HI,
I wish to get the values from the drop down menu selected by a user from the HTML page and pass this value into my servlet program for processing.
In my servlet program, I've used the getParameter() function to obtain the value from the drop down menu selected.
<SELECT name=Day>
<OPTION value="" selected>- Select -</OPTION>
<OPTION value=Sunday>Sunday</OPTION>
<OPTION value=Monday>Monday</OPTION>
<OPTION value=Tuesday>Tuesday</OPTION>
<OPTION value=Wednesday>Wednesday</OPTION>
<OPTION value=Thursday>Thursday</OPTION>
<OPTION value=Friday>Friday</OPTION>
<OPTION value=Saturday>Saturday</OPTION>
</SELECT>
String days= request.getParameter("Day");
System.out.println("DAY =" +days);
However, the value of the parameter "day" seems empty. May I know what is the correct method of getting the value selected from the drop down menu into my servlet? It did work when I use Javascript functions to extract it though (function getDay() in frmLockOut.html).
Attached are my JSP(frmLockOut.html) and Servlet(AdmProfileLockOut.java- see function add( ) ) source code files for reference.
Thanks
Danny

Don't attach things, I won't open them.
Most likely you didn't place the select inside an html form which would cause the value to not be passed in the request.

Wrong way to ask a question. We're not here to do your bidding at your whim. Maybe you should have started researching sooner if you're in a hurry now.
the multiselect is not possible with a dropdown, only with a selectbox.
You can get the values with getParameterValues(String) on the ServletRequest.
The API docs will give you more information.
