嗯，我正在嘗試爲我的Servlet（在Eclipse中的Tomcat 7上運行）創建JAAS身份驗證，但我收到此錯誤。javax.security.auth.login.LoginException：沒有爲SomeLogin配置LoginModules
He're的完整的堆棧跟蹤： 「`

在context.xml中：
<Realm className="org.apache.catalina.realm.JAASRealm"
appName="GdiaLogin"
userClassNames="org.ktu.gdia.core.security.UserPrincipal"
roleClassNames="org.ktu.gdia.core.security.RolePrincipal" />
在的jaas.config（我敢肯定的Tomcat找到它是正確的，因爲我在eclipse中爲「運行配置」添加了正確路徑）：
GdiaLogin {
org.ktu.gdia.core.security.GdiaLoginModule required debug=true;
};
我假設必須有有毛病的jaas.config ...
我的登錄模塊，不知道如果我需要在這裏提供它，雖然，這幾乎是直接從一個教程我一直在下面：

編輯：在eclipse我的運行配置參數爲Tomcat：
-Dcatalina.base="D:\Dropbox\EclipseWorkspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp7" -Dcatalina.home="D:\Servers\GenTreeUploader_Tomcat7" -Dwtp.deploy="D:\Dropbox\EclipseWorkspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp7\wtpwebapps" -Djava.endorsed.dirs="D:\Servers\GenTreeUploader_Tomcat7\endorsed" -Djava.security.auth.login.config="D:\Dropbox\EclipseWorkspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp7\conf\jaas.config"
嘛？有任何想法嗎？
你在哪裏放置了你的context.xml文件？它需要位於META-INF文件夾內。 – JamesB
@JamesB它在WebContent/META-INF /文件夾中，以及自動生成的MANIFEST.MF –
