Hi,

I am using JList component and I add a vector of data by calling
list.setDataList( vec );

Then I fire up the dialog with the JList component in it, I would like
to hard-code it to highlight the very first data on the list, how can I
go about doing that?

From the JList documentation:

<api>
public void setSelectedIndex(int index)

Selects a single cell.
</api>

Bye

Read the fine manual at

http://java.sun.com/j2se/1.5.0/docs/api/javax/swing/JList.html#setSelectedIndex(int)

You can use

list.setSelectedIndex(0);
