBUG: successfully loaded default providers

DEBUG: Tables of loaded providers
DEBUG: Providers Listed By Class Name: {com.sun.mail.smtp.SMTPTransport=javax.m
il.Provider[TRANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Sun Microsystems, In
], com.sun.mail.imap.IMAPStore=javax.mail.Provider[STORE,imap,com.sun.mail.imap
IMAPStore,Sun Microsystems, Inc], com.sun.mail.pop3.POP3Store=javax.mail.Provid
r[STORE,pop3,com.sun.mail.pop3.POP3Store,Sun Microsystems, Inc]}

RANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Sun Microsystems, Inc]}
DEBUG: not loading optional address map file: /META-INF/javamail.address.map
请问从上面的信息看，我的javamail session是否正确？或存在什么样问题？

我用JBuilder写了以下程序片段：

//lookup mail session in JNDI
Hashtable ht = new Hashtable();
ht.put( Context.INITIAL_CONTEXT_FACTORY ,"weblogic.jndi.WLInitialContextFactory" ) ;
ht.put( Context.PROVIDER_URL , "t3://xhy:7001" ) ;
ht.put( Context.SECURITY_PRINCIPAL , "xhy" ) ;
ht.put( Context.SECURITY_CREDENTIALS, "12345678" ) ;

InitialContext ctx = new InitialContext( ht );
//ctx.lookup("BibleMailSession") ;
Session session = (Session) ctx.lookup("BibleMailSession") ;

//set message with to ,subject, and message text
Message msg = new MimeMessage( session );

当执行到Session session = (Session) ctx.lookup("BibleMailSession") ;这句时出现以下错误：

javax.naming.ConfigurationException. Root exception is java.rmi.MarshalException: error marshalling return; nested exception is:
java.io.NotSerializableException: javax.mail.Session

End server side stack trace

然后我也用了implements java.io.Serializable序列化了我写的类，还是这样。
请高手帮帮忙！
