Dear dudes,
I want to create a simple tree structure in my jsf page backed by a backing bean.
But my jsf page is getting executed but my tree is not getting displayed.
my jsf page:

My backing bean:

package org.test.tree;
 
import java.util.Iterator;
import java.util.List;
 
import org.apache.myfaces.custom.tree.DefaultMutableTreeNode;
import org.apache.myfaces.custom.tree.model.DefaultTreeModel;
 
import com.srit.framework.web.BasePage;
import com.srit.healthcare.common.lookupentity.repository.ILookupRepository;
import com.srit.healthcare.common.tree.domain.RcareTree;
 
public class MyTreebean {
private DefaultTreeModel myTree;

public DefaultTreeModel getMyTree() {

return myTree=getTreeModel();
}

public void setMyTree(DefaultTreeModel myTree) {
this.myTree = myTree;
}

/*public MyTreebean() {
DefaultMutableTreeNode root = new DefaultMutableTreeNode("XY");
DefaultMutableTreeNode a = new DefaultMutableTreeNode("A");
root.insert(a);
DefaultMutableTreeNode b = new DefaultMutableTreeNode("B");
root.insert(b);
DefaultMutableTreeNode c = new DefaultMutableTreeNode("C");
root.insert(c);
DefaultMutableTreeNode node = new DefaultMutableTreeNode("a1");
a.insert(node);
node = new DefaultMutableTreeNode("a2 ");
a.insert(node);
node = new DefaultMutableTreeNode("b ");
b.insert(node);
a = node;
node = new DefaultMutableTreeNode("x1");
a.insert(node);
node = new DefaultMutableTreeNode("x2");
a.insert(node);
myTree = new DefaultTreeModel(root);
}
*/
public DefaultTreeModel getTreeModel() {
DefaultMutableTreeNode root = new DefaultMutableTreeNode("XY");
DefaultMutableTreeNode a = new DefaultMutableTreeNode("A");
root.insert(a);
DefaultMutableTreeNode b = new DefaultMutableTreeNode("B");
root.insert(b);
DefaultMutableTreeNode c = new DefaultMutableTreeNode("C");
root.insert(c);
DefaultMutableTreeNode node = new DefaultMutableTreeNode("a1");
a.insert(node);
node = new DefaultMutableTreeNode("a2 ");
a.insert(node);
node = new DefaultMutableTreeNode("b ");
b.insert(node);
a = node;
node = new DefaultMutableTreeNode("x1");
a.insert(node);
node = new DefaultMutableTreeNode("x2");
a.insert(node);
return myTree = new DefaultTreeModel(root);
}
}

Also i've configured my tomahawk-taglib file in my web.xml .
My backing bean is configured in my faces-config.xml
But i'm not able to get my tree structure in my page .
Any help would be appreciated.
Regards

I changed my jsfpage to point to another bean which has been configured in faces-config.xml
Modified jsf page:

Now after changing my jsf page i'm getting

In another configuration file:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Error: cannot find the declaration of element 'beans'

I'm a novice to jsf technology and i don't know
why this errors are propagating and how this can be fixed?
please reply.
