Re: requirments for the scratch webpage

You need to have Java installed on your computer in order to see projects online.  Go to www.java.com - they have a test you can run there to see if your computer is set up with Java.  If not, you can download it from there.

A very easy way to determine if Java is properly installed on a computer is to open a command prompt window and enter the command java at the prompt.  If Java is properly installed, something similar to the following, with the exact format depending on the version of Java, will be displayed:

C:\jnk>java
Usage: java [-options] class [args...]
           (to execute a class)
   or  java [-options] -jar jarfile [args...]
           (to execute a jar file)

where options include:
    -client       to select the "client" VM
    -server       to select the "server" VM
    -hotspot      is a synonym for the "client" VM  [deprecated]
                  The default VM is client.

    -cp <class search path of directories and zip/jar files>
    -classpath <class search path of directories and zip/jar files>
                  A ; separated list of directories, JAR archives,
                  and ZIP archives to search for class files.
    -D<name>=<value>
                  set a system property
    -verbose[:class|gc|jni]
                  enable verbose output
    -version      print product version and exit
    -version:<value>
                  require the specified version to run
    -showversion  print product version and continue
    -jre-restrict-search | -jre-no-restrict-search
                  include/exclude user private JREs in the version search
    -? -help      print this help message
    -X            print help on non-standard options
    -ea[:<packagename>...|:<classname>]
    -enableassertions[:<packagename>...|:<classname>]
                  enable assertions
    -da[:<packagename>...|:<classname>]
    -disableassertions[:<packagename>...|:<classname>]
                  disable assertions
    -esa | -enablesystemassertions
                  enable system assertions
    -dsa | -disablesystemassertions
                  disable system assertions
    -agentlib:<libname>[=<options>]
                  load native agent library <libname>, e.g. -agentlib:hprof
                    see also, -agentlib:jdwp=help and -agentlib:hprof=help
    -agentpath:<pathname>[=<options>]
                  load native agent library by full pathname
    -javaagent:<jarpath>[=<options>]
                  load Java programming language agent, see java.lang.instrument
    -splash:<imagepath>
                  show splash screen with specified image

C:\jnk>

Note that I said properly installed.  Java could be present on the machine but not properly installed or could be missing entirely.  In that case, something similar to the following will be displayed:

C:\jnk>java
'java' is not recognized as an internal or external command,
operable program or batch file.

C:\jnk>

The above assumes a Windows operating system.  Other operating systems may produce something different.
