Catching java.sql.SQLException:

Question

ok this might be a stupid question
but say i had a dataTable populated by a resultSet,
when i update the dataTable how i can catch the java.sql.SQLException's being thrown
i.e the PK exception
i know i could catch it in the web.xml but was wondering if i can catch it in my bean?

Oh boy. You may want to go back and take Sun's exception tutorial. It's a fundamental concept. That having been said:
String sql = "some spiffy SQL goes here";
Connection conn = null;  // initialize in a spiffy way
PreparedStatememt stmt = null;
try {
   stmt = conn.prepareStatement(sql);
   stmt.executeUpdate();  // assume an exception will be thrown
catch (SQLException e) {
   e.printStackTrace();  // handle error processing
finally {
  // ensure all resources are released regardless of success or failure
   if (stmt != null) try { stmt.close(); } catch (SQLException ignore) { ignore.printStackTrace() }
  if (conn != null) try { conn.close(); } catch (SQLException ignore) { ignore.printStackTrace() }
