Q.How to create a multiple selections list in Struts? and retrive seleted values ?

Click to View Answer Below

!!!Answer!!!- From Technical Expert

This is the code to display multiple selections list and retrive seleted values in struts.
medList list contains list of Medium objects.

Java :
bean class.
public class Medium {
    int medId;
    String medName;

    /**
     * @return Returns the medId.
     */
    public int getMedId() {
        return medId;
    }
    /**
     * @param medId The medId to set.
     */
    public void setMedId(int medId) {
        this.medId = medId;
    }
    /**
     * @return Returns the medName.
     */
    public String getMedName() {
        return medName;
    }
    /**
     * @param medName The medName to set.
     */
    public void setMedName(String medName) {
        this.medName = medName;
    }
}

In the Form Class :

public class MediumForm {
private List medList;
private String[] med;
    public void setMedList(List medList){
        this.medList = medList;
    }

    public List getMedList(){
        return this.medList;
    }

    public String[] getMed() {
        return med;
    }

    public void setMed(String[] med) {
        this.med = med;
    }


}

In the Action class :

List medList = DAO.getMediums();
form.setMedList(medList);

DAO Class :

DAO Class to retrive mediums in data base.
public static List getMediums(){
        PreparedStatement pStmt = null;
     Connection conn = null;
     boolean success = false;
     ResultSet rs = null;
     List medList = new ArrayList();

     try{
         conn = getConnection();

         String sql = " select * from MEDIUM ";
         pStmt = conn.prepareStatement(sql);

         rs = pStmt.executeQuery();
         while(rs.next()){
             Medium med = new Medium();
             med.setMedId(rs.getInt("MED_ID"));
             med.setMedName(rs.getString("MEDIUM_NAME"));
             medList.add(med);
             }



     }catch(Exception e){
         e.printStackTrace();

     }finally{
         closeConnectionProp(conn,pStmt,rs);
     }

     return medList;

    }

JSP Struts:

<html:select name="MediumForm" property="med" multiple="true">

<bean:define name="MediumForm" property="medList" id="mlist" />
<html:options collection="mlist" property="medId" labelProperty="medName" />
</html:select>

In the Action class again :
how to retrive the selected values.

String[] med = form.getMed();
