print java bean list in jsp

Question

I have one method, this method returnes a list of items, inside java bean it works now I want to print the output of the method inside jsp, but I searched a lot couldn't find something useful, if someone can help me I really appreciated this is my method for print a list

public static List printDirect() {
    List returned_list = new ArrayList ();

    //StringBuilder text=new  StringBuilder();
    manager = OntologyManagement.ontology.getOWLOntologyManager();
    factory = manager.getOWLDataFactory();

    reasonerFactory = new StructuralReasonerFactory();
    progressMonitor = new ConsoleProgressMonitor();
    config = new SimpleConfiguration(progressMonitor);
    reasoner = reasonerFactory.createReasoner(ontology, config);
    // Ask the reasoner to do all the necessary work now
    reasoner.precomputeInferences();
    OWLClass thing = factory.getOWLThing();
    NodeSet<OWLClass> subClses = reasoner.getSubClasses(thing, true);
    Set<OWLClass> clses = subClses.getFlattened();
    System.out.println("Subclasses of owl:thing =  ");
    for (OWLClass cls : clses) {
        String row = cls.toString();
        String[] split = row.split("#");
        String word = split[1].substring(0, (split[1].length() -1));
        returned_list.add(word);
        System.out.println("    " + word);
    }
    return returned_list;
}

Answer 1

First get the List object in jsp like this

<%
    List list = fullQualifiedClassName.printDirect();
%>

Then iterate over the listObject using JSTL

<c:forEach items="${list}" var="item">
    ${item}<br>
</c:forEach>

Dont forget to add this along with the necessary imports

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

You can even use simple Scriptlets to iterate over the List(But it is not Recommended)

<% for (int i=0;i<list.size();i++)
  {
     out.println(list.get(i));  
  } 
%>

or

<%  Iterator iterator = list.iterator();
    while (iterator.hasNext()) {    
        out.println(iterator.next());
    }
 %>
