Steps for Creating a simple bean

Creating a simple Bean Compiling and saving the Bean into a Java Archive

(JAR) file Loading the Bean into the ToolBox Dropping a Bean instance into the BeanBox Inspecting the Bean's properties, methods, and events Generating an introspection report

The Bean will be named SimpleBean.

Here are the steps to create it and view it in the BeanBox: -

Write the SimpleBean code.

Put it in a file named SimpleBean.java, in the directory of the choice. Here's the code:

1. impot java.awt.*;2. import java.io.Serializable;3.

4. public class SimpleBean extends Canvas5. implements Serializable6. {7. //Constructor sets inherited properties8. public SimpleBean(){9. setSize(60,40);10. setBackground(Color.red);11. }12. }

SimpleBean extends the java.awt.Canvas component. SimpleBean also implements the java.io.Serializable interface, a requirement for all Beans. SimpleBean sets the background color and component size.Make sure the CLASSPATH environment variable is set to point to all needed .class (or .jar) files.

Compile the Bean:

javac SimpleBean.java

This produces the class file SimpleBean.class

Create a manifest file. Use the favorite text editor to create a file, we'll call it manifest.tmp, that contains the following text:

Name: SimpleBean.classJava-Bean: True

Create the JAR file. The JAR file will contain the manifest and the SimpleBean class file:

jar cfm SimpleBean.jar manifest.tmp SimpleBean.class

Load the JAR file into the ToolBox. Select the File|LoadJar... menu item. This will bring up a file browser. Navigate to the SimpleBean.jar location and select it. SimpleBean will appear at

http://java.sun.com/javase/6/docs/api/java/awt/Canvas.html

http://java.sun.com/javase/6/docs/api/java/io/Serializable.html

the bottom of the ToolBox. (Note that when the BeanBox is started, all Beans in JAR files in the beans/jars directory are automatically loaded into the ToolBox).

Drop a SimpleBean instance into the BeanBox. Click on the word SimpleBean in the ToolBox. The cursor will change to a crosshair. Move the cursor to a spot within the BeanBox and click. SimpleBean will appear as a painted rectangle with a hatched border. This border means that SimpleBean is selected. The SimpleBean properties will appear in the Properties sheet.

You can resize SimpleBean, because it inherits from Canvas, by dragging a corner. You will see the cursor change to a right angle when over a corner. You can also reposition SimpleBean within the BeanBox by dragging on any non-corner portion of the hatched border. You will see the cursor change to crossed arrows when in position to move the Bean. EXAMPLE OF ACTION ELEMENT: USEBEAN, GETPROPERTY
