Jsp combo box

I'm having trouble with a jsp search page in which I have 2 combo boxes and one submit button.
Both combo boxes retrieve data from an access db.
The problem is how to specify from which combo the request is sent.
I tried this piece of code but it didnt work:

if (request.getParameter("combo1") != null) {
execute this code;

} else if (request.getParameter("combo2") != null) {
execute that code;
}

Thanks for your help.

Add a entry -1 as the first entry in both the combo boxes.Then you will know which entry is selected

The if condition looks ok for me, what if you try to output the parameter combo1 and comb2?

Example:

System.out.println("combo1 = " + request.getParameter("combo1"));
System.out.println("combo2 = " + request.getParameter("combo2"));

And if needed, you can post your jsp scripts here.

Add like this
 <select size="1" name="combo1">
    <option value="-1"></option>
    <option value="34">34</option>

    <select size="1" name="combo2">
    <option value="-1"></option>
    <option value="34">34</option>

I am mentioning about this
<option value="-1"></option>

The problem is not about knowing which entry is selected but rather which combo is selected.
Therefore, it excutes both codes and display all the html that comes with both combos.

hi,
I have finally found the solution, the code goes like this:

if ((request.getParameter("NameCombo") != null) && (request.getParameter("DeptCombo").equals("Select by Department"))) {
execute this code;
}

if ((request.getParameter("DeptCombo") != null) && (request.getParameter("NameCombo").equals("Select by Name"))){
execute that code;
}
the problem was to get the parameter sent by the combo that was not selected.
Anyway thanks for your comments.
