If condition problem

hi,

Why is my If condition not getting executed properly. Anything wrong in code.

while(rs.next())
{
if ( rs.getString(2)== request.getParameter("product"))
{
System.out.println("CAME DOSN");
}
else
{ System.out.println("ELSE part"); }
}

Even though value of rs.getString(2) is equal to value of request.getParameter("product"). IF part is not getting excuted. Only else part been excuted.
I tried to see on console by having system.out.print.... Both values are identical.
rs.getString(2) =HELLO
request.getParameter("product")=HELLO

if the rs can return null then you should check for that also

== tests if the are the same object, equals() tests if the value of two objects is equal.

Okay equals works, but it is still going to else part.

if (rs.getString(2).equals(request.getParameter("product")))

{
System.out.println("Print IF Part");
response.setStatus(HttpServletResponse.SC_MOVED_PERMANENTLY);
String newLocn = "errorUpload.jsp";
response.setHeader("Location",newLocn);
}

as per my code it should redirect to errorUpload.jsp correct ? then why is it also following else part ...

Mick Barry

what make u think it is executing the else block?

My else part has this code:
response.setStatus(HttpServletResponse.SC_MOVED_PERMANENTLY);
String newLocn = "view_current_releases.jsp";
response.setHeader("Location",newLocn);

And I see my page is directed to view_current_releases.jsp

Mick Barry
