3 - level folder display in struts

[Sander Evanfield]

I have to show data in Jsp the following way using logic::iterate

Category 1
SubCategory 1
rpt1-name
rpt2-name

SubCategory 2
rpt1-name
rpt2-name

Category 2
......

It is possible that subcategory could be blank in that scenario only have to show reports below Category
these are all Strings.
How do I use datastructure like HashMap and logic::iterate to acheive this

[Merrill Higginson]

I'd suggest creating a hierarchy of model objects. For example:

public class ReportForm extends ActionForm {
List<Category> categories;
// getters and setters

public class Category {
String categoryName;
List<Category> subCategories;
List<Report> reports;
// getters and setters
}

Public class Report {
String reportName;
// getters and setters
}

Then in your JSP:

<logic:iterate id="category" name="reportForm" property="categories" >
  <bean:write name="category" property="categoryName" />
  <logic:notEmpty name="category" property="subCategories">
    <logic:iterate id="subCategory" name="category" property="subCategories">
      <bean:write name="subCategory" property="categoryName" />
      <logic:iterate id="reportInSubCategory" name="subCategory" property="report">
        <bean:write name="reportInSubcategory" property="reportName" />
      </logic:iterate>
    </logic:iterate>
  </logic:notEmpty>
  <logic:notEmpty name="category" property="reports">
    <logic:iterate id="report" name="category" property="reports">
      <bean:write name="report" property="reportName" />
    </logic:iterate>
  </logic:notEmpty>
</logic:iterate>
