I dont think, you need all this to login using JAAS. Its pretty simple, you need to have the user.conf in your classpath and add using System.setProperty. Also, i see a problem in the code that you have: anonymous wrote : LoginContext lc = new LoginContext("clientTest", new MyCallbackHandler()); Shouldnt "clientTest" be "userTest" since your user.conf mentions userTest?
