JAAS错误：登录失败

Question

i'm building some restful webservices and try to secure them by using JAAS.

but i get the following error:

 javax.servlet.ServletException: Login failed

I created a realm with the following attributes:

JAAS-Context: jdbcDigestRealm
DIGEST-Algorithm: SHA-512
Encoding: Hex
password encryption: none

I try to log in by using HttpServletRequest:

request.login(email, password); //email = test@test.tld, password=<SHA512HEX('testPasswprd')>

Here is the StackTrace:

WARNING:   WEB9102: Web Login Failed: com.sun.enterprise.security.auth.login.common.LoginException: Login failed: null
SEVERE:   javax.servlet.ServletException: Login failed

at org.apache.catalina.connector.Request.login(Request.java:2224)
at org.apache.catalina.connector.RequestFacade.login(RequestFacade.java:1113)

Do you have some ideas?

EDIT:

Sometimes I get a NullPointerException at

request.login(email, password); //both variables and request are set.

This tutorial was tested in Glassfish 4.0 with Java EE 7 application:

1. Expand the Security node.
2. Expand the Realms node.
3. Select the File node.
4. On the Edit Realm page, click Manage Users.
5. On the File Users page, click New.
6. In the User ID field, type a User ID.
7. In the Group List field, type TutorialUser.
8. In the New Password and Confirm New Password fields, type a password.
9. Click OK.

Then set up Default Principal to Role Mapping on the GlassFish Server:

1. From the Administration Console, expand the Configurations node, then expand the server-config node.
2. Select the Security node.
3. Select the Default Principal to Role Mapping Enabled check box.
4. Click Save
