Well lets say I have a customers table.  In a session bean I have this
function that creates an ID for me.  Do I have concurrency problems with
this?

private int getID() throws SQLException, NamingException {
    Connection conn = getConnection();
    Statement stmt = conn.createStatement();
    ResultSet rs = stmt.executeQuery("SELECT MAX(ID+1) FROM CUSTOMERS");

    rs.next();
    int i = rs.getInt(1);
    stmt.close();
    return i;
}

It works like a champ.  Granted I need better handling of the
Exceptions.  But the question is concurrency will this pose a problem?

P.S. If anyone is a manager of this newsgroup I always get a legg@...
someone or rather is not a valid email box.  Can someone drop this
person?
