Java Database Connectivity (JDBC)

Hiya

Was wondering if anyone knew how to use variables from an html form into a sql insert into statement? The constants work ok below, its just getting the variables to work.




//constants work ok.
rs = stmt.executeQuery("INSERT INTO ACCOUNTS " + " VALUES ('un', 'test2', 'test2', 'test2', 'test', 'test', 'test', 'test', 'test')");




//doesn't do anything no errors.

rs = stmt.executeQuery("INSERT INTO ACCOUNTS " + " VALUES ( '"+uname+"', " + " '"+fname+"', " + " '"+sname+"'," + "'"+address1+"'," + "'"+address2+"'," + "'"+town+"'," + "'"+county+"'," + "'"+postcode+"')");
