I am using following code:
@SuppressWarnings("serial")
public class GuestbookServlet extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws IOException {
resp.setContentType("text/plain");
PrintWriter out = resp.getWriter();
out.println("This is my first Google App");
//----Google User Account Service---//
try{
UserService userService = UserServiceFactory.getUserService();
User user = userService.getCurrentUser();
if (user != null) {
out.println("Hello, " + user.getNickname());
out.println("<a href='"+userService.createLogoutURL("http://
localhost:8888")+"'>Logout</a>");
} else {
resp.sendRedirect(userService.createLoginURL(req.getRequestURI()));
}
}catch(Exception ex){
out.println(ex.getMessage());
}
}
}
hit http://localhost:8888/appname
enter email address like [email protected], and put a comma " , " at the
end of email it produces following exception.. how to validate the
email so that it should not produce exception. and when i enter comma
email address it shows HTTP 500 Internal Server Error unless I washout
all the cookies so that session is lost.
