Creating a Java Scrapbook Page

The scrapbook allows Java expressions, to be run, inspected, and displayed under the control of the debugger. Breakpoints and exceptions behave as they do in a regular debug session.

Code is edited on a scrapbook page.  A VM is launched for each scrapbook page in which expressions are being evaluated. The first time an expression is evaluated in a scrapbook page after it is opened, a VM is launched. The VM for a page will remain active until the page is closed, terminated explicitly (in the debugger or via the Stop the Evaluation button in the editor toolbar), or when a System.exit() is evaluated.

There are several ways to open the New Java Scrapbook Page wizard.

• Create a file with a .jpage extension
• From the menu bar, select File > New > Other.... Then select Java > Java Run/Debug > Scrapbook Page. Then click Next.

1. In the Enter or select the folder field, type or click Browse to select the container for the new page.
2. In the File name field, type a name for the new page. The .jpage extension will be added automatically if you do not type it yourself.
3. Click Finish when you are done. The new scrapbook page opens in an editor.
