cascading method calls on an object

[=?ISO-8859-1?Q?Thomas_Gagn=E9?=]

Is there a way to cascade methods on an object similar to Smalltalk's cascading?

In Smalltalk (server pages) I might:

session
at: #username put: (request getParameterValueAt: 'username');
at: #server put: (request getParameterValueAt: 'server');
at: #password put: (request getParameterValueAt: 'password');
at: #database put: (request getParameterValueAt: 'database').

In Java (server pages) I think I can only:

session setAttribute("username", request.getParameter("username");
session setAttribute("server", request.getParameter("server");
session setAttribute("password", request.getParameter("password");
session setAttribute("database", request.getParameter("database");

You are correct in your analysis: Java has no syntax for what you want
to do. Some methods of some objects allow you to do this though -- see,
for instance, StringBuffer.append.
