How get datas???

Question

Hi..
I have some problems with getting data s from any action .I define global variable and assign null value. In some action I get data s and in that action I assign this data s to global variable.But when I call that value out of this action it returns null value. I can't understand why in action the variable can't get values. Maybe I need getter????
Thank in advise.

I define this variable as a global.
private Object tablename;
tree.addTreeSelectionListener(new TreeSelectionListener() {
public void valueChanged(TreeSelectionEvent e) {
DefaultMutableTreeNode node = (DefaultMutableTreeNode) tree.tree.getLastSelectedPathComponent();
tablename = tree.getLastSelectedPathComponent();
if (node == null) {
return;
Object nodeinfo = node.getUserObject();
String name = String.valueOf(nodeinfo);
}
