This is scottn's code, not mine.
The 1 simply means true, which in the pattern/expression part causes the execution of the default action, which is print the current record.

gappletviewer

GAPPLETVIEWER(1)                                                        GNU                                                       GAPPLETVIEWER(1)

NAME

       gappletviewer - Load and runs an applet

SYNOPSIS

       appletviewer [OPTION]... URL...

       appletviewer [OPTION]... -code CODE

       appletviewer [OPTION]... -plugin INPUT,OUTPUT

DESCRIPTION

       The appletviewer tool loads and runs an applet.

       Use the first form to test applets specified by tag.  The URL should resolve to an HTML document from which the appletviewer will extract
       applet tags.  The APPLET, EMBED and OBJECT tags are supported.  If a given document contains multiple applet tags, all the applets will be
       loaded, with each applet appearing in its own window.  Likewise, when multiple URLs are specified, each applet tag instance is given its
       own window.  If a given document contains no recognized tags the appletviewer does nothing.

               appletviewer http://www.gnu.org/software/classpath/

       Use the second form to test an applet in development.  This form allows applet tag attributes to be supplied on the command line.  Only one
       applet may be specified using the -code option.  The -code option overrides the URL form -- any URLs specified will be ignored.

               appletviewer -code Test.class -param datafile,data.txt

       gcjwebplugin uses the third form to communicate with the appletviewer through named pipes.

OPTIONS

       URL OPTIONS

       -debug
           This option is not yet implemented but is provided for compatibility.

       -encoding CHARSET
           Use this option to specify an alternate character encoding for the specified HTML page.

       APPLET TAG OPTIONS

       -code CODE
           Use the -code option to specify the value of the applet tag CODE attribute.

       -codebase CODEBASE
           Use the -codebase option to specify the value of the applet tag CODEBASE attribute.

       -archive ARCHIVE
           Use the -archive option to specify the value of the applet tag ARCHIVE attribute.

       -width WIDTH
           Use the -width option to specify the value of the applet tag WIDTH attribute.

       -height HEIGHT
           Use the -height option to specify the value of the applet tag HEIGHT attribute.

       -param NAME,VALUE
           Use the -param option to specify values for the NAME and VALUE attributes of an applet PARAM tag.

       PLUGIN OPTION

       -plugin INPUT,OUTPUT
           gcjwebplugin uses the -plugin option to specify the named pipe the appletviewer should use for receiving commands (INPUT) and the one
           it should use for sending commands to gcjwebplugin (OUTPUT).

       DEBUGGING OPTION

       -verbose
           Use the -verbose option to have the appletviewer print debugging messages.

       STANDARD OPTIONS

       -help
           Use the -help option to have the appletviewer print a usage message, then exit.

       -version
           Use the -version option to have the appletviewer print its version, then exit.

       -JOPTION
           Use the -J option to pass OPTION to the virtual machine that will run the appletviewer.  Unlike other options, there must not be a
           space between the -J and OPTION.
