使用jaas，Glassfish v3.1和服务器3.0创建简单授权时遇到问题。
我根据David Heffelfinger的书“使用GlassFish 3 Application Server编写Java EE 6”来配置web.xml，sun-web.xml，但仍有问题。我会很高兴能有所帮助的任何人。
的web.xml：
<security-constraint>
<web-resource-collection>
<web-resource-name>Admin Pages</web-resource-name>
<url-pattern>/add/*</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<auth-constraint>
<role-name>admin</role-name>
</auth-constraint>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>
<security-constraint>
<web-resource-collection>
<web-resource-name>AllPages</web-resource-name>
<url-pattern>/*</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<auth-constraint>
<role-name>user</role-name>
</auth-constraint>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>customRealm</realm-name>
</login-config>
sun-web.xml中：
<sun-web-app>
<security-role-mapping>
<role-name>admin</role-name>
<group-name>ADMIN</group-name>
</security-role-mapping>
<security-role-mapping>
<role-name>user</role-name>
<group-name>USER</group-name>
</security-role-mapping>
</sun-web-app>
领域：
JAAS Context: jdbcRealm
JNDI: jdbc/users_groups
User Table: v_user_role
User Name Column: username
Password Column: password
Group Table: v_user_role
Group Name Column: group_name
Digest Algorithm: MD5
当我尝试打开某个页面时，我会获得登录表单，但在输入正确（或不正确）登录并通过后，我会获得stacktrace：
