We can replace of some kind of databases using Oacle Coherence?

Question

We can replace of some kind of databases using Oacle Coherence?
Some kind of database can be replaced by Oracle Coherence using the Serialization Paged Cache as the backing storage for the service and using the Serialization Paged Cache as the backup store on disks.
Do you agree with me?

Answer 1

So far basically what I did for the connection was create a constant equal to the name of the database, in the servlet. I will post my Servlet code so far, and I suppose it would help people with either I am going about this all wrong, or on the right track.
public class SMServ extends javax.servlet.http.HttpServlet{
      private static void initialize()throws SQLException {
      String dataSourceName = Constants.MY_DS;
      try{
      Context wocContext = new InitialContext();
      DataSource ds = (DataSource)wocContext.lookup(dataSourceName);
      Connection conn = null;
      conn = ds.getConnection();
      }catch(NamingException ne){
public void doGet(HttpServletRequest req, HttpServletResponse res)
          throws ServletException,IOException{
RequestDispatcher rdSearch =
getServletContext().getRequestDispatcher("/RTMain.jsp");
if (rdSearch != null)
rdSearch.forward(req,res);
}The doGet is there, because what is supposed to happen is the Servlet is supposed to be hit first then go to the jsp. My jsp basically just has a button sitting on it, all I am trying to get out of this is, a button click on the jsp will trigger a hardcoded SQL statement to pull data. As most of you can understand, my purpose is to see this relationship working so I can understand it. I am not sure if I am completely right on my DS setup there. The Constants.MY_DS is from another class, that is basicallypublic static final String MY_DS = "name of my database"; Name of the database being the one I have an established connection to in rad.
