jsp - Request paramter value is truncated to first part when it contains spaces

I have a strange issue with dropdown boxes in jsp/servlet. Here it is...

  <select name="locdropdown" onchange="javascript:change()" > 
<%
for(LocationDO locationDO : locationList){%>
<option value=<%=locationDO.getLocationName().trim()%>><%=locationDO.getLocationName().trim()%></option> 
<%} %>
</select>

values displayed are:

 BI Sholingar
 BI Mahindra City
 BI Sanand 
 Rolltec_DTA
 Aztec Auto Ltd
 BI Gurgoan

and here is how I try to read it in servlet.

String locclasses = req.getParameter("locdropdown");
System.out.println(locclasses);

assume I select Aztec Auto Ltd then expected output from servlet is same right. But output is Aztec. similarly, if I select BI Sanand, the actual output that comes is BI

Can someone help please

You need to quote the value.

<option value="<%=locationDO.getLocationName().trim()%>">

The space is namely a HTML attribute separator. A browser with a bit decent syntax highlighter would already have hinted it when you have checked the generated HTML by rightclick page > View Source.

<option value=Aztec Auto Ltd>

versus

<option value="Aztec Auto Ltd">
