i went through all posts and tried everything but my problem is not resolved yet.
here i add my code for your reference.

I put collection in request scope and in config file also.

here my html:select tag with optionsCollection.

  <html:select property="citynames">
				<html:optionsCollection name ="LoginForm" property="citylist" value="CityId" label="CityName" />
	</html:select>  

and Action File

 public ActionForward execute(ActionMapping mapping ,ActionForm form,HttpServletRequest request,HttpServletResponse response)throws Exception
	{
		LoginForm loginform = (LoginForm)form;
		
         Collection citylist = new ArrayList();
  		HttpSession session = request.getSession();
         
        List<City> citydetails = objFirstloginHome.getcitydtls();
  		for(City city : citydetails)
  		{
  			citylist.add(new com.vanilla.object.CityData(city.getCityId(),city.getCityName()));
  		}
  		
  		loginform.setCitylist(citylist);
  		
  		request.setAttribute("citylist",citylist);
  		return mapping.findForward(SUCCESS);
		
	}   

Please let me know solution for this

Your Help will be greatly appriciated Thanks in Advance

Try,

<html:select property="citynames">
    <html:optionsCollection name ="citylist" property="citynames" value="cityId" label="cityName" />
</html:select>

Hi Sagar,
Thanks for your reply
i tried as you mention.

but now he cant find bean in scope

  javax.servlet.ServletException: Cannot find bean: "cityList" in any scope
	org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:867)
	org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:800)

	org.apache.jasper.servlet.JspServlet.service(JspServlet.java:248)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:856)
  

my struts config xml file

    <form-beans>
 	<form-bean name ="LoginForm" type= "com.vanilla.form.LoginForm"/>
 </form-beans>
  
  <global-forwards>
  	<forward name="login" path="/login.do"/>
  </global-forwards>
  
   <action-mappings>
  	<action input="/login.jsp" name ="LoginForm" path="/Login" scope="request" type ="com.vanilla.action.LoginAction">
  		<forward name="success" path="/login.jsp"/>
  		
  	</action>
  </action-mappings>  

i use request.setAttribute("cityList",cityList);

in my jsp file as <%request.setAttribute("cityList","cityList");%>
after that i got
No getter method for property: "cityNames" of bean: "cityList" error.


then i replace request with session scope in config and action file as

and session.setAttribute("cityList",cityList);

but still not any progress

both are not worked for me.

Your help will be greatly appriciated.

I think the property is "cityName" and NOT "citynames"
Why are you setting request attribute in JSP, there is no need. Also the example I given previously purely based on some assumption and understanding of your code snippet. The given link describe all the attributes for html:optionsCollection tag.
