Hello, I have small problem. We have developed a Java/Swin application. This application collects and stores data on local machine. When required this application can post data using HTTP to a password protected URL. (i.e) When invoked fromthe browser this URL asks for a user/password. To make this authetication configurable from my application I have used the my Autheticator that derives from java.net.Authenticator Class At run time it reads the user/password from a properties file and installs threquired authetictation. After this I open a URL connection and post the data. This works great when I post the data from the application when I run the application from the DOS Prompt. But Once the application is downloaded and run Through Webstart , the runtime doesnot take into consideration My autheticator. It doesnot come into the overridden function getPasswordAuthentication(). Webstart pops-up its own dialog box and asks for user/password. Our requirement is that no such dialog box should be shown. I have also tried the fllowing in vain 1.The security setting in JNLP says all-permissions 2.System.setSecurityManager(null) I hope you got the problem I uregenrly need help on this.
