Assuming you are using a setPage() method of JEditorPane, the event dispatch thread is blocked while the page is fetched. Using SwingWorker is a reasonable alternative.

Addendum: SwingWorker is convenient for showing progress; but as an alternative, you might look into the asynchronous feature of setPage() using setAsynchronousLoadPriority().
