I get exactly the same error message when trying to use the Databaseserver
loginmodule. I use JBoss 4.2.3. In the log there is the following:
javax.security.auth.login.LoginException: java.lang.NullPointerException
| at
org.jboss.security.auth.spi.DatabaseServerLoginModule.getUsersPassword(DatabaseServerLoginModule.java:141)
| at
org.jboss.security.auth.spi.UsernamePasswordLoginModule.login(UsernamePasswordLoginModule.java:206)
|
It seems from the source file, that the Datasource returned is null. It's the
following source in the login module:
InitialContext ctx = new InitialContext();
| DataSource ds = (DataSource) ctx.lookup(dsJndiName);
| conn = ds.getConnection();
|
I configured everything from the documentation.
login-config.xml:
<application-policy name = "nedbDbLogin">
| <authentication>
| <login-module
code="org.jboss.security.auth.spi.DatabaseServerLoginModule"
| flag="required">
| <module-option
name="dsJndiName">java:jdbc/bavnedb</module-option>
| <!--<module-option name="hashAlgorithm">MD5</module-option>
| <module-option name="hashEncoding">base64</module-option>
-->
| <module-option name="principalsQuery">
| select password from USER where
LOGIN_ID=?</module-option>
| <module-option name="rolesQuery">
| select 'Nedb_User', 'Roles' from USER where
LOGIN_ID=?</module-option>
| </login-module>
| </authentication>
| </application-policy>
|
jboss-web.xml:
| <?xml version="1.0" encoding="UTF-8"?>
| <jboss-web>
| <security-domain>java:/jaas/nedbDbLogin</security-domain>
| </jboss-web>
The code for the programmatic login:
| UsernamePasswordHandler handler = new UsernamePasswordHandler(userId,
password);
|
| LoginContext loginContext = new
LoginContext(LOGIN_CONTEXT,
| (CallbackHandler) handler);
| loginContext.login();
|
Do you have any idea what can be wrong?
Thanks in advance
