example.jsp code segment:
...
<input type="hidden" name="submit_flag" value="1">
<html:select property="type">
<html:option value="1">1</html:option>
<html:option value="2">2</html:option>
<html:option value="3">3</html:option>
</html:select>
...
Don't forget adding the set and get method for submit_flag to the
exampleForm.java
exampleAction.java code segment:
...
public ActionForward perform(ActionMapping actionMapping, ActionForm
actionForm, HttpServletRequest httpServletRequest, HttpServletResponse
httpServletResponse) {
MessageResources messages = getResources();
Locale locale = getLocale(httpServletRequest);
String flag =
httpServletRequest.getParameter("submit_flag")==null?"":httpServletRequest.g
etParameter("submit_flag");
if(flag.equals("")){
( (exampleForm) actionForm).setType("2"); /** set the defualt
selection **/
return (new ActionForward(actionMapping.getInput())); /**
here the example.jsp will be show **/
}
......
...
}
and you have to visit the exampleAction(something like exampleAction.do)
instead of example.jsp for the webpage view.
that's my solution, I hope it will be helpful.
