Retain option selected value on submit

Hi all,

I have the following code


used for drop down list in my jsp, where utList is an Arraylist of Hashmaps from the backend database table. I am able to display the dropdown box but on submit I am not able to retain the selected value.

I do have a session.getAttribute set for the selected value in my servlet.

Thanks.

How would you go about setting a particular selected option in the HTML? Once you figure that out, you change the JSP to make that happen.

thanks...yeah I know that we have to use <option value="xyz" selected>...but I was wondering how we go about doing the same in that code?

I do have my program working when I use a String to display options, but I'd like to know if there is anyway we can do the same, using EL, when and arraylist of Hashmaps is used, as in the code displayed above?

Thank you

Hint : You can achieve it using EL and ternary operator.

You know what the value of each option is, and you know what the selected value is, just compare them and when they are the same, add the selected attribute.

And no, I won't write the code for you. Give it a try and see what you come up with and we'll take it from there.

It'd be cool if you could post your solution so that others with the same issue can benefit.
