The WebSphere configuration file is really complicated. These days have changed, and I can't run my application. One heart, unloading. It took an hour to re-configure it. Very smooth, it can control the permissions after startup. But still don't help me set up Principal in the connection, httpservletRequest.getuserPrincipal () is NULL. I guess WebSphere default loginmodule just do verification actions, no authorization operation, whether the role can access the web application control seems to be a "false" function made by the "Map User / Group" function. Still depressed, look at the RedBook today, see if the new discover of LoginModule, no longer collect information, let IBM's technical support to solve their laboratory! Today, I don't bother myself, take a hot bath, watch a film, sleep well.
