TableModel extends DefaultTableModel. Now the ResultViewer.java class that I have is supposed to display the names of files and their properties in 3 columns. The ResultViewer is supposed to update after every 20 secs. The problem is that when an update occurs, an ArrayIndexOutOfBoundsException occurs. I think that the array references a null pointer in the vector when its updating. The update occurs by 1st clearing the existing table then updating it. I think when the update occrus here it references null. Its more of a logical error. public void clearTable () { for (int row = (table.getRowCount() -1) ; row >= 0; row--) { ((DefaultTableModel) table.getModel()).removeRow(row); } } I've already tried the fireTableRowsUpdated method and it doesn't seem to work.

But there's a way the get a synchronized one as mentioned in java.util.ArrayList's JavaDoc: List list = Collections.synchronizedList(new ArrayList(...)); In java.util.Collections' JavaDoc you can read that "It is imperative that the user manually synchronize on the returned list when iterating over it:" synchronized(list) { Iterator i = list.iterator(); // Must be in synchronized block while (i.hasNext()) foo(i.next()); } Using a synchronized ArrayList results in additional work, why not use a java.util.Vector instead?

If you don't have method signatures defined in the interface for non-select operation you don't need to provide an implementation.

Internet explorer and Netscape are showing all of the pages that are passing from tomcat and have Greek with wildcards quetionmarks etc. When data is received from the database it is being displayed correctly (Only static data is not displayed normally). Well the setup is allright (web.xml, in every file of the site). The encoding is Greek allright but something is happening with HTML. Can anyone help me because this situation has been very annoying at least!
