Drop-down in JSP using a bean as back-end

Question

Hi everyone,
I like to create a dynamic drop-down (reading from a database) using JSP but accessing a bean. My code on the bean is:
public void DepartmentName() {
try
stmt1 = tConnection.createStatement();
rs1 = stmt1.executeQuery ("select DEPT_NAME from DEPARTMENT");
while ( rs1.next() )
String DptName = rs1.getString("DEPT_NAME");
System.out.println(DptName);
Can anybody tell me how to call this DepartmentName bean in JSP? So far my JSP looks like this...
<table width="100%"><tr>
<form action="next.jsp" method="POST">
<input type="hidden" name="type" value="listemp">
<td width="100">
<b>Department</b></td>
<td wifth="100">
<SELECT name=cust multiple size=4>
<option>??????? HELP ???????????</option>
</SELECT>
</td>
<td><input type="submit" value="Submit" name="dept">
</td></tr></table>
Many thanks.

First you need to modify your bean to return some sort of data structure of String objects. How about a Vector? Then you could call Vector.elements() on the return statement of the DepartmentName() method, like this...
public Enumeration DepartmentName()
  Vector myVector = new Vector(0);
  while(rs.next())
    myVector.add(rs.getString(1));
  return myVector.elements();
}Then in your JSP you'll need to use the JSP useBean tag
<jsp:useBean id="myBean" class="com.myco.myapp.MyBean" scope="page|request|session|application" />And before the option tag call the bean and get the enumeration of String objects, then loop through them like this:
while(enum.hasMoreElements())
  out.println(((String) enum.nextElement()));
}
