Trying to use XMLTreeDataBuilder Class but having problems
I think I am close to doing this correctly, but I must be doing somethign wrong.
Here is my XmlTreeDataBuilder Class:
package testContainer;
import org.richfaces.model.TreeNode;
import org.richfaces.component.xml.XmlTreeDataBuilder;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
import java.io.IOException;
public class XMLTreeDataBuilderTest {
private TreeNode data;
public XMLTreeDataBuilderTest () throws SAXException, IOException {
data = XmlTreeDataBuilder.build(new InputSource(getClass().getResourceAsStream("songs.xml")));
}
public void setData(TreeNode data) {
this.data = data;
}
public TreeNode getData() {
return data;
}
}Here is the songs.xml file it refers to:
<?xml version="1.0" encoding="UTF-8"?> <songs> <song>List</song> <song>Dance</song> <song>It</song> <song>Eyes</song> <song>Up</song> </songs>
And finally my xhml page:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:a4j="http://richfaces.org/a4j"
xmlns:rich="http://richfaces.org/rich"
xmlns:ui="http://java.sun.com/jsf/facelets">
<body>
<h:form>
<rich:tree style="width:300px" switchType="ajax" >
<rich:recursiveTreeNodesAdaptor roots="#{nodesBean.data}" var="data" nodes="#{nodesBean.data}" />
</rich:tree>
</h:form>
</body>
</html>plus I of course have a managed bean:
<managed-bean> <managed-bean-name>nodesBean</managed-bean-name> <managed-bean-class>testContainer.XMLTreeDataBuilderTest</managed-bean-class> <managed-bean-scope>session</managed-bean-scope> </managed-bean>
But when I try to run this on my server I get:
HTTP Status 500 -
