servlets, a set of JSPs as web frontend and two applets
for managing bug reports and administrating Bug Base.
The main servlet is
This servlet receives a

constructor. This does not fit to the servlet API. Hence,

will be fixed in the future.
The communication with the main servlet is handled by
This client is used both in the two applets and for the JSPs.
The JSP architecture follows the

action servlet is used. Attributes that are used through
the whole application are initialized by
