FileRegistrySample.java file


This provides an example of the FileRegistrySample.java file.

The user and group information required by this sample is contained in the users.props file and groups.props file files.

The samples that are provided are intended to familiarize you with this feature. Do not use these samples in an actual production environment.

/**
 *  The main purpose of this sample is to demonstrate the use of the  
 *  custom user registry feature available in WAS. This 
 *  sample is a file-based registry sample where the users and the groups  
 *  information is listed in files (users.props and groups.props). As such 
 *  simplicity and not the performance was a major factor. This 
 *  sample should be used only to get familiarized with this feature. An 
 *  actual implementation of a realistic registry should consider various 
 *  factors like performance, scalability, thread safety, and so on.
