Question is not clear.

Is the form part of JSP above?
Where is your select showing all options?

So in your form, you want to display only 4th element of the list as a select option?

Then, just use ${empList[4]} as the option. No need for <c:forEach>.
Or if you want to display a property value of employee, use ${empList[4].name}

Hi

i put the code like this



And the select box is wrongly populated

Check the image, the select list retrives all the index [0,1,2,3,4] instead of only 4

What's wrong??

what objects are in empList? and what properties?
What property of elements are you trying to display in select?

Hi

what objects are in empList? it is query list
and what properties? (code, name, email, telefone and type of employee)
What property of elements are you trying to display in select? I want to use the properties of Tipo (type of employee)
As you can see by the image, the list works, i just want to use values of Tipo (last index) into a select form

Follow the arrows

Check the image

Then this should work.
Please adjust names as per your real values.

If you still can't see anything, please print the ${empList[4]} using <cut> tag before the form.
See also the source.

It looks like the form is to add a new emp. If this is the case you should not be using the type off of the employees in the list in the select. There could be duplicate or missing types. It looks like types is a predetermined set of objects. I would populate that in your controller. Maybe something like below (not tested)



Once types is on the model simply use them in your form
