request.getParameter() not working

[sony sa]

hi
i am using the following code

 
<% 
 
if(request.getParameter("lst") != null){
out.println("lhi");
irs.last();
}
else
if(request.getParameter("nxt") != null){
out.println("hin");
irs.next();
}
else
if(request.getParameter("prev") != null){
out.println("phi");
irs.previous();
}
else
if(request.getParameter("frst") != null){
out.println("fhi");
irs.first();
}
else
{
out.println("old");
irs.first();
}
%>
 
 

next,first,last,previous are buttons on my form.
and on all the button clicks i am calling one javascript function as follows:

  
function func(){
     document.frmitem.action=document.location
     document.frmitem.submit()
    }

but the navigation is not working properly.
for the first time the default record is coming, but when i click
any button of above mentioned the last record is only coming,
as in the coding it is the first condition to be checked

can anyone help in this matter
i dont know exactly where i am going wrong

thanks

just remove all the else from your scriplet then you will get only the first record

because i think none of your buttons are null.

Am I right in thinking that irs is a JDBC ResultSet? Does the i mean it's an instance variable? If so, are you sure it's not a FORWARD_ONLY ResultSet (the default). If it is then you can't go backwards. That may be your problem.

i have code like this

 
Statement istmt=icon.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_READ_ONLY);
 

its working properly for first and last
but not for next and previous
thanks

It's not very clear from the code you've given what might be going wrong. For example, do your debug prints come out in the response to indicate the correct statement block was entered? What happens if you click the last button and then the first button? Have you tested Adeel's hypothesis that the button parameters are never null? Are you sure that the names on your form buttons are actually what you think they are?
