I am dynamically constructing a dataTable.
The main problem is the command link xpathLink, which cannot enter the testing method, ShowResult is a page bean.
Can someone help me out?

This is method testing().
public void testing() {
JOptionPane.showMessageDialog(null, "in function testing");
String in ="success";
//return in;
}

Did you make the bean scope as "session"?

Yes, i changed the ShowResult into session scope. But when i click on the link. It still can't work. just the data on the table remains.
