Java™ programs can control when prompting for user ID and password caching occurs. The information from the Sign-On dialog can be used to set the default user ID and cache the password. The following table summarizes when prompting takes place, what information is retrieved, and what information is set.
This table assumes that the Java program allows default user ID processing and password caching, and that you checked the Default User ID box and the Save Password box on the Sign-On dialog.
Use this table for client connections, not for running Java on your server.
