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.
Once you've opened the New Java Scrapbook Page wizard:.
- In the Enter or select the folder field, type or click Browse to select the container for the new page.
- 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.
- Click Finish when you are done. The new scrapbook page opens in an editor.
