must be an absolute path, starting with a forward slash, or a complete URL with a scheme, server name, port, and path. If the location is a relative path, the sendRedirect() method will throw an IllegalStateException. One reason your portlets may need to redirect the user to another page is to obtain access to pages protected by Single Sign-On (SSO) authentication. A common method of providing SSO is to redirect the user to a login page hosted on another server. The user authenticates to the SSO server, and receives an authentication token. Typically, the user goes to an SSO login page with a URL like http://security.greenninja.com/login url=http://portal.greenninja.com/portal. Upon a successful login, the SSO page redirects the user to the URL from the parameter, with an authentication token passed as a parameter. The portal takes the authentication token and verifies its authenticity with the SSO server through another channel such as a web service or a Remote Method Invocation (RMI) connection. We discuss SSO in 8. Our example of a portlet redirect simply redirects the user s browser to the Apress web site if the user selects the only link on the portlet. The link submits an action request, and the processAction() method sends a redirect back through the portal to the user s browser. The user will leave the portal entirely and will see only the Apress page. A friendlier approach would be to allow the user to open the Apress page in a new window from the portlet, using the standard HTML for setting a target on an <A> element:

The final line gets the current hour. The T-SQL DATEPART function must be used here since no HOUR function is analogous to the YEAR function. Note that T-SQL doesn t provide a time specifier for extracting a complete time, and it doesn t have a separate TIME function: datepart(hour, getdate()) 'hour' You can format dates and times and alternative functions for extracting and converting them in various ways. Dates and times can also be added and subtracted and incremented and decremented. How this is done is DBMS-specific, though all DBMSs comply to a reasonable extent with the SQL standard in how they do it. Whatever DBMS you use, you ll find that dates and times are the most complicated data types to employ. But in all cases you ll find that functions (sometimes a richer set of them than in T-SQL) are the basic tools for working with dates and times.
