我不断收到同样的错误，我已经更改了指定 jaas 配置文件位置的 tomcat7w 文件

        javax.security.auth.login.LoginException: No LoginModules configured for    JaaSExample:
        at javax.security.auth.login.LoginContext.init(LoginContext.java:273)

我已经将这个 tom 添加到我的 tomcat7w.exe 文件中。

    -Djava.security.auth.login.config=C:\Program Files (x86)\Apache Software                 Foundation\Tomcat 7.0\conf\jaas.config

还有就是我也有这个境界

    <Realm className="org.apache.catalina.realm.JAASRealm" 
    appName="JaaSExample"
    userClassNames="Security.UserPrincipal" roleClassNames="Security.RolePrincipal" />

所以我错过了什么？请帮我，

我正在使用netbeans，tomcat 7.0.47。

thank you very much,

我已决定使用 glassfish！

根据http://tomcat.apache.org/tomcat-7.0-doc/realm-howto.html#JAASRealm

您应该为 Java 设置 login.config 文件，并通过将其位置指定给 JVM 来告诉 Tomcat 在哪里找到它，例如通过设置环境变量：JAVA_OPTS=$JAVA_OPTS -Djava.security.auth.login.config=$CATALINA_BASE/conf/jaas.config

添加

对于 Windows 打开 startup.bat 添加以下行：set JAVA_OPTS=%JAVA_OPTS% -Djava.security.auth.login.config=%CATALINA_HOME%/conf/jaas.config after okHome

例如

set JAVA_OPTS=%JAVA_OPTS% -Djava.security.auth.login.config=%CATALINA_HOME%/conf/jaas.config
set "EXECUTABLE=%CATALINA_HOME%\bin\catalina.bat"
