If you have a CSV (or TSV) that you need to display in a JTable then you should have a look at the TableModelExtTextLoader class from SwingLabs.

It provides all you should need and save you the hassle of reinventing the wheel and using a half baked CSV implementation.

Here is an example of it’s usage.

URL csv = new URL("http://myapp/employees.csv");
DefaultTableModelExt data = new DefaultTableModelExt(url);
TableModelExtTextLoader loader = 
        new TableModelExtTextLoader(",", false, 75);
data.setLoader(loader);
data.startLoading();

As many of you will probably have a file from disk that you want to load then see “How to convert a File to a URL”

MacOS caches the result of DNS lookups to improve performance. If you wanted to flush this cache you used the following command with Tiger:

lookupd -flushcache

With the release of Leopard the required command changed to the following:

dscacheutil -flushcache
