Whenever I try to connect to a Oracle 10g Database on my machine, I encountered this error message: ORA-01882: timezone region not found. This was true for SQl plus as well as while connecting using JDBC. The problem was Oracle 10g did not have "Asia/Kolkata" as a timezone region in the V$TIMEZONE_NAMES view. My machine however was configured to use the above timezone. When I changed the timezone to "Asia/Calcutta" on my machine, things started working fine. Little did the residents of Kolkata realize that changing the name of their city from Calcutta to Kolkata would have such implications!!! While most software has already started using the new name along with the old name, there are some old software that still does not support the new name. Of course, we can configure oracle to use the new name as well..

I came across this really useful article that allows you to easily swith between network profiles on windows XP.. http://windowsheaven.wordpress.com/2006/07/08/how-to-create-multiple-network-profiles-on-windows-xp2000/

I recently got involved in a project that used GWT and Spring. One of the first things that struck me was the lack of support for Dependency injection frameworks in GWT. So we had to come up with a Spring controller that looked similar to this public class SpringAwareGWTService extends RemoteServiceServlet implements Controller { private ThreadLocal servletContext = new ThreadLocal (); public final ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) { servletContext.set(request.getSession().getServletContext()); doPost(request, response); servletContext.set(null); return null; } public ServletContext getServletContext() { return servletContext.get(); } } Here, what we have done is create a spring controller that is also a GWT remote servlet. Only thing to note is that the GWT remote servlet was never intented to serve as a controller. Also we will force spring to accept the response provided b
