hi sandeep,
here is a sample code which connects to a backend database Oracle; Connection is same for all DBs as you are using open sql commands.
<b>   try {
     String eposta = wdContext.currentContextElement().getEposta();
     String tel = wdContext.currentContextElement().getTelefon();
     String company = wdContext.currentContextElement().getCompany();
     String message = " ";
     String onerikonusu = " ";
     String oneri_mdurum = " ";
     String oneri_odurum = " ";
     String oneri_bfaydalar = " ";
     String oncelik1 = " ";
     String uygulama = " ";
     String tarih = (new SimpleDateFormat("dd-MM-yyyy").format(new java.util.Date()));
     String saat = (new SimpleDateFormat("HH:mm:ss").format(new java.util.Date()));
     //java.sql.Date tarih = java.sql.Date.valueOf(creationDate);
     //java.sql.Time saat = java.sql.Time.valueOf(creationTime);
     if (wdContext.currentContextElement().getMesaj() != "")
        { message = wdContext.currentContextElement().getMesaj(); }
     if (wdContext.currentContextElement().getOneri_konusu() != "")
          { onerikonusu = wdContext.currentContextElement().getOneri_konusu(); }
     if (wdContext.currentContextElement().getOneri_mdurum() != "")
          { oneri_mdurum = wdContext.currentContextElement().getOneri_mdurum(); }
     if (wdContext.currentContextElement().getOneri_konusu() != "")
          { oneri_odurum = wdContext.currentContextElement().getOneri_odurum(); }
     if (wdContext.currentContextElement().getBekfaydalar() != "")
          { oneri_bfaydalar = wdContext.currentContextElement().getBekfaydalar(); }
     if (wdContext.currentContextElement().getOncelik() != "NULL")
          { oncelik1 = onceliktxt.toUpperCase(); }     
     if (wdContext.currentContextElement().getUygulama() != "NULL")
          { uygulama = app.toUpperCase(); }
   InitialContext ctx = new InitialContext();
   javax.sql.DataSource ds =
   (javax.sql.DataSource) ctx.lookup("jdbc/SAPEPPDB");
   java.sql.Connection con = ds.getConnection();
   con.setAutoCommit(false);
   java.sql.Statement stmt = con.createStatement();
     String sql;
      int rows;
      sql = "insert into tmp_feedbacks " +
           "(puid, name, tel, email, company, konu, oncelik, uygulama, mesaj, onerikonusu," +
           "oneri_mdurum, oneri_odurum, oneri_bfaydalar,tarih,saat) " +
           "values ('" + username + "', " +
                     "'" + name + "'," +
                     "'" + tel + "'," +
                     "'" + eposta + "'," +
                     "'" + company + "'," +
                     "'" + konutxt.toUpperCase() + "'," +
                     "'" + oncelik1 + "'," +
                     "'" + uygulama + "'," +
                    "'" + message + "'," +
                    "'" + onerikonusu + "', " +
                    "'" + oneri_mdurum + "', " +
                    "'" + oneri_odurum + "', " +
                    "'" + oneri_bfaydalar + "', " +
                    "'" + tarih + "', " +
                    "'" + saat + "' " +
     stmt = con.createStatement();
     rows = stmt.executeUpdate(sql);
     con.commit();
     stmt.close();
   catch(Exception e){
        IWDMessageManager msgMgr =
                wdComponentAPI.getMessageManager();
   msgMgr.reportException(e.getMessage(),true);
   }</b>
The value <b>ctx.lookup("<jdbc_pool>");</b> depends on your system id.
if your system id is SID the the string has to be <b>jdbc/SAPSIDDB</b>
you can check it via visual admin >> server >> services >> jdbc con.
