A method, system, and computer program product code for dynamically refreshing user credentials in a distributed processing environment. The present invention provides for fast, local refresh of credentials by a server if the credentials expire during an on-going secure operation. This technique avoids the need for rolling back the operation and requiring the client to restart after acquiring fresh credentials. The ability for a systems administrator to invalidate credentials which have been compromised is maintained.

Dynamic credential refresh in a distributed system

Tree navigator graphical user interfaces are provided which execute on user queries for data asynchronously, and which may display information obtained as a result of a query as soon as it is available, even though additional responsive information is not yet available. These tree navigator graphical user interfaces may also be designed to anticipate future queries for data based on past or current queries, and pre-load data into the graphical user interface which is responsive to the anticipated future queries. The tree navigator graphical user interfaces may additionally use &ldquo;placeholder objects&rdquo; and &ldquo;loading icons&rdquo; to notify the user regarding the loading status of the data associated with a particular branch of the tree.

The computer is enhanced to include software processes for detecting the contents of data to be displayed and, responsive thereto, for changing the user interface selected for display and use. These processes determine which of a plurality of possible user interfaces shall be loaded into the computer memory for employment on the display for user interaction therewith so that, for example, functionally rich user interfaces will be employed for adult use of a given data load, but simplified user interfaces may be employed for the same data when a child desires to use the system. The entire user interface is changed based on data type or content as compared with a register of desired user interfaces for differing types or contents of data to be displayed.
