As an alternative, you might look into developing an app and distributing it (for cash) in the Android Market and/or other Android app stores.

I want the client that will pay me for the contract development .
for example :- freelancer.

when it is necessary to save as "" ?
I fount too many people saving the file as ""(double inverted) , they don't got any reason to do that.

I never save the file with Double Inverted...... , never get any problem.

Matthew Brown wrote:Firstly, you should do stuff in the Servlet init() method, not the Servlet constructor. That gives you access to the ServletContext.

Secondly, doing work there is fine if only one servlet is going to need it. But in many applications you're going to have things - like database details - that are needed by several servlets. But you only want to do it once. Using a ContextListener allows you to perform actions after the context is ready, but before any servlets are created.

what if I want to use diffeerent databases for different servlets.......

getAtribute - This is used for getting the parameters set previously in another or the same JSP or Servlet page. Basically, if you are forwarding or just going from one jsp/servlet to another one, there is no way to have the information you want unless you choose to put them in an Object and use the setAttribute to store in a Session variable. Using getAttribute, you can retrieve the Session variable

in getAttribute() you are talking about the Object , where is the Object here ???
please explain in brief , if possible
thanks , in advanced ......
