EJB をルックアップする方法はいくつかあります
このルックアップを使用して ejb サーバーに接続できますが、ConsoleClient を使用する場合のみです。
"ejb:" + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + viewClassName)
Tomcat アプリケーション サーバー (Spring MVC プロジェクト) でこのルックアップを試みると、このルックアップは機能しません。Jboss は ClassNotFoundException で応答します。
別のjndiルックアップ名が必要だと思いますか? 残念ながら、ウェブ上で役立つ情報を見つけることができませんでした。

クラスパスに ejb-project.jar を追加しました。また、春のプロジェクトに ejb パッケージを追加し、そこに置きましLoginBeanRemoteた。
これまでのところ、プロジェクトは ClassNotFound エラーで応答しません。作成した LoginBeanRemote をデバッグすると、次の内容が含まれます。
Proxy for remote EJB StatelessEJBLocator{appName='foo_business', moduleName='foo_business', distinctName='', beanName='LoginBean', view='interface foo.business.login.LoginBeanRemote'}
ルックアップ中に例外はありません。
LoginBeanRemote remote = (LoginBeanRemote) context.lookup("ejb:"
+ appName + "/" + moduleName + "/" + distinctName + "/"
+ beanName + "!" + viewClassName);
return remote;
Bean の関数を呼び出そうとすると、例外が発生します
System.out.println(remote.helloBean());
