Hi, I've the same problem as mactex. Struggling for 3 days with: javax.security.auth.login.LoginException: java.lang.NullPointerException I try to use database as user repository in Drools 4 BRMS or Drools 5 Guvnor. Got similar configuration as mactex except that I had to point policy from login-config.xml in the components.xml file of the guvnor/brms: <security:identity authenticate-method="#{authenticator.authenticate}" jaas-config-name="oracleDS"/> conn = ds.getConnection(); returns null. Please can anyone help us? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4257611#...
