javax.security.auth.login.LoginException： No LoginModules for SomeLogin
2022-09-02 20:44:22
好吧，我正在尝试为我的Servlet创建JAAS身份验证（在Eclipse中的Tomcat 7上运行），但是我得到了这个错误。
他是完整的堆栈跟踪：“”

在上下文中.xml：
<Realm className="org.apache.catalina.realm.JAASRealm"
appName="GdiaLogin"
userClassNames="org.ktu.gdia.core.security.UserPrincipal"
roleClassNames="org.ktu.gdia.core.security.RolePrincipal" />
在jaas.config中（我很确定Tomcat找到了正确的路径，因为我在eclipse中添加了带有“运行配置”参数的正确路径）：
GdiaLogin {
org.ktu.gdia.core.security.GdiaLoginModule required debug=true;
};
我假设 jaas.config 一定有问题...
我的登录模块，不确定我是否需要在这里提供它，但是，它几乎直接来自我一直关注的教程：

编辑：我在 eclipse for tomcat 中的运行配置参数：
-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"
井？有什么想法吗？
