Description

Java is a programming language that allows developers to create programs that can run on any platform, including Windows, Unix, and MacOS. Since Java applications (.class files) aren’t formal Windows programs, they can’t be opened by themselves; rather, you must use the Java Command-Line Loader to run them. The exceptions are so-called Java applets, which are Java programs included in web pages and run internally by your web browser.

Windows XP comes with two Java command-line loaders, jview.exe and wjview.exe. Both versions do the same thing and accept exactly the same parameters (see below). The difference is that jview.exe is a command-line-based program and wjview.exe is a Windows-based program. The Java Command-Line Loader takes the following options:

classname

The full path and filename of the .class file to be executed.

/a

Executes AppletViewer.

/d:< name >=< value >

Defines a system variable to be used by the Java program.

/n < namespace >

The namespace in which to run.

/p

Pauses before terminating if an error occurs.

/v

Verifies the Java program before executing it.

arguments

The command-line arguments to be passed onto the Java program.

/vst

Prints verbose stack traces (requires debug classes).

/cp
