public void actionPerformed(ActionEvent e) {
    // TODO Auto-generated method stub

    String s1,s2,s3,s4,s5,s6,s7;
    int i;

Your sql string is improperly formatted. There should be spaces between all the commands and names and if you want to load the values of s1, s2, . . . into the database you need to treat them as variable concatenations to a string. Also surrounding each value with ' and each column with " allows the value and names to contain spaces.

Try something like this:

statement.executeUpdate("INSERT INTO incident "
+ "(ticket_no, date, description, priority,state,follow_up,status) "
+ "values " + "(\'" + s1 + "\', \'" + s2 + "\', \'" + s3 + "\', \'"
+ i + "\', \'"+ s5 + "\', \'" + s6 + "\', \'" + s7 + "\')");

Yes DarkLighting7 is right that between every commands there must be space.Add space before values.
But there is one error in your code.Integer must not be enclosed with quotes.Also i think so escape symbol is not required here.

statement.executeUpdate("INSERT INTO incident"
            + "(ticket_no, date, description, priority,state,follow_up,status) "
            + "values('" + s1 + "','" + s2 + "', '" + s3 + "', "
            + i + ", '"+ s5 + "', '" + s6 + "', '" + s7 + "')");

Thanks for pointing the integer out completely forgot about it. I wasn't sure about the escape characters so i added them just in case. Thanks for correcting me will save some time in the future. :)
