>
> public ModulePathForm(){
> super();
> folders = null;
> selectedFolders = null;
> }
> public ArrayList getFolders() {
> return this.folders;
> }
>
> public void setFolders(ArrayList folders) {
> this.folders = folders;
> }
>
> public String getSelectedFolders(int index) {
> return this.selectedFolders[index];
> }
>
> public String[] getSelectedFolders() {
> return this.selectedFolders;
> }
>
> public void setSelectedFolders(int index, String selectedFolders) {
> this.selectedFolders[index] = selectedFolders;
> }
>
> public void setSelectedFolders(String[] selectedFolders) {
> this.selectedFolders = selectedFolders;
> }
> }
> and following code in my jsp:
> <html:select property="selectedFolders" multiple="true">
