Get list box value in servlet

Hello,
Use <%= request.getParameter("value") %> not getParameterValues method.

-FA

you have tried the following

http://www.roseindia.net/servlets/SelectColor.shtml
http://www.coderanch.com/t/283368/JSP/java/pass-selected-values-Combo-box

I already use request.getParameter("value")  but cannot work, this because in the list box have a multiple value because after I add the list of option I want to get all the values:
For example:
         UK
         US
         New Zealend

<< but cannot work,>>
what does this mean? can you share the result of
System.out.println(request.getParameter("value"));

Hello,
Actually...  with a MULTIPLE select box, you will need to use a
StringTokenizer, since the parameter value will be a comma separated
list of all select options...



Hope that helps!

for (Enumeration p = request.getParameterNames() ; p.hasMoreElements();) {
   name = p.nextElement().toString() ;
   value = req.getParameter(name) ;
   if(name.equals("NAME")) {
      st = new StringTokenizer(value, ",");
      while (st.hasMoreTokens()) {
         // do something with each token.
         System.err.println(st.nextToken());
      }
   }
}

Select allOpen in new window

Use <%= request.getParameter("learnCountry") %>

-FA

It didn't get the value of the country

<select id='learnCountry' name='learnCountry' size="6" style="width:200px" <%=disabledLearnMode%>>

i think  the select box is disabled in your code then value will not come in servlet.

try once without  disabling the select box then value will come in servlet..

don't use <%=disabledLearnMode%> in select tag ;i think you are disabling the select box.

try once without  disabling the select box then value will come in servlet..

First , is it multiple select box?  Add multiple
<select multiple id='learnCountry'
what is output of this  <%=disabledLearnMode%>?
req.getParameterValues is correct way to get multiple selected values.

Yes, it's multiple list box, so can select multiple values.

I already add <select multiple id='learnCountry'

the <%=disabledLearnMode%> is for disabled the list box.  Because I have make an option whether to disable it or not.  In current situuation I'm not disabled it. In the servlet I used req.getParameterValues and the result is null also when used req.getParameter.

In servlet  are you getting other values correctly?
May be you are not submitting form correctly in JSP.

Good
