Trail: JDBC Database Access
Lesson: JDBC Basics

## Running the Sample Applications

> You are now ready to actually try out some sample code. The directory `book.html` contains complete, runnable applications that illustrate concepts presented in this chapter and the next. You can download this sample code from the JDBC web site located at:

> >     http://www.javasoft.com/products/jdbc/book.html

> Before you can run one of these applications, you will need to edit the file by substituting the appropriate information for the following variables:

> `url`
>   the JDBC URL; parts one and two are supplied by your driver, and the third part specifies your data source
> `myLogin`
>   your login name or user name
> `myPassword`
>   your password for the DBMS
> `myDriver.ClassName`
>   the class name supplied with your driver

> The first example application is the class `CreateCoffees` , which is in a file named `CreateCoffees.java`. Below are instructions for running `CreateCoffees.java` on the three major platforms.

> The first line in the instructions below compiles the code in the file `CreateCoffees.java` . If the compilation is successful, it will produce a file named `CreateCoffees.class` , which contains the bytecodes translated from the file `CreateCoffees.java` . These bytecodes will be interpreted by the Java Virtual Machine, which is what makes it possible for Java code to run on any machine with a Java Virtual Machine installed on it.

> The second line of code is what actually makes the code run. Note that you use the name of the class, `CreateCoffees` , not the name of the file, `CreateCoffees.class` .

> `UNIX`

>   >     javac CreateCoffees.java
>   >     java CreateCoffees

> `Windows 95/NT`

>   >     javac CreateCoffees.java
>   >     java CreateCoffees
