java me - In J2ME Using LWUIT library. How to call another Form? -


how call form? when used form.show() method, component of form not displayed.
example...

firstform.java

public class firstform extends midlet implements actionlistener {     form frm_first = new form("first");     public command cmd_login;     public void startapp()     {         display.init(this);         cmd_login = new command("login");         frm_first.addcomponent(cmd_login);         ......     }     public void pauseapp() {}      public void destroyapp(boolean unconditional) {}      public void actionperformed(actionevent ae)     {         command cmd = ae.getcommand();         string strcmdname = cmd.getcommandname();          if (strcmdname.equals("login"))         {              //how call login form         }     } }

login.java

public class login extends form implements actionlistener {      form frm_login = new form("login");      button btn_login = new button("login");      public login()      {        ....       . ....      } }

first have create form in class firstform. form frm=new form("first form"); add command cmd_login in form frm.addcommand(cmd_login); set command listener form frm.setcommandlistener(this); & need implements commandlistener in firstform not actionlistener. in public void commandaction(command c, displayable d) { have write code go second form. & 1 thing noticed in login class, extending class form & creating form object in login class... if using extend class form dont create form object. thanks
