Dsplaying value from db in jsp dropdown

Question

I have a form in which i can search with a particular acknowledgement number. It then checks if its present in the db or not. If the value is present in the db then it returns some records from the db and displays in the form. I am using struts 2.

My problem is there are some dropdowns in the form. I am displaying the value from the db in he form using the following struts tag: (suppose fieldOne is a text filed and fieldTwo is a dropdown)

<s:textfield name="fieldOne" label="fieldOne" id="fieldOne" value="%{fieldOne}" />

<select name="fieldTwo" id="fieldTwo" value="%{fieldTwo}">
<option value="Select">Select</option>
<option value="Male">Male</option>
<option value="Female">Female</option>
</select>

fieldOne is coming properly. But i am not sure how to display the dropdown value of fieldTwo. If i write <s:textfield name="fieldTwo" label="fieldTwo" id="fieldTwo" value="%{fieldTwo}" /> it will display the value. But I want to show it in a dropdown list. Ant suggestion is highly appreciated.

Answer 1

you need arraylist to populate the dropdown from db.something like this,

    <s:select key="selectedValue"  id="city" name="city" list="cityList" label="Select City"/>

in action class

static List<String> cityList = new ArrayList<String>();
//create getters and setters

in execute method of action class.

cityList = new ArrayList<String>();
cityList.add("male");
cityList.add("female");
setCityList(cityList);

Answer 2

You can use select tag to display the dropdown. If you put a value attribute to the tag, the option with that value will be pre-selected.

<s:select name="fieldTwo" id="fieldTwo" list="{'Male','Female'}" headerKey="-1" headerValue="Select" value="%{fieldTwo}" />
