Error on inserting data from a comboBox

[Patrick Mugabe]

Hi, ranchers!!!
I would like to insert selected data from a comboBox into my database.
I have tried using:
String insertData = "Insert into Test " +
"Values(?, ?)";
PreparedStatement ps = con.prepareStatement(insert data);
int i =0;
ps.setString(++i, txtFullName.getText());
ps.setString(++i, (String)comboDeptID.getText());
ps.executeUpdate();
However, this is not working out and the error I am getting is that "String will be truncated". How can I get over this, Is there any better way of getting through this.
Also, what approach should I use if I am to select data from a ListBox.

Not to worry, I figured out my mistake. I had allocated a small variable size for the column that takes the selected value of the comboBox. My code is OK then.
