populating drop down list from database table

hi

I am sorry that i posted this topic previously in wrong forums. please excuse me for that.

I am using jsf.

i have following questions:
1) How can we populate a drop down list from a database table? My drop down list should contain all the section numbers that satisfy a particular condition. I have written a query that would fetch all the correct section numbers. Now I want to add them into a drop down menu. Can someone tell me any way to achieve it?

2) Is there any way by which we can populate a drop down using all the elements in the array? For example:
Let the array be
String s []={"abc","def","xyz"};
How do i get the three string instances into the drop down menu?

3) Any other data structure (HashMap or Hashtable) will also do.

Sample code would help.

Thanks

Hi,
I hope I understood you correctly, unless it has been answered somewhere else,here's how I solved it: so you create the component GUI and bind it to the managed bean that fetches the info from the DB.
In my case I needed a class that fetches several country names, the final result looks like this:

The gui component:
<blockquote>code:

</blockquote>
The CountriesBean.java class is declared in faces-config.xml like this:
<blockquote>code:

<pre name="code" class="core">
<managed-bean>
<managed-bean-name>Countries</managed-bean-name>
<managed-bean-class>xlinuks.Countries</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
</pre>

</blockquote>
Its source code:
<blockquote>code:

<pre name="code" class="core">
package xlinuks;

import javax.faces.model.*;
import java.util.*;

public class Countries {

List<String> selectedItems; // + getter + setter
List<SelectItem> selectItems; // + getter only

public Countries() {
}

public List<SelectItem> getSelectItems() {

if( selectItems == null ) {
//so it actually calls another class called Connector
//that fetches the data from the DB
selectItems = Connector.getCountries( language );
}

return selectItems;
}

public void setSelectItems( List<SelectItem> selectItems ) {
this.selectItems = selectItems;
}

public List<String> getSelectedItems() {
return selectedItems;
}

public void setSelectedItems( List<String> selectedItems ) {
this.selectedItems = selectedItems;
}
}
</pre>

These are the main steps, unfortunately I can't post a detailed description.
