Problem meeting condition in jsp

Question

Hi,
I have written a small test jsp, which is basically just an input form that allows the user to select a value from a drop down box.
When the form is submitted depending on what value was submitted, I want to display some stocks prices using a specific xml style sheet. The style sheet used is dependant on the choice submitted by the user in the drop down box.
However my problem is that no matter what choice i make, the last condition is always met and the stocks are always displayed using the last xsl style sheet (stocks_short.xsl). None of the conditions in the two if statements are ever met.
I guess this must be something to do with the way I am comparing the request parameters in the if statements? Can anyone please help and let me know what Im doing wrong please?
Code is listed below:
------------------------------------------------------->
<%@ page contentType="text/html" %>
<%
if (request.getParameter("cmbView")== null)
%>
<CENTER>
<H2>User Info Request Form</H2>
<FORM METHOD="GET" ACTION="stocks.jsp">
<select name="cmbView">
<option>pick a display type</option>
<option value="summary">summary</option>
<option value="full">full</option>
</select>
<INPUT TYPE="submit" value="submit form">
</FORM>
</CENTER>
<%
else
%>
<%! String xmlHeader; %>
<%
if (request.getParameter("cmbView") == "summary") <--- this condition is never met
xmlHeader = "<?xml:stylesheet type='text/xsl' href='stocks.xsl' version='1.0' encoding='UTF-8'?>";
else if (request.getParameter("cmbView") =="full") <--- this conditon is also never met
xmlHeader = "<?xml:stylesheet type='text/xsl' href='stocks_long.xsl' version='1.0' encoding='UTF-8'?>";
else <--- this conditon is always met
xmlHeader = "<?xml:stylesheet type='text/xsl' href='stocks_short.xsl' version='1.0' encoding='UTF-8'?>";
%>
<%= xmlHeader %>

Hi,
Do this way;
if (request.getParameter("cmbView") .equals( "summary") )
instead of
if (request.getParameter("cmbView") == "summary")
In the first case you are comparing the objects not the content of the String.Check the docs for the detail.
