 general instructions


 editing

 you can use either BBEdit or SimpleText to edit
 the text documents. create a local folder where to
 store the files.


 ftp

 you can use either the Save to FTP-server command
 in BBEdit or a program called Fetch to move the
 files to and from the uiah server.


 directories

 always create a new directory when you start
 doing something new. place all these directories
 under public_html/java99 directory.


 backups

 always when you get something done that you would like
 to save, make a backup directory! this is a simple
 thing to do in unix:

	- cp  -R  directory_name  backup_directory_name


 file permissions

 if you get an error 'Forbidden,  You don't have
 permission to access...' in the browser, you
 should change the permissions of the files
 and directories. the easiest way to do this is:

	- cd
	- chmod  -R  a+rx  public_html


 compiling

 all the java source files should have .java extensions.

 to compile the files, change the location to the directory
 where the .java files are (cd directory_name). then use the
 'javac' (java compiler) command to compile all the files.
 the command that compiles all the .java files in a directory is:
 
        javac  *.java

 the resulting compiled files have .class extensions,
 which can be referenced in .html files.
