java: reading secure website

ashirazi · 11-09-2004, 10:27 AM

Hi,

Im aware of reading webpages using BufferedReader in java. But How would I read a page that requires authentication i.e. username/pasword? Any hints or clues?

Thanks

This looks helpful: http://javaalmanac.com/egs/java.net/Auth.html?l=rel

If it uses SSL (https), I would suggest reading this: http://java.sun.com/developer/JDCTec...04/tt0817.html

Code:

Im using eclipse and when i click on any of these errors I get a class editor window which says "Source not found - The jar file rt.jar has no source attachment." It then has a button to link the jar file.

Do you have any idea whats with that?

Thanks
