マルチモジュール Maven アプリケーションの別のモジュールで EJB 2.1 を使用しています。私は間接的な JNDI を使用しています (つまり、java:comp/env/ を使用していません)。また、EJB 2.1 を初めて使用しています。しかし、これは単純なローカル EJB にすぎないため、それほど問題にはなりません。それについての厄介な点は、それが機能していたが、関連する部分を変更せずに突然機能しなくなり、NameNotFoundException を取得していることです。それが機能していたので、物事は正しく行われます。私はそれについてかなり確信しています。最初に私のコード、

今、私の例外のスタックトレース (NamingNotFoundException)
[7/24/12 12:34:26:629 IST] 00001720 GEMEBesUtil W NamingException Occured
com.ibm.websphere.naming.CannotInstantiateObjectException: A NameNotFoundException occurred on an indirect lookup on the name java:comp/env/ejb/CreateAclService. The name java:comp/env/ejb/CreateAclService maps to a JNDI name in deployment descriptor bindings for the application performing the JNDI lookup. Make sure that the JNDI name mapping in the deployment descriptor binding is correct. If the JNDI name mapping is correct, make sure the target resource can be resolved with the specified name relative to the default initial context. [Root exception is javax.naming.NameNotFoundException: Name ejb not found in context "ejblocal:".]
