passing values of Select box from JSP to Action class thru form Bean

Short answer for @saivemuri: the select control must post a parameter whose name exactly matches a property on the ActionForm, and the property type must match the HTML control (single select -> String; multi-select -> String[]). Letting Struts populate the form bean is cleaner than manually calling request.getParameter(...); @peter_budo’s pointer about parameter vs parameterValues is useful for debugging, but the framework will do that wiring automatically when names and setters match.

Example ActionForm:

public class MyForm extends ActionForm {
  private String country;        // single select
  private String[] colors;       // multiple select

  public String getCountry() { return country; }
  public void setCountry(String country) { this.country = country; }

  public String[] getColors() { return colors; }
  public void setColors(String[] colors) { this.colors = colors; }
}

Example JSP (Struts tag and plain HTML):

<html:form action="/save">
  <html:select property="country">
    <html:option value="US">United States</html:option>
    ...
  </html:select>

  <select name="colors" multiple="true">
    <option value="red">Red</option>
    <option value="green">Green</option>
  </select>

  <html:submit/>
</html:form>

Action execute snippet (how to read the bean):

public ActionForward execute(ActionMapping mapping, ActionForm form,
    HttpServletRequest request, HttpServletResponse response) {
  MyForm f = (MyForm) form;
  System.out.println("country=" + f.getCountry());
  System.out.println("colors=" + Arrays.toString(f.getColors()));
  ...
}

Quick checklist/troubleshooting:

• Confirm the <action> mapping name matches the <form-bean> name in struts-config and set scope="request" if sessions are not allowed.
• Ensure select name (or property in Struts tags) exactly matches the form bean property and that public setter exists.
• Use String for single selects, String[] for multi-selects.
• Make sure each <option> has a value attribute (that value is what gets posted).
• For session-scoped forms override reset() to clear arrays/checkboxes; for request scope a new form is built each request.
• To debug, dump request.getParameterMap() or log Arrays.toString(request.getParameterValues("colors")) to see what the browser actually sent.

Referencing @mukeshky and @Labs: if multiple selection behavior is unclear, confirm how the browser selects values (Ctrl/Shift on most OSs) and then check the submitted parameter array as above.
