Tomcat DataSource question

["lauradiara@libero.it" <la...@libero.it>]

Hi all,

I have an apache-tomcat(4.0.3) system installed. I use a connection 
DataSource with a Oracle database (I have a resource in server.xml with 
type="javax.sql.DataSource"). 
My question is this. If Oracle DB crashes and it has to been restarted, 
does my web application,that uses DataSource, have to be restarted? 

I have a class with this static block:

static {
    try  {
        Context initCtx = new InitialContext();
        Context envCtx = (Context) initCtx.lookup("java:comp/env");
        DataSource ds = (DataSource) envCtx.lookup(dbName);
        con =  ds.getConnection();
        if (con == null)
          System.out.println("[ERROR] Connection null");
      } catch (Exception ex) {
        System.out.println("[ERROR] Errore = "  + ex.toString() + " \n" 
+ ex.getMessage());
        con = null;
      }
  }
 
and I have a method:


protected synchronized Connection getConnection() {
         while (conFree == false) {
            try {
               wait();
            } catch (InterruptedException e) {
              System.out.println("[ERROR] Exception getConnection() = " 
+ e.toString());
            }
         }
         conFree = false;
         notify();
         return con;
    }

In the servlets of my web application I call getConnection() to take 
the connection: if db is restarted what happen?

Thanks for your help

Laura
