The class path value in use during your Web target session depends on how the Java VM starts. PowerBuilder starts the Java VM in these situations:
The first time you look at a page that contains a Java applet, the Java VM starts automatically using the default system class path. The system options class path is not used.
When you expand a Java branch on the Components tab of the System Tree, the Java VM starts using a combination of the system options and system default class paths.
Once the Java VM is started, it remains running until you exit your workspace.
When you include a Java applet in your document, the Applet element provides a CODEBASE attribute that specifies where to find the applet on the server. The class path setting on the user's computer is irrelevant.
Viewing results of class path changes in the System Tree If you use the Java tab of the System Options dialog box to change the class path after the Java VM is started in your current session, you must restart PowerBuilder to see the result. Even then, your changes take effect only after the Java VM starts as a result of actions in the System Tree.
