我正在運行Tomcat 6.0.29並創建了我自己的領域和loginmodule。它們在server.xml中定義的，像這樣：爲什麼Tomcat經理使用我的LoginModule？
<Realm className="mycompany.tomcat.MyRepositoryRealm" appName="My_Realm" userClassNames="mycompany.tomcat.IdentityPrincipal" roleClassNames="mycompany.tomcat.RolePrincipal" useContextClassLoader="true"/>
我已經加入含有這些類圖書館我的tomcat/lib文件夾中。除此之外，我還沒有改變Tomcat的默認配置。
當我啓動了位於http://localhost:9080/manager/html的Tomcat管理器應用程序時，我無法登錄，並且tomcat日誌顯示了我的登錄模塊的錯誤和堆棧跟蹤。
任何想法？謝謝！
編輯：
每請求時，這裏是堆棧跟蹤。我的領域連接到一個JBoss服務，所以這就是爲什麼我得到NamingContextFactory錯誤。
