Struts actionform and checkboxes

Question

hi!
I'm having trouble creating an actionform for a jsp that i have. Basically, my jsp lists files which have their corresponding checkboxes. The user can click multiple checkbox representing the files he wants to download. On clicking the download button, it submits it to my DownloadAction.
My problem is that only the first checkbox is stored in my actionform.
here's my actionform:
package mybeans;
import org.apache.struts.action.ActionForm;
import java.util.*;
public class FilesForm extends ActionForm
    Vector files = new Vector();
    String file = null;
    public String getFile() {
         System.out.println( "getting file" );
         return file;
    public void setFile( String string ) {  
         System.out.println( "setting file" );      
         file += string + ",";
         files.add( string );
    public Vector getFiles() {
         return files;
}my jsp is a bit big. here's the form part:
<html:form action="/download">
  <table>
    <tr>
      <td><input type="checkbox" name="file" value="someDynamicID"></td>
      <td>filename</td>
    </tr>
  ...more files here...
  </table>
</html:form>Thanks in advance!

Answer 1

Make your setter take a String[] argument and your getter return a String[] argument (I think List or Set might also work).
