Notes 01 - Hello World

In this tutorial you will learn how to use the ]project-open[ development environment and to create your first "Hello World" example.

Development Environment

You will need as a precondition:

• A running ]po[ server:
  You could download the VMware or the Windows installer (future) from our SourceForge site -> Downloads section.
  
• Browser access to the ]po[ server:
  Please configure your VMware in such a way, that you can access the ]po[ from your host machine.
• Edit files in the ]po[ server:
  On Linux you can use Emacs or Vi. On Windows you can use any local editor. We recommend TextPad for editing.
• Browsing the ~/log/errors.log” file:
  On Linux you can use "tail -f ~/log/errors.log", on Windows you can use TextPad to display the contents of the log file.
  

Once everything is set up please use your text editor and create a new file called "notes01.tcl" in the ~/www/ directory with the following single line:

doc_return 200 "text/html" "Hello World"

Now point your browser at the file by entering the URL: "http://localhost/notes01".

You should see a beautiful "Hello World" in your browser. Congratulations!
