itry http://localhost:8080/app/register.jsf 我給瀏覽器excption和eclipse堆棧跟蹤控制檯。其他信息不是必須的，請幫助我！ 非常感謝
您標記了MyFaces，但堆棧跟蹤顯示您正在使用Mojarra。你現在在使用什麼JSF實現？你的webapp的'/ WEB-INF/lib'中有沒有JSF庫？你是否意識到JBoss帶有自己的JSF庫？它可能會與你在webapp中放置的那些相沖突，而不在'web.xml'中設置必要的JBoss特定的上下文參數，它應該告訴它使用WAR捆綁的JSF impl。 – BalusC
有人告訴我，當我使用jboss 6時，我不應該將它們添加到lib文件夾中，所以我sid'nt添加任何東西。它不是真的？ – sara
好的。那你爲什麼要標記MyFaces？你知道MyFaces是什麼嗎？ – BalusC
