Problem with for multiple select

[kiranuw]

@Entity
@Table(name="Employee")
public class Caste implements Serializable
{
	
	private static final long serialVersionUID = 1L;

	@Id
	@Column(name = "dept_id")
	private Integer deptId;

	@Column(name = "emp_ids")
	private String empIds;
}

in jsp

<form:select multiple="true" path="empIds">
    <form:options items="${empisOptionList}" itemValue="empId" itemLabel="empName"/>
<form:select>

in the above code empIds are stored as comma separated ids selected by multiple select . but when i select one value
it show one value selected after saving the domain object but when more than 1 value i.e. comma separated values are save it doesn't show these value selected. and when i again update the table it save null.

Please help.

let me know how i can show more than one value selected in the multiple select when my path variable contains comma separated values e.g.2,3,4.

Thank you in advance!!!
