There are many ways to implement logins, depending on the server side you use.
If you use servlets then the servlet spec will guide you: http://jcp.org/aboutJava/communityprocess/pr/jsr315/index.html Look at <login-config/>, <auth-method/>, <realm-name/>, <security-role/>, <security-role/> tag description Once web.xml is configured, you need to configure your realm. This part is server-specific. If you use Jetty 6.1.x (the version embedded into GWT distribution), then look at org.mortbay.jetty.webapp.WebAppContext's securityHandler, which is configured in jetty-web.xml. If you want to use JAAS for authentication and authorization, configure securityHandler with org.mortbay.jetty.plus.jaas.JAASUserRealm. JAASUserRealm itself requires module configuration. If you want to use a datastore to keep user credentials, then conigure the module with org.mortbay.jetty.plus.jaas.spi.DataSourceLoginModule. Other servers (including GAE) have their own settings, I'm just afraid I'm getting too specific here... -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
