JDBC, Java Server Pages, and MySQL Questions and Answers

Q: Which JDBC driver Type(s) can be used in either applet or servlet code?

Correct answer: Both Type 3 and Type 4Applets and servlets both need a driver that can work over a network without native code installed on the machine. Type 3 speaks to a middleware server and Type 4 speaks the DBMS protocol directly, and both are pure Java. Types 1 and 2 depend on ODBC or a native client library being present locally, which an applet cannot assume.

Q: With JSP, the coding is done in Java and only in Java.

Correct answer: TrueJSP supports Java and no other language, so every scriptlet, expression and declaration on the page is Java. This is a genuine difference from ASP, which accepts VBScript and JScript, and it is why the resemblance between the two technologies is confined to their appearance on the page.
