Trouble with struts tags

Question

Hi,
I am new to struts and am getting confused with the tags.
I have few doubts.
My Actionform would be -
public class AForm extends ActionForm {
    //~ Instance fields ********************************************************
    String deptNo;
    String dName;
    String loc;
    //~ Methods ****************************************************************
     * This function
     * @param deptNo DOCUMENT ME!
    public void setDeptNo(String deptNo) {
        this.deptNo = deptNo;
     * This function
     * @return DOCUMENT ME!
    public String getDeptNo() {
        return deptNo;
    }In my action class I say -
selectSql = "SELECT DEPTNO FROM DEPT";
                pStmt = conn.prepareStatement(selectSql);
                theResultSet = pStmt.executeQuery();
                ArrayList _arrayList = new ArrayList();
                 while (theResultSet.next()) {
                    AForm theAForm = new AForm();
                    theAForm.setDeptNo(theResultSet.getString("DEPTNO"));
                    _arrayList.add(theAForm);
                req.setAttribute("arrayListOfDeptnos", _arrayList);My question is -
How do I get this arraylist in the JSP and iterate through it? Should I code in this way? Is there an more elegant way to do it??
My JSP page
<%   
          java.util.ArrayList ss = (java.util.ArrayList)request.getAttribute("arrayListOfDeptnos");
          if(ss!=null){
    %>
      <logic:iterate id="booId" scope="request" collection="<%=ss%>" type="mypackage27.AForm">
        <html:link action="/getme" paramId="theNum" paramProperty="deptNo" paramName="booId">
          <bean:write name="booId" property="deptNo"/>
        </html:link>
      </logic:iterate>
      <%  
    %>I know this must be very trivial ...

Answer 1

Rather than using collection attribute (which requires a runtime expression) instead use the name attribute.
Also, if you aren't going to use the variable "booId" in scriptlet code/expressions, you can leave out the "type" attribute.
Probably the scope attribute as well.
That all boils down to:
<logic:iterate id="booId" name="arrayListOfDeptnos">
  <html:link action="/getme" paramId="theNum" paramProperty="deptNo" paramName="booId">
    <bean:write name="booId" property="deptNo"/>
  </html:link>
</logic:iterate>And for completeness, the same thing using some JSTL code:
<c:forEach var="booId" items="${requestScope.namearrayListOfDeptnos}">
  <html:link action="/getme" paramId="theNum" paramProperty="deptNo" paramName="booId">
    <c:out value="${booId.deptNo}"/>
  </html:link>
</c:forEach>Cheers,
